>gnl|CDD|173623 cd00180, PKc, Catalytic domain of Protein Kinases. Protein Kinases
(PKs), catalytic (c) domain. PKs catalyze the transfer of
the gamma-phosphoryl group from ATP to serine/threonine
or tyrosine residues on protein substrates. The PK family
is part of a larger superfamily that includes the
catalytic domains of RIO kinases, aminoglycoside
phosphotransferase, choline kinase, phosphoinositide
3-kinase (PI3K), and actin-fragmin kinase. PKs make up a
large family of serine/threonine kinases, protein
tyrosine kinases (PTKs), and dual-specificity PKs that
phosphorylate both serine/threonine and tyrosine residues
of target proteins. Majority of protein phosphorylation,
about 95%, occurs on serine residues while only 1% occurs
on tyrosine residues. Protein phosphorylation is a
mechanism by which a wide variety of cellular proteins,
such as enzymes and membrane channels, are reversibly
regulated in response to certain stimuli. PKs often
function as components of signal transduction pathways in
which one kinase activates a second kinase, which in
turn, may act on other kinases; this sequential action
transmits a signal from the cell surface to target
proteins, which results in cellular responses. The PK
family is one of the largest known protein families with
more than 100 homologous yeast enzymes and 550 human
proteins. A fraction of PK family members are
pseudokinases that lack crucial residues for catalytic
activity. The mutiplicity of kinases allows for specific
regulation according to substrate, tissue distribution,
and cellular localization. PKs regulate many cellular
processes including proliferation, division,
differentiation, motility, survival, metabolism,
cell-cycle progression, cytoskeletal rearrangement,
immunity, and neuronal functions. Many kinases are
implicated in the development of various human diseases
including different types of cancer.

Kinase, Never In Mitosis gene A-related kinase.
Serine/Threonine Kinases (STKs), Never In Mitosis gene A
(NIMA)-related kinase (Nek) family, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The Nek family is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. The Nek family is composed of
11 different mammalian members (Nek1-11) with similarity
to the catalytic domain of Aspergillus nidulans NIMA
kinase, the founding member of the Nek family which was
identified in a screen for cell cycle mutants that were
prevented from entering mitosis. Neks contain a conserved
N-terminal catalytic domain and a more divergent
C-terminal regulatory region of various sizes and
structures. They are involved in the regulation of
downstream processes following the activation of Cdc2,
and many of their functions are cell cycle-related. They
play critical roles in microtubule dynamics during
ciliogenesis and mitosis.

>gnl|CDD|173659 cd05122, PKc_STE, Catalytic domain of STE family Protein Kinases.
Protein Kinases (PKs), STE family, catalytic (c) domain.
PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on
protein substrates. The STE family is part of a larger
superfamily that includes the catalytic domains of other
protein serine/threonine kinases (STKs), protein tyrosine
kinases (PTKs), RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase (PI3K). This family is composed of STKs, and
some dual-specificity PKs that phosphorylate both
threonine and tyrosine residues of target proteins. Most
members are kinases involved in mitogen-activated protein
kinase (MAPK) signaling cascades, acting as MAPK kinases
(MAPKKs), MAPK kinase kinases (MAPKKKs), or MAPK kinase
kinase kinases (MAP4Ks). The MAPK signaling pathways are
important mediators of cellular responses to
extracellular signals. The pathways involve a triple
kinase core cascade comprising of the MAPK, which is
phosphorylated and activated by a MAPKK, which itself is
phosphorylated and activated by a MAPKKK. Each MAPK
cascade is activated either by a small GTP-binding
protein or by an adaptor protein, which transmits the
signal either directly to a MAPKKK to start the triple
kinase core cascade or indirectly through a mediator
kinase, a MAP4K. Other STE family members include
p21-activated kinases (PAKs) and class III myosins, among
others. PAKs are Rho family GTPase-regulated kinases that
serve as important mediators in the function of Cdc42
(cell division cycle 42) and Rac. Class III myosins are
motor proteins containing an N-terminal kinase catalytic
domain and a C-terminal actin-binding domain, which can
phosphorylate several cytoskeletal proteins, conventional
myosin regulatory light chains, as well as
autophosphorylate the C-terminal motor domain. They play
an important role in maintaining the structural integrity
of photoreceptor cell microvilli.

>gnl|CDD|173660 cd05123, STKc_AGC, Catalytic domain of AGC family Protein
Serine/Threonine Kinases. Serine/Threonine Kinases
(STKs), AGC (Protein Kinases A, G and C) family,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The AGC family is part of
a larger superfamily that includes the catalytic domains
of other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and Phosphoinositide 3-Kinase (PI3K). Members of
this family include cAMP-dependent Protein Kinase (PKA),
cGMP-dependent Protein Kinase (PKG), Protein Kinase C
(PKC), Protein Kinase B (PKB), G protein-coupled Receptor
Kinase (GRK), Serum- and Glucocorticoid-induced Kinase
(SGK), and 70 kDa ribosomal Protein S6 Kinase (p70S6K or
S6K), among others. AGC kinases share an activation
mechanism based on the phosphorylation of up to three
sites: the activation loop (A-loop), the hydrophobic
motif (HM) and the turn motif. Phosphorylation at the
A-loop is required of most AGC kinases, which results in
a disorder-to-order transition of the A-loop. The ordered
conformation results in the access of substrates and ATP
to the active site. A subset of AGC kinases with
C-terminal extensions containing the HM also requires
phosphorylation at this site. Phosphorylation at the HM
allows the C-terminal extension to form an ordered
structure that packs into the hydrophobic pocket of the
catalytic domain, which then reconfigures the kinase into
an active bi-lobed state. In addition, growth
factor-activated AGC kinases such as PKB, p70S6K, RSK,
MSK, PKC, and SGK, require phosphorylation at the turn
motif (also called tail or zipper site), located
N-terminal to the HM at the C-terminal extension. AGC
kinases regulate many cellular processes including
division, growth, survival, metabolism, motility, and
differentiation. Many are implicated in the development
of various human diseases.

receptor-mediated proliferation, cell polarity, cell
motility, cell death and survival, and actin cytoskeleton
organization. PAK deregulation is associated with tumor
development. PAKs from higher eukaryotes are classified
into two groups (I and II), according to their
biochemical and structural features. Group I PAKs contain
a PBD (p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). Group II PAKs
contain a PBD and a catalytic domain, but lack other
motifs found in group I PAKs. Since group II PAKs do not
contain an obvious AID, they may be regulated differently
from group I PAKs. Group I PAKs interact with the SH3
containing proteins Nck, Grb2 and PIX; no such binding
has been demonstrated for group II PAKs.

cAMP-dependent proteins kinases, PKA and PRKX. The
inactive PKA holoenzyme is a heterotetramer composed of
two phosphorylated and active catalytic (C) subunits with
a dimer of regulatory (R) subunits. Activation is
achieved through the binding of the important second
messenger cAMP to the R subunits, which leads to the
dissociation of PKA into the R dimer and two active C
subunits. PKA is present ubiquitously in cells and
interacts with many different downstream targets. It
plays a role in the regulation of diverse processes such
as growth, development, memory, metabolism, gene
expression, immunity, and lipolysis.

The cGK subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. Mammals have two cGK isoforms from different
genes, cGKI and cGKII. cGKI exists as two splice
variants, cGKI-alpha and cGKI-beta. cGK consists of an
N-terminal regulatory domain containing a dimerization
and an autoinhibitory pseudosubstrate region, two
cGMP-binding domains, and a C-terminal catalytic domain.
Binding of cGMP to both binding sites releases the
inhibition of the catalytic center by the pseudosubstrate
region, allowing autophosphorylation and activation of
the kinase. cGKI is a soluble protein expressed in all
smooth muscles, platelets, cerebellum, and kidney. It is
also expressed at lower concentrations in other tissues.
cGKII is a membrane-bound protein that is most abundantly
expressed in the intestine. It is also present in the
brain nuclei, adrenal cortex, kidney, lung, and prostate.
cGKI is involved in the regulation of smooth muscle tone,
smooth cell proliferation, and platelet activation. cGKII
plays a role in the regulation of secretion, such as
renin secretion by the kidney and aldosterone secretion
by the adrenal. It also regulates bone growth and the
circadian rhythm.

It functions as a coactivator of the androgen receptor in
prostate cells. MRK, also called Intestinal Cell Kinase

in the ovary and uterus. A missense mutation in MRK
causes endocrine-cerebro-osteodysplasia (ECO), suggesting
that this protein plays an important role in the

in regulating cell cycle and cell fate. Ime2p is a
meiosis-specific kinase that is important during meiotic
initiation and during the later stages of meiosis. Mde3
functions downstream of the transcription factor Mei-4
which is essential for meiotic prophase I.

Serine/Threonine Kinases. Serine/threonine kinases
(STKs), mitogen-activated protein kinase (MAPK) kinase
kinase kinase 3 (MAPKKKK3 or MAP4K3)-like subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAP4K3-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein tyrosine
kinases, RIO kinases, aminoglycoside phosphotransferase,
choline kinase, and phosphoinositide 3-kinase. This
subfamily includes MAP4K3, MAP4K1, MAP4K2, MAP4K5, and
related proteins. Vertebrate members contain an
N-terminal catalytic domain and a C-terminal citron
homology (CNH) regulatory domain, similar to MAP4K4/6.
MAP4Ks are involved in some MAPK signaling pathways that
are important in mediating cellular responses to
extracellular signals by activating a MAPK kinase kinase
(MAPKKK or MAP3K or MKKK). Each MAPK cascade is activated
either by a small GTP-binding protein or by an adaptor
protein, which transmits the signal either directly to a
MAP3K to start the triple kinase core cascade or
indirectly through a mediator kinase, a MAP4K. MAP4K1,
also called haematopoietic progenitor kinase 1 (HPK1), is
a hematopoietic-specific STK involved in many cellular
signaling cascades including MAPK, antigen receptor,
apoptosis, growth factor, and cytokine signaling. It
participates in the regulation of T cell receptor
signaling and T cell-mediated immune responses. MAP4K2
was referred to as germinal center (GC) kinase because of
its preferred location in GC B cells. MAP4K3 plays a role
in the nutrient-responsive pathway of mTOR (mammalian
target of rapamycin) signaling. It is required in the
activation of S6 kinase by amino acids and for the
phosphorylation of the mTOR-regulated inhibitor of
eukaryotic initiation factor 4E. MAP4K5, also called
germinal center kinase-related enzyme (GCKR), has been
shown to activate the MAPK c-Jun N-terminal kinase (JNK).

subfamily is part of a larger superfamily that includes
the catalytic domains of other protein serine/threonine
kinases, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. The mitogen-activated protein
(MAP) kinase signaling pathways are important mediators
of cellular responses to extracellular signals. The
pathways involve a triple kinase core cascade comprising
of the MAP kinase (MAPK), which is phosphorylated and
activated by a MAPK kinase (MAPKK or MKK), which itself
is phosphorylated and activated by a MAPK kinase kinase
(MAPKKK or MKKK). Members of this group include MAPKKs
from plants, kinetoplastids, alveolates, and mycetozoa.
The MAPKK, LmxPK4, from Leishmania mexicana, is important
in differentiation and virulence. Dictyostelium
discoideum MEK1 is required for proper chemotaxis. MEK1
null mutants display severe defects in cell polarization
and directional movement. Plants contain multiple MAPKKs
like other eukaryotes. The Arabidopsis genome encodes for
10 MAPKKs while poplar and rice contain 13 MAPKKs each.
The functions of these proteins have not been fully
elucidated. There is evidence to suggest that MAPK
cascades are involved in plant stress responses. In
Arabidopsis, MKK3 plays a role in pathogen signaling,
MKK2 is involved in cold and salt stress signaling,
MKK4/MKK5 participates in innate immunity, and MKK7
regulates basal and systemic acquired resistance.

gamma-phosphoryl group from ATP to serine/threonine

of a family of 11 different Neks (Nek1-11) that are
involved in cell cycle control. The Nek family is part of
a larger superfamily that includes the catalytic domains
of other protein STKs, protein tyrosine kinases, RIO

includes Aspergillus nidulans NIMA kinase, the founding
member of the Nek family, which was identified in a
screen for cell cycle mutants prevented from entering
mitosis. NIMA is essential for mitotic entry and
progression through mitosis, and its degradation is
essential for mitotic exit. NIMA is involved in nuclear
membrane fission. Vertebrate Nek2 is a cell
cycle-regulated STK, localized in centrosomes and
kinetochores, that regulates centrosome splitting at the
G2/M phase. It also interacts with other mitotic kinases
such as Polo-like kinase 1 and may play a role in spindle
checkpoint. An increase in the expression of the human
NEK2 gene is strongly associated with the progression of
non-Hodgkin lymphoma.

including growth factor receptor-mediated proliferation,
cell polarity, cell motility, cell death and survival,
and actin cytoskeleton organization. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
Group I PAKs, also called conventional PAKs, include
PAK1, PAK2, and PAK3. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). They interact
with the SH3 domain containing proteins Nck, Grb2 and
PIX. Binding of group I PAKs to activated GTPases leads
to conformational changes that destabilize the AID,
allowing autophosphorylation and full activation of the
kinase domain. Known group I PAK substrates include MLCK,
Bad, Raf, MEK1, LIMK, Merlin, Vimentin, Myc, Stat5a, and
Aurora A, among others.

regulated by their cognate cyclins. Together, they are
involved in the control of cell-cycle progression,
transcription, and neuronal function. CDKs are partly
regulated by their subcellular localization, which
defines substrate phosphorylation and the resulting
specific function. CDK1, CDK2, CDK4, and CDK6 have
well-defined functions in the cell cycle, such as the
regulation of the early G1 phase by CDK4 or CDK6, the
G1/S phase transition by CDK2, or the entry of mitosis by
CDK1. They also exhibit overlapping cyclin specificity
and functions in certain conditions. Knockout mice with a
single CDK deleted remain viable with specific
phenotypes, showing that some CDKs can compensate for
each other. For example, CDK4 can compensate for the loss
of CDK6, however, double knockout mice with both CDK4 and
CDK6 deleted die in utero. CDK8 and CDK9 are mainly
involved in transcription while CDK5 is implicated in
neuronal function. CDK7 plays essential roles in both the
cell cycle as a CDK-Activating Kinase (CAK) and in
transcription as a component of the general transcription
factor TFIIH.

proteins with an N-terminal kinase catalytic domain and a
C-terminal actin-binding motor domain. Class III myosins
are present in the photoreceptors of invertebrates and
vertebrates and in the auditory hair cells of mammals.
The kinase domain of myosin III can phosphorylate several
cytoskeletal proteins, conventional myosin regulatory
light chains, and can autophosphorylate the C-terminal
motor domain. Myosin III may play an important role in
maintaining the structural integrity of photoreceptor
cell microvilli. It may also function as a cargo carrier
during light-dependent translocation, in photoreceptor
cells, of proteins such as transducin and arrestin. The
Drosophila class III myosin, called NinaC (Neither
inactivation nor afterpotential protein C), is critical
in normal adaptation and termination of photoresponse.
Vertebrates contain two isoforms of class III myosin,
IIIA and IIIB. This subfamily also includes mammalian
NIK-like embryo-specific kinase (NESK), Traf2- and
Nck-interacting kinase (TNIK), mitogen-activated protein
kinase (MAPK) kinase kinase kinase 4 (MAPKKKK4 or MAP4K4)

related proteins. Nak1 is required by fission yeast for
polarizing the tips of actin cytoskeleton and is involved
in cell growth, cell separation, cell morphology and
cell-cycle progression. Sid1 is a component in the
septation initiation network (SIN) signaling pathway, and
plays a role in cytokinesis. SPS1 plays a role in
regulating proteins required for spore wall formation.
MST4 plays a role in mitogen-activated protein kinase
(MAPK) signaling during cytoskeletal rearrangement,
morphogenesis, and apoptosis. MST3 phosphorylates the STK
NDR and may play a role in cell cycle progression and
cell morphology. STK25 may play a role in the regulation
of cell migration and polarization.

N-terminus contains an RGS (regulator of G protein
signaling) homology (RH) domain and several motifs. The
C-terminus diverges among different groups of GRKs. There
are seven types of GRKs, named GRK1 to GRK7. They are
subdivided into three main groups: visual (GRK1/7);
beta-adrenergic receptor kinases (GRK2/3); and GRK4-like
(GRK4/5/6). Expression of GRK2/3/5/6 is widespread while
GRK1/4/7 show a limited tissue distribution. The
substrate spectrum of the widely expressed GRKs partially
overlaps. GRKs play important roles in the
cardiovascular, immune, respiratory, skeletal, and
nervous systems.

into two groups (I and II), according to their
biochemical and structural features. PAK2 belongs to
group I. Group I PAKs contain a PBD (p21-binding domain)
overlapping with an AID (autoinhibitory domain), a
C-terminal catalytic domain, SH3 binding sites and a
non-classical SH3 binding site for PIX (PAK-interacting
exchange factor). PAK2 plays a role in pro-apoptotic
signaling. It is cleaved and activated by caspases
leading to morphological changes during apoptosis. PAK2
is also activated in response to a variety of stresses
including DNA damage, hyperosmolarity, serum starvation,
and contact inhibition, and may play a role in
coordinating the stress response. PAK2 also contributes
to cancer cell invasion through a mechanism distinct from
that of PAK1.

family GTPase-regulated kinases that serve as important
mediators in the function of Cdc42 (cell division cycle
42) and Rac. PAKs from higher eukaryotes are classified
into two groups (I and II), according to their
biochemical and structural features. PAK3 belongs to
group I. Group I PAKs contain a PBD (p21-binding domain)
overlapping with an AID (autoinhibitory domain), a
C-terminal catalytic domain, SH3 binding sites and a
non-classical SH3 binding site for PIX (PAK-interacting
exchange factor). PAK3 is highly expressed in the brain.
It is implicated in neuronal plasticity, synapse
formation, dendritic spine morphogenesis, cell cycle
progression, neuronal migration, and apoptosis.
Inactivating mutations in the PAK3 gene cause X-linked
non-syndromic mental retardation, the severity of which
depends on the site of the mutation.

has been regarded mainly as a cytosolic protein, recent
reports indicate that PAK1 also exists in significant
amounts in the nucleus, where it is involved in
transcription modulation and in cell cycle regulatory
events. PAK1 is also involved in transformation and
tumorigenesis. Its overexpression, hyperactivation and
increased nuclear accumulation is correlated to breast
cancer invasiveness and progression. Nuclear accumulation
is also linked to tamoxifen resistance in breast cancer
cells.

other motifs found in group I PAKs, such as an AID
(autoinhibitory domain) and SH3 binding sites. Since
group II PAKs do not contain an obvious AID, they may be
regulated differently from group I PAKs. While group I
PAKs interact with the SH3 containing proteins Nck, Grb2
and PIX, no such binding has been demonstrated for group
II PAKs. Some known substrates of group II PAKs are also
substrates of group I PAKs such as Raf, BAD, LIMK and
GEFH1. Unique group II substrates include MARK/Par-1 and
PDZ-RhoGEF. Group II PAKs play important roles in
filopodia formation, neuron extension, cytoskeletal
organization, and cell survival.

It associates with cyclin H and MAT1 and acts as a
CDK-Activating Kinase (CAK) by phosphorylating and
activating cell cycle CDKs (CDK1/2/4/6). In the brain, it
activates CDK5. CDK7 is also a component of the general
transcription factor TFIIH, which phosphorylates the

bound with unphosphorylated DNA, as present in the
pre-initiation complex. Following phosphorylation, the
CTD dissociates from the DNA which allows transcription
initiation.

and a C-terminal catalytic domain. MEKK2 and MEKK3 are
mitogen-activated protein kinase (MAPK) kinase kinases
(MAPKKKs or MKKKs or MAP3Ks), proteins that phosphorylate
and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks),
which in turn phosphorylate and activate MAPKs during
signaling cascades that are important in mediating
cellular responses to extracellular signals. MEKK2 and
MEKK3 activate MEK5 (also called MKK5), which activates
extracellular signal-regulated kinase 5 (ERK5). The ERK5
cascade plays roles in promoting cell proliferation,
differentiation, neuronal survival, and neuroprotection.
MEKK3 plays an essential role in embryonic angiogenesis
and early heart development. MEKK2 and MEKK3 can also

Serine/Threonine Kinases (STKs), G protein-coupled
Receptor Kinase (GRK) subfamily, GRK5 isoform, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The GRK subfamily is part
of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. GRKs phosphorylate
and regulate G protein-coupled receptors (GPCRs), the
largest superfamily of cell surface receptors which
regulate some part of nearly all physiological functions.
Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. GRK5 is widely expressed in many tissues.
It associates with the membrane though an N-terminal PIP2
binding domain and also binds phospholipids via its
C-terminus. GRK5 deficiency is associated with early
Alzheimer's disease in humans and mouse models. GRK5 also
plays a crucial role in the pathogenesis of sporadic
Parkinson's disease. It participates in the regulation
and desensitization of PDGFRbeta, a receptor tyrosine
kinase involved in a variety of downstream cellular
effects including cell growth, chemotaxis, apoptosis, and
angiogenesis. GRK5 also regulates Toll-like receptor 4,
which is involved in innate and adaptive immunity.

referred to as Rho-associated kinase or simply as Rho
kinase. It contains an N-terminal extension, a catalytic
kinase domain, and a long C-terminal extension, which
contains a coiled-coil region encompassing a Rho-binding
domain (RBD) and a pleckstrin homology (PH) domain. ROCK
is auto-inhibited by the RBD and PH domain interacting
with the catalytic domain. It is activated via
interaction with Rho GTPases and is involved in many
cellular functions including contraction, adhesion,
migration, motility, proliferation, and apoptosis. The
ROCK subfamily consists of two isoforms, ROCK1 and ROCK2,
which may be functionally redundant in some systems, but
exhibit different tissue distributions. Both isoforms are
ubiquitously expressed in most tissues, but ROCK2 is more
prominent in brain and skeletal muscle while ROCK1 is
more pronounced in the liver, testes, and kidney. Studies
in knockout mice result in different phenotypes,
suggesting that the two isoforms do not compensate for
each other during embryonic development.

N-terminal kinase domain (NTD) from the AGC family and a
C-terminal kinase domain (CTD) from the CAMK family,
similar to 90 kDa ribosomal protein S6 kinases (RSKs).
MSKs are activated by two major signaling cascades, the
Ras-MAPK and p38 stress kinase pathways, in response to
various stimuli such as growth factors, hormones,
neurotransmitters, cellular stress, and pro-inflammatory
cytokines. This triggers phosphorylation in the
activation loop (A-loop) of the CTD of MSK. The active
CTD phosphorylates the hydrophobic motif (HM) in the
C-terminal extension of NTD, which facilitates the
phosphorylation of the A-loop and activates the NTD,
which in turn phosphorylates downstream targets. MSKs are
predominantly nuclear proteins. They are widely expressed
in many tissues including heart, brain, lung, liver,
kidney, and pancreas. There are two isoforms of MSK,
called MSK1 and MSK2.

control responses such as phototropism, stromatal
opening, and chloroplast movement in order to optimize
the photosynthetic efficiency of plants. They are
light-activated STKs that contain an N-terminal
photosensory domain and a C-terminal catalytic domain.
The N-terminal domain contains two LOV (Light, Oxygen or

LOV domains results in autophosphorylation at multiple
sites and activation of the catalytic domain. Neurospora
crassa nrc-2 plays a role in growth and development by
controlling entry into the conidiation program.

>gnl|CDD|132963 cd06632, STKc_MEKK1_plant, Catalytic domain of the Protein
Serine/Threonine Kinase, Plant MAP/ERK kinase kinase 1.
Serine/threonine kinases (STKs), plant MAP/ERK kinase
kinase 1 (MEKK1)-like subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The plant MEKK1 subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. This subfamily is composed of
plant mitogen-activated protein kinase (MAPK) kinase
kinases (MAPKKKs or MKKKs or MAP3Ks) including
Arabidopsis thaliana MEKK1 and MAPKKK3. MEKK1 is a MAPKKK
that phosphorylates and activates MAPK kinases (MAPKKs or
MKKs or MAP2Ks), which in turn phosphorylate and activate
MAPKs during signaling cascades that are important in
mediating cellular responses to extracellular signals.
Arabidopsis thaliana MEKK1 activates MPK4, a MAPK that
regulates systemic acquired resistance. MEKK1 also
participates in the regulation of temperature-sensitive
and tissue-specific cell death.

ROCK-like proteins such as DMPK, MRCK, and CRIK, as well
as NDR and NDR-like proteins such as LATS, CBK1 and
Sid2p. ROCK and CRIK are effectors of the small GTPase
Rho, while MRCK is an effector of the small GTPase Cdc42.
NDR and NDR-like kinases contain an N-terminal regulatory

of a larger superfamily that includes the catalytic

classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
structural characteristics of their regulatory domain.
PKCs undergo three phosphorylations in order to take
mature forms. In addition, classical PKCs depend on
calcium, DAG (1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. Novel PKCs are
calcium-independent, but require DAG and PS for activity,
while atypical PKCs only require PS. PKCs phosphorylate
and modify the activities of a wide variety of cellular
proteins including receptors, enzymes, cytoskeletal
proteins, transcription factors, and other kinases. They
play a central role in signal transduction pathways that
regulate cell migration and polarity, proliferation,
differentiation, and apoptosis. Also included in this
subfamily are the PKC-like proteins, called PKNs.

Kinase, G protein-coupled Receptor Kinase 4.
Serine/Threonine Kinases (STKs), G protein-coupled
Receptor Kinase (GRK) subfamily, GRK4 isoform, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The GRK subfamily is part
of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. GRKs phosphorylate
and regulate G protein-coupled receptors (GPCRs), the
largest superfamily of cell surface receptors which
regulate some part of nearly all physiological functions.
Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. GRK4 has a limited tissue distribution. It
is mainly found in the testis, but is also present in the
cerebellum and kidney. It is expressed as multiple splice
variants with different domain architectures. It is
post-translationally palmitoylated and localized in the
membrane. GRK4 polymorphisms are associated with
hypertension and salt sensitivity, as they cause
hyperphosphorylation, desensitization, and
internalization of the dopamine 1 (D1) receptor while
increasing the expression of the angiotensin II type 1
receptor. GRK4 plays a crucial role in the D1 receptor
regulation of sodium excretion and blood pressure.

mitogen-activated protein (MAP) kinase signaling pathways
are important mediators of cellular responses to
extracellular signals. The pathways involve a triple
kinase core cascade comprising of the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK), which itself is phosphorylated and
activated by a MAPK kinase kinase (MAPKKK or MKKK).
Members of this group include the MAPKKs Pek1/Skh1 from
Schizosaccharomyces pombe and MKK2 from Saccharomyces
cerevisiae, and related proteins. Both fission yeast Pek1
and baker's yeast MKK2 are components of the cell
integrity MAPK pathway. In fission yeast, Pek1
phosphorylates and activates the MAPK Pmk1/Spm1 and is
regulated by the MAPKKK Mkh1. In baker's yeast, the
pathway involves the MAPK Slt2, the MAPKKs MKK1 and MKK2,
and the MAPKKK Bck1. The cell integrity MAPK cascade is
activated by multiple stress conditions, and is essential
in cell wall construction, morphogenesis, cytokinesis,
and ion homeostasis.

family is part of a larger superfamily that includes the
catalytic domains of protein serine/threonine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
They can be classified into receptor and non-receptor tyr
kinases. PTKs play important roles in many cellular
processes including, lymphocyte activation, epithelium
growth and maintenance, metabolism control, organogenesis
regulation, survival, proliferation, differentiation,
migration, adhesion, motility, and morphogenesis.
Receptor tyr kinases (RTKs) are integral membrane
proteins which contain an extracellular ligand-binding
region, a transmembrane segment, and an intracellular tyr
kinase domain. RTKs are usually activated through ligand
binding, which causes dimerization and
autophosphorylation of the intracellular tyr kinase
catalytic domain, leading to intracellular signaling.
Some RTKs are orphan receptors with no known ligands.
Non-receptor (or cytoplasmic) tyr kinases are distributed
in different intracellular compartments and are usually
multi-domain proteins containing a catalytic tyr kinase
domain as well as various regulatory domains such as SH3
and SH2. PTKs are usually autoinhibited and require a
mechanism for activation. In many PTKs, the
phosphorylation of tyr residues in the activation loop is
essential for optimal activity. Aberrant expression of
PTKs is associated with many development abnormalities
and cancers.

Cell division control protein 2 (Cdc2) or p34 protein
kinase, and is regulated by cyclins A, B, and E. The
CDK1/cyclin A complex controls G2 phase entry and
progression while the CDK1/cyclin B complex is critical
for G2 to M phase transition. CDK2 is regulated by cyclin
E or cyclin A. Upon activation by cyclin E, it
phosphorylates the retinoblastoma (pRb) protein which
activates E2F mediated transcription and allows cells to
move into S phase. The CDK2/cyclin A complex plays a role
in regulating DNA replication. Studies in knockout mice
revealed that CDK1 can compensate for the loss of the
cdk2 gene as it can also bind cyclin E and drive G1 to S
phase transition. CDK3 is regulated by cyclin C and it
phosphorylates pRB specifically during the G0/G1
transition. This phosphorylation is required for cells to

largest superfamily of cell surface receptors, which
regulate some part of nearly all physiological functions.
Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. GRK1, also called rhodopsin kinase, belongs
to the visual group of GRKs and is expressed in retinal
cells. It phosphorylates rhodopsin in rod cells, which
leads to termination of the phototransduction cascade.
Mutations in GRK1 are associated to a recessively

regulated by their cognate cyclins. Together, they are
involved in the control of cell-cycle progression,
transcription, and neuronal function. CDC2L1, also called
PITSLRE, exists in different isoforms which are named
using the alias CDK11(p). The CDC2L1 gene produces two
protein products, CDK11(p110) and CDK11(p58). CDC2L1 is
also represented by the caspase-processed CDK11(p46).
CDK11(p110), the major isoform, associates with cyclin L
and is expressed throughout the cell cycle. It is
involved in RNA processing and the regulation of
transcription. CDK11(p58) associates with cyclin D3 and
is expressed during the G2/M phase of the cell cycle. It
plays roles in spindle morphogenesis, centrosome
maturation, sister chromatid cohesion, and the completion
of mitosis. CDK11(p46) is formed from the larger isoforms
by caspases during TNFalpha- and Fas-induced apoptosis.
It functions as a downstream effector kinase in apoptotic
signaling pathways and interacts with eukaryotic
initiation factor 3f (eIF3f), p21-activated kinase
(PAK1), and Ran-binding protein (RanBPM).

dystrophy 1 (DM1), an inherited multisystemic disorder
with symptoms that include muscle hyperexcitability,
progressive muscle weakness and wasting, cataract
development, testicular atrophy, and cardiac conduction
defects. The genetic basis for DM1 is the mutational
expansion of a CTG repeat in the 3'-UTR of DMPK. DMPK is
expressed in skeletal and cardiac muscles, and in central
nervous tissues. The functional role of DMPK is not fully
understood. It may play a role in the signal transduction

of a family of 11 different Neks (Nek1-11) that are
involved in cell cycle control. The Nek family is part of
a larger superfamily that includes the catalytic domains
of other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. Nek7 is required
for mitotic spindle formation and cytokinesis. It is
enriched in the centrosome and is critical for
microtubule nucleation. Nek7 is activated by Nek9 during
mitosis, and may regulate the p70 ribosomal S6 kinase.

N-terminal kinase domain (NTD) from the AGC family and a
C-terminal kinase domain (CTD) from the CAMK family,
similar to 90 kDa ribosomal protein S6 kinases (RSKs).
MSKs are activated by two major signaling cascades, the
Ras-MAPK and p38 stress kinase pathways, which trigger
phosphorylation in the activation loop (A-loop) of the
CTD of MSK. The active CTD phosphorylates the hydrophobic
motif (HM) of NTD, which facilitates the phosphorylation
of the A-loop and activates the NTD, which in turn
phosphorylates downstream targets. MSK2 and MSK1 play
nonredundant roles in activating histone H3 kinases,
which play pivotal roles in compaction of the chromatin
fiber. MSK2 is the required H3 kinase in response to
stress stimuli and activation of the p38 MAPK pathway.
MSK2 also plays a role in the pathogenesis of psoriasis.

groups (classical, atypical, and novel) depending on
their mode of activation and the structural
characteristics of their regulatory domain. aPKCs only
require phosphatidylserine (PS) for activation. There are
two aPKC isoforms, zeta and iota. PKC-iota is directly
implicated in carcinogenesis. It is critical to oncogenic
signaling mediated by Ras and Bcr-Abl. The PKC-iota gene
is the target of tumor-specific gene amplification in
many human cancers, and has been identified as a human
oncogene. In addition to its role in transformed growth,
PKC-iota also promotes invasion, chemoresistance, and
tumor cell survival. Expression profiling of PKC-iota is
a prognostic marker of poor clinical outcome in several
human cancers. PKC-iota also plays a role in establishing
cell polarity, and has critical embryonic functions.

protein 2 (Cdc2) or p34 protein kinase, and is regulated
by cyclins A, B, and E. The CDK1/cyclin A complex
controls G2 phase entry and progression. CDK1/cyclin A2
has also been implicated as an important regulator of S
phase events. The CDK1/cyclin B complex is critical for
G2 to M phase transition. It induces mitosis by
activating nuclear enzymes that regulate chromatin
condensation, nuclear membrane degradation,
mitosis-specific microtubule and cytoskeletal
reorganization. CDK1 also associates with cyclin E and
plays a role in the entry into S phase. CDK1
transcription is stable throughout the cell cycle but is
modulated in some pathological conditions. It may play a
role in regulating apoptosis under these conditions. In
breast cancer cells, HER2 can mediate apoptosis by
inactivating CDK1. Activation of CDK1 may contribute to
HIV-1 induced apoptosis and neuronal apoptosis in
neurodegenerative diseases.

belong to a large family of STKs that are regulated by
their cognate cyclins. Together, they are involved in the
control of cell-cycle progression, transcription, and
neuronal function. CDK4 and CDK6 partner with D-type
cyclins to regulate the early G1 phase of the cell cycle.
They are the first kinase activated by mitogenic signals
to release cells from the G0 arrested state. CDK4 and
CDK6 are both expressed ubiquitously, associate with all
three D cyclins (D1, D2 and D3), and phosphorylate the
retinoblastoma (pRb) protein. They are also regulated by
the INK4 family of inhibitors which associate with either
the CDK alone or the CDK/cyclin complex. CDK4 and CDK6
show differences in subcellular localization, sensitivity
to some inhibitors, timing in activation, tumor
selectivity, and possibly substrate profiles. Although
CDK4 and CDK6 seem to show some redundancy, they also
have discrete, nonoverlapping functions. CDK6 plays an
important role in cell differentiation.

associated with early onset epilepsy and severe mental
retardation [X-linked infantile spasm syndrome (ISSX) or
West syndrome]. In addition, CDKL5 mutations also
sometimes cause a phenotype similar to Rett syndrome
(RTT), a progressive neurodevelopmental disorder. These
pathogenic mutations are located in the N-terminal
portion of the protein within the kinase domain.

Serine/Threonine Kinases (STKs), Serum- and
Glucocorticoid-induced Kinase (SGK) subfamily, SGK3
isoform, catalytic (c) domain. STKs catalyze the transfer
of the gamma-phosphoryl group from ATP to

the catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. There are three isoforms of SGK, named SGK1,
SGK2, and SGK3 (also called cytokine-independent survival
kinase CISK). SGK3 is expressed in most tissues and is
most abundant in the embryo and adult heart and spleen.
It was originally discovered in a screen for
antiapoptotic genes. It phosphorylates and inhibits the
proapoptotic proteins, Bad and FKHRL1. SGK3 also
regulates many transporters, ion channels, and receptors.
It plays a critical role in hair follicle morphogenesis
and hair cycling.

either by a small GTP-binding protein or by an adaptor
protein, which transmits the signal either directly to a
MAP3K to start the triple kinase core cascade or
indirectly through a mediator kinase, a MAP4K. MAP4K4 is
also called Nck Interacting kinase (NIK). It facilitates
the activation of the MAPKs, extracellular
signal-regulated kinase (ERK) 1, ERK2, and c-Jun
N-terminal kinase (JNK), by phosphorylating and
activating MEKK1. MAP4K4 plays a role in tumor necrosis
factor (TNF) alpha-induced insulin resistance. MAP4K4
silencing in skeletal muscle cells from type II diabetic
patients restores insulin-mediated glucose uptake.
MAP4K4, through JNK, also plays a broad role in cell
motility, which impacts inflammation, homeostasis, as
well as the invasion and spread of cancer. MAP4K4 is
found to be highly expressed in most tumor cell lines
relative to normal tissue. MAP4K6 (also called MINK for
Misshapen/NIKs-related kinase) is activated after Ras
induction and mediates activation of p38 MAPK. MAP4K6
plays a role in cell cycle arrest, cytoskeleton
organization, cell adhesion, and cell motility.

of STKs that are regulated by their cognate cyclins.
Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK2
is regulated by cyclin E or cyclin A. Upon activation by
cyclin E, it phosphorylates the retinoblastoma (pRb)
protein which activates E2F mediated transcription and
allows cells to move into S phase. The CDK2/cyclin A
complex plays a role in regulating DNA replication. CDK2,
together with CDK4, also regulates embryonic cell
proliferation. Despite these important roles, mice
deleted for the cdk2 gene are viable and normal except
for being sterile. This may be due to compensation
provided by CDK1 (also called Cdc2), which can also bind
cyclin E and drive the G1 to S phase transition. CDK3 is
regulated by cyclin C and it phosphorylates pRB
specifically during the G0/G1 transition. This
phosphorylation is required for cells to exit G0
efficiently and enter the G1 phase.

Serine/Threonine Kinase, Protein Kinase B alpha.
Serine/Threonine Kinases (STKs), Protein Kinase B (PKB)
or Akt subfamily, alpha (or Akt1) isoform, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The PKB subfamily is part
of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. There are three
PKB isoforms from different genes, PKB-alpha (or Akt1),
PKB-beta (or Akt2), and PKB-gamma (or Akt3). PKB contains
an N-terminal pleckstrin homology (PH) domain and a
C-terminal catalytic domain. PKB-alpha is predominantly
expressed in endothelial cells. It is critical for the
regulation of angiogenesis and the maintenance of
vascular integrity. It also plays a role in adipocyte
differentiation. Mice deficient in PKB-alpha exhibit
perinatal morbidity, growth retardation, reduction in
body weight accompanied by reduced sizes of multiple
organs, and enhanced apoptosis in some cell types.
PKB-alpha activity has been reported to be frequently
elevated in breast and prostate cancers. In some cancer
cells, PKB-alpha may act as a suppressor of metastasis.

the transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The nPKC
subfamily is part of a larger superfamily that includes

(classical, atypical, and novel) depending on their mode
of activation and the structural characteristics of their
regulatory domain. nPKCs are calcium-independent, but
require DAG (1,2-diacylglycerol) and phosphatidylserine
(PS) for activity. There are four nPKC isoforms, delta,
epsilon, eta, and theta. PKC-eta is predominantly
expressed in squamous epithelia, where it plays a crucial
role in the signaling of cell-type specific
differentiation. It is also expressed in pro-B cells and
early-stage thymocytes, and acts as a key regulator in
early B-cell development. PKC-eta increases glioblastoma
multiforme (GBM) proliferation and resistance to
radiation, and is being developed as a therapeutic target
for the management of GBM.

gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The ASK subfamily is part
of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,

are mitogen-activated protein kinase (MAPK) kinase
kinases (MAPKKKs or MKKKs or MAP3Ks) and include ASK1,
ASK2, and MAPKKK15. MAPKKKs phosphorylate and activate
MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn
phosphorylate and activate MAPKs during signaling
cascades that are important in mediating cellular
responses to extracellular signals. ASK1 (also called
MAPKKK5) functions in the c-Jun N-terminal kinase (JNK)
and p38 MAPK signaling pathways by directly activating
their respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. It
plays important roles in cytokine and stress responses,
as well as in reactive oxygen species (ROS)-mediated
cellular responses. ASK1 is implicated in various
diseases mediated by oxidative stress including inschemic
heart disease, hypertension, vessel injury, brain
ischemia, Fanconi anemia, asthma, and pulmonary edema,
among others. ASK2 (also called MAPKKK6) functions only
in a heteromeric complex with ASK1, and can activate ASK1
by direct phosphorylation. The function of MAPKKK15 is
still unknown.

SH2) N-terminal to the catalytic tyr kinase domain.
Unlike Src kinases, most Tec subfamily members (except
Rlk) also contain an N-terminal pleckstrin homology (PH)
domain, which binds the products of PI3K and allows
membrane recruitment and activation. In addition, some
members contain the Tec homology (TH) domain, which
contains proline-rich and zinc-binding regions. Tec
kinases form the second largest subfamily of nRTKs and
are expressed mainly by haematopoietic cells, although
Tec and Bmx are also found in endothelial cells. B-cells
express Btk and Tec, while T-cells express Itk, Txk, and
Tec. Collectively, Tec kinases are expressed in a variety
of myeloid cells such as mast cells, platelets,
macrophages, and dendritic cells. Each Tec kinase shows a
distinct cell-type pattern of expression. The function of
Tec kinases in lymphoid cells have been studied
extensively. They play important roles in the
development, differentiation, maturation, regulation,
survival, and function of B-cells and T-cells. Mutations
in Btk cause the severe B-cell immunodeficiency, X-linked
agammaglobulinaemia (XLA).

(Ig)-like domain found in titin-like proteins. Titin
(also called connectin) is a fibrous sarcomeric protein
specifically found in vertebrate striated muscle. Titin
is gigantic, depending on isoform composition it ranges
from 2970 to 3700 kDa, and is of a length that spans half
a sarcomere. Titin largely consists of multiple repeats
of Ig-like and fibronectin type 3 (FN-III)-like domains.
Titin connects the ends of myosin thick filaments to Z
disks and extends along the thick filament to the H zone.
It appears to function similarly to an elastic band,
keeping the myosin filaments centered in the sarcomere
during muscle contraction or stretching. Within the
sarcomere, titin is also attached to or is associated
with myosin binding protein C (MyBP-C). MyBP-C appears to
contribute to the generation of passive tension by titin,
and similar to titin has repeated Ig-like and FN-III
domains. Also included in this group are worm twitchin
and insect projectin, thick filament proteins of
invertebrate muscle, which also have repeated Ig-like and
FN-III domains.

NDR kinase requires phosphorylation at two sites, the
activation loop (A-loop) and the hydrophobic motif (HM),
for activity. Higher eukaryotes contain two NDR isoforms,
NDR1 and NDR2. Both isoforms play a role in proper
centrosome duplication. NDR1 is highly expressed in
thymus, muscle, lung and spleen. It is not an essential
protein because mice deficient of NDR1 remain viable and
fertile. However, these mice develop T-cell lymphomas and
appear to be hypersenstive to carcinogenic treatment.
NDR1 appears to act as a tumor suppressor. NDR1 is also

regulated by their cognate cyclins. Together, they are
involved in the control of cell-cycle progression,
transcription, and neuronal function. CDK5 is unusual in
that it is regulated by non-cyclin proteins, p35 and p39.
It is highly expressed in the nervous system and is
critical in normal neural development and function. It
plays a role in neuronal migration and differentiation,
and is also important in synaptic plasticity and
learning. CDK5 also participates in protecting against

3-kinase. The MEKK3-like subfamily is composed of MEKK3,
MEKK2, and related proteins, all containing an N-terminal
PB1 domain, which mediates oligomerization, and a
C-terminal catalytic domain. MEKK2 and MEKK3 are
mitogen-activated protein kinase (MAPK) kinase kinases
(MAPKKKs or MKKKs or MAP3Ks), proteins that phosphorylate
and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks),
which in turn phosphorylate and activate MAPKs during
signaling cascades that are important in mediating
cellular responses to extracellular signals. MEKK2 and
MEKK3 activate MEK5 (also called MKK5), which activates
extracellular signal-regulated kinase 5 (ERK5). The ERK5
cascade plays roles in promoting cell proliferation,
differentiation, neuronal survival, and neuroprotection.
MEKK3 plays an essential role in embryonic angiogenesis
and early heart development. MEKK2 and MEKK3 can also
activate the MAPKs, c-Jun N-terminal kinase (JNK) and
p38, through their respective MAPKKs.

is expressed in T-cells and mast cells, and is important
in their development and differentiation. Of the three
Tec kinases expressed in T-cells, Itk plays the
predominant role in T-cell receptor (TCR) signaling. It
is activated by phosphorylation upon TCR crosslinking and
is involved in the pathway resulting in phospholipase

Kinases, Bruton's tyrosine kinase and Bone marrow kinase
on the X chromosome. Protein Tyrosine Kinase (PTK)
family; Bruton's tyrosine kinase (Btk) and Bone marrow
kinase on the X chromosome (Bmx); catalytic (c) domain.
The PTKc family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Btk and
Bmx (also named Etk) are members of the Tec subfamily of
proteins, which are cytoplasmic (or nonreceptor) tyr
kinases with similarity to Src kinases in that they
contain Src homology protein interaction domains (SH3,
SH2) N-terminal to the catalytic tyr kinase domain.
Unlike Src kinases, most Tec subfamily members (except
Rlk) also contain an N-terminal pleckstrin homology (PH)
domain, which binds the products of PI3K and allows
membrane recruitment and activation. In addition, Btk
contains the Tec homology (TH) domain with proline-rich
and zinc-binding regions. Tec kinases are expressed
mainly by haematopoietic cells. Btk is expressed in
B-cells, and a variety of myeloid cells including mast
cells, platelets, neutrophils, and dendrictic cells. It
interacts with a variety of partners, from cytosolic
proteins to nuclear transcription factors, suggesting a
diversity of functions. Stimulation of a diverse array of
cell surface receptors, including antigen engagement of
the B-cell receptor (BCR), leads to PH-mediated membrane
translocation of Btk and subsequent phosphorylation by
Src kinase and activation. Btk plays an important role in
the life cycle of B-cells including their development,
differentiation, proliferation, survival, and apoptosis.
Mutations in Btk cause the primary immunodeficiency
disease, X-linked agammaglobulinaemia (XLA) in humans.
Bmx is primarily expressed in bone marrow and the
arterial endothelium, and plays an important role in
ischemia-induced angiogenesis. It facilitates arterial
growth, capillary formation, vessel maturation, and bone
marrow-derived endothelial progenitor cell mobilization.

RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. PKCs are
classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
structural characteristics of their regulatory domain.
PKCs undergo three phosphorylations in order to take
mature forms. In addition, cPKCs depend on calcium, DAG
(1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. There are four
cPKC isoforms, named alpha, betaI, betaII, and gamma.
PKC-alpha is expressed in many tissues and is associated
with cell proliferation, apoptosis, and cell motility. It
plays a role in the signaling of the growth factors PDGF,
VEGF, EGF, and FGF. Abnormal levels of PKC-alpha have
been detected in many transformed cell lines and several
human tumors. In addition, PKC-alpha is required for HER2
dependent breast cancer invasion.

subfamily, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
class III myosin subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. Class III myosins are motor
proteins containing an N-terminal kinase catalytic domain
and a C-terminal actin-binding domain. Class III myosins
may play an important role in maintaining the structural
integrity of photoreceptor cell microvilli. In
photoreceptor cells, they may also function as cargo
carriers during light-dependent translocation of proteins
such as transducin and arrestin. Class IIIA myosin is
highly expressed in retina and in inner ear hair cells.
It is localized to the distal ends of actin-bundled
structures. Mutations in human myosin IIIA are
responsible for progressive nonsyndromic hearing loss.
Human myosin IIIA possesses ATPase and kinase activities,
and the ability to move actin filaments in a motility
assay. It may function as a cellular transporter capable
of moving along actin bundles in sensory cells.

Serine/Threonine Kinases (STKs), Extracellular
signal-Regulated Kinase 5 (ERK5) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The ERK5 subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. MAPKs are
important mediators of cellular responses to
extracellular signals. ERK5, also called Big MAPK1 (BMK1)
or MAPK7, has a unique C-terminal extension, making it
approximately twice as big as other MAPKs. This extension
contains transcriptional activation capability which is
inhibited by the N-terminal half. ERK5 is activated in
response to growth factors and stress by a cascade that
leads to its phosphorylation by the MAP2K MEK5, which in
turn is regulated by the MAP3Ks MEKK2 and MEKK3.
Activated ERK5 phosphorylates its targets including
myocyte enhancer factor 2 (MEF2), Sap1a, c-Myc, and RSK.
It plays a role in EGF-induced cell proliferation during
the G1/S phase transition. Studies on knockout mice
revealed that ERK5 is essential for cardiovascular
development and plays an important role in angiogenesis.
It is also critical for neural differentiation and
survival. The ERK5 pathway has been implicated in the
pathogenesis of many diseases including cancer, cardiac
hypertrophy, and atherosclerosis.

aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. This subfamily is composed of
the mitogen-activated protein kinases (MAPKs) ERK1, ERK2,
baker's yeast Fus3, and similar proteins. MAPK pathways
are important mediators of cellular responses to
extracellular signals. ERK1/2 activation is
preferentially by mitogenic factors, differentiation
stimuli, and cytokines, through a kinase cascade
involving the MAPK kinases MEK1/2 and a MAPK kinase
kinase from the Raf family. ERK1/2 have numerous
substrates, many of which are nuclear and participate in
transcriptional regulation of many cellular processes.
They regulate cell growth, cell proliferation, and cell
cycle progression from G1 to S phase. Although the
distinct roles of ERK1 and ERK2 have not been fully
determined, it is known that ERK2 can maintain most
functions in the absence of ERK1, and that the deletion
of ERK2 is embryonically lethal. The MAPK, Fus3,
regulates yeast mating processes including
mating-specific gene expression, G1 arrest, mating
projection, and cell fusion.

classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
structural characteristics of their regulatory domain.
PKCs undergo three phosphorylations in order to take
mature forms. In addition, cPKCs depend on calcium, DAG
(1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. There are four
cPKC isoforms, named alpha, betaI, betaII, and gamma. The
PKC beta isoforms (I and II), generated by alternative
splicing of a single gene, are preferentially activated
by hyperglycemia-induced DAG in retinal tissues. This is
implicated in diabetic microangiopathy such as ischemia,
neovascularization, and abnormal vasodilator function.
PKC-beta also plays an important role in VEGF signaling.
In addition, glucose regulates proliferation in retinal
endothelial cells via PKC-betaI. PKC-beta is also being
explored as a therapeutic target in cancer. It
contributes to tumor formation and is involved in the
tumor host mechanisms of inflammation and angiogenesis.

mitogen-activated protein (MAP) kinase signaling pathways
are important mediators of cellular responses to
extracellular signals. The pathways involve a triple
kinase core cascade comprising the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK), which itself is phosphorylated and
activated by a MAPK kinase kinase (MAPKKK or MKKK). MEK2
is a dual-specificity PK that phosphorylates and
activates the downstream targets, extracellular
signal-regulated kinase (ERK) 1 and ERK2, on specific
threonine and tyrosine residues. The ERK cascade starts
with extracellular signals including growth factors,
hormones, and neurotransmitters, which act through
receptors and ion channels to initiate intracellular
signaling that leads to the activation at the MAPKKK
(Raf-1 or MOS) level, which leads to the transmission of
signals to MEK2, and finally to ERK1/2. The ERK cascade
plays an important role in cell proliferation,
differentiation, oncogenic transformation, and cell cycle
control, as well as in apoptosis and cell survival under
certain conditions. Gain-of-function mutations in genes
encoding ERK cascade proteins, including MEK2, cause
cardiofaciocutaneous (CFC) syndrome, a condition leading
to multiple congenital anomalies and mental retardation
in patients.

dual-specificity MAP kinase kinases. Protein kinases
(PKs), MAP kinase kinase (MAPKK) subfamily, fungal
Byr1-like proteins, catalytic (c) domain. PKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine or tyrosine residues on protein
substrates. The MAPKK subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein serine/threonine kinases, protein tyrosine
kinases, RIO kinases, aminoglycoside phosphotransferase,
choline kinase, and phosphoinositide 3-kinase. The
mitogen-activated protein (MAP) kinase signaling pathways
are important mediators of cellular responses to
extracellular signals. The pathways involve a triple
kinase core cascade comprising of the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK), which itself is phosphorylated and
activated by a MAPK kinase kinase (MAPKKK or MKKK).
Members of this group include the MAPKKs Byr1 from
Schizosaccharomyces pombe, FUZ7 from Ustilago maydis, and
related proteins. Byr1 phosphorylates its downstream
target, the MAPK Spk1, and is regulated by the MAPKKK
Byr2. The Spk1 cascade is pheromone-responsive and is
essential for sporulation and sexual differentiation in
fission yeast. FUZ7 phosphorylates and activates its
target, the MAPK Crk1, which is required in mating and
virulence in U. maydis.

Tyrosine Kinase, Janus kinase 1. Protein Tyrosine Kinase
(PTK) family; Janus kinase 1 (Jak1); catalytic (c) domain
(repeat 2). The PTKc family is part of a larger
superfamily that includes the catalytic domains of other
kinases such as protein serine/threonine kinases, RIO
kinases, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
Jak1 is a member of the Janus kinase (Jak) subfamily of
proteins, which are cytoplasmic (or nonreceptor) tyr
kinases containing an N-terminal FERM domain, followed by
a Src homology 2 (SH2) domain, a pseudokinase domain, and
a C-terminal tyr kinase domain. Jaks are crucial for
cytokine receptor signaling. They are activated by
autophosphorylation upon cytokine-induced receptor
aggregation, and subsequently trigger downstream
signaling events such as the phosphorylation of signal
transducers and activators of transcription (STATs). Jak1
is widely expressed in many tissues. Many cytokines are
dependent on Jak1 for signaling, including those that use
the shared receptor subunits common gamma chain (IL-2,
IL-4, IL-7, IL-9, IL-15, IL-21) and gp130 (IL-6, IL-11,
oncostatin M, G-CSF, and IFNs, among others). The many
varied interactions of Jak1 and its ubiquitous expression
suggest many biological roles. Jak1 is important in
neurological development, as well as in lymphoid
development and function. It also plays a role in the
pathophysiology of cardiac hypertrophy and heart failure.
A mutation in the ATP-binding site of Jak1 was identified
in a human uterine leiomyosarcoma cell line, resulting in
defective cytokine induction and antigen presentation,
thus allowing the tumor to evade the immune system.

Txk) are members of the Tec subfamily of proteins, which
are cytoplasmic (or nonreceptor) tyr kinases with
similarity to Src kinases in that they contain Src
homology protein interaction domains (SH3, SH2)
N-terminal to the catalytic tyr kinase domain. Unlike Src
kinases, most Tec subfamily members (except Rlk) also
contain an N-terminal pleckstrin homology (PH) domain,
which binds the products of PI3K and allows membrane
recruitment and activation. Instead of PH, Rlk contains
an N-terminal cysteine-rich region. In addition to PH,
Tec also contains the Tec homology (TH) domain with
proline-rich and zinc-binding regions. Tec kinases are
expressed mainly by haematopoietic cells. Tec is more
widely-expressed than other Tec subfamily kinases. It is
found in endothelial cells, both B- and T-cells, and a
variety of myeloid cells including mast cells, erythroid
cells, platelets, macrophages and neutrophils. Rlk is
expressed in T-cells and mast cell lines. Tec and Rlk are
both key components of T-cell receptor (TCR) signaling.
They are important in TCR-stimulated proliferation, IL-2
production and phopholipase C-gamma1 activation.

Serine/Threonine Kinases (STKs), Novel Protein Kinase C
(nPKC), theta isoform, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from

The nPKC subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PKCs are classified into three groups
(classical, atypical, and novel) depending on their mode
of activation and the structural characteristics of their
regulatory domain. nPKCs are calcium-independent, but
require DAG (1,2-diacylglycerol) and phosphatidylserine
(PS) for activity. There are four nPKC isoforms, delta,
epsilon, eta, and theta. PKC-theta is selectively
expressed in T-cells and plays an important and
non-redundant role in several aspects of T-cell biology.
Although T-cells also express other PKC isoforms,
PKC-theta is unique in that upon antigen stimulation, it
is translocated to the plasma membrane at the
immunological synapse, where it mediates signals
essential for T-cell activation. It is essential for
TCR-induced proliferation, cytokine production, T-cell
survival, and the differentiation and effector function
of T-helper (Th) cells, particularly Th2 and Th17.
PKC-theta is being developed as a therapeutic target for
Th2-mediated allergic inflammation and Th17-mediated
autoimmune diseases.

protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. GRKs phosphorylate and regulate G
protein-coupled receptors (GPCRs), the largest
superfamily of cell surface receptors which regulate some
part of nearly all physiological functions.
Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. The beta-ARK group is composed of GRK2,
GRK3, and similar proteins. GRK2 and GRK3 are both widely
expressed in many tissues, although GRK2 is present at
higher levels. They contain an N-terminal RGS homology
(RH) domain, a central catalytic domain, and C-terminal
pleckstrin homology (PH) domain that mediates PIP2 and G
protein betagamma-subunit translocation to the membrane.
GRK2 (also called beta-ARK or beta-ARK1) is important in
regulating several cardiac receptor responses. It plays a
role in cardiac development and in hypertension. Deletion
of GRK2 in mice results in embryonic lethality, caused by
hypoplasia of the ventricular myocardium. GRK2 also plays
important roles in the liver (as a regulator of portal
blood pressure), in immune cells, and in the nervous
system. Altered GRK2 expression has been reported in
several disorders including major depression,
schizophrenia, bipolar disorder, and Parkinsonism.

Kinase, MAP kinase kinase 7. Protein kinases (PKs), MAP
kinase kinase 7 (MKK7) subfamily, catalytic (c) domain.
PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on
protein substrates. The MKK7 subfamily is part of a
larger superfamily that includes the catalytic domains of
other protein serine/threonine kinases, protein tyrosine
kinases, RIO kinases, aminoglycoside phosphotransferase,
choline kinase, and phosphoinositide 3-kinase. The
mitogen-activated protein (MAP) kinase signaling pathways
are important mediators of cellular responses to
extracellular signals. The pathways involve a triple
kinase core cascade comprising the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK), which itself is phosphorylated and
activated by a MAPK kinase kinase (MAPKKK or MKKK). MKK7
is a dual-specificity PK that phosphorylates and
activates its downstream target, c-Jun N-terminal kinase
(JNK), on specific threonine and tyrosine residues.
Although MKK7 is capable of dual phosphorylation, it
prefers to phosphorylate the threonine residue of JNK.
Thus, optimal activation of JNK requires both MKK4 (not
included in this subfamily) and MKK7. MKK7 is primarily
activated by cytokines. MKK7 is essential for liver
formation during embryogenesis. It plays roles in G2/M
cell cycle arrest and cell growth. In addition, it is
involved in the control of programmed cell death, which
is crucial in oncogenesis, cancer chemoresistance, and
antagonism to TNFalpha-induced killing, through its
inhibition by Gadd45beta and the subsequent suppression
of the JNK cascade.

activity. MAPK signaling cascades are important in
mediating cellular responses to extracellular signals.
Human TAO2 is also known as prostate-derived Ste20-like
kinase (PSK) and was identified in a screen for
overexpressed RNAs in prostate cancer. TAO2 activates
both p38 and c-Jun N-terminal kinase (JNK), by
phosphorylating and activating the respective MAP/ERK
kinases (MEKs, also known as MKKs or MAPKKs), MEK3/MEK6
and MKK4/MKK7. TAO2 contains a long C-terminal extension
with autoinhibitory segments. It is activated by the
release of this inhibition and the phosphorylation of its
activation loop serine. TAO2 functions as a regulator of
actin cytoskeletal and microtubule organization. In
addition, it regulates the transforming growth
factor-activated kinase 1 (TAK1), which is a MAPKKK that
plays an essential role in the signaling pathways of
tumor necrosis factor (TNF), interleukin 1 (IL-1), and
Toll-like receptor (TLR).

TAO1 is highly expressed in the brain and may play a role
in neuronal apoptosis. TAO1 interacts with the checkpoint
proteins BubR1 and Mad2, and plays an important role in
regulating mitotic progression, which is required for
both chromosome congression and checkpoint-induced
anaphase delay. TAO1 may play a role in protecting
genomic stability.

pathways that regulate cytokine and growth factor
responses, cytoskeleton dynamics, cell proliferation,
survival, and differentiation. Lyn is expressed in B
lymphocytes and myeloid cells. It exhibits both positive
and negative regulatory roles in B cell receptor (BCR)
signaling. Lyn, as well as Fyn and Blk, promotes B cell
activation by phosphorylating ITAMs (immunoreceptor tyr

domain. The PTKc family is part of a larger superfamily
that includes the catalytic domains of other kinases such
as protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. FAK is a
cytoplasmic (or nonreceptor) tyr kinase that contains an
autophosphorylation site and a FERM domain at the
N-terminus, a central tyr kinase domain, proline-rich
regions, and a C-terminal FAT (focal adhesion targeting)
domain. FAK activity is dependent on integrin-mediated
cell adhesion, which facilitates N-terminal
autophosphorylation. Full activation is achieved by the
phosphorylation of its two adjacent A-loop tyrosines. FAK
is important in mediating signaling initiated at sites of
cell adhesions and at growth factor receptors. Through
diverse molecular interactions, FAK functions as a
biosensor or integrator to control cell motility. It is a
key regulator of cell survival, proliferation, migration
and invasion, and thus plays an important role in the
development and progression of cancer. Src binds to
autophosphorylated FAK forming the FAK-Src dual kinase
complex, which is activated in a wide variety of tumor
cells and generates signals promoting growth and
metastasis. FAK is being developed as a target for cancer
therapy.

composed of the MAPKs MPK1 from Saccharomyces cerevisiae,
Pmk1 from Schizosaccharomyces pombe, and similar
proteins. MAPKs are important mediators of cellular
responses to extracellular signals. MPK1 (also called
Slt2) and Pmk1 (also called Spm1) are stress-activated
MAPKs that regulate the cell wall integrity (CWI)
pathway, and are therefore important in the maintainance
of cell shape, cell wall construction, morphogenesis, and
ion homeostasis. MPK1 is activated in response to cell
wall stress including heat stimulation, osmotic shock, UV
irradiation, and any agents that interfere with cell wall
biogenesis such as chitin antagonists, caffeine, or
zymolase. MPK1 is regulated by the MAP2Ks Mkk1/2, which
are regulated by the MAP3K Bck1. Pmk1 is also activated
by multiple stresses including elevated temperatures,
hyper- or hypotonic stress, glucose deprivation, exposure
to cell-wall damaging compounds, and oxidative stress. It
is regulated by the MAP2K Pek1, which is regulated by the
MAP3K Mkh1.

phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PKCs are classified into three groups
(classical, atypical, and novel) depending on their mode
of activation and the structural characteristics of their
regulatory domain. nPKCs are calcium-independent, but
require DAG (1,2-diacylglycerol) and phosphatidylserine
(PS) for activity. There are four nPKC isoforms, delta,
epsilon, eta, and theta. PKC-delta plays a role in cell
cycle regulation and programmed cell death in many cell
types. It slows down cell proliferation, inducing cell
cycle arrest and enhancing cell differentiation.
PKC-delta is also involved in the regulation of
transcription as well as immune and inflammatory
responses. It plays a central role in the genotoxic
stress response that leads to DNA damaged-induced
apoptosis.

of the Janus kinase (Jak) subfamily of proteins, which
are cytoplasmic (or nonreceptor) tyr kinases containing
an N-terminal FERM domain, followed by a Src homology 2
(SH2) domain, a pseudokinase domain, and a C-terminal
catalytic tyr kinase domain. Jaks are crucial for
cytokine receptor signaling. They are activated by
autophosphorylation upon cytokine-induced receptor
aggregation, and subsequently trigger downstream
signaling events such as the phosphorylation of signal
transducers and activators of transcription (STATs). Jak2
is widely expressed in many tissues while Jak3 is
expressed only in hematopoietic cells. Jak2 is essential
for the signaling of hormone-like cytokines such as
growth hormone, erythropoietin, thrombopoietin, and
prolactin, as well as some IFNs and cytokines that signal
through the IL-3 and gp130 receptors. Jak3 binds the
shared receptor subunit common gamma chain and thus, is
essential in the signaling of cytokines that use it such
as IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21. Disruption
of Jak2 in mice results in an embryonic lethal phenotype
with multiple defects including erythropoietic and
cardiac abnormalities. It is the only Jak gene that
results in a lethal phenotype when disrupted in mice. A
mutation in the pseudokinase domain of Jak2, V617F, is
present in many myeloproliferative diseases, including
almost all patients with polycythemia vera, and 50% of
patients with essential thrombocytosis and myelofibrosis.
Jak3 is important in lymphoid development and myeloid
cell differentiation. Inactivating mutations in Jak3 have
been reported in humans with severe combined
immunodeficiency (SCID).

pathways that regulate cytokine and growth factor
responses, cytoskeleton dynamics, cell proliferation,
survival, and differentiation. Frk, also known as Rak, is
specifically expressed in liver, lung, kidney, intestine,
mammary glands, and the islets of Langerhans. Rodent
homologs were previously referred to as GTK
(gastrointestinal tyr kinase), BSK (beta-cell Src-like

reveal that Frk is not essential for viability. It plays
a role in the signaling that leads to cytokine-induced
beta-cell death in Type I diabetes. It also regulates
beta-cell number during embryogenesis and early in life.

phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to

c-Abl) is a ubiquitously-expressed cytoplasmic (or
nonreceptor) tyr kinase that contains SH3, SH2, and tyr
kinase domains in its N-terminal region, as well as
nuclear localization motifs, a putative DNA-binding
domain, and F- and G-actin binding domains in its
C-terminal tail. It also contains a short autoinhibitory
cap region in its N-terminus. Abl is normally inactive
and requires phosphorylation and myristoylation for
activation. Abl function depends on its subcellular
localization. In the cytoplasm, Abl plays a role in cell
proliferation and survival. In response to DNA damage or
oxidative stress, Abl is transported to the nucleus where
it induces apoptosis. In chronic myelogenous leukemia
(CML) patients, an aberrant translocation results in the
replacement of the first exon of Abl with the BCR
(breakpoint cluster region) gene. The resulting BCR-Abl
fusion protein is constitutively active and associates
into tetramers, resulting in a hyperactive kinase sending
a continuous signal. This leads to uncontrolled
proliferation, morphological transformation and
anti-apoptotic effects. BCR-Abl is the target of
selective inhibitors, such as imatinib (Gleevec), used in
the treatment of CML. Abl2, also known as ARG
(Abelson-related gene), is thought to play a cooperative
role with Abl in the proper development of the nervous
system. The Tel-ARG fusion protein, resulting from
reciprocal translocation between chromosomes 1 and 12, is
associated with acute myeloid leukemia (AML). The TEL
gene is a frequent fusion partner of other tyr kinase
oncogenes, including Tel/Abl, Tel/PDGFRbeta, and
Tel/Jak2, found in patients with leukemia and
myeloproliferative disorders.

family; Hematopoietic cell kinase (Hck); catalytic (c)
domain. The PTKc family is part of a larger superfamily
that includes the catalytic domains of other kinases such
as protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Hck is a
member of the Src subfamily of proteins, which are
cytoplasmic (or non-receptor) tyr kinases. Src kinases
contain an N-terminal SH4 domain with a myristoylation
site, followed by SH3 and SH2 domains, a tyr kinase
domain, and a regulatory C-terminal region containing a
conserved tyr. They are activated by autophosphorylation
at the tyr kinase domain, but are negatively regulated by
phosphorylation at the C-terminal tyr by Csk (C-terminal
Src Kinase). Src proteins are involved in signaling
pathways that regulate cytokine and growth factor
responses, cytoskeleton dynamics, cell proliferation,
survival, and differentiation. Hck is present in myeloid
and lymphoid cells that play a role in the development of
cancer. It may be important in the oncogenic signaling of
the protein Tel-Abl, which induces a chronic myelogenous
leukemia (CML)-like disease. Hck also acts as a negative
regulator of granulocyte colony-stimulating factor
(G-CSF)-induced proliferation of granulocytic precursors,
suggesting a possible role in the development of acute
myeloid leukemia (AML). In addition, Hck is essential in
regulating the degranulation of polymorphonuclear
leukocytes (PMNs). Genetic polymorphisms affect the
expression level of Hck, which affects PMN mediator
release and influences the development of chronic
obstructive pulmonary disease (COPD).

(STKs), PCTAIRE-like subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The PCTAIRE-like subfamily is part of a
larger superfamily that includes the catalytic domains of
other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline

subfamily share sequence similarity with Cyclin-Dependent
Kinases (CDKs), which belong to a large family of STKs
that are regulated by their cognate cyclins. Together,
CDKs and cyclins are involved in the control of
cell-cycle progression, transcription, and neuronal
function. The association of PCTAIRE-like proteins with
cyclins has not been widely studied, although PFTAIRE-1
has been shown to function as a CDK which is regulated by
cyclin D3 as well as the membrane-associated cyclin Y.
PCTAIRE-like proteins show unusual expression patterns
with high levels in post-mitotic tissues, suggesting that
they may be involved in regulating post-mitotic cellular
events.

T-cells and natural killer (NK) cells. It plays a
critical role in T-cell maturation, activation, and
T-cell receptor (TCR) signaling. Lck phosphorylates ITAM
(immunoreceptor tyr activation motif) sequences on
several subunits of TCRs, leading to the activation of
different second messenger cascades. Phosphorylated ITAMs
serve as binding sites for other signaling factor such as
Syk and ZAP-70, leading to their activation and
propagation of downstream events. In addition, Lck
regulates drug-induced apoptosis by interfering with the
mitochondrial death pathway. The apototic role of Lck is
independent of its primary function in T-cell signaling.
Blk is expressed specifically in B-cells. It is involved
in pre-BCR (B-cell receptor) signaling.

comprise the largest subfamily of receptor tyr kinases
(RTKs). Class EphB receptors bind to transmembrane
ephrin-B ligands. There are six vertebrate EhpB receptors
(EphB1-6), which display promiscuous interactions with
three ephrin-B ligands. One exception is EphB2, which
also interacts with ephrin A5. EphRs contain an
ephrin-binding domain and two fibronectin repeats
extracellularly, a transmembrane segment, and a
cytoplasmic tyr kinase domain. Binding of the ephrin
ligand to EphR requires cell-cell contact since both are
anchored to the plasma membrane. The resulting downstream
signals occur bidirectionally in both EphR-expressing
cells (forward signaling) and ephrin-expressing cells
(reverse signaling). Ephrin/EphR interaction mainly
results in cell-cell repulsion or adhesion. EphBRs play
important roles in synapse formation and plasticity,
spine morphogenesis, axon guidance, and angiogenesis. In
the intestinal epithelium, EphBRs are Wnt signaling
target genes that control cell compartmentalization. They
function as suppressors of color cancer progression.

responses to extracellular signals. In plants, MAPKs are
associated with physiological, developmental, hormonal,
and stress responses. Some plants show numerous gene
duplications of MAPKs. Arabidopsis thaliana harbors at
least 20 MAPKs, named AtMPK1-20. Oryza sativa contains at
least 17 MAPKs. There are two subtypes of plant MAPKs
based on the conserved phosphorylation motif present in
the activation loop, TEY and TDY. Arabidopsis thaliana
contains more TEY-type MAPKs than TDY-type, whereas the
reverse is true for Oryza sativa. This subfamily
represents the TDY subtype and is composed of Group D
plant MAPKs including Arabidopsis thaliana MPK18
(AtMPK18), Oryza sativa Blast- and Wound-induced MAPK1
(OsBWMK1), OsWJUMK1 (Wound- and JA-Uninducible MAPK1),
Zea mays MPK6, and the Medicago sativa TDY1 gene product.
OsBWMK1 enhances resistance to pathogenic infections. It
mediates stress-activated defense responses by activating
a transcription factor that affects the expression of
stress-related genes. AtMPK18 is involved in
microtubule-related functions.

subfamily members include EGFR (HER1, ErbB1), HER2
(ErbB2), HER3 (ErbB3), HER4 (ErbB4), and similar
proteins. The PTKc family is part of a larger superfamily
that includes the catalytic domains of other kinases such
as protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. The EGFR
proteins are receptor tyr kinases (RTKs) containing an
extracellular EGF-related ligand-binding region, a
transmembrane helix, and a cytoplasmic region with a tyr
kinase domain and a regulatory C-terminal tail. Unlike
other tyr kinases, phosphorylation of the activation loop
of EGFR proteins is not critical to their activation.
Instead, they are activated by ligand-induced
dimerization, resulting in the phosphorylation of tyr
residues in the C-terminal tail, which serve as binding
sites for downstream signaling molecules. Collectively,
they can recognize a variety of ligands including EGF,
TGFalpha, and neuregulins, among others. All four
subfamily members can form homo- or heterodimers. HER3
contains an impaired kinase domain and depends on its
heterodimerization partner for activation. EGFR subfamily
members are involved in signaling pathways leading to a
broad range of cellular responses including cell
proliferation, differentiation, migration, growth
inhibition, and apoptosis. Gain of function alterations,
through their overexpression, deletions, or point
mutations in their kinase domains, have been implicated
in various cancers. These receptors are targets of many
small molecule inhibitors and monoclonal antibodies used
in cancer therapy.

gamma-phosphoryl group from ATP to tyrosine (tyr)

largest subfamily of receptor tyr kinases (RTKs). In
general, class EphA receptors bind GPI-anchored ephrin-A
ligands. There are ten vertebrate EphA receptors
(EphA1-10), which display promiscuous interactions with
six ephrin-A ligands. EphRs contain an ephrin binding
domain and two fibronectin repeats extracellularly, a
transmembrane segment, and a cytoplasmic tyr kinase
domain. Binding of the ephrin ligand to EphR requires
cell-cell contact since both are anchored to the plasma
membrane. The resulting downstream signals occur
bidirectionally in both EphR-expressing cells (forward
signaling) and ephrin-expressing cells (reverse
signaling). Ephrin/EphR interaction mainly results in
cell-cell repulsion or adhesion, making it important in
neural development and plasticity, cell morphogenesis,
cell-fate determination, embryonic development, tissue
patterning, and angiogenesis. The EphA2 receptor is
overexpressed in tumor cells and tumor blood vessels in a
variety of cancers including breast, prostate, lung, and
colon. As a result, it is an attractive target for drug
design since its inhibition could affect several aspects
of tumor progression.

Ig5_Titin_like: domain similar to the M5, fifth
immunoglobulin (Ig)-like domain from the human titin C
terminus. Titin (also called connectin) is a fibrous
sarcomeric protein specifically found in vertebrate
striated muscle. Titin is gigantic; depending on isoform
composition it ranges from 2970 to 3700 kDa, and is of a
length that spans half a sarcomere. Titin largely
consists of multiple repeats of Ig-like and fibronectin
type 3 (FN-III)-like domains. Titin connects the ends of
myosin thick filaments to Z disks and extends along the
thick filament to the H zone, and appears to function
similar to an elastic band, keeping the myosin filaments
centered in the sarcomere during muscle contraction or
stretching.

is well-established. Syk is involved in the signaling
downstream of activated receptors (including B-cell and
Fc receptors) that contain ITAMs (immunoreceptor tyr
activation motifs), leading to processes such as cell
proliferation, differentiation, survival, adhesion,

expression has been detected in other cell types
(including epithelial cells, vascular endothelial cells,
neurons, hepatocytes, and melanocytes), suggesting a
variety of biological functions in non-immune cells. Syk
plays a critical role in maintaining vascular integrity
and in wound healing during embryogenesis. It also
regulates Vav3, which is important in osteoclast function
including bone development. In breast epithelial cells,
where Syk acts as a negative regulator for epidermal
growth factor receptor (EGFR) signaling, loss of Syk
expression is associated with abnormal proliferation
during cancer development suggesting a potential role as
a tumor suppressor. In mice, Syk has been shown to
inhibit malignant transformation of mammary epithelial
cells induced with murine mammary tumor virus (MMTV).

(STKs), c-Jun N-terminal kinase 2 (JNK2) subfamily,

part of a larger superfamily that includes the catalytic

mitogen-activated protein kinases (MAPKs) that are
involved in many stress-activated responses including
those during inflammation, neurodegeneration, apoptosis,
and persistent pain sensitization, among others.
Vetebrates harbor three different JNK genes (Jnk1, Jnk2,
and Jnk3). JNK1, like JNK2, is expressed in every cell
and tissue type. Initially it was thought that JNK1 and
JNK2 were functionally redundant as mice deficient in
either genes (Jnk1 or Jnk2) could survive but disruption
of both genes resulted in lethality. However, recent
studies have shown that JNK1 and JNK2 perform distinct
functions through specific binding partners and
substrates. JNK2 is specifically translocated to the
mitochondria during dopaminergic cell death. Specific
substrates include the microtubule-associated proteins
DCX and Tau, as well as TIF-IA which is involved in
ribosomal RNA synthesis regulation. Mice deficient in
Jnk2 show protection against arthritis, type 1 diabetes,
atherosclerosis, abdominal aortic aneurysm, cardiac cell
death, TNF-induced liver damage, and tumor growth,
indicating that JNK2 may play roles in the pathogenesis
of these diseases.

subfamily kinases are cytoplasmic (or nonreceptor) tyr
kinases containing the Src homology domains, SH3 and SH2,
N-terminal to the catalytic tyr kinase domain. They
negatively regulate the activity of Src kinases that are
anchored to the plasma membrane. To inhibit Src kinases,
Csk and Chk are translocated to the membrane via binding
to specific transmembrane proteins, G-proteins, or
adaptor proteins near the membrane. Csk catalyzes the tyr
phosphorylation of the regulatory C-terminal tail of Src
kinases, resulting in their inactivation. Chk inhibit Src
kinases using a noncatalytic mechanism by simply binding
to them. As negative regulators of Src kinases, Csk and
Chk play important roles in cell proliferation, survival,

MAPK that is not regulated by a MAPK kinase. It functions
downstream of the MAPK kinase kinase Tak1, which also
plays a role in activating the JNK and p38 MAPKs. The
Tak1/NLK pathways are regulated by Wnts, a family of
secreted proteins that is critical in the control of
asymmetric division and cell polarity. NLK can
phosphorylate transcription factors from the TCF/LEF
family, inhibiting their ability to activate the
transcription of target genes. In prostate cancer cells,
NLK is involved in regulating androgen receptor-mediated
transcription and its expression is altered during cancer
progression.

EphRs comprise the largest subfamily of receptor tyr
kinases (RTKs). In general, class EphA receptors bind
GPI-anchored ephrin-A ligands. There are ten vertebrate
EphA receptors (EphA1-10), which display promiscuous
interactions with six ephrin-A ligands. One exception is
EphA4, which also binds ephrins-B2/B3. EphRs contain an
ephrin-binding domain and two fibronectin repeats
extracellularly, a transmembrane segment, and a
cytoplasmic tyr kinase domain. Binding of the ephrin
ligand to EphR requires cell-cell contact since both are
anchored to the plasma membrane. The resulting downstream
signals occur bidirectionally in both EphR-expressing
cells (forward signaling) and ephrin-expressing cells
(reverse signaling). Ephrin/EphR interaction mainly
results in cell-cell repulsion or adhesion, making it
important in neural development and plasticity, cell
morphogenesis, cell-fate determination, embryonic
development, tissue patterning, and angiogenesis. EphARs
and ephrin-A ligands are expressed in multiple areas of
the developing brain, especially in the retina and
tectum. They are part of a system controlling
retinotectal mapping.

family; C-terminal Src kinase (Csk); catalytic (c)
domain. The PTKc family is part of a larger superfamily
that includes the catalytic domains of other kinases such
as protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. The Csk
subfamily kinases are cytoplasmic (or nonreceptor) tyr
kinases containing the Src homology domains, SH3 and SH2,
N-terminal to the catalytic tyr kinase domain. They
negatively regulate the activity of Src kinases that are
anchored to the plasma membrane. To inhibit Src kinases,
Csk is translocated to the membrane via binding to
specific transmembrane proteins, G-proteins, or adaptor
proteins near the membrane. Csk catalyzes the tyr
phosphorylation of the regulatory C-terminal tail of Src
kinases, resulting in their inactivation. Csk is
expressed in a wide variety of tissues. As a negative
regulator of Src, Csk plays a role in cell proliferation,
survival, and differentiation, and consequently, in
cancer development and progression. In addition, Csk also
shows Src-independent functions. It is a critical
component in G-protein signaling, and plays a role in
cytoskeletal reorganization and cell migration.

Vetebrates harbor three different JNK genes (Jnk1, Jnk2,
and Jnk3) that are alternatively spliced to produce at
least 10 isoforms. JNKs are specifically activated by the
MAPK kinases MKK4 and MKK7, which are in turn activated
by upstream MAPK kinase kinases as a result of different
stimuli including stresses such as ultraviolet (UV)
irradiation, hyperosmolarity, heat shock, or cytokines.
JNKs activate a large number of different substrates
based on specific stimulus, cell type, and cellular
condition, and may be implicated in seemingly
contradictory functions.

death, and neuronal death due to NGF deprivation,
oxidative stress, or exposure to beta-amyloid peptide.
This suggests that JNK3 may play roles in the

by MAP2Ks. MAPK6 is expressed ubiquitously with highest
amounts in brain and skeletal muscle. It may be involved
in the control of cell differentiation by negatively
regulating cell cycle progression in certain conditions.
It may also play a role in glucose-induced insulin
secretion. MAPK6 and MAPK4 cooperate to regulate the
activity of MAPK-activated protein kinase 5 (MK5),
leading to its relocation to the cytoplasm and exclusion
from the nucleus. The MAPK6/MK5 and MAPK4/MK5 pathways
may play critical roles in embryonic and post-natal
development.

(or c-Src) is a cytoplasmic (or non-receptor) tyr kinase,
containing an N-terminal SH4 domain with a myristoylation
site, followed by SH3 and SH2 domains, a tyr kinase
domain, and a regulatory C-terminal region with a
conserved tyr. It is activated by autophosphorylation at
the tyr kinase domain, and is negatively regulated by
phosphorylation at the C-terminal tyr by Csk (C-terminal
Src Kinase). c-Src is the vertebrate homolog of the
oncogenic protein (v-Src) from Rous sarcoma virus.
Together with other Src subfamily proteins, it is
involved in signaling pathways that regulate cytokine and
growth factor responses, cytoskeleton dynamics, cell
proliferation, survival, and differentiation. Src also
play a role in regulating cell adhesion, invasion, and
motility in cancer cells and tumor vasculature,
contributing to cancer progression and metastasis.
Elevated levels of Src kinase activity have been reported
in a variety of human cancers. Several inhibitors of Src
have been developed as anti-cancer drugs. Src is also
implicated in acute inflammatory responses and osteoclast
function.

TrkB is a member of the Trk subfamily of proteins, which
are receptor tyr kinases (RTKs) containing an
extracellular region with arrays of leucine-rich motifs
flanked by two cysteine-rich clusters followed by two
immunoglobulin-like domains, a transmembrane segment, and
an intracellular catalytic domain. Binding of TrkB to its
ligands, brain-derived neurotrophic factor (BDNF) or
neurotrophin 4 (NT4), results in receptor oligomerization
and activation of the catalytic domain. TrkB is broadly
expressed in the nervous system and in some non-neural
tissues. It plays important roles in cell proliferation,
differentiation, and survival. BDNF/Trk signaling plays a
key role in regulating activity-dependent synaptic
plasticity. TrkB also contributes to protection against
gp120-induced neuronal cell death. TrkB overexpression is
associated with poor prognosis in neuroblastoma (NB) and
other human cancers. It acts as a suppressor of anoikis
(detachment-induced apoptosis) and contributes to tumor
metastasis.

Vetebrates harbor three different JNK genes (Jnk1, Jnk2,
and Jnk3). JNK1, like JNK2, is expressed in every cell
and tissue type. Initially it was thought that JNK1 and
JNK2 were functionally redundant as mice deficient in
either genes (Jnk1 or Jnk2) could survive but disruption
of both genes resulted in lethality. However, recent
studies have shown that JNK1 and JNK2 perform distinct
functions through specific binding partners and
substrates. JNK1 specifically binds with JAMP
(JNK1-associated membrane protein), which regulates the
duration of JNK1 activity in response to stimuli.
Specific JNK1 substrates include Itch and SG10, which are
implicated in Th2 responses and airway inflammation, and
microtubule dynamics and axodendritic length,
respectively. Mice deficient in Jnk1 are protected
against arthritis, obesity, type 2 diabetes, cardiac cell
death, and non-alcoholic liver disease, suggesting that
JNK1 may play roles in the pathogenesis of these
diseases.

Kinases, Fyn and Yrk. Protein Tyrosine Kinase (PTK)
family; Fyn and Yrk kinases; catalytic (c) domain. The
PTKc family is part of a larger superfamily that includes
the catalytic domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Fyn and
Yrk are members of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases contain an N-terminal SH4 domain with a
myristoylation site, followed by SH3 and SH2 domains, a
tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr. They are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the C-terminal
tyr by Csk (C-terminal Src Kinase). Src proteins are
involved in signaling pathways that regulate cytokine and
growth factor responses, cytoskeleton dynamics, cell
proliferation, survival, and differentiation. Fyn,
together with Lck, plays a critical role in T-cell signal
transduction by phosphorylating ITAM (immunoreceptor tyr
activation motif) sequences on T-cell receptors,
ultimately leading to the proliferation and
differentiation of T-cells. In addition, Fyn is involved
in the myelination of neurons, and is implicated in
Alzheimer's and Parkinson's diseases. Yrk has been
detected only in chickens. It is primarily found in
neuronal and epithelial cells and in macrophages. It may
play a role in inflammation and in response to injury.

similar proteins. The PTKc family is part of a larger

catalyze the transfer of the gamma-phosphoryl group from

proteins are orphan receptor tyr kinases (RTKs)
containing an extracellular region with
immunoglobulin-like, cysteine-rich, and kringle domains,
a transmembrane segment, and an intracellular catalytic
domain. Ror RTKs are unrelated to the nuclear receptor
subfamily called retinoid-related orphan receptors
(RORs). RTKs are usually activated through ligand
binding, which causes dimerization and
autophosphorylation of the intracellular tyr kinase
catalytic domain. Ror kinases are expressed in many
tissues during development. They play important roles in
bone and heart formation. Mutations in human Ror2 result
in two different bone development genetic disorders,
recessive Robinow syndrome and brachydactyly type B.
Drosophila Ror is expressed only in the developing
nervous system during neurite outgrowth and neuronal
differentiation, suggesting a role for Drosophila Ror in
neural development. More recently, mouse Ror1 and Ror2
have also been found to play an important role in
regulating neurite growth in central neurons. Ror1 and
Ror2 are believed to have some overlapping and redundant
functions.

viruses. It displays functional overlap with other Src
subfamily members, particularly Src. It also shows some
unique functions such as binding to occludins,

a number of proteins in different cell types that Src
does not interact with, like JAK2 and gp130 in

Yes remains unclear, it appears to have a role in
regulating cell-cell interactions and vesicle trafficking
in polarized cells.

negatively regulate the activity of Src kinases that are
anchored to the plasma membrane. Chk is also referred to
as megakaryocyte-associated tyrosine kinase (Matk). To
inhibit Src kinases, Chk is translocated to the membrane
via binding to specific transmembrane proteins,
G-proteins, or adaptor proteins near the membrane. Chk
inhibit Src kinases using a noncatalytic mechanism by
simply binding to them. As a negative regulator of Src
kinases, Chk may play important roles in cell
proliferation, survival, and differentiation, and
consequently, in cancer development and progression. Chk
is expressed in brain and hematopoietic cells. Studies in
mice reveal that Chk is not functionally redundant with
Csk and that it plays an important role as a regulator of
immune responses. Chk also plays a role in neural
differentiation in a manner independent of Src by
enhancing Mapk activation via Ras-mediated signaling.

The PTKc family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. EphRs
comprise the largest subfamily of receptor tyr kinases
(RTKs). They can be classified into two classes (EphA and
EphB), according to their extracellular sequences, which
largely correspond to binding preferences for either
GPI-anchored ephrin-A ligands or transmembrane ephrin-B
ligands. Vertebrates have ten EphA and six EhpB
receptors, which display promiscuous ligand interactions
within each class. EphRs contain an ephrin binding domain
and two fibronectin repeats extracellularly, a
transmembrane segment, and a cytoplasmic tyr kinase
domain. Binding of the ephrin ligand to EphR requires
cell-cell contact since both are anchored to the plasma
membrane. This allows ephrin/EphR dimers to form, leading
to the activation of the intracellular tyr kinase domain.
The resulting downstream signals occur bidirectionally in
both EphR-expressing cells (forward signaling) and
ephrin-expressing cells (reverse signaling). The main
effect of ephrin/EphR interaction is cell-cell repulsion
or adhesion. Ephrin/EphR signaling is important in neural
development and plasticity, cell morphogenesis and
proliferation, cell-fate determination, embryonic
development, tissue patterning, and angiogenesis.

found in the Ig superfamily. The Ig superfamily is a
heterogenous group of proteins, built on a common fold
comprised of a sandwich of two beta sheets. Members of
this group are components of immunoglobulin, neuroglia,
cell surface glycoproteins, such as, T-cell receptors,
CD2, CD4, CD8, and membrane glycoproteins, such as,
butyrophilin and chondroitin sulfate proteoglycan core

subfamily proteins are cytoplasmic (or nonreceptor) tyr
kinases containing an N-terminal region with FCH
(Fes/Fer/CIP4 homology) and coiled-coil domains, followed
by a SH2 domain, and a C-terminal catalytic domain. The
genes for Fes (feline sarcoma) and Fps (Fujinami poultry
sarcoma) were first isolated from tumor-causing
retroviruses. The viral oncogenes encode chimeric Fes
proteins consisting of Gag sequences at the N-termini,
resulting in unregulated tyr kinase activity. Fes and Fer
kinases play roles in haematopoiesis, inflammation and
immunity, growth factor signaling, cytoskeletal
regulation, cell migration and adhesion, and the
regulation of cell-cell interactions. Fes and Fer show
redundancy in their biological functions.

duplications of MAPKs. Arabidopsis thaliana harbors at
least 20 MAPKs, named AtMPK1-20. There are two subtypes
of plant MAPKs based on the conserved phosphorylation
motif present in the activation loop, TEY and TDY. This
subfamily represents the TEY subtype and is further
subdivided into three groups (A, B, and C). Group A is
represented by AtMPK3, AtMPK6, Nicotiana tabacum BTF4
(NtNTF4), among others. They are mostly involved in
environmental and hormonal responses. AtMPK3 and AtMPK6
are also key regulators for stomatal development and
patterning. Group B is represented by AtMPK4, AtMPK13,
and NtNTF6, among others. They may be involved in both
cell division and environmental stress response. AtMPK4
also participates in regulating innate immunity. Group C
is represented by AtMPK1, AtMPK2, NtNTF3, Oryza sativa
MAPK4 (OsMAPK4), among others. They may also be involved
in stress responses. AtMPK1 and AtMPK2 are activated
following mechanical injury and in the presence of stress
chemicals such as jasmonic acid, hydrogen peroxide and
abscisic acid. OsMAPK4 is also called OsMSRMK3 for
Multiple Stress-Responsive MAPK3.

catalyze the transfer of the gamma-phosphoryl group from

TrkC is a member of the Trk subfamily of proteins, which
are receptor tyr kinases (RTKs) containing an
extracellular region with arrays of leucine-rich motifs
flanked by two cysteine-rich clusters followed by two
immunoglobulin-like domains, a transmembrane segment, and
an intracellular catalytic domain. Binding of TrkC to its
ligand, neurotrophin 3 (NT3), results in receptor
oligomerization and activation of the catalytic domain.
TrkC is broadly expressed in the nervous system and in
some non-neural tissues including the developing heart.
NT3/TrkC signaling plays an important role in the
innervation of the cardiac conducting system and the
development of smooth muscle cells. Mice deficient with
NT3 and TrkC have multiple heart defects. NT3/TrkC
signaling is also critical for the development and
maintenance of enteric neurons that are important for the
control of gut peristalsis.

p38delta subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. p38 kinases are mitogen-activated protein
kinases (MAPKs), serving as important mediators of
cellular responses to extracellular signals. They are
activated by the MAPK kinases MKK3 and MKK6, which in
turn are activated by upstream MAPK kinase kinases
including TAK1, ASK1, and MLK3, in response to cellular
stresses or inflammatory cytokines. Vertebrates contain
four isoforms of p38, named alpha, beta, gamma, and
delta. p38delta, also called MAPK13, is found in skeletal
muscle, heart, lung, testis, pancreas, and small
intestine. It regulates microtubule function by
phosphorylating Tau. It activates the c-jun promoter and
plays a role in G2 cell cycle arrest. It also controls
the degration of c-Myb, which is associated with myeloid
leukemia and poor prognosis in colorectal cancer.
p38delta is the main isoform involved in regulating the
differentiation and apoptosis of keratinocytes.

Ron are receptor tyr kinases (RTKs) composed of an
alpha-beta heterodimer. The extracellular alpha chain is
disulfide linked to the beta chain, which contains an
extracellular ligand-binding region with a sema domain, a
PSI domain and four IPT repeats, a transmembrane segment,
and an intracellular catalytic domain. Binding to their
ligands leads to receptor dimerization,
autophosphorylation, activation, and intracellular
signaling. Met binds to the ligand, hepatocyte growth
factor/scatter factor (HGF/SF), and is also called the
HGF receptor. HGF/Met signaling plays a role in growth,
transformation, cell motility, invasion, metastasis,
angiogenesis, wound healing, and tissue regeneration.
Aberrant expression of Met through mutations or gene
amplification is associated with many human cancers
including hereditary papillary renal and gastric
carcinomas. The ligand for Ron is macrophage stimulating
protein (MSP). Ron signaling is important in regulating
cell motility, adhesion, proliferation, and apoptosis.
Aberrant Ron expression is implicated in tumorigenesis
and metastasis.

in that a receptor may be activated by several ligands
and a ligand may bind to more that one type of receptor.
Alternative splicing of FGFR1 transcripts produces a
variety of isoforms, which are differentially expressed
in cells. FGFR1 binds the ligands, FGF1 and FGF2, with
high affinity and has also been reported to bind FGF4,
FGF6, and FGF9. FGFR1 signaling is critical in the
control of cell migration during embryo development. It
promotes cell proliferation in fibroblasts. Nuclear FGFR1
plays a role in the regulation of transcription.
Mutations, insertions or deletions of FGFR1 have been
identified in patients with Kallman's syndrome (KS), an
inherited disorder characterized by hypogonadotropic
hypogonadism and loss of olfaction. Aberrant FGFR1
expression has been found in some human cancers including
8P11 myeloproliferative syndrome (EMS), breast cancer,
and pancreatic adenocarcinoma.

EGFR (HER, ErbB) subfamily of proteins, which are
receptor tyr kinases (RTKs) containing an extracellular
EGF-related ligand-binding region, a transmembrane helix,
and a cytoplasmic region with a tyr kinase domain and a
regulatory C-terminal tail. Unlike other tyr kinases,
phosphorylation of the activation loop of EGFR proteins
is not critical to their activation. Instead, they are
activated by ligand-induced dimerization, leading to the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. Ligands that bind HER4 fall into two groups,
the neuregulins (or heregulins) and some EGFR (HER1)
ligands including betacellulin, HBEGF, and epiregulin.
All four neuregulins (NRG1-4) interact with HER4. Upon
ligand binding, HER4 forms homo- or heterodimers with
other HER proteins. HER4 is essential in embryonic
development. It is implicated in mammary gland, cardiac,
and neural development. As a postsynaptic receptor of
NRG1, HER4 plays an important role in synaptic plasticity
and maturation. The impairment of NRG1/HER4 signaling may
contribute to schizophrenia.

and serves as the ligand (Wnt) binding domain of Ryk. Ryk
is expressed in many different tissues both during
development and in adults, suggesting a widespread
function. It acts as a chemorepulsive axon guidance
receptor of Wnt glycoproteins and is responsible for the
establishment of axon tracts during the development of
the central nervous system. In addition, studies in mice
reveal that Ryk is essential in skeletal, craniofacial,

involved in the control of cell-cycle progression,
transcription, and neuronal function. CDK8 can act as a
negative or positive regulator of transcription,
depending on the scenario. Together with its regulator,
cyclin C, it reversibly associates with the multi-subunit
core Mediator complex, a cofactor that is involved in
regulating RNA polymerase II (RNAP II)-dependent
transcription. CDK8 phosphorylates cyclin H, a subunit of
the general transcription factor TFIIH, which results in
the inhibition of TFIIH-dependent phosphorylation of the
C-terminal domain (CTD) of RNAP II, facilitating the
inhibition of transcription. It has also been shown to
promote transcription by a mechanism that is likely to
involve RNAP II phosphorylation. CDK8 also functions as a
stimulus-specific positive coregulator of p53
transcriptional responses.

member of the DDR subfamily, which are receptor tyr
kinases (RTKs) containing an extracellular discoidin
homology domain, a transmembrane segment, an extended
juxtamembrane region, and an intracellular catalytic
domain. The binding of the ligand, collagen, to DDRs
results in a slow but sustained receptor activation. DDR2
binds mostly to fibrillar collagens. More recently, it
has been reported to also bind collagen X. DDR2 is widely
expressed in many tissues with the highest levels found
in skeletal muscle, skin, kidney and lung. It is
important in cell proliferation and development. Mice,
with a deletion of DDR2, suffer from dwarfism and delayed
healing of epidermal wounds. DDR2 also contributes to
collagen (type I) regulation by inhibiting
fibrillogenesis and altering the morphology of collagen
fibers. It is also expressed in immature dendritic cells
(DCs), where it plays a role in DC activation and
function.

Tie2 is a receptor tyr kinase (RTK) containing an

Tie2 is expressed mainly in endothelial cells and
hematopoietic stem cells. It is also found in a subset of
tumor-associated monocytes and eosinophils. The
angiopoietins (Ang-1 to Ang-4) serve as ligands for Tie2.
The binding of Ang-1 to Tie2 leads to receptor
autophosphorylation and activation, promoting cell
migration and survival. In contrast, Ang-2 binding to
Tie2 does not result in the same response, suggesting
that Ang-2 may function as an antagonist. Tie2 signaling
plays key regulatory roles in vascular integrity and

TrkA is a member of the Trk subfamily of proteins, which

extracellular region with arrays of leucine-rich motifs
flanked by two cysteine-rich clusters followed by two
immunoglobulin-like domains, a transmembrane segment, and
an intracellular catalytic domain. Binding of TrkA to its
ligand, nerve growth factor (NGF), results in receptor
oligomerization and activation of the catalytic domain.
TrkA is expressed mainly in neural-crest-derived sensory
and sympathetic neurons of the peripheral nervous system,
and in basal forebrain cholinergic neurons of the central
nervous system. It is critical for neuronal growth,
differentiation and survival. Alternative TrkA splicing
has been implicated as a pivotal regulator of
neuroblastoma (NB) behavior. Normal TrkA expression is
associated with better NB prognosis, while the
hypoxia-regulated TrkAIII splice variant promotes NB
pathogenesis and progression. Aberrant TrkA expression
has also been demonstrated in non-neural tumors including
prostate, breast, lung, and pancreatic cancers.

fibroblast growth factor (FGF) receptor and similar
proteins. Ig2_FGFR_like: domain similar to the second
immunoglobulin (Ig)-like domain of fibroblast growth
factor (FGF) receptor. FGF receptors bind FGF signaling
polypeptides. FGFs participate in multiple processes such
as morphogenesis, development, and angiogenesis. FGFs
bind to four FGF receptor tyrosine kinases (FGFR1, -2,
-3, -4). Receptor diversity is controlled by alternative
splicing producing splice variants with different ligand
binding characteristics and different expression
patterns. FGFRs have an extracellular region comprised of
three Ig-like domains, a single transmembrane helix, and
an intracellular tyrosine kinase domain. Ligand binding
and specificity reside in the Ig-like domains 2 and 3,
and the linker region that connects these two. FGFR
activation and signaling depend on FGF-induced
dimerization, a process involving cell surface heparin or
heparin sulfate proteoglycans. This group also contains
fibroblast growth factor (FGF) receptor_like-1(FGFRL1).
FGFRL1 does not have a protein tyrosine kinase domain at
its C terminus; neither does its cytoplasmic domain
appear to interact with a signaling partner. It has been
suggested that FGFRL1 may not have any direct signaling
function, but instead acts as a decoy receptor trapping
FGFs and preventing them from binding other receptors.

serine/threonine kinases (STKs), protein tyrosine
kinases, RIO kinases, aminoglycoside phosphotransferase,
choline kinase, and phosphoinositide 3-kinase. The
pseudokinase domain shows similarity to protein kinases
but lacks crucial residues for catalytic activity. STRAD
forms a complex with the scaffolding protein MO25, and
the STK, LKB1, resulting in the activation of the kinase.
In the complex, LKB1 phosphorylates and activates
adenosine monophosphate-activated protein kinases
(AMPKs), which regulate cell energy metabolism and cell
polarity. LKB1 is a tumor suppressor linked to the rare
inherited disease, Peutz-Jeghers syndrome, which is
characterized by a predisposition to benign polyps and
hyperpigmentation of the buccal mucosa. There are two
forms of STRAD, alpha and beta, that complex with LKB1
and MO25. The structure of STRAD-alpha is available and
shows that this protein binds ATP, has an ordered
activation loop, and adopts a closed conformation typical
of fully active protein kinases. It does not possess
activity due to nonconservative substitutions of
essential catalytic residues. ATP binding enhances the
affinity of STRAD for MO25. The conformation of
STRAD-alpha stabilized through ATP and MO25 may be needed
to activate LKB1.

in that a receptor may be activated by several ligands
and a ligand may bind to more that one type of receptor.
Many FGFR3 splice variants have been reported with the
IIIb and IIIc isoforms being the predominant forms. FGFR3
IIIc is the isoform expressed in chondrocytes, the cells
affected in dwarfism, while IIIb is expressed in
epithelial cells. FGFR3 ligands include FGF1, FGF2, FGF4,
FGF8, FGF9, and FGF23. It is a negative regulator of long
bone growth. In the cochlear duct and in the lens, FGFR3
is involved in differentiation while it appears to have a
role in cell proliferation in epithelial cells. Germline
mutations in FGFR3 are associated with skeletal disorders
including several forms of dwarfism. Some missense
mutations are associated with multiple myeloma and
carcinomas of the bladder and cervix. Overexpression of
FGFR3 is found in thyroid carcinoma.

C-ros. Protein Tyrosine Kinases (PTK) family; C-ros and
Drosophila Sevenless proteins; catalytic (c) domain. The
PTKc family is part of a larger superfamily that includes
the catalytic domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. The
proto-oncogene c-ros encodes an orphan receptor tyr
kinase (RTK) with an unknown ligand. RTKs contain an
extracellular ligand-binding domain, a transmembrane
region, and an intracellular tyr kinase domain. RTKs are
usually activated through ligand binding, which causes
dimerization and autophosphorylation of the intracellular
tyr kinase catalytic domain. C-ros is expressed in
embryonic cells of the kidney, intestine and lung, but
disappears soon after birth. It persists only in the
adult epididymis. Male mice bearing inactive mutations of
c-ros lack the initial segment of the epididymis and are
infertile. The Drosophila protein, Sevenless, is required
for the specification of the R7 photoreceptor cell during
eye development.

HER2/neu); catalytic (c) domain. The PTKc family is part
of a larger superfamily that includes the catalytic
domains of other kinases such as protein serine/threonine
kinases, RIO kinases, and phosphoinositide 3-kinase
(PI3K). PTKs catalyze the transfer of the
gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. HER2 is a member of the
EGFR (HER, ErbB) subfamily of proteins, which are
receptor tyr kinases (RTKs) containing an extracellular
EGF-related ligand-binding region, a transmembrane helix,
and a cytoplasmic region with a tyr kinase domain and a
regulatory C-terminal tail. Unlike other tyr kinases,
phosphorylation of the activation loop of EGFR proteins
is not critical to their activation. Instead, they are
activated by ligand-induced dimerization, leading to the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. HER2 does not bind to any known EGFR subfamily
ligands, but contributes to the kinase activity of all
possible heterodimers. It acts as the preferred partner
with other ligand-bound EGFR proteins and functions as a
signal amplifier, with the HER2-HER3 heterodimer being
the most potent pair in mitogenic signaling. HER2 plays
an important role in cell development, proliferation,
survival and motility. Overexpression of HER2 results in
its activation and downstream signaling, even in the
absence of ligand. HER2 overexpression, mainly due to
gene amplification, has been shown in a variety of human
cancers. Its role in breast cancer is especially
well-documented. HER2 is up-regulated in about 25% of
breast tumors and is associated with increases in tumor
aggressiveness, recurrence and mortality. HER2 is a
target for monoclonal antibodies and small molecule
inhibitors, which are being developed as treatments for
cancer. The first humanized antibody approved for
clinical use is Trastuzumab (Herceptin), which is being
used in combination with other therapies to improve the
survival rates of patients with HER2-overexpressing
breast cancer.

First Ig domain of contactins. Contactins are neural cell
adhesion molecules and are comprised of six Ig domains
followed by four fibronectin type III(FnIII) domains
anchored to the membrane by glycosylphosphatidylinositol.
The first four Ig domains form the intermolecular binding
fragment, which arranges as a compact U-shaped module via
contacts between Ig domains 1 and 4, and between Ig
domains 2 and 3. Contactin-2 (TAG-1, axonin-1) may play a
part in the neuronal processes of neurite outgrowth, axon
guidance and fasciculation, and neuronal migration. This
group also includes contactin-1 and contactin-5. The
different contactins show different expression patterns
in the central nervous system. During development and in
adulthood, contactin-2 is transiently expressed in
subsets of central and peripheral neurons. Contactin-5 is
expressed specifically in the rat postnatal nervous
system, peaking at about 3 weeks postnatal, and a lack of
contactin-5 (NB-2) results in an impairment of neuronal
activity in the rat auditory system. Contactin-5 is
highly expressed in the adult human brain in the
occipital lobe and in the amygdala. Contactin-1 is
differentially expressed in tumor tissues and may,
through a RhoA mechanism, facilitate invasion and
metastasis of human lung adenocarcinoma.

subfamily, which are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
three immunoglobulin-like domains, a transmembrane
segment, and an intracellular catalytic domain. The
binding of FGFRs to their ligands, the FGFs, results in
receptor dimerization and activation, and intracellular
signaling. The binding of FGFs to FGFRs is promiscuous,
in that a receptor may be activated by several ligands
and a ligand may bind to more that one type of receptor.
Unlike other FGFRs, there is only one splice form of
FGFR4. It binds FGF1, FGF2, FGF6, FGF19, and FGF23. FGF19
is a selective ligand for FGFR4. Although disruption of
FGFR4 in mice causes no obvious phenotype, in vivo
inhibition of FGFR4 in cultured skeletal muscle cells
resulted in an arrest of muscle progenitor
differentiation. FGF6 and FGFR4 are uniquely expressed in
myofibers and satellite cells. FGF6/FGFR4 signaling
appears to play a key role in the regulation of muscle
regeneration. A polymorphism in FGFR4 is found in head
and neck squamous cell carcinoma.

Fibroblast Growth Factor Receptors. Protein Tyrosine
Kinase (PTK) family; Fibroblast Growth Factor Receptor
(FGFR) subfamily; catalytic (c) domain. The FGFR
subfamily consists of FGFR1, FGFR2, FGFR3, FGFR4, and
similar proteins. The PTKc family is part of a larger
superfamily that includes the catalytic domains of other
kinases such as protein serine/threonine kinases, RIO
kinases, and phosphoinositide 3-kinase (PI3K).PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
FGFR subfamily members are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
three immunoglobulin-like domains, a transmembrane
segment, and an intracellular catalytic domain. The
binding of FGFRs to their ligands, the FGFs, and to
heparin/heparan sulfate (HS) results in the formation of
a ternary complex, which leads to receptor dimerization
and activation, and intracellular signaling. There are at
least 23 FGFs and four types of FGFRs. The binding of
FGFs to FGFRs is promiscuous, in that a receptor may be
activated by several ligands and a ligand may bind to
more that one type of receptor. FGF/FGFR signaling is
important in the regulation of embryonic development,
homeostasis, and regenerative processes. Depending on the
cell type and stage, FGFR signaling produces diverse
cellular responses including proliferation, growth
arrest, differentiation, and apoptosis. Aberrant
signaling leads to many human diseases such as skeletal,
olfactory, and metabolic disorders, as well as cancer.

in the development of melanocytes, germ cells, mast
cells, hematopoietic stem cells, the interstitial cells
of Cajal, and the pacemaker cells of the GI tract. Kit
signaling is involved in major cellular functions
including cell survival, proliferation, differentiation,
adhesion, and chemotaxis. Mutations in Kit, which result
in constitutive ligand-independent activation, are found
in human cancers such as gastrointestinal stromal tumor
(GIST) and testicular germ cell tumor (TGCT). The
aberrant expression of Kit and/or SCF is associated with
other tumor types such as systemic mastocytosis and
cancers of the breast, neurons, lung, prostate, colon,
and rectum. Although the structure of the human Kit
catalytic domain is known, it is excluded from this
specific alignment model because it contains a deletion
in its sequence.

The Aatyk subfamily is also referred to as the lemur

Aatyk proteins are mostly receptor tyr kinases (RTKs)
containing a transmembrane segment and a long C-terminal
cytoplasmic tail with a catalytic domain. Aatyk1 does not
contain a transmembrane segment and is a cytoplasmic (or
nonreceptor) kinase. Aatyk proteins are classified as tyr
kinases based on overall sequence similarity and the
phylogenetic tree. However, analysis of catalytic
residues suggests that Aatyk proteins may be
multispecific kinases, functioning also as
serine/threonine kinases. They are involved in neural
differentiation, nerve growth factor (NGF) signaling,
apoptosis, and spermatogenesis.

induces a variety of cellular effects including
migration, survival, and proliferation. It is critical in
regulating embryonic vascular development and
angiogenesis. VEGFR2 is the major signal transducer in
pathological angiogenesis including cancer and diabetic

transfer of the gamma-phosphoryl group from ATP to

IGF-1R are receptor tyr kinases (RTKs) composed of two
alphabeta heterodimers. Binding of the ligand (insulin,
IGF-1, or IGF-2) to the extracellular alpha subunit
activates the intracellular tyr kinase domain of the
transmembrane beta subunit. Receptor activation leads to
autophosphorylation, stimulating downstream kinase
activities, which initiate signaling cascades and
biological function. InsR and IGF-1R, which share 84%
sequence identity in their kinase domains, display
physiologically distinct yet overlapping functions in
cell growth, differentiation, and metabolism. InsR
activation leads primarily to metabolic effects while
IGF-1R activation stimulates mitogenic pathways. In cells
expressing both receptors, InsR/IGF-1R hybrids are found
together with classical receptors. Both receptors can
interact with common adaptor molecules such as IRS-1 and
IRS-2.

Neural Cell Adhesion Molecule NCAM-1 (NCAM).
Ig3_NCAM-1_like: domain similar to the third
immunoglobulin (Ig)-like domain of Neural Cell Adhesion
Molecule NCAM-1 (NCAM). NCAM plays important roles in the
development and regeneration of the central nervous
system, in synaptogenesis and neural migration. NCAM
mediates cell-cell and cell-substratum recognition and
adhesion via homophilic (NCAM-NCAM), and heterophilic
(NCAM-non-NCAM), interactions. NCAM is expressed as three
major isoforms having different intracellular extensions.
The extracellular portion of NCAM has five N-terminal
Ig-like domains and two fibronectin type III domains. The
double zipper adhesion complex model for NCAM homophilic
binding involves Ig1, Ig2, and Ig3. By this model,
Ig1,and Ig2 mediate dimerization of NCAM molecules
situated on the same cell surface (cis interactions), and
Ig3 domains mediate interactions between NCAM molecules
expressed on the surface of opposing cells (trans
interactions), through binding to the Ig1 and Ig2
domains. The adhesive ability of NCAM is modulated by the
addition of polysialic acid chains to the fifth Ig-like
domain.

Ig2_VEGFR: Second immunoglobulin (Ig)-like domain of
vascular endothelial growth factor receptor (VEGFR). The
VEGFRs have an extracellular component with seven Ig-like
domains, a transmembrane segment, and an intracellular
tyrosine kinase domain interrupted by a kinase-insert
domain. The VEGFR family consists of three members,
VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1) and VEGFR-3 (Flt-4).
VEGFRs bind VEGFs with high affinity at the Ig-like
domains. VEGF-A is important to the growth and
maintenance of vascular endothelial cells and to the
development of new blood- and lymphatic-vessels in
physiological and pathological states. VEGFR-2 is a major
mediator of the mitogenic, angiogenic and microvascular
permeability-enhancing effects of VEGF-A. VEGFR-1 may
play an inhibitory part in these processes by binding
VEGF and interfering with its interaction with VEGFR-2.
VEGFR-1 has a signaling role in mediating monocyte
chemotaxis. VEGFR-2 and -1 may mediate a chemotactic and
a survival signal in hematopoietic stem cells or leukemia
cells. VEGFR-3 has been shown to be involved in tumor
angiogenesis and growth.

of the Janus kinase (Jak) subfamily of proteins, which
are cytoplasmic (or nonreceptor) tyr kinases containing
an N-terminal FERM domain, followed by a Src homology 2
(SH2) domain, a pseudokinase domain, and a C-terminal tyr
kinase domain. The pseudokinase domain shows similarity
to tyr kinases but lacks crucial residues for catalytic
activity and ATP binding. It modulates the kinase
activity of the C-terminal catalytic domain. Jaks are
crucial for cytokine receptor signaling. They are
activated by autophosphorylation upon cytokine-induced
receptor aggregation, and subsequently trigger downstream
signaling events such as the phosphorylation of signal
transducers and activators of transcription (STATs). Jak2
is widely expressed in many tissues while Jak3 is
expressed only in hematopoietic cells. Jak2 is essential
for the signaling of hormone-like cytokines such as
growth hormone, erythropoietin, thrombopoietin, and
prolactin, as well as some IFNs and cytokines that signal
through the IL-3 and gp130 receptors. Jak3 binds the
shared receptor subunit common gamma chain and thus, is
essential in the signaling of cytokines that use it such
as IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21. Disruption
of Jak2 in mice results in an embryonic lethal phenotype
with multiple defects including erythropoietic and
cardiac abnormalities. It is the only Jak gene that
results in a lethal phenotype when disrupted in mice. A
mutation in the pseudokinase domain of Jak2, V617F, is
present in many myeloproliferative diseases, including
almost all patients with polycythemia vera, and 50% of
patients with essential thrombocytosis and myelofibrosis.
Jak3 is important in lymphoid development and myeloid
cell differentiation. Inactivating mutations in Jak3 have
been reported in humans with severe combined
immunodeficiency (SCID).

protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. The pseudokinase domain shows similarity to
protein kinases but lacks crucial residues for catalytic
activity. STRAD forms a complex with the scaffolding
protein MO25, and the STK, LKB1, resulting in the
activation of the kinase. In the complex, LKB1
phosphorylates and activates adenosine
monophosphate-activated protein kinases (AMPKs), which
regulate cell energy metabolism and cell polarity. LKB1
is a tumor suppressor linked to the rare inherited
disease, Peutz-Jeghers syndrome, which is characterized
by a predisposition to benign polyps and
hyperpigmentation of the buccal mucosa. There are two
forms of STRAD, alpha and beta, that complex with LKB1
and MO25. The structure of STRAD-alpha is available and
shows that this protein binds ATP, has an ordered
activation loop, and adopts a closed conformation typical
of fully active protein kinases. It does not possess
activity due to nonconservative substitutions of
essential catalytic residues. ATP binding enhances the
affinity of STRAD for MO25. The conformation of
STRAD-alpha, stabilized through ATP and MO25, may be
needed to activate LKB1. A mutation which results in a
truncation of a C-terminal part of the human STRAD-alpha
pseudokinase domain and disrupts its association with
LKB1, leads to PMSE (polyhydramnios, megalencephaly,
symptomatic epilepsy) syndrome. Several splice variants
of STRAD-alpha exist which exhibit different effects on
the localization and activation of LKB1.

>gnl|CDD|133238 cd05107, PTKc_PDGFR_beta, Catalytic domain of the Protein Tyrosine
Kinase, Platelet Derived Growth Factor Receptor beta.
Protein Tyrosine Kinase (PTK) family; Platelet Derived
Growth Factor Receptor (PDGFR) beta; catalytic (c)
domain. The PTKc family is part of a larger superfamily
that includes the catalytic domains of other kinases such
as protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. PDGFR beta
is a receptor tyr kinase (RTK) containing an
extracellular ligand-binding region with five
immunoglobulin-like domains, a transmembrane segment, and
an intracellular catalytic domain. The binding to its
ligands, the PDGFs, leads to receptor dimerization, trans
phosphorylation and activation, and intracellular
signaling. PDGFR beta forms homodimers or heterodimers
with PDGFR alpha, depending on the nature of the PDGF
ligand. PDGF-BB and PDGF-DD induce PDGFR beta
homodimerization. PDGFR signaling plays many roles in
normal embryonic development and adult physiology. PDGFR
beta signaling leads to a variety of cellular effects
including the stimulation of cell growth and chemotaxis,
as well as the inhibition of apoptosis and GAP junctional
communication. It is critical in normal angiogenesis as
it is involved in the recruitment of pericytes and smooth
muscle cells essential for vessel stability. Aberrant
PDGFR beta expression is associated with some human
cancers. The continuously-active fusion proteins of PDGFR
beta with COL1A1 and TEL are associated with
dermatofibrosarcoma protuberans (DFSP) and a subset of
chronic myelomonocytic leukemia (CMML), respectively.

fibroblast growth factor (FGF) receptor_like-1(FGFRL1).
Ig2_FGFRL1-like: second immunoglobulin (Ig)-like domain
of fibroblast growth factor (FGF)
receptor_like-1(FGFRL1). FGFRL1 is comprised of a signal
peptide, three extracellular Ig-like modules, a
transmembrane segment, and a short intracellular domain.
FGFRL1 is expressed preferentially in skeletal tissues.
Similar to FGF receptors, the expressed protein interacts
specifically with heparin and with FGF2. FGFRL1 does not
have a protein tyrosine kinase domain at its C terminus;
neither does its cytoplasmic domain appear to interact
with a signaling partner. It has been suggested that
FGFRL1 may not have any direct signaling function, but
instead acts as a decoy receptor trapping FGFs and
preventing them from binding other receptors.

of macrophages and osteoclasts. It leads to increases in
gene transcription and protein translation, and induces
cytoskeletal remodeling. CSF-1R signaling leads to a
variety of cellular responses including survival,
proliferation, and differentiation of target cells. It
plays an important role in innate immunity, tissue
development and function, and the pathogenesis of some
diseases including atherosclerosis and cancer. CSF-1R
signaling is also implicated in mammary gland development
during pregnancy and lactation. Aberrant CSF-1/CSF-1R
expression correlates with tumor cell invasiveness, poor
clinical prognosis, and bone metastasis in breast cancer.
Although the structure of the human CSF-1R catalytic
domain is known, it is excluded from this specific
alignment model because it contains a deletion in its
sequence.

of diseases including schizophrenia, multiple sclerosis,
and breast cancer. There are four members of the
neuregulin gene family (NRG1, -2, -3, and -4). The NRG-1
protein, binds to and activates the tyrosine kinases
receptors ErbB3 and ErbB4, initiating signaling cascades.
The other NRGs proteins bind one or the other or both of
these ErbBs. NRG-1 has multiple functions; for example,
in the brain it regulates various processes such as
radial glia formation and neuronal migration, dendritic
development, and expression of neurotransmitters
receptors; in the peripheral nervous system NRG-1
regulates processes such as target cell differentiation,
and Schwann cell survival. There are many NRG-1 isoforms,
which arise from the alternative splicing of mRNA. Less
is known of the functions of the other NRGs. NRG-2 and -3
are expressed predominantly in the nervous system. NRG-2
is expressed by motor neurons and terminal Schwann cells,
and is concentrated near synaptic sites and may be a
signal that regulates synaptic differentiation. NRG-4 has
been shown to direct pancreatic islet cell development
towards the delta-cell lineage.

myosin light-chain kinase (MLCK). Ig8_MLCK: the eighth
immunoglobulin (Ig)-like domain of human myosin
light-chain kinase (MLCK). MLCK is a key regulator of
different forms of cell motility involving actin and
myosin II. Agonist stimulation of smooth muscle cells
increases cytosolic Ca2+, which binds calmodulin. This
Ca2+-calmodulin complex in turn binds to and activates
MLCK. Activated MLCK leads to the phosphorylation of the
20 kDa myosin regulatory light chain (RLC) of myosin II
and the stimulation of actin-activated myosin MgATPase
activity. MLCK is widely present in vertebrate tissues;
it phosphorylates the 20 kDa RLC of both smooth and
nonmuscle myosin II. Phosphorylation leads to the
activation of the myosin motor domain and altered
structural properties of myosin II. In smooth muscle MLCK
it is involved in initiating contraction. In nonmuscle
cells, MLCK may participate in cell division and cell
motility; it has been suggested MLCK plays a role in
cardiomyocyte differentiation and contraction through
regulation of nonmuscle myosin II.

stem cell factor receptor (SCFR) and similar proteins.
Ig4_SCFR_like; fourth immunoglobulin (Ig)-like domain of
stem cell factor receptor (SCFR). In addition to SCFR
this group also includes the fourth Ig domain of
platelet-derived growth factor receptors (PDGFR), alpha
and beta, the fourth Ig domain of macrophage colony
stimulating factor (M-CSF), and the Ig domain of the
receptor tyrosine kinase KIT. SCFR and the PDGFR alpha
and beta have similar organization: an extracellular
component having five Ig-like domains, a transmembrane
segment, and a cytoplasmic portion having protein
tyrosine kinase activity. SCFR and its ligand SCF are
critical for normal hematopoiesis, mast cell
development, melanocytes and gametogenesis. SCF binds to
the second and third Ig-like domains of SCFR, this
fourth Ig-like domain participates in SCFR dimerization,
which follows ligand binding. Deletion of this fourth
SCFR_Ig-like domain abolishes the ligand-induced
dimerization of SCFR and completely inhibits signal
transduction. PDGF is a potent mitogen for connective
tissue cells. PDGF-stimulated processes are mediated by
three different PDGFs (PDGF-A,-B, and C). PDGFR alpha
binds to all three PDGFs, whereas the PDGFR beta, binds
only to PDGF-B. In mice, PDGFR alpha, and PDGFR beta,
are essential for normal development.

Ig2_VEGF-2: Second immunoglobulin (Ig)-like domain of
vascular endothelial growth factor receptor 2 (VEGFR-2).
The VEGFRs have an extracellular component with seven
Ig-like domains, a transmembrane segment, and an
intracellular tyrosine kinase domain interrupted by a
kinase-insert domain. VEGFRs bind VEGFs with high
affinity at the Ig-like domains. VEGFR-2 (KDR/Flk-1) is
a major mediator of the mitogenic, angiogenic and
microvascular permeability-enhancing effects of VEGF-A;
VEGF-A is important to the growth and maintenance of
vascular endothelial cells and to the development of new
blood- and lymphatic-vessels in physiological and
pathological states. VEGF-A also interacts with VEGFR-1,
which it binds more strongly than VEGFR-2. VEGFR-2 and
-1 may mediate a chemotactic and a survival signal in
hematopoietic stem cells or leukemia cells.

subfamily; catalytic (c) domain. The PTKc family is part
of a larger superfamily that includes the catalytic
domains of other kinases such as protein serine/threonine
kinases, RIO kinases, and phosphoinositide 3-kinase
(PI3K). The Axl subfamily consists of Axl, Tyro3 (or
Sky), Mer (or Mertk), and similar proteins. PTKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Axl
subfamily members are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
two immunoglobulin-like domains followed by two
fibronectin type III repeats, a transmembrane segment,
and an intracellular catalytic domain. Binding to their
ligands, Gas6 and protein S, leads to receptor
dimerization, autophosphorylation, activation, and
intracellular signaling. Axl subfamily members are
implicated in a variety of cellular effects including
survival, proliferation, migration, and phagocytosis.
They are also associated with several types of cancer as
well as inflammatory, autoimmune, vascular, and kidney
diseases. Mer is named after its original reported
expression pattern (monocytes, epithelial, and
reproductive tissues). It is required for the ingestion
of apoptotic cells by phagocytes such as macrophages,
retinal pigment epithelial cells, and dendritic cells.
Mer is also important in maintaining immune homeostasis.

domain similar to the first immunoglobulin (Ig)-like
domain in Robo (roundabout) receptors. Robo receptors
play a role in the development of the central nervous
system (CNS), and are receptors of Slit protein. Slit is
a repellant secreted by the neural cells in the midline.
Slit acts through Robo to prevent most neurons from
crossing the midline from either side. Three mammalian
Robo homologs (robo1, -2, and -3), and three mammalian
Slit homologs (Slit-1,-2, -3), have been identified.
Commissural axons, which cross the midline, express low
levels of Robo; longitudinal axons, which avoid the
midline, express high levels of Robo. robo1, -2, and -3
are expressed by commissural neurons in the vertebrate
spinal cord and Slits 1, -2, -3 are expressed at the
ventral midline. Robo-3 is a divergent member of the Robo
family which instead of being a positive regulator of
slit responsiveness, antagonizes slit responsiveness in
precrossing axons. The Slit-Robo interaction is mediated
by the second leucine-rich repeat (LRR) domain of Slit
and the two N-terminal Ig domains of Robo, Ig1 and Ig2.
The primary Robo binding site for Slit2 has been shown by
surface plasmon resonance experiments and mutational
analysis to be is the Ig1 domain, while the Ig2 domain
has been proposed to harbor a weak secondary binding
site.

palladin. Ig_Palladin_C: C-terminal immunoglobulin
(Ig)-like domain of palladin. Palladin belongs to the
palladin-myotilin-myopalladin family. Proteins belonging
to this family contain multiple Ig-like domains and
function as scaffolds, modulating actin cytoskeleton.
Palladin binds to alpha-actinin ezrin,
vasodilator-stimulated phosphoprotein VASP, SPIN90 (DIP,
mDia interacting protein), and Src. Palladin also binds
F-actin directly, via its Ig3 domain. Palladin is
expressed as several alternatively spliced isoforms,
having various combinations of Ig-like domains, in a
cell-type-specific manner. It has been suggested that
palladin's different Ig-like domains may be specialized
for distinct functions.

protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. The pseudokinase domain shows similarity to

regulate cell energy metabolism and cell polarity. LKB1
is a tumor suppressor linked to the rare inherited

(PTK) family; Janus kinase 1 (Jak1); pseudokinase domain
(repeat 1). The PTKc (catalytic domain) family to which
this subfamily belongs, is part of a larger superfamily
that includes the catalytic domains of other kinases such
as protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Jak1 is a
member of the Janus kinase (Jak) subfamily of proteins,
which are cytoplasmic (or nonreceptor) tyr kinases
containing an N-terminal FERM domain, followed by a Src
homology 2 (SH2) domain, a pseudokinase domain, and a
C-terminal tyr kinase domain. The pseudokinase domain
shows similarity to tyr kinases but lacks crucial
residues for catalytic activity and ATP binding. It
modulates the kinase activity of the C-terminal catalytic
domain. Jaks are crucial for cytokine receptor signaling.
They are activated by autophosphorylation upon
cytokine-induced receptor aggregation, and subsequently
trigger downstream signaling events such as the
phosphorylation of signal transducers and activators of
transcription (STATs). Jak1 is widely expressed in many
tissues. Many cytokines are dependent on Jak1 for
signaling, including those that use the shared receptor
subunits common gamma chain (IL-2, IL-4, IL-7, IL-9,
IL-15, IL-21) and gp130 (IL-6, IL-11, oncostatin M,
G-CSF, and IFNs, among others). The many varied
interactions of Jak1 and its ubiquitous expression
suggest many biological roles. Jak1 is important in
neurological development, as well as in lymphoid
development and function. It also plays a role in the
pathophysiology of cardiac hypertrophy and heart failure.
A mutation in the ATP-binding site of Jak1 was identified
in a human uterine leiomyosarcoma cell line, resulting in
defective cytokine induction and antigen presentation,
thus allowing the tumor to evade the immune system.

Kinase, HER3. Protein Tyrosine Kinase (PTK) family; HER3
(ErbB3); pseudokinase domain. The PTKc (catalytic domain)
family to which this subfamily belongs, is part of a
larger superfamily that includes the catalytic domains of
other kinases such as protein serine/threonine kinases,
RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
HER3 is a member of the EGFR (HER, ErbB) subfamily of
proteins, which are receptor tyr kinases (RTKs)
containing an extracellular EGF-related ligand-binding
region, a transmembrane helix, and a cytoplasmic region
with a tyr kinase domain and a regulatory C-terminal
tail. Unlike other tyr kinases, phosphorylation of the
activation loop of EGFR proteins is not critical to their
activation. Instead, they are activated by ligand-induced
dimerization, leading to the phosphorylation of tyr
residues in the C-terminal tail, which serve as binding
sites for downstream signaling molecules. HER3 binds the
neuregulin ligands, NRG1 and NRG2. HER3 contains an
impaired tyr kinase domain and relies on its
heterodimerization partners for activity following ligand
binding. The HER2-HER3 heterodimer constitutes a high
affinity co-receptor capable of potent mitogenic
signaling. HER3 participates in a signaling pathway
involved in the proliferation, survival, adhesion, and
motility of tumor cells.

(roundabout) receptors. Robo receptors play a role in the
development of the central nervous system (CNS), and are
receptors of Slit protein. Slit is a repellant secreted
by the neural cells in the midline. Slit acts through
Robo to prevent most neurons from crossing the midline
from either side. Three mammalian Robo homologs (robo1,
-2, and -3), and three mammalian Slit homologs
(Slit-1,-2, -3), have been identified. Commissural axons,
which cross the midline, express low levels of Robo;
longitudinal axons, which avoid the midline, express high
levels of Robo. robo1, -2, and -3 are expressed by
commissural neurons in the vertebrate spinal cord and
Slits 1, -2, -3 are expressed at the ventral midline.
Robo-3 is a divergent member of the Robo family which
instead of being a positive regulator of slit
responsiveness, antagonizes slit responsiveness in
precrossing axons. The Slit-Robo interaction is mediated
by the second leucine-rich repeat (LRR) domain of Slit
and the two N-terminal Ig domains of Robo, Ig1 and Ig2.
The primary Robo binding site for Slit2 has been shown by
surface plasmon resonance experiments and mutational
analysis to be is the Ig1 domain, while the Ig2 domain
has been proposed to harbor a weak secondary binding
site.

binding involves Ig1, Ig2, and Ig3. By this model, Ig1
and Ig2 mediate dimerization of NCAM molecules situated

domains mediate interactions between NCAM molecules
expressed on the surface of opposing cells (trans

Tyrosine Kinase, Tyrosine kinase 2. Protein Tyrosine
Kinase (PTK) family; Tyrosine kinase 2 (Tyk2);
pseudokinase domain (repeat 1). The PTKc (catalytic
domain) family to which this subfamily belongs, is part
of a larger superfamily that includes the catalytic
domains of other kinases such as protein serine/threonine
kinases, RIO kinases, and phosphoinositide 3-kinase
(PI3K). PTKs catalyze the transfer of the
gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. Tyk2 is a member of the
Janus kinase (Jak) subfamily of proteins, which are
cytoplasmic (or nonreceptor) tyr kinases containing an
N-terminal FERM domain, followed by a Src homology 2
(SH2) domain, a pseudokinase domain, and a C-terminal tyr
kinase domain. The pseudokinase domain shows similarity
to tyr kinases but lacks crucial residues for catalytic
activity and ATP binding. It modulates the kinase
activity of the C-terminal catalytic domain. Jaks are
crucial for cytokine receptor signaling. They are
activated by autophosphorylation upon cytokine-induced
receptor aggregation, and subsequently trigger downstream
signaling events such as the phosphorylation of signal
transducers and activators of transcription (STATs). Tyk2
is widely expressed in many tissues. It is involved in
signaling via the cytokine receptors IFN-alphabeta, IL-6,
IL-10, IL-12, IL-13, and IL-23. It mediates cell surface
urokinase receptor (uPAR) signaling and plays a role in
modulating vascular smooth muscle cell (VSMC) functional
behavior in response to injury. Tyk2 is also important in
dendritic cell function and T helper (Th)1 cell
differentiation. A homozygous mutation of Tyk2 was found
in a patient with hyper-IgE syndrome (HIES), a primary
immunodeficiency characterized by recurrent skin
abscesses, pneumonia, and elevated serum IgE. This
suggests that Tyk2 may play important roles in multiple
cytokine signaling involved in innate and adaptive
immunity.

>gnl|CDD|241265 cd01231, PH_SH2B_family, SH2B adapter protein 1, 2, and 3 Pleckstrin
homology (PH) domain. SH2B family/APS proteins are a
family of intracellular adaptor proteins that influences
a variety of signaling pathways mediated by Janus kinase
(JAK) and receptor tyrosine kinases (RTKs) including
receptors for insulin, insulin-like growth factor-1,
Janus kinase 2 (Jak2), platelet derived growth factor,
fibroblast growth factor and nerve growth factor. They
function in glucose homeostasis, energy metabolism,
hematopoesis and reproduction. Mutations in human SH2B
orthologs are associated with metabolic disregulation and
obesity. There are several SH2B members in mammals: SH2B1
(splice variants: SH2B1alpha, SH2B1beta, SH2B1gamma, and
SH2B1delta), SH2B2 (APS) and SH2B3 (Lnk). They contain a
PH domain, a SH2 domain, a proline rich region, multiple
consensus sites for tyrosine and serine/threonine
phosphorylation and a highly conserved c-Cbl recognition
motif. These domains function as protein-protein
interaction motifs which allows SH2B proteins to
integrate and transduce intracellular signals from
multiple signaling networks in the absence of intrinsic
catalytic activity. SH2B proteins bind via their SH2
domains to phosphotyrosine residues within the
intracellular tails of several activated RTKs thereby
contributing to receptor activation. SH2B proteins have
been shown to interact with insulin receptor substrates
IRS1 and IRS2, Grb2, Shc and c-Cbl which may or may not
require RTK-stimulated tyrosine phosphorylation of SH2B.
positively and negatively regulating RTK signaling.
Understanding the physiological functions of SH2B
proteins in mammals has been complicated by the presence
of multiple SH2B isoforms and conflicting data. Both
SH2-Bbeta and APS associate with JAKs, but the former
facilitates JAK/STAT signaling while the latter inhibits
it. Lnk plays a role in cell growth and proliferation
with mutations resulting in growth reduction,
developmental delay and female sterility. Recently Lnk
Drosophila has been shown to be an important regulator of
the insulin/insulin-like growth factor (IGF)-1 signaling
(IIS) pathway during growth. PH domains have diverse
functions, but in general are involved in targeting
proteins to the appropriate cellular location or in the
interaction with a binding partner. They share little
sequence conservation, but all have a common fold, which
is electrostatically polarized. Less than 10% of PH
domains bind phosphoinositide phosphates (PIPs) with high
affinity and specificity. PH domains are distinguished
from other PIP-binding domains by their specific
high-affinity binding to PIPs with two vicinal phosphate
groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3
which results in targeting some PH domain proteins to the
plasma membrane. A few display strong specificity in
lipid binding. Any specificity is usually determined by
loop regions or insertions in the N-terminus of the
domain, which are not conserved across all PH domains. PH
domains are found in cellular signaling proteins such as
serine/threonine kinase, tyrosine kinases, regulators of
G-proteins, endocytotic GTPases, adaptors, as well as
cytoskeletal associated molecules and in lipid associated
enzymes.

Ig2_IL1R_like: domain similar to the second
immunoglobulin (Ig)-like domain of interleukin-1 receptor

a transmembrane domain, and a large cytoplasmic domain.
Mature IL1R2 is organized similarly except that it has a

signal transduction. A naturally occurring cytokine
IL-1RA (IL-1 receptor antagonist) is widely expressed and
binds to IL-1 receptors, inhibiting the binding of IL-1
