>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.

>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, cAMP-dependent protein kinase. Serine/Threonine
Kinases (STKs), cAMP-dependent protein kinase (PKA)
subfamily, catalytic (c) subunit. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The PKA
subfamily is part of a larger superfamily that includes

phosphotransferase, choline kinase, and phosphoinositide
3-kinase (PI3K). This subfamily is composed of the
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.

>gnl|CDD|173663 cd05572, STKc_cGK_PKG, Catalytic domain of the Protein
Serine/Threonine Kinase, cGMP-dependent protein kinase.
Serine/Threonine Kinases (STKs), cGMP-dependent protein
kinase (cGK or PKG) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
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.

Kinases (STKs), Microtubule-associated serine/threonine
(MAST) kinase subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from

The MAST kinase 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. The MAST kinase subfamily
includes MAST kinases, MAST-like (MASTL) kinases, and
fungal kinases with similarity to Saccharomyces
cerevisiae Rim15 and Schizosaccharomyces pombe cek1. MAST
kinases contain an N-terminal domain of unknown function,
a central catalytic domain, and a C-terminal PDZ domain
that mediates protein-protein interactions. MASTL kinases
carry only a catalytic domain which contains a long
insert relative to other kinases. The fungal kinases in
this subfamily harbor other domains in addition to a
central catalytic domain, which also contains an insert
relative to MAST kinases like MASTL. Rim15 contains a
C-terminal signal receiver (REC) domain while cek1
contains an N-terminal PAS domain. MAST kinases are
cytoskeletal associated kinases of unknown function that
are also expressed at neuromuscular junctions and
postsynaptic densities. The fungal proteins Rim15 and
cek1 are involved in the regulation of meiosis and
mitosis, respectively.

Serine/Threonine Kinases (STKs),
Phosphoinositide-dependent kinase 1 (PDK1) subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The PDK1 subfamily is

carries an N-terminal catalytic domain and a C-terminal
pleckstrin homology (PH) domain that binds
phosphoinositides. It phosphorylates the activation loop
of AGC kinases that are regulated by PI3K such as PKB,
SGK, and PKC, among others, and is crucial for their
activation. Thus, it contributes in regulating many
processes including metabolism, growth, proliferation,
and survival. PDK1 also has the ability to
autophosphorylate and is constitutively active in
mammalian cells. PDK1 is essential for normal embryo
development and is important in regulating cell volume.

the catalytic domains of other protein STKs, protein

responses to extracellular signals. They control critical
cellular functions including differentiation,
proliferation, migration, and apoptosis. They are also
implicated in the pathogenesis of many diseases including
multiple types of cancer, stroke, diabetes, and chronic
inflammation. Typical MAPK pathways involve a triple
kinase core cascade comprising of the MAPK, which is
phosphorylated and activated by a MAPK kinase (MAP2K or
MKK), which itself is phosphorylated and activated by a
MAPK kinase kinase (MAP3K or MKKK). Each 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.
There are three main typical MAPK subfamilies:
Extracellular signal-Regulated Kinase (ERK), c-Jun
N-terminal Kinase (JNK), and p38. Some MAPKs are atypical
in that they are not regulated by MAP2Ks. These include
MAPK4, MAPK6, NLK, and ERK7.

prevented from entering mitosis. Neks contain a conserved
N-terminal catalytic domain and a more divergent
C-terminal regulatory region of various sizes and

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.

Protein kinases (PKs), MAP kinase kinase (MAPKK)
subfamily, Plant MAPKKs and similar proteins, catalytic
(c) domain. PKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine or

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.

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.

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.

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
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. The Nek2 subfamily
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.

They regulate cell growth, cell proliferation, and cell

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.

important roles during meiosis. MAK is highly expressed
in testicular cells specifically in the meiotic phase,
but is not essential for spermatogenesis and fertility.
It functions as a coactivator of the androgen receptor in
prostate cells. MRK, also called Intestinal Cell Kinase
(ICK), is expressed ubiquitously, with highest expression
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
development of many organs. MAK and MRK may be involved
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 (STKs), Mitogen-Activated
Protein Kinase 15 (MAPK15) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine

part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline

important mediators of cellular responses to
extracellular signals. Human MAPK15 is also called
Extracellular signal Regulated Kinase 8 (ERK8) while the
rat protein is called ERK7. ERK7 and ERK8 display both
similar and different biochemical properties. They
autophosphorylate and activate themselves and do not
require upstream activating kinases. ERK7 is
constitutively active and is not affected by
extracellular stimuli whereas ERK8 shows low basal
activity and is activated by DNA-damaging agents. ERK7
and ERK8 also have different substrate profiles. Genome
analysis shows that they are orthologs with similar gene
structures. ERK7 and ERK 8 may be involved in the
signaling of some nuclear receptor transcription factors.
ERK7 regulates hormone-dependent degradation of estrogen
receptor alpha while ERK8 down-regulates the
transcriptional co-activation androgen and glucocorticoid
receptors.

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.

The p38 subfamily is part of a larger superfamily that

kinases (MAPKs), serving as important mediators of
cellular responses to extracellular signals. They
function in the regulation of the cell cycle, cell
development, cell differentiation, senescence,
tumorigenesis, apoptosis, pain development and pain
progression, and immune responses. p38 kinases 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. p38 substrates
include other protein kinases and factors that regulate
transcription, nuclear export, mRNA stability and
translation. p38 kinases are drug targets for the
inflammatory diseases psoriasis, rheumatoid arthritis,
and chronic pulmonary disease. Vertebrates contain four
isoforms of p38, named alpha, beta, gamma, and delta,
which show varying substrate specificity and expression
patterns. p38alpha and p38beta are ubiquitously
expressed, p38gamma is predominantly found in skeletal
muscle, and p38delta is found in the heart, lung, testis,
pancreas, and small intestine.

activates CDK5. CDK7 is also a component of the general
transcription factor TFIIH, which phosphorylates the
C-terminal domain (CTD) of RNA polymerase II when it is
bound with unphosphorylated DNA, as present in the
pre-initiation complex. Following phosphorylation, the
CTD dissociates from the DNA which allows transcription

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.

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.

involved in the formation of primary cilium and in the
maintenance of centrosomes. It cycles through the nucleus
and may be capable of relaying signals between the cilium
and the nucleus. Nek1 is implicated in the development of
polycystic kidney disease, which is characterized by
benign polycystic tumors formed by abnormal overgrowth of

Serine/Threonine Kinases (STKs), Rho-associated
coiled-coil containing protein kinase (ROCK) and Nuclear
Dbf2-Related (NDR)-like kinase subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The ROCK- and NDR-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. Members of this subfamily include ROCK and
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
(NTR) domain and an insert within the catalytic domain
that contains an auto-inhibitory sequence. Proteins in
this subfamily are involved in regulating many cellular
functions including contraction, motility, division,
proliferation, apoptosis, morphogenesis, and cytokinesis.

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).

>gnl|CDD|173668 cd05577, STKc_GRK, Catalytic domain of the Protein Serine/Threonine
Kinase, G protein-coupled Receptor Kinase.
Serine/Threonine Kinases (STKs), G protein-coupled
Receptor Kinase (GRK) subfamily, 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. GRKs contain a central catalytic
domain, flanked by N- and C-terminal extensions. The
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.

Serine/Threonine Kinases (STKs), Mitogen-Activated
Protein Kinase 4 (MAPK4) and MAPK6 subfamily, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAPK4/6 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. MAPK4 is also called ERK4 or
p63MAPK, while MAPK6 is also called ERK3 or p97MAPK.
MAPK4 and MAPK6 are atypical MAPKs that are not regulated
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.

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.

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.

Serine/Threonine Kinase, Novel Protein Kinase C theta.
Serine/Threonine Kinases (STKs), Novel Protein Kinase C
(nPKC), theta isoform, catalytic (c) domain. STKs
catalyze 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 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.

stress-activated kinase (MSK) subfamily, MSK1, N-terminal
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MSK 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. MSKs contain an
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. MSK1 plays a role in
the regulation of translational control and
transcriptional activation. It phosphorylates the
transcription factors, CREB and NFkappaB. It also
phosphorylates the nucleosomal proteins H3 and HMG-14.
Increased phosphorylation of MEK1 is associated with the
development of cerebral ischemic/hypoxic preconditioning.

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.

mediators of cellular responses to extracellular signals.
Sty1 and Hog1 are stress-activated MAPKs that partipate
in transcriptional regulation in response to stress. Sty1
is activated in response to oxidative stress, osmotic
stress, and UV radiation. Sty1 is regulated by the MAP2K
Wis1, which is activated by the MAP3Ks Wis4 and Win1,
which receive signals of the stress condition from
membrane-spanning histidine kinases Mak1-3. Activated
Sty1 stabilizes the Atf1 transcription factor and induces
transcription of Atf1-dependent genes of the core
environmetal stress response (CESR). Hog1 is the key
element in the high osmolarity glycerol (HOG) pathway and
is activated upon hyperosmotic stress. Activated Hog1
accumulates in the nucleus and regulates stress-induced
transcription. The HOG pathway is mediated by two
transmembrane osmosensors, Sln1 and Sho1.

The PAK subfamily is part of a larger superfamily that

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.
Group II PAKs, also called non-conventional PAKs, include
PAK4, PAK5, and PAK6. Group II PAKs contain PBD
(p21-binding domain) and catalytic domains, but lack
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.

Kinase, Microtubule-associated serine/threonine kinase.
Serine/Threonine Kinases (STKs), Microtubule-associated
serine/threonine (MAST) kinase subfamily, MAST, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAST kinase 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. MAST
kinases contain an N-terminal domain of unknown function,
a central catalytic domain, and a C-terminal PDZ domain
that mediates protein-protein interactions. There are
four mammalian MAST kinases, named MAST1-MAST4. MAST1 is
also referred to as syntrophin-associated STK (SAST),
while MAST2 is also called MAST205. MAST kinases are
cytoskeletal associated kinases of unknown function that
are also expressed at neuromuscular junctions and
postsynaptic densities. MAST1, MAST2, and MAST3 bind and
phosphorylate the tumor suppressor PTEN, and may
contribute to the regulation and stabilization of PTEN.
MAST2 is involved in the regulation of the Fc-gamma
receptor of the innate immune response in macrophages,
and may also be involved in the regulation of the Na+/H+
exchanger NHE3.

phosphoinositide 3-kinase. This 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.

biochemical and structural features. PAK6 belongs to
group II. Group II PAKs contain a PBD (p21-binding
domain) and a C-terminal catalytic domain, but do not
harbor an AID (autoinhibitory domain) or SH3 binding
sites. PAK6 may play a role in stress responses through
its activation by the mitogen-activated protein kinase
(MAPK) p38 and MAPK kinase 6 (MKK6) pathway. PAK6 is
highly expressed in the brain. It is not required for
viability, but together with PAK5, it is required for
normal levels of locomotion and activity, and for
learning and memory. Increased expression of PAK6 is
found in primary and metastatic prostate cancer. PAK6 may
play a role in the regulation of motility.

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.

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.

Members of this group include the MAPKKs Pek1/Skh1 from
Schizosaccharomyces pombe and MKK2 from Saccharomyces

activated by multiple stress conditions, and is essential
in cell wall construction, morphogenesis, cytokinesis,
and ion homeostasis.

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

(PH) domain. Protein Kinase C family is composed of
three members, PKD1 (PKCmu), PKD2 and PKD3 (PKCnu). Like
the C-type protein kinases (PKCs), PKDs are activated by
diacylglycerol (DAG). They are involved in vesicular
transport, cell proliferation, survival, migration and
immune responses. PKD consists of tandem C1 domains,
followed by a PH domain and a kinase domain. While the
PKD PH domain has not been shown to bind phosphorylated
inositol lipids and is not required for membrane
translocation, it is required for nuclear export. 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.

Serine/Threonine Kinases (STKs), Novel Protein Kinase C
(nPKC), delta isoform, catalytic (c) domain. STKs
catalyze 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 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-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.

biological processes such as respiration, iron
transport, oxidative stress protection, hormone

of high-affinity copper transport proteins (Ctr
proteins) mediates copper uptake at the plasma membrane.
A series of clustered methionine residues in the
hydrophilic extracellular domain, and an MXXXM motif in
the second transmembrane domain, are important for
copper uptake. These methionine probably coordinate
copper during the process of metal transport.

Serine/Threonine Kinases (STKs), Cyclin-dependent protein
kinase 2 (CDK2) and CDK3 subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The CDK2/3 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. CDKs 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. 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.

kinases (STKs), p21-activated kinase (PAK) subfamily,
Group I, catalytic (c) domain. STKs catalyze the transfer
of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The PAK
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. PAKs are Rho family GTPase-regulated kinases
that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs are
implicated in the regulation of many cellular processes
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.

GRK1 to GRK7. GRK5 is widely expressed in many tissues.
It associates with the membrane though an N-terminal PIP2

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.

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.

Receptor Kinase (GRK) subfamily, GRK1 isoform, catalytic

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

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. 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
inherited form of stationary nightblindness called Oguchi
disease.

myosin-like Protein Serine/Threonine Kinases.
Serine/threonine kinases (STKs), Class III myosin-like
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-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. Class III myosins are motor
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)
and MAPKKKK6 (or MAP4K6). MAP4Ks are involved in some
MAPK signaling pathways 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.
MAPK signaling cascades are important in mediating
cellular responses to extracellular signals.

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.

The nPKC subfamily is part of a larger superfamily that

(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-epsilon has been shown to
behave as an oncoprotein. Its overexpression contributes
to neoplastic transformation depending on the cell type.
It contributes to oncogenesis by inducing disordered cell
growth and inhibiting cell death. It also plays a role in
tumor invasion and metastasis. PKC-epsilon has also been
found to confer cardioprotection against ischemia and
reperfusion-mediated damage. Other cellular functions
include the regulation of gene expression, cell adhesion,
and cell motility.

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.

Protein Kinase. Serine/Threonine Kinases (STKs),
p38alpha subfamily, catalytic (c) domain. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
p38alpha 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. p38alpha, also called MAPK14, is expressed in most
tissues and is the major isoform involved in the immune
and inflammatory response. It is the central p38 MAPK
involved in myogenesis. It plays a role in regulating
cell cycle check-point transition and promoting cell
differentiation. p38alpha also regulates cell
proliferation and death through crosstalk with the JNK
pathway. Its substrates include MAPK activated protein
kinase 2 (MK2), MK5, and the transcription factors ATF2
and Mitf.

Kinase C (cPKC) subfamily, beta isoforms, catalytic (c)
domain. STKs catalyze the transfer of the

residues on protein substrates. The cPKC 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.
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.

into two groups (I and II), according to their
biochemical and structural features. PAK4 belongs to
group II. Group II PAKs contain a PBD (p21-binding
domain) and a C-terminal catalytic domain, but do not
harbor an AID (autoinhibitory domain) or SH3 binding
sites. PAK4 regulates cell morphology and cytoskeletal
organization. It is essential for embryonic viability and
proper neural development. Mice lacking PAK4 die due to
defects in the fetal heart. In addition, their spinal
cord motor neurons showed failure to differentiate and
migrate. PAK4 also plays a role in cell survival and
tumorigenesis. It is overexpressed in many primary tumors
including colon, esophageal, and mammary tumors. PAK4 has
also been implicated in viral and bacterial infection
pathways.

Saccharomyces cerevisiae and Cryptococcus neoformans
Ste11, and related proteins. They contain an N-terminal
SAM (sterile alpha-motif) domain, which mediates
protein-protein interaction, and a C-terminal catalytic
domain. 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. Fission yeast Byr2 is regulated by
Ras1. It responds to pheromone signaling and controls
mating through the MAPK pathway. Budding yeast Ste11
functions in MAPK cascades that regulate mating, high
osmolarity glycerol, and filamentous growth responses.

transcription, and neuronal function. CDK9 together with
a cyclin partner (cyclin T1, T2a, T2b, or K) is the main
component of distinct positive transcription elongation
factors (P-TEFb), which function as Ser2 C-terminal
domain kinases of RNA polymerase II. P-TEFb participates
in multiple steps of gene expression including
transcription elongation, mRNA synthesis, processing,
export, and translation. It also plays a role in
mediating cytokine induced transcription networks such as
IL6-induced STAT3 signaling. In addition, the CDK9/cyclin
T2a complex promotes muscle differentiation and enhances
the function of some myogenic regulatory factors.

Vetebrates harbor three different JNK genes (Jnk1, Jnk2,

to a lesser extent in the heart and testis. Mice
deficient in Jnk3 are protected against kainic
acid-induced seizures, stroke, sciatic axotomy neural
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
pathogenesis of these diseases.

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.

Serine/Threonine Kinases (STKs), G protein-coupled
Receptor Kinase (GRK) subfamily, beta-adrenergic receptor
kinase (beta-ARK) group, 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. 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.

DMPK-like subfamily is composed of DMPK and DMPK-related
cell division control protein 42 (Cdc42) binding kinase
(MRCK). Three isoforms of MRCK are known, named alpha,
beta and gamma. The DMPK gene is implicated in myotonic
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
and homeostasis of calcium. MRCK is activated via
interaction with the small GTPase Cdc42. MRCK/Cdc42
signaling mediates myosin-dependent cell motility.
MRCKgamma is expressed in heart and skeletal muscles,
unlike MRCKalpha and MRCKbeta, which are expressed
ubiquitously.

Serine/Threonine Kinases (STKs), Never In Mitosis gene A
(NIMA)-related kinase 6 (Nek6) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The Nek6 subfamily is one
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. Nek6 is required
for the transition from metaphase to anaphase. It also
plays important roles in mitotic spindle formation and
cytokinesis. Activated by Nek9 during mitosis, Nek6
phosphorylates Eg5, a kinesin that is important for
spindle bipolarity. Nek6 localizes to spindle
microtubules during metaphase and anaphase, and to the
midbody during cytokinesis.

is activated via interaction with Rho GTPases. ROCK2 was
the first identified target of activated RhoA, and was
found to play a role in stress fiber and focal adhesion
formation. It is prominently expressed in the brain,
heart, and skeletal muscles. It is implicated in vascular
and neurological disorders, such as hypertension and
vasospasm of the coronary and cerebral arteries. ROCK2 is
also activated by caspase-2 cleavage, resulting in
thrombin-induced microparticle generation in response to
cell activation. Mice deficient in ROCK2 show
intrauterine growth retardation and embryonic lethality
because of placental dysfunction.

p38beta, p38gamma is insensitive to pyridinylimidazoles.
It displays an antagonizing function compared to
p38alpha. p38gamma inhibits, while p38alpha stimulates,
c-Jun phosphorylation and AP-1 mediated transcription.
p38gamma also plays a role in the signaling between Ras

Xenopus, p38gamma is critical in the meiotic maturation
of oocytes.

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. GRK6 is widely expressed in many tissues. t
is expressed as multiple splice variants with different
domain architectures. It is post-translationally
palmitoylated and localized in the membrane. GRK6 plays
important roles in the regulation of dopamine, M3

also plays maladaptive roles in addiction and Parkinson's
disease. GRK6-deficient mice exhibit altered dopamine
receptor regulation, decreased lymphocyte chemotaxis, and
increased acute inflammation and neutrophil chemotaxis.

Protein Kinase C (cPKC) subfamily, alpha isoform,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The cPKC 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.
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.

Serine/threonine kinases (STKs), Apoptosis
signal-regulating kinase (ASK) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
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,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. Subfamily members
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.

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). PAK1 is important in the regulation of
many cellular processes including cytoskeletal dynamics,
cell motility, growth, and proliferation. Although PAK1
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.

>gnl|CDD|173720 cd05631, STKc_GRK4, Catalytic domain of the Protein Serine/Threonine
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.

kinases, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
Jak subfamily proteins 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
catalytic domain. Most Jaks are expressed in a wide
variety of tissues, except for Jak3, which is expressed
only in hematopoietic cells. 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).
Jaks are also involved in regulating the surface
expression of some cytokine receptors. The Jak-STAT
pathway is involved in many biological processes
including hematopoiesis, immunoregulation, host defense,
fertility, lactation, growth, and embryogenesis.

(MAPK) kinase kinase (MAPKKK or MKKK or MAP3K), that
phosphorylates and activates the MAPK kinase MEK5 (or
MKK5), which in turn phosphorylates and 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. In addition, MEKK3 is
involved in interleukin-1 receptor and Toll-like receptor
4 signaling. It is also a specific regulator of the
proinflammatory cytokines IL-6 and GM-CSF in some immune
cells. MEKK3 also regulates calcineurin, which plays a
critical role in T cell activation, apoptosis, skeletal
myocyte differentiation, and cardiac hypertrophy.

MAPKKKKs) are involved in 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. 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.

as protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to

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

choline kinase, and phosphoinositide 3-kinase. The
mitogen-activated protein (MAP) kinase signaling pathways
are important mediators of cellular responses to

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

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.

Kinase (PTK) family; Interleukin-2 (IL-2)-inducible
T-cell kinase (Itk); 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. Itk (also
known as Tsk or Emt) is a member 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, Itk
contains the Tec homology (TH) domain containing one
proline-rich region and a zinc-binding region. Tec
kinases are expressed mainly by haematopoietic cells. Itk
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
C-gamma1 activation and actin polymerization. It also
plays a role in the downstream signaling of the T-cell
costimulatory receptor CD28, the T-cell surface receptor
CD2, and the chemokine receptor CXCR4. In addition, Itk
is crucial for the development of T-helper(Th)2 effector
responses.

contains an N-terminal regulatory (NTR) domain and an
insert within the catalytic domain that contains an
auto-inhibitory sequence. Like many other AGC kinases,
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
called STK38.

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.

kinase expressed in hepatocellular carcinoma (Tec)
subfamily; catalytic (c) domain. The Tec subfamily is
composed of Tec, Btk, Bmx (Etk), Itk (Tsk, Emt), Rlk
(Txk), 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. Tec
kinases are cytoplasmic (or nonreceptor) tyr kinases
(nRTKs) 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, 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).

in cell growth and differentiation, angiogenesis,
inflammation and immunity, and cytoskeletal regulation. A
recent study implicates Fes kinase as a tumor suppressor
in colorectal cancer.

family; Src-related kinase lacking C-terminal regulatory
tyrosine and N-terminal myristylation sites (Srm) and

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. Srm and
Brk are a member of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases in general 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). Srm and
Brk however, lack the N-terminal myristylation sites.
Src proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Brk has been found to be overexpressed
in a majority of breast tumors.

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. Abl (or
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.

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

Protein Tyrosine Kinase (PTK) family; Janus kinase 2

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. Jak2 and
Jak3 are members 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).

cyclins. Together, they are involved in the control of
cell-cycle progression, transcription, and neuronal
function. CDC2L6 is also called CDK8-like and was
previously referred to as CDK11. However, this is a
confusing nomenclature as CDC2L6 is distinct from
CDC2L1, which is represented by the two protein products
from its gene, called CDK11(p110) and CDK11(p58), as
well as the caspase-processed CDK11(p46). CDK11(p110),
CDK11(p58), and CDK11(p46)do not belong to this
subfamily. CDC2L6 is an associated protein of Mediator,
a multiprotein complex that provides a platform to
connect transcriptional and chromatin regulators and
cofactors, in order to activate and mediate RNA
polymerase II transcription. CDC2L6 is localized mainly
in the nucleus amd exerts an opposing effect to CDK8 in
VP16-dependent transcriptional activation by being a
negative regulator.

kinase kinase kinase kinase 5. Serine/threonine kinases
(STKs), mitogen-activated protein kinase (MAPK) kinase
kinase kinase 5 (MAPKKKK5 or MAP4K5) subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAP4K5 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. Members of this
subfamily 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. MAP4K5, also called germinal
center kinase-related enzyme (GCKR), has been shown to
activate the MAPK c-Jun N-terminal kinase (JNK). MAP4K5
also facilitates Wnt signaling in B cells, and may
therefore be implicated in the control of cell fate,
proliferation, and polarity.

serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to

subfamily kinases are cytoplasmic (or nonreceptor) tyr
kinases containing two Src homology 2 (SH2) domains
N-terminal to the catalytic tyr kinase domain. They are
involved in the signaling downstream of activated
receptors (including B-cell, T-cell, and Fc receptors)
that contain ITAMs (immunoreceptor tyr activation
motifs), leading to processes such as cell proliferation,
differentiation, survival, adhesion, migration, and
phagocytosis. Syk is important in B-cell receptor (BCR)
signaling, while Zap-70 is primarily expressed in T-cells
and NK cells, and is a crucial component in T-cell
receptor (TCR) signaling. Syk also plays a central role
in Fc receptor-mediated phagocytosis in the adaptive
immune system. Shark is exclusively expressed in
ectodermally derived epithelia, and is localized
preferentially to the apical surface of the epithelial
cells, it may play a role in a signaling pathway for
epithelial cell polarity.

gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. 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. 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.

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).

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

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.

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. 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
activation motifs) in CD19 and in Ig components of BCR.
It negatively regulates signaling by its unique ability
to phosphorylate ITIMs (immunoreceptor tyr inhibition
motifs) in cell surface receptors like CD22 and CD5. Lyn
also plays an important role in G-CSF receptor signaling
by phosphorylating a variety of adaptor molecules.

Tyrosine Kinase (PTK) family; Tyrosine kinase expressed
in hepatocellular carcinoma (Tec) and Resting lymphocyte
kinase (Rlk); 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. Tec and Rlk (also named
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.

It then phosphorylates target proteins, which propagate
the signals to downstream pathways. Zap-70 is hardly
detected in normal peripheral B-cells, but is present in
some B-cell malignancies. It is used as a diagnostic
marker for chronic lymphocytic leukemia (CLL) as it is
associated with the more aggressive subtype of the
disease.

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.

kinases (STKs), thousand-and-one amino acids 1 (TAO1)
subfamily, catalytic (c) domain. STKs catalyze the

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. TAO proteins possess mitogen-activated protein
kinase (MAPK) kinase kinase (MAPKKK or MAP3K or MKKK)
activity. MAPK signaling cascades are important in
mediating cellular responses to extracellular signals.
TAO1 is sometimes referred to as prostate-derived sterile
20-like kinase 2 (PSK2). TAO1 activates the p38 MAPK
through direct interaction with and activation of MEK3.
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.

EphA4, which also binds ephrins-B2/B3. EphRs contain an
ephrin-binding domain and two fibronectin repeats
extracellularly, a transmembrane segment, and a

ligand to EphR requires cell-cell contact since both are
anchored to the plasma membrane. The resulting downstream

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

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.

similar proteins. The PTKc family is part of a larger

catalyze the transfer of the gamma-phosphoryl group from

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.

containing an extracellular ligand-binding region with
seven immunoglobulin (Ig)-like domains, a transmembrane
segment, and an intracellular catalytic domain. In
VEGFR3, the fifth Ig-like domain is replaced by a
disulfide bridge. The binding of VEGFRs to their ligands,
the VEGFs, leads to receptor dimerization, activation,
and intracellular signaling. There are five VEGF ligands
in mammals, which bind, in an overlapping pattern to the

regulate the cardiovascular system. They are critical for
vascular development during embryogenesis and blood
vessel formation in adults. They induce cellular
functions common to other growth factor receptors such as

non-receptor) tyr kinases which are anchored to the
plasma membrane. They 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. They were identified as the first
proto-oncogene products, and they regulate cell
adhesion, invasion, and motility in cancer cells and
tumor vasculature, contributing to cancer progression
and metastasis. Src kinases are overexpressed in a
variety of human cancers, making them attractive targets
for therapy. They are also implicated in acute
inflammatory responses and osteoclast function. Src,
Fyn, Yes, and Yrk are widely expressed, while Blk, Lck,
Hck, Fgr, and Lyn show a limited expression pattern.

domain. The STRAD subfamily is part of a larger
superfamily that includes the catalytic domains of
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.

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

together with Zap-70, form the Syk subfamily of kinases
which are cytoplasmic (or nonreceptor) tyr kinases
containing two Src homology 2 (SH2) domains N-terminal to
the catalytic tyr kinase domain. Syk was first cloned
from the spleen, and its function in hematopoietic cells
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,
migration, and phagocytosis. More recently, Syk
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).

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.

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. Lck is expressed in 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.

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.

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,

important role in mammalian neural development as well as
visceral muscle differentiation in Drosophila. ALK is
aberrantly expressed as fusion proteins, due to
chromosomal translocations, in about 60% of anaplastic

also found in rare cases of diffuse large B cell
lymphomas (DLBCLs). LTK is mainly expressed in B
lymphocytes and neuronal tissues. It is important in cell
proliferation and survival. Transgenic mice expressing
TLK display retarded growth and high mortality rate. In
addition, a polymorphism in mouse and human LTK is
implicated in the pathogenesis of systemic lupus

containing an extracellular ligand-binding region with
seven immunoglobulin (Ig)-like domains, a transmembrane
segment, and an intracellular catalytic domain. In
VEGFR3, the fifth Ig-like domain is replaced by a

the VEGFs, leads to receptor dimerization, activation,
and intracellular signaling. VEGFR3 preferentially binds
the ligands VEGFC and VEGFD. VEGFR3 is essential for
lymphatic endothelial cell (EC) development and function.
It has been shown to regulate adaptive immunity during
corneal transplantation. VEGFR3 is upregulated on blood
vascular ECs in pathological conditions such as vascular
tumors and the periphery of solid tumors. It plays a role

Serine/Threonine Kinase, Large Tumor Suppressor 2.
Serine/Threonine Kinases (STKs), Large Tumor Suppressor
(LATS) subfamily, LATS2 isoform, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The LATS 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. LATS functions as a tumor
suppressor and is implicated in cell cycle regulation.
LATS2 is an essential mitotic regulator responsible for
coordinating accurate cytokinesis completion and
governing the stabilization of other mitotic regulators.
It is also critical in the maintenance of proper
chromosome number, genomic stability, mitotic fidelity,
and the integrity of centrosome duplication.
Downregulation of LATS2 is associated with poor
prognosis in acute lymphoblastic leukemia and breast
cancer.

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 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.

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.

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

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

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. FGFR2 is
part of the FGFR 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. There are many splice
variants of FGFR2 which show differential expression and
binding to FGF ligands. Disruption of either FGFR2 or
FGFR2b is lethal in mice, due to defects in the placenta
or severe impairment of tissue development including
lung, limb, and thyroid, respectively. Disruption of
FGFR2c in mice results in defective bone and skull
development. Genetic alterations of FGFR2 are associated
with many human skeletal disorders including Apert
syndrome, Crouzon syndrome, Jackson-Weiss syndrome, and
Pfeiffer syndrome.

proteins are orphan receptor tyr kinases (RTKs)
containing an extracellular region with

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. Avian Ror1 was found to be
involved in late limb development. Studies in mice reveal
that Ror1 is important in the regulation of neurite
growth in central neurons, as well as in respiratory
development. Loss of Ror1 also enhances the heart and

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. Ligands for
EGFR include EGF, heparin binding EGF-like growth factor
(HBEGF), epiregulin, amphiregulin, TGFalpha, and
betacellulin. Upon ligand binding, EGFR can form homo- or
heterodimers with other EGFR subfamily members. The EGFR
signaling pathway is one of the most important pathways
regulating cell proliferation, differentiation, survival,
and growth. Overexpression and mutation in the kinase
domain of EGFR have been implicated in the development
and progression of a variety of cancers. A number of
monoclonal antibodies and small molecule inhibitors have
been developed that target EGFR, including the antibodies
Cetuximab and Panitumumab, which are used in combination
with other therapies for the treatment of colorectal
cancer and non-small cell lung carcinoma (NSCLC). The
small molecule inhibitors Gefitinib (Iressa) and
Erlotinib (Tarceva), already used for NSCLC, are
undergoing clinical trials for other types of cancer
including gastrointestinal, breast, head and neck, and
bladder.

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).

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.

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

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

Tie1 is a receptor tyr kinase (RTK) containing an
extracellular region, a transmembrane segment, and an
intracellular catalytic domain. The extracellular region
contains an immunoglobulin (Ig)-like domain, three
epidermal growth factor (EGF)-like domains, a second
Ig-like domain, and three fibronectin type III repeats.
Tie receptors are specifically expressed in endothelial
cells and hematopoietic stem cells. No specific ligand
has been identified for Tie1, although the angiopoietin,
Ang-1, binds to Tie1 through integrins at high
concentrations. In vivo studies of Tie1 show that it is
critical in vascular development.

alpha 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 alpha forms homodimers or heterodimers
with PDGFR beta, depending on the nature of the PDGF
ligand. PDGF-AA, PDGF-AB, and PDGF-CC induce PDGFR alpha
homodimerization. PDGFR signaling plays many roles in
normal embryonic development and adult physiology. PDGFR
alpha signaling is important in the formation of lung
alveoli, intestinal villi, mesenchymal dermis, and hair
follicles, as well as in the development of
oligodendrocytes, retinal astrocytes, neural crest cells,
and testicular cells. Aberrant PDGFR alpha expression is
associated with some human cancers. Mutations in PDGFR
alpha have been found within a subset of gastrointestinal
stromal tumors (GISTs). An active fusion protein
FIP1L1-PDGFR alpha, derived from interstitial deletion,
is associated with idiopathic hypereosinophilic syndrome
(HES) and chronic eosinophilic leukemia (CEL).

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.

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). EphA10, which contains an inactive tyr kinase
domain, may function to attenuate signals of co-clustered
active receptors. EphA10 is mainly expressed in the
testis. Ephrin/EphR interaction 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.

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.

is a member of the Axl subfamily, which is composed of
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 is widely
expressed in a variety of organs and cells including
epithelial, mesenchymal, hematopoietic, as well as
non-transformed cells. Axl signaling is important in many
cellular functions such as survival, anti-apoptosis,
proliferation, migration, and adhesion. Axl was
originally isolated from patients with chronic
myelogenous leukemia and a chronic myeloproliferative
disorder. Axl is overexpressed in many human cancers
including colon, squamous cell, thyroid, breast, and lung
carcinomas.

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.

is part of a larger superfamily that includes the
catalytic domains of 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. 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.

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.

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.

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
quiescence, and in inflammation.

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. DDR2 is a
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.

and an intracellular catalytic domain. The binding of
CSF-1R to its ligand, CSF-1, leads to receptor
dimerization, trans phosphorylation and activation, and
intracellular signaling. CSF-1R signaling is critical in
the regulation 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.

kinases, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates. Yes
(or c-Yes) 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. c-Yes
kinase is the cellular homolog of the oncogenic protein
(v-Yes) encoded by the Yamaguchi 73 and Esh sarcoma
viruses. It displays functional overlap with other Src
subfamily members, particularly Src. It also shows some
unique functions such as binding to occludins,
transmembrane proteins that regulate extracellular
interactions in tight junctions. Yes also associates with
a number of proteins in different cell types that Src
does not interact with, like JAK2 and gp130 in
pre-adipocytes, and Pyk2 in treated pulmonary vein
endothelial cells. Although the biological function of
Yes remains unclear, it appears to have a role in
regulating cell-cell interactions and vesicle trafficking
in polarized cells.

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.

is part of a larger superfamily that includes the
catalytic domains of 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. STRAD-beta is also referred to as ALS2CR2
(Amyotrophic lateral sclerosis 2 chromosomal region
candidate gene 2 protein), since the human gene encoding
it is located within the juvenile ALS2 critical region on
chromosome 2q33-q34. It is not linked to the development
of ALS2.

catalyze the transfer of the gamma-phosphoryl group from

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.

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.

Musk is a receptor tyr kinase (RTK) containing an

domains and a cysteine-rich cluster, a transmembrane
segment, and an intracellular catalytic domain. Musk is
expressed and concentrated in the postsynaptic membrane
in skeletal muscle. It is essential for the
establishment of the neuromuscular junction (NMJ), a
peripheral synapse that conveys signals from motor
neurons to muscle cells. Agrin, a large proteoglycan
released from motor neurons, stimulates Musk
autophosphorylation and activation, leading to the
clustering of acetylcholine receptors (AChRs). To date,
there is no evidence to suggest that agrin binds
directly to Musk. Mutations in AChR, Musk and other
partners are responsible for diseases of the NMJ, such
as the autoimmune syndrome myasthenia gravis.

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

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

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. Aatyk1 and Aatyk3 are
members of the Aatyk subfamily of proteins. Aatyk3 is a
receptor kinase containing a transmembrane segment and a
long C-terminal cytoplasmic tail with a catalytic domain.
Aatyk1 has a similar domain arrangement but without the
transmembrane segment and is thus, a cytoplasmic (or
nonreceptor) kinase. The expression of Aatyk1 (also
referred simply as Aatyk) is upregulated during growth
arrest and apoptosis in myeloid cells. Aatyk1 has been
implicated in neural differentiation, and is a regulator
of the Na-K-2Cl cotransporter, a membrane protein
involved in cell proliferation and survival, epithelial
transport, and blood pressure control. The function of
Aatyk3 is still unknown.

presence at the N terminus of signalling proteins and the
absence of the active-site residues in the catalytic and

domains of other kinases such as the typical
serine/threonine/tyrosine protein kinases (PKs),
aminoglycoside phosphotransferase, choline kinase, and

atypical protein serine kinases containing a kinase
catalytic signature, but otherwise show very little
sequence similarity to typical PKs. Serine kinases
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine residues in protein substrates. The RIO
catalytic domain is truncated compared to the catalytic
domains of typical PKs, with deletions of the loops
responsible for substrate binding. RIO2 is present in
archaea and eukaryotes. It contains an N-terminal winged
helix (wHTH) domain and a C-terminal RIO kinase
catalytic domain. The wHTH domain is primarily seen in
DNA-binding proteins, although some wHTH domains may be
involved in RNA recognition. RIO2 is essential for
survival and is necessary for rRNA cleavage during 40S
ribosomal subunit maturation. The biological substrates
of RIO2 are still unknown.

domain. RASAL1, GAP1(m), GAP1(IP4BP), and CAPRI are
all members of the GAP1 family of GTPase-activating
proteins. They contain N-terminal SH2-SH3-SH2 domains,
followed by two C2 domains, a PH domain, a RasGAP
domain, and a BTK domain. With the notable exception of
GAP1(m), they all possess an arginine finger-dependent
GAP activity on the Ras-related protein Rap1. They act
as a suppressor of RAS enhancing the weak intrinsic
GTPase activity of RAS proteins resulting in the
inactive GDP-bound form of RAS, allowing control of
cellular proliferation and differentiation. PH domains
share little sequence conservation, but all have a
common fold, which is electrostatically polarized. 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.

>gnl|CDD|240172 cd05151, ChoK, Choline Kinase (ChoK). The ChoK subfamily is part of
a larger superfamily that includes the catalytic domains
of other kinases, such as the typical
serine/threonine/tyrosine protein kinases (PKs), RIO
kinases, actin-fragmin kinase (AFK), and
phosphoinositide 3-kinase (PI3K). It is composed of
bacterial and eukaryotic choline kinases, as well as
eukaryotic ethanolamine kinase. ChoK catalyzes the
transfer of the gamma-phosphoryl group from ATP (or CTP)
to its substrate, choline, producing phosphorylcholine
(PCho), a precursor to the biosynthesis of two major
membrane phospholipids, phosphatidylcholine (PC), and
sphingomyelin (SM). Although choline is the preferred
substrate, ChoK also shows substantial activity towards
ethanolamine and its N-methylated derivatives. Bacterial
ChoK is also referred to as licA protein. ETNK catalyzes
the transfer of the gamma-phosphoryl group from CTP to
ethanolamine (Etn), the first step in the CDP-Etn
pathway for the formation of the major phospholipid,
phosphatidylethanolamine (PtdEtn). Unlike ChoK, ETNK
shows specific activity for its substrate and displays
negligible activity towards N-methylated derivatives of
Etn. ChoK plays an important role in cell signaling
pathways and the regulation of cell growth.

domain, repeat 2. The functions of these fungal
proteins are unknown, but they all contain 2 PH domains.
This cd represents the second PH repeat. 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.

Tyrosine Kinase (PTK) family; Apoptosis-associated
tyrosine kinase 2 (Aatyk2); 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. Aatyk2 is
a member of the Aatyk subfamily of proteins, which are
receptor kinases containing a transmembrane segment and
a long C-terminal cytoplasmic tail with a catalytic
domain. Aatyk2 is also called lemur tyrosine kinase 2
(Lmtk2) or brain-enriched kinase (Brek). It is expressed
at high levels in early postnatal brain, and has been
shown to play a role in nerve growth factor (NGF)
signaling. Studies with knockout mice reveal that Aatyk2
is essential for late stage spermatogenesis. Although it
is classified as a tyr kinase based on sequence
similarity and the phylogenetic tree, Aatyk2 has been
characterized as a serine/threonine kinase.

finger is a C4HC3 zinc-finger-like motif found in
nuclear proteins thought to be involved in epigenetics
and chromatin-mediated transcriptional regulation. The
PHD finger binds two zinc ions using the so-called
'cross-brace' motif and is thus structurally related to
the RING finger and the FYVE finger. It is not yet known
if PHD fingers have a common molecular function. Several
reports suggest that it can function as a
protein-protein interacton domain and it was recently
demonstrated that the PHD finger of p300 can cooperate
with the adjacent BROMO domain in nucleosome binding in
vitro. Other reports suggesting that the PHD finger is a
ubiquitin ligase have been refuted as these domains were
RING fingers misidentified as PHD fingers.
