>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.

>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.

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

dual-specificity MAP kinase kinases and similar
proteins. 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.

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

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

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

CDK9, BUR1, and CdkC are functionally equivalent. They
act as a kinase for the C-terminal domain of RNA
polymerase II and participate in regulating mutliple
steps of gene expression including transcription
elongation and RNA processing. CDK9 and CdkC associate
with T-type cyclins while BUR1 associates with the

found in splicing factors. CDK12 interacts with cyclins
L1 and L2, and participates in regulating transcription
and alternative splicing.

STKs catalyze the transfer of the gamma-phosphoryl group

superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,

mediators of cellular 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.

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.

are plant phototropins and predominantly uncharacterized
fungal STKs whose catalytic domains resemble the
phototropin kinase domain. One protein from Neurospora
crassa is called nrc-2. Phototropins are blue-light
receptors that 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
Voltage) domains that binds FMN. Photoexcitation of the
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.

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

partner with D-type cyclins to regulate the early G1
phase of the cell cycle. They are the first kinase
activated by mitogenic signals to release cells from the
G0 arrested state. CDK4 and CDK6 are both expressed
ubiquitously, associate with all three D cyclins (D1, D2

protein. They are also regulated by the INK4 family of
inhibitors which associate with either the CDK alone or
the CDK/cyclin complex. CDK4 and CDK6 show differences
in subcellular localization, sensitivity to some
inhibitors, timing in activation, tumor selectivity, and
possibly substrate profiles. Although CDK4 and CDK6 seem
to show some redundancy, they also have discrete,
nonoverlapping functions. CDK6 plays an important role
in cell differentiation.

STKs catalyze the transfer of the gamma-phosphoryl group

substrates. The cGK subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,

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.

to extracellular signals. The pathways involve a triple
kinase core cascade comprising the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK or MAP2K), which itself is phosphorylated
and activated by a MAPK kinase kinase (MAPKKK or MKKK or
MAP3K). MAPKKs are dual-specificity PKs that
phosphorylate their downstream targets, MAPKs, at
specific threonine and tyrosine residues. There are
three MAPK subfamilies: extracellular signal-regulated
kinase (ERK), c-Jun N-terminal kinase (JNK), and p38. In
mammalian cells, there are seven MAPKKs (named MKK1-7)
and 20 MAPKKKs. Each MAPK subfamily can be activated by
at least two cognate MAPKKs and by multiple MAPKKKs.

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.

Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK7
plays essential roles in the cell cycle and in
transcription. It associates with cyclin H and MAT1 and
acts as a CDK-Activating Kinase (CAK) by phosphorylating
and activating cell cycle CDKs (CDK1/2/4/6). In the
brain, it activates CDK5. CDK7 is also a component of
the general transcription factor TFIIH, which
phosphorylates the 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 initiation.

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.

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

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.

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).

Serine/Threonine Kinases (STKs), Male germ
cell-Associated Kinase (MAK)-like subfamily, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAK-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. This subfamily is composed of human MAK and
MAK-related kinase (MRK), Saccharomyces cerevisiae
Ime2p, Schizosaccharomyces pombe Mei4-dependent protein
3 (Mde3) and Pit1, Caenorhabditis elegans dyf-5,
Arabidopsis thaliana MHK, and similar proteins. These
proteins play 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.

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.

contains only one catalytic kinase domain, unlike p90
ribosomal S6 kinases (RSKs). It acts as a downstream
effector of the STK mTOR (mammalian Target of Rapamycin)
and plays a role in the regulation of the translation
machinery during protein synthesis. p70S6K also plays a
pivotal role in regulating cell size and glucose
homeostasis. Its targets include S6, the translation

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, 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.

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

Kinase, Cyclin-Dependent protein Kinase 10.
Serine/Threonine Kinases (STKs), Cyclin-dependent
protein Kinase 10 (CDK10) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK10 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. CDK10, also called PISSLRE, is essential for
cell growth and proliferation, and acts through the G2/M
phase of the cell cycle. CDK10 has also been identified
as an important factor in endocrine therapy resistance
in breast cancer. CDK10 silencing increases the
transcription of c-RAF and the activation of the p42/p44
MAPK pathway, which leads to antiestrogen resistance.
Patients who express low levels of CDK10 relapse early
on tamoxifen.

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.

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

CDC2L1 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. 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).

Serine/Threonine Kinases. Serine/Threonine Kinases
(STKs), PCTAIRE-like subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The PCTAIRE-like subfamily is part of a
larger superfamily that includes the catalytic domains
of other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. Members of this
subfamily share sequence similarity with
Cyclin-Dependent Kinases (CDKs), which belong to a large
family of STKs that are regulated by their cognate
cyclins. Together, CDKs and cyclins are involved in the
control of cell-cycle progression, transcription, and
neuronal function. The association of PCTAIRE-like
proteins with cyclins has not been widely studied,
although PFTAIRE-1 has been shown to function as a CDK
which is regulated by cyclin D3 as well as the
membrane-associated cyclin Y. PCTAIRE-like proteins show
unusual expression patterns with high levels in
post-mitotic tissues, suggesting that they may be
involved in regulating post-mitotic cellular events.

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.

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.

contains an N-terminal pleckstrin homology (PH) domain
and a C-terminal catalytic domain. PKB-alpha is
predominantly expressed in endothelial cells. It is
critical for the regulation of angiogenesis and the
maintenance of vascular integrity. It also plays a role
in adipocyte differentiation. Mice deficient in
PKB-alpha exhibit perinatal morbidity, growth
retardation, reduction in body weight accompanied by
reduced sizes of multiple organs, and enhanced apoptosis
in some cell types. PKB-alpha activity has been reported
to be frequently elevated in breast and prostate
cancers. In some cancer cells, PKB-alpha may act as a
suppressor of metastasis.

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.

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

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

contain an N-terminal catalytic domain and a C-terminal
citron homology (CNH) regulatory domain, similar to
MAP4K4/6. MAP4Ks are involved in some MAPK signaling
pathways that are important in mediating cellular
responses to extracellular signals by activating a MAPK
kinase kinase (MAPKKK or MAP3K or MKKK). Each MAPK
cascade is activated either by a small GTP-binding
protein or by an adaptor protein, which transmits the
signal either directly to a MAP3K to start the triple
kinase core cascade or indirectly through a mediator
kinase, a MAP4K. MAP4K1, also called haematopoietic
progenitor kinase 1 (HPK1), is a hematopoietic-specific
STK involved in many cellular signaling cascades
including MAPK, antigen receptor, apoptosis, growth
factor, and cytokine signaling. It participates in the
regulation of T cell receptor signaling and T
cell-mediated immune responses. MAP4K2 was referred to
as germinal center (GC) kinase because of its preferred
location in GC B cells. MAP4K3 plays a role in the
nutrient-responsive pathway of mTOR (mammalian target of
rapamycin) signaling. It is required in the activation
of S6 kinase by amino acids and for the phosphorylation
of the mTOR-regulated inhibitor of eukaryotic initiation
factor 4E. MAP4K5, also called germinal center
kinase-related enzyme (GCKR), has been shown to activate
the MAPK c-Jun N-terminal kinase (JNK).

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

Studies in knockout mice result in different phenotypes,
suggesting that the two isoforms do not compensate for
each other during embryonic development.

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

Tyrosine Kinases. Protein Tyrosine Kinase (PTK) family;
Src kinase subfamily; catalytic (c) domain. Src
subfamily members include Src, Lck, Hck, Blk, Lyn, Fgr,
Fyn, Yrk, and Yes. 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.
Src (or c-Src) proteins are cytoplasmic (or
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.

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

cytoplasmic (or nonreceptor) tyr kinase that contains an
autophosphorylation site and a FERM domain at the
N-terminus, a central tyr kinase domain, proline-rich
regions, and a C-terminal FAT (focal adhesion targeting)
domain. FAK activity is dependent on integrin-mediated
cell adhesion, which facilitates N-terminal
autophosphorylation. Full activation is achieved by the
phosphorylation of its two adjacent A-loop tyrosines.
FAK is important in mediating signaling initiated at
sites of cell adhesions and at growth factor receptors.
Through diverse molecular interactions, FAK functions as
a biosensor or integrator to control cell motility. It
is a key regulator of cell survival, proliferation,
migration and invasion, and thus plays an important role
in the development and progression of cancer. Src binds
to autophosphorylated FAK forming the FAK-Src dual
kinase complex, which is activated in a wide variety of
tumor cells and generates signals promoting growth and
metastasis. FAK is being developed as a target for
cancer therapy.

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

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.

Tyrosine Kinases, Janus kinases. Protein Tyrosine
Kinase (PTK) family; Janus kinase (Jak) subfamily;
catalytic (c) domain (repeat 2). The Jak subfamily is
composed of Jak1, Jak2, Jak3, TYK2, 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.
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.

superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,

of STKs that are regulated by their cognate cyclins.
Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK6
is regulated by D-type cyclins and INK4 inhibitors. It
is active towards the retinoblastoma (pRb) protein,
implicating it to function in regulating the early G1
phase of the cell cycle. It is expressed ubiquitously
and is localized in the cytoplasm. It is also present in
the ruffling edge of spreading fibroblasts and may play
a role in cell spreading. It binds to the p21 inhibitor
without any effect on its own activity and it is
overexpressed in squamous cell carcinomas and
neuroblastomas. CDK6 has also been shown to inhibit cell
differentiation in many cell types.

T-cells and NK cells, and is a crucial component in
T-cell receptor (TCR) signaling. Zap-70 binds the
phosphorylated ITAM (immunoreceptor tyr activation
motif) sequences of the activated TCR zeta-chain through
its SH2 domains, leading to its phosphorylation and
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.

critical to oncogenic signaling mediated by Ras and
Bcr-Abl. The PKC-iota gene is the target of
tumor-specific gene amplification in many human cancers,
and has been identified as a human oncogene. In addition
to its role in transformed growth, PKC-iota also
promotes invasion, chemoresistance, and tumor cell
survival. Expression profiling of PKC-iota is a

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.

composed of the MAPKs MPK1 from Saccharomyces
cerevisiae, Pmk1 from Schizosaccharomyces pombe, and
similar proteins. MAPKs are important mediators of
cellular responses to extracellular signals. MPK1 (also

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

>gnl|CDD|132965 cd06634, STKc_TAO2, Catalytic domain of the Protein
Serine/Threonine Kinase, Thousand-and-one amino acids 2.
Serine/threonine kinases (STKs), thousand-and-one amino
acids 2 (TAO2) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The TAO 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.
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).

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.

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

Serine/Threonine Kinase, Thousand-and-one amino acids 3.
Serine/threonine kinases (STKs), thousand-and-one amino
acids 3 (TAO3) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The TAO 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.
TAO3 is also known as JIK (JNK inhibitory kinase) or KFC
(kinase from chicken). It specifically activates c-Jun
N-terminal kinase (JNK), presumably by phosphorylating
and activating MKK4/MKK7. In Saccharomyces cerevisiae,
TAO3 is a component of the RAM (regulation of Ace2p
activity and cellular morphogenesis) signaling pathway.
TAO3 is upregulated in retinal ganglion cells after
axotomy, and may play a role in apoptosis.

Serine/Threonine Kinases (STKs), Novel Protein Kinase C
(nPKC), eta 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-eta
is predominantly expressed in squamous epithelia, where
it plays a crucial role in the signaling of cell-type
specific differentiation. It is also expressed in pro-B
cells and early-stage thymocytes, and acts as a key
regulator in early B-cell development. PKC-eta increases
glioblastoma multiforme (GBM) proliferation and
resistance to radiation, and is being developed as a
therapeutic target for the management of GBM.

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.

GRK1 to GRK7. GRK7, also called iodopsin kinase, belongs
to the visual group of GRKs. It is primarily found in
the retina and plays a role in the regulation of opsin
light receptors. GRK7 is located in retinal cone outer
segments and plays an important role in regulating
photoresponse of the cones.

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.

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.

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, Class EphA Ephrin Receptors. Protein Tyrosine
Kinase (PTK) family; Ephrin Receptor (EphR) subfamily;
most class EphA receptors including EphA3, EphA4, EphA5,
and EphA7, but excluding EphA1, EphA2 and EphA10;
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. EphRs comprise the
largest subfamily of receptor tyr kinases (RTKs). In
general, class EphA receptors bind GPI-anchored ephrin-A
ligands. There are ten vertebrate EphA receptors
(EphA1-10), which display promiscuous interactions with
six ephrin-A ligands. One exception is EphA4, which also
binds ephrins-B2/B3. EphRs contain an ephrin-binding
domain and two fibronectin repeats extracellularly, a
transmembrane segment, and a cytoplasmic tyr kinase
domain. Binding of the ephrin ligand to EphR requires
cell-cell contact since both are anchored to the plasma
membrane. The resulting downstream signals occur
bidirectionally in both EphR-expressing cells (forward
signaling) and ephrin-expressing cells (reverse
signaling). Ephrin/EphR interaction mainly results in
cell-cell repulsion or adhesion, making it important in
neural development and plasticity, cell morphogenesis,
cell-fate determination, embryonic development, tissue
patterning, and angiogenesis. EphARs and ephrin-A
ligands are expressed in multiple areas of the
developing brain, especially in the retina and tectum.
They are part of a system controlling retinotectal
mapping.

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,

Protein Tyrosine Kinases. Protein Tyrosine Kinase (PTK)
family; Human Fyn-related kinase (Frk) and similar
proteins; catalytic (c) domain. The PTKc family is part
of a larger superfamily that includes the catalytic
domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Frk and
Srk are members of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases contain an N-terminal SH4 domain with a
myristoylation site, followed by SH3 and SH2 domains, a
tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr. They are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the
C-terminal tyr by Csk (C-terminal Src Kinase). Src
proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Frk, also known as Rak, is specifically
expressed in liver, lung, kidney, intestine, mammary
glands, and the islets of Langerhans. Rodent homologs
were previously referred to as GTK (gastrointestinal tyr
kinase), BSK (beta-cell Src-like kinase), or IYK
(intestinal tyr kinase). Studies in mice reveal that Frk
is not essential for viability. It plays a role in the
signaling that leads to cytokine-induced beta-cell death
in Type I diabetes. It also regulates beta-cell number
during embryogenesis and early in life.

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

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.

PKs catalyze the transfer of the gamma-phosphoryl group

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

Abelson (Abl) kinase; 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. 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.

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.

(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. Members of the
GRK4-like group include GRK4, GRK5, GRK6, and similar
GRKs. GRKs in this group contain an N-terminal RGS

G protein betagamma-subunit binding domain. They are
localized to the plasma membrane through
post-translational lipid modification or direct binding
to PIP2.

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.

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.

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.

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). MKK4 is a dual-specificity PK that
phosphorylates and activates the downstream targets,
c-Jun N-terminal kinase (JNK) and p38 MAPK, on specific
threonine and tyrosine residues. JNK and p38 are
collectively known as stress-activated MAPKs, as they
are activated in response to a variety of environmental
stresses and pro-inflammatory cytokines. Their
activation is associated with the induction of cell
death. Mice deficient in MKK4 die during embryogenesis
and display anemia, severe liver hemorrhage, and
abnormal hepatogenesis. MKK4 may also play roles in the
immune system and in cardiac hypertrophy. It plays a
major role in cancer as a tumor and metastasis
suppressor. Under certain conditions, MKK4 is
pro-oncogenic.

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

(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.

comprise the largest subfamily of receptor tyr kinases

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

protein-coupled receptors (GPCRs), the largest
superfamily of cell surface receptors which regulate
some part of nearly all physiological functions.
Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. GRK5 is widely expressed in many tissues.
It associates with the membrane though an N-terminal
PIP2 binding domain and also binds phospholipids via its
C-terminus. GRK5 deficiency is associated with early
Alzheimer's disease in humans and mouse models. GRK5
also plays a crucial role in the pathogenesis of
sporadic Parkinson's disease. It participates in the
regulation and desensitization of PDGFRbeta, a receptor
tyrosine kinase involved in a variety of downstream
cellular effects including cell growth, chemotaxis,
apoptosis, and angiogenesis. GRK5 also regulates
Toll-like receptor 4, which is involved in innate and
adaptive immunity.

Serine/threonine 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.

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

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.

Serine/Threonine Kinase, beta-adrenergic receptor
kinase. 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.

functions downstream of the MAPK kinase kinase Tak1,
which also plays a role in activating the JNK and p38
MAPKs. The Tak1/NLK pathways are regulated by Wnts, a
family of secreted proteins that is critical in the
control of asymmetric division and cell polarity. NLK
can phosphorylate transcription factors from the TCF/LEF

NLK is involved in regulating androgen receptor-mediated
transcription and its expression is altered during
cancer progression.

(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). PAK2 plays a

activated by caspases leading to morphological changes
during apoptosis. PAK2 is also activated in response to
a variety of stresses including DNA damage,
hyperosmolarity, serum starvation, and contact
inhibition, and may play a role in coordinating the
stress response. PAK2 also contributes to cancer cell

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)

proliferation, IL-2 production and phopholipase C-gamma1
activation.

Serine/Threonine Kinase, p21-activated kinase 1.
Serine/threonine kinases (STKs), p21-activated kinase
(PAK) 1, 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 from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
PAK1 belongs to group I. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). 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.

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)

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. 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.

receptor tyr kinases (RTKs) whose ligands are not yet
well-defined. RTKs contain an extracellular
ligand-binding domain, a transmembrane region, and an
intracellular tyr kinase domain. They are usually
activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain. ALK appears
to play an 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 large cell lymphomas (ALCLs). ALK
fusion proteins are 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 erythematosus.

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.

PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on

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

Musk is a receptor tyr kinase (RTK) containing an
extracellular region with four immunoglobulin-like
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.

have been detected in many transformed cell lines and
several human tumors. In addition, PKC-alpha is required
for HER2 dependent breast cancer invasion.

Kinase, Ephrin Receptor A2. Protein Tyrosine Kinase
(PTK) family; Ephrin Receptor (EphR) subfamily; EphA2
receptor; 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. 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.

(nPKC), delta isoform, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from

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-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.

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

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.

STKs catalyze the transfer of the gamma-phosphoryl group

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

(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.

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

important in cell proliferation and development. Mice,
with a deletion of DDR2, suffer from dwarfism and

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

receptor tyr kinase (RTK) containing an extracellular
region with four cadherin-like repeats, a
calcium-binding site, and a cysteine-rich domain, a
transmembrane segment, and an intracellular catalytic
domain. It is part of a multisubunit complex that binds
glial-derived neurotropic factor (GDNF) family ligands
(GFLs) including GDNF, neurturin, artemin, and
persephin. GFLs bind RET along with four GPI-anchored
coreceptors, bringing two RET molecules together,
leading to autophosphorylation, activation, and
intracellular signaling. RET is essential for the
development of the sympathetic, parasympathetic and
enteric nervous systems, and the kidney. RET disruption
by germline mutations causes diseases in humans
including congenital aganglionosis of the
gastrointestinal tract (Hirschsprung's disease) and
three related inherited cancers: multiple endocrine
neoplasia type 2A (MEN2A), MEN2B, and familial medullary
thyroid carcinoma (FMTC).

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

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

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

(HER1, ErbB1) 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. 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

kinases (STKs), mitogen-activated protein kinase (MAPK)
kinase kinase kinase 4 (MAPKKKK4 or MAP4K4) and MAPKKKK6
(or MAP4K6) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The MAP4K4/MAP4K6 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. MAP4Ks (or
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.

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. HER4 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. 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.

Protein Tyrosine Kinases, Janus kinases 2 and 3.
Protein Tyrosine Kinase (PTK) family; Janus kinase 2
(Jak2) and Jak3; catalytic (c) domain (repeat 2). The
PTKc family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. 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).

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.

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),

with Inca (induced in neural crest by AP2) in the
regulation of cell adhesion and cytoskeletal
organization in the embryo and in neural crest cells
during craniofacial development. PAK5 may also play a

Yrk are members of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases contain an N-terminal SH4 domain with a
myristoylation site, followed by SH3 and SH2 domains, a
tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr. They are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the
C-terminal tyr by Csk (C-terminal Src Kinase). Src
proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Fyn, together with Lck, plays a
critical role in T-cell signal transduction by
phosphorylating ITAM (immunoreceptor tyr activation
motif) sequences on T-cell receptors, ultimately leading
to the proliferation and differentiation of T-cells. In
addition, Fyn is involved in the myelination of neurons,
and is implicated in Alzheimer's and Parkinson's
diseases. Yrk has been detected only in chickens. It is
primarily found in neuronal and epithelial cells and in
macrophages. It may play a role in inflammation and in
response to injury.

Inactivation of LATS1 in mice results in the development
of various tumors, including sarcomas and ovarian
cancer. Promoter methylation, loss of heterozygosity,
and missense mutations targeting the LATS1 gene have
also been found in human sarcomas and ovarian cancers.
In addition, decreased expression of LATS1 is associated
with an aggressive phenotype and poor prognosis. LATS1
induces G2 arrest and promotes cytokinesis. It may be a
component of the mitotic exit network in higher
eukaryotes.

NT3/TrkC signaling plays an important role in the
innervation of the cardiac conducting system and the

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

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

Kinase, HER2. Protein Tyrosine Kinase (PTK) family;
HER2 (ErbB2, HER2/neu); catalytic (c) domain. The PTKc
family is part of a larger superfamily that includes the
catalytic domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. HER2 is a
member of the EGFR (HER, ErbB) subfamily of proteins,
which are receptor tyr kinases (RTKs) containing an
extracellular EGF-related ligand-binding region, a
transmembrane helix, and a cytoplasmic region with a tyr
kinase domain and a regulatory C-terminal tail. Unlike
other tyr kinases, phosphorylation of the activation
loop of EGFR proteins is not critical to their
activation. Instead, they are activated by
ligand-induced dimerization, leading to the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. HER2 does not bind to any known EGFR
subfamily ligands, but contributes to the kinase
activity of all possible heterodimers. It acts as the
preferred partner with other ligand-bound EGFR proteins
and functions as a signal amplifier, with the HER2-HER3
heterodimer being the most potent pair in mitogenic
signaling. HER2 plays an important role in cell
development, proliferation, survival and motility.
Overexpression of HER2 results in its activation and
downstream signaling, even in the absence of ligand.
HER2 overexpression, mainly due to gene amplification,
has been shown in a variety of human cancers. Its role
in breast cancer is especially well-documented. HER2 is
up-regulated in about 25% of breast tumors and is
associated with increases in tumor aggressiveness,
recurrence and mortality. HER2 is a target for
monoclonal antibodies and small molecule inhibitors,
which are being developed as treatments for cancer. The
first humanized antibody approved for clinical use is
Trastuzumab (Herceptin), which is being used in
combination with other therapies to improve the survival
rates of patients with HER2-overexpressing breast
cancer.

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

Ron are receptor tyr kinases (RTKs) composed of an
alpha-beta heterodimer. The extracellular alpha chain is
disulfide linked to the beta chain, which contains an
extracellular ligand-binding region with a sema domain,
a PSI domain and four IPT repeats, a transmembrane
segment, and an intracellular catalytic domain. Binding
to their ligands leads to receptor dimerization,
autophosphorylation, activation, and intracellular

factor/scatter factor (HGF/SF), and is also called the
HGF receptor. HGF/Met signaling plays a role in growth,
transformation, cell motility, invasion, metastasis,
angiogenesis, wound healing, and tissue regeneration.
Aberrant expression of Met through mutations or gene
amplification is associated with many human cancers
including hereditary papillary renal and gastric
carcinomas. The ligand for Ron is macrophage stimulating

kinases contain an N-terminal SH4 domain with a
myristoylation site, followed by SH3 and SH2 domains, a
tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr. They are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the
C-terminal tyr by Csk (C-terminal Src Kinase). Src
proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Hck is present in myeloid and lymphoid
cells that play a role in the development of cancer. It
may be important in the oncogenic signaling of the
protein Tel-Abl, which induces a chronic myelogenous
leukemia (CML)-like disease. Hck also acts as a negative
regulator of granulocyte colony-stimulating factor
(G-CSF)-induced proliferation of granulocytic
precursors, suggesting a possible role in the
development of acute myeloid leukemia (AML). In
addition, Hck is essential in regulating the
degranulation of polymorphonuclear leukocytes (PMNs).
Genetic polymorphisms affect the expression level of
Hck, which affects PMN mediator release and influences
the development of chronic obstructive pulmonary disease
(COPD).

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

of inflammation and angiogenesis.

Yes. Protein Tyrosine Kinase (PTK) family; Yes kinase;
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. 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.

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.

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

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.

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.

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). 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.

subfamily, catalytic (c) domain. STKs catalyze the

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

that includes the catalytic domains of other kinases
such as protein serine/threonine kinases, RIO kinases,

proteins are orphan receptor tyr kinases (RTKs)
containing an extracellular region with
immunoglobulin-like, cysteine-rich, and kringle domains,
a transmembrane segment, and an intracellular catalytic
domain. Ror RTKs are unrelated to the nuclear receptor
subfamily called retinoid-related orphan receptors
(RORs). RTKs are usually activated through ligand
binding, which causes dimerization and
autophosphorylation of the intracellular tyr kinase
catalytic domain. Ror kinases are expressed in many
tissues during development. 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 skeletal abnormalities found in Ror2-deficient
mice.

The Aatyk subfamily is also referred to as the lemur

(Lmtk1), Aatyk2 (Lmtk2, Brek), Aatyk3 (Lmtk3), and
similar proteins. The PTKc family is part of a larger

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

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.

signaling. PDGFR subfamily receptors are important in
the development of a variety of cells. PDGFRs are

Protein Tyrosine Kinase (PTK) family; Receptor tyrosine
kinase-like Orphan Receptor 2 (Ror2); 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. Ror
proteins are orphan receptor tyr kinases (RTKs)
containing an extracellular region with
immunoglobulin-like, cysteine-rich, and kringle domains,
a transmembrane segment, and an intracellular catalytic
domain. Ror RTKs are unrelated to the nuclear receptor
subfamily called retinoid-related orphan receptors
(RORs). RTKs are usually activated through ligand
binding, which causes dimerization and
autophosphorylation of the intracellular tyr kinase
catalytic domain. Ror2 plays important roles in skeletal
and heart formation. Ror2-deficient mice show widespread
bone abnormalities, ventricular defects in the heart,
and respiratory dysfunction. Mutations in human Ror2
result in two different bone development genetic
disorders, recessive Robinow syndrome and brachydactyly
type B. Ror2 is also implicated in neural development.

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

part of a larger superfamily that includes the catalytic

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. MAP4K3 plays a role in the
nutrient-responsive pathway of mTOR (mammalian target of
rapamycin) signaling. MAP4K3 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. mTOR regulates ribosome
biogenesis and protein translation, and is frequently
deregulated in cancer.

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

In the cochlear duct and in the lens, FGFR3 is involved
in differentiation while it appears to have a role in
cell proliferation in epithelial cells. Germline
mutations in FGFR3 are associated with skeletal
disorders including several forms of dwarfism. Some

Kinases, Vascular Endothelial Growth Factor Receptors.
Protein Tyrosine Kinase (PTK) family; Vascular
Endothelial Growth Factor Receptor (VEGFR) subfamily;
catalytic (c) domain. The VEGFR subfamily consists of
VEGFR1 (Flt1), VEGFR2 (Flk1), VEGFR3 (Flt4), 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.
VEGFR subfamily members are receptor tyr kinases (RTKs)
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 three VEGFRs, which can form homo or
heterodimers. VEGFRs 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 cell migration, survival, and
proliferation. VEGFR1 binds VEGFA, VEGFB, and placenta
growth factor (PLGF). It regulates monocyte and
macrophage migration, vascular permeability,
haematopoiesis, and the recruitment of haematopietic
progenitor cells from the bone marrow.

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 in cancer progression and
lymph node metastasis. Missense mutations in the VEGFR3
gene are associated with primary human lymphedema.

and nitric oxide synthesis. Insulin resistance, caused
by abnormalities in InsR signaling, has been described
in diabetes, hypertension, cardiovascular disease,

ribosomal protein S6 kinase-like 1), which also contains
MIT and kinase domains but lacks a PX domain. RPK118
binds sphingosine kinase, a key enzyme in the synthesis
of sphingosine 1-phosphate (SPP), a lipid messenger
involved in many cellular events. RPK118 may be involved
in transmitting SPP-mediated signaling. RPK118 also
binds the antioxidant peroxiredoxin-3 (PRDX3). RPK118
may be involved in the transport of PRDX3 from the
cytoplasm to its site of function in the mitochondria.

Kinase, Vascular Endothelial Growth Factor Receptor 2.
Protein Tyrosine Kinase (PTK) family; Vascular
Endothelial Growth Factor Receptor 2 (VEGFR2); 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.
VEGFR2 (or Flk1) is a member of the VEGFR subfamily of
proteins, which are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
seven immunoglobulin (Ig)-like domains, a transmembrane
segment, and an intracellular catalytic domain. The
binding of VEGFRs to their ligands, the VEGFs, leads to
receptor dimerization, activation, and intracellular
signaling. The carboxyl terminus of VEGFR2 plays an
important role in its autophosphorylation and
activation. VEGFR2 binds the ligands VEGFA, VEGFC, VEGFD
and VEGFE. VEGFR2 signaling is implicated in all aspects
of normal and pathological vascular endothelial cell
biology. It induces a variety of cellular effects
including migration, survival, and proliferation. It is
critical in regulating embryonic vascular development
and angiogenesis. VEGFR2 is the major signal transducer
in pathological angiogenesis including cancer and
diabetic retinopathy, and is a target for inhibition in
cancer therapy.

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.

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).

of a larger superfamily, that includes the catalytic
domains of other kinases such as the typical
serine/threonine/tyrosine protein kinases (PKs),
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase (PI3K). RIO kinases are
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.

to the N-terminal domain of Wnt inhibitory factor-1
(WIF) and serves as the ligand (Wnt) binding domain of
Ryk. Ryk is expressed in many different tissues both
during development and in adults, suggesting a
widespread function. It acts as a chemorepulsive axon
guidance receptor of Wnt glycoproteins and is
responsible for the establishment of axon tracts during
the development of the central nervous system. In
addition, studies in mice reveal that Ryk is essential
in skeletal, craniofacial, and cardiac development.
Thus, it appears Ryk is involved in signal transduction
despite its lack of kinase activity. Ryk may function as
an accessory protein that modulates the signals coming
from catalytically active partner RTKs such as the Eph
receptors.

>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.

protein product of the dentatorubral-pallidoluysian
atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive
neurodegenerative disorder. It is caused by the
expansion of a CAG repeat in the DRPLA gene on
chromosome 12p. This results in an extended
polyglutamine region in atrophin-1, that is thought to
confer toxicity to the protein, possibly through
altering its interactions with other proteins. The
expansion of a CAG repeat is also the underlying defect
in six other neurodegenerative disorders, including
Huntington's disease. One interaction of expanded
polyglutamine repeats that is thought to be pathogenic
is that with the short glutamine repeat in the
transcriptional coactivator CREB binding protein, CBP.
This interaction draws CBP away from its usual nuclear
location to the expanded polyglutamine repeat protein
aggregates that are characteristic of the polyglutamine
neurodegenerative disorders. This interferes with
CBP-mediated transcription and causes cytotoxicity.

coiled-coil region, in p54nrb/PSF/PSP1 homologs from
invertebrate species. The family contains a DBHS domain
(for Drosophila behavior, human splicing), which
comprises two conserved RNA recognition motifs (RRMs),
also termed RBDs (RNA binding domains) or RNPs
(ribonucleoprotein domains), and a charged
protein-protein interaction NOPS (NONA and PSP1) domain.
This model corresponds to the NOPS domain, with a long
helical C-terminal extension , found in Drosophila
melanogaster gene no-ontransient A (nonA) encoding
puff-specific protein Bj6 (also termed NONA), Chironomus
tentans hrp65 gene encoding protein Hrp65 and similar
proteins. D. melanogaster NONA is involved in eye
development and behavior, and may play a role in
circadian rhythm maintenance, similar to vertebrate
p54nrb. C. tentans hrp65 is a component of nuclear
fibers associated with ribonucleoprotein particles in
transit from the gene to the nuclear pore. The NOPS
domain specifically binds to the second RNA recognition
motif (RRM2) domain of the partner DBHS protein via a
substantial interaction surface. Its highly conserved
C-terminal residues are critical for functional DBHS
dimerization while the highly conserved C-terminal
helical extension, forming a right-handed antiparallel
heterodimeric coiled-coil, is essential for localization
of these proteins to subnuclear bodies.

autophagy-related subunit 14. The Atg14 or Apg14
proteins are hydrophilic proteins with a predicted
molecular mass of 40.5 kDa, and have a coiled-coil motif
at the N terminus region. Yeast cells with mutant Atg14
are defective not only in autophagy but also in sorting
of carboxypeptidase Y (CPY), a vacuolar-soluble
hydrolase, to the vacuole. Subcellular fractionation
indicate that Apg14p and Apg6p are peripherally
associated with a membrane structure(s). Apg14p was
co-immunoprecipitated with Apg6p, suggesting that they
form a stable protein complex. These results imply that
Apg6/Vps30p has two distinct functions: in the
autophagic process and in the vacuolar protein sorting
pathway. Apg14p may be a component specifically required
for the function of Apg6/Vps30p through the autophagic
pathway. There are 17 auto-phagosomal component proteins
which are categorized into six functional units, one of
which is the AS-PI3K complex (Vps30/Atg6 and Atg14). The
AS-PI3K complex and the Atg2-Atg18 complex are essential
for nucleation, and the specific function of the AS-PI3K
apparently is to produce phosphatidylinositol
3-phosphate (PtdIns(3)P) at the pre-autophagosomal
structure (PAS). The localisation of this complex at the
PAS is controlled by Atg14. Autophagy mediates the
cellular response to nutrient deprivation, protein
aggregation, and pathogen invasion in humans, and
malfunction of autophagy has been implicated in multiple
human diseases including cancer. This effect seems to be
mediated through direct interaction of the human Atg14
with Beclin 1 in the human phosphatidylinositol 3-kinase
class III complex.

kinase adapter protein alpha. Protein Kinase family,
STE20-related kinase adapter protein (STRAD) alpha
subfamily, pseudokinase domain. The STRAD alpha
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. 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.
