>gnl|CDD|173670 cd05579, STKc_MAST_like, Catalytic domain of Microtubule-associated
serine/threonine kinase-like proteins. Serine/Threonine
Kinases (STKs), Microtubule-associated serine/threonine
(MAST) kinase subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The MAST kinase subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. The MAST kinase subfamily
includes MAST kinases, MAST-like (MASTL) kinases, and
fungal kinases with similarity to Saccharomyces
cerevisiae Rim15 and Schizosaccharomyces pombe cek1.
MAST kinases contain an N-terminal domain of unknown
function, a central catalytic domain, and a C-terminal
PDZ domain that mediates protein-protein interactions.
MASTL kinases carry only a catalytic domain which
contains a long insert relative to other kinases. The
fungal kinases in this subfamily harbor other domains in
addition to a central catalytic domain, which also
contains an insert relative to MAST kinases like MASTL.
Rim15 contains a C-terminal signal receiver (REC) domain
while cek1 contains an N-terminal PAS domain. MAST
kinases are cytoskeletal associated kinases of unknown
function that are also expressed at neuromuscular
junctions and postsynaptic densities. The fungal
proteins Rim15 and cek1 are involved in the regulation
of meiosis and mitosis, respectively.

>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.

Serine/Threonine Kinase, Phosphoinositide-dependent
kinase 1. Serine/Threonine Kinases (STKs),
Phosphoinositide-dependent kinase 1 (PDK1) subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The PDK1 subfamily is
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). PDK1
carries an N-terminal catalytic domain and a C-terminal
pleckstrin homology (PH) domain that binds
phosphoinositides. It phosphorylates the activation loop
of AGC kinases that are regulated by PI3K such as PKB,
SGK, and PKC, among others, and is crucial for their
activation. Thus, it contributes in regulating many
processes including metabolism, growth, proliferation,
and survival. PDK1 also has the ability to
autophosphorylate and is constitutively active in
mammalian cells. PDK1 is essential for normal embryo
development and is important in regulating cell volume.

>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.

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
tyrosine residues on protein substrates. The MAPKK
subfamily is part of a larger superfamily that includes
the catalytic domains of other protein serine/threonine
kinases, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. The mitogen-activated protein
(MAP) kinase signaling pathways are important mediators
of cellular responses to extracellular signals. The
pathways involve a triple kinase core cascade comprising
of the MAP kinase (MAPK), which is phosphorylated and
activated by a MAPK kinase (MAPKK or MKK), which itself
is phosphorylated and activated by a MAPK kinase kinase
(MAPKKK or MKKK). Members of this group include 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.

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

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.

inactive PKA holoenzyme is a heterotetramer composed of
two phosphorylated and active catalytic (C) subunits
with a dimer of regulatory (R) subunits. Activation is
achieved through the binding of the important second
messenger cAMP to the R subunits, which leads to the
dissociation of PKA into the R dimer and two active C

plays a role in the regulation of diverse processes such
as growth, development, memory, metabolism, gene

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.

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.

>gnl|CDD|173663 cd05572, STKc_cGK_PKG, Catalytic domain of the Protein
Serine/Threonine Kinase, cGMP-dependent protein kinase.
Serine/Threonine Kinases (STKs), cGMP-dependent protein
kinase (cGK or PKG) subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The cGK subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. Mammals have two cGK isoforms
from different genes, cGKI and cGKII. cGKI exists as two
splice variants, cGKI-alpha and cGKI-beta. cGK consists
of an N-terminal regulatory domain containing a
dimerization and an autoinhibitory pseudosubstrate
region, two cGMP-binding domains, and a C-terminal
catalytic domain. Binding of cGMP to both binding sites
releases the inhibition of the catalytic center by the
pseudosubstrate region, allowing autophosphorylation and
activation of the kinase. cGKI is a soluble protein
expressed in all smooth muscles, platelets, cerebellum,
and kidney. It is also expressed at lower concentrations
in other tissues. cGKII is a membrane-bound protein that
is most abundantly expressed in the intestine. It is
also present in the brain nuclei, adrenal cortex,
kidney, lung, and prostate. cGKI is involved in the
regulation of smooth muscle tone, smooth cell
proliferation, and platelet activation. cGKII plays a
role in the regulation of secretion, such as renin
secretion by the kidney and aldosterone secretion by the
adrenal. It also regulates bone growth and the circadian
rhythm.

Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase (CDK)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK-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. 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.

GTPase Rho, plays an important function during
cytokinesis and affects its contractile process.
CRIK-deficient mice show severe ataxia and epilepsy as a
result of abnormal cytokinesis and massive apoptosis in
neuronal precursors. A Down syndrome critical region
protein TTC3 interacts with CRIK and inhibits
CRIK-dependent neuronal differentiation and neurite
extension.

Serine/Threonine Kinases (STKs), Atypical Protein Kinase
C (aPKC) subfamily, catalytic (c) domain. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
aPKC 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. aPKCs only require
phosphatidylserine (PS) for activation. They contain a
C2-like region, instead of a calcium-binding (C2) region
found in classical PKCs, in their regulatory domain.
There are two aPKC isoforms, zeta and iota. aPKCs are
involved in many cellular functions including
proliferation, migration, apoptosis, polarity
maintenance and cytoskeletal regulation. They also play
a critical role in the regulation of glucose metabolism
and in the pathogenesis of type 2 diabetes.

STKs catalyze the transfer of the gamma-phosphoryl group

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

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.

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

(1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. There are four
cPKC isoforms, named alpha, betaI, betaII, and gamma.
The PKC beta isoforms (I and II), generated by
alternative splicing of a single gene, are
preferentially activated by hyperglycemia-induced DAG in
retinal tissues. This is implicated in diabetic
microangiopathy such as ischemia, neovascularization,
and abnormal vasodilator function. PKC-beta also plays
an important role in VEGF signaling. In addition,
glucose regulates proliferation in retinal endothelial
cells via PKC-betaI. PKC-beta is also being explored as
a therapeutic target in cancer. It contributes to tumor
formation and is involved in the tumor host mechanisms
of inflammation and angiogenesis.

Serine/Threonine Kinases (STKs), Nuclear Dbf2-Related
(NDR) kinase subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The NDR 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. NDR kinase contains an N-terminal regulatory
(NTR) domain and an insert within the catalytic domain
that contains an auto-inhibitory sequence. Like many
other AGC kinases, NDR kinase requires phosphorylation
at two sites, the activation loop (A-loop) and the
hydrophobic motif (HM), for activity. NDR kinases
regulate mitosis, cell growth, embryonic development,
and neurological processes. They are also required for
proper centrosome duplication. Higher eukaryotes contain
two NDR isoforms, NDR1 and NDR2. This subfamily also
contains fungal NDR-like kinases.

residues on protein substrates. The MSK subfamily is
part of a larger superfamily that includes the catalytic

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

MKKs or MAP2Ks), which in turn phosphorylate and
activate MAPKs during signaling cascades that are
important in mediating cellular responses to
extracellular signals. MEKK4 activates the c-Jun
N-terminal kinase (JNK) and p38 MAPK signaling pathways
by directly activating their respective MAPKKs,
MKK4/MKK7 and MKK3/MKK6. 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. MEKK4 also plays roles in
the re-polarization of the actin cytoskeleton in
response to osmotic stress, in the proper closure of the
neural tube, in cardiovascular development, and in
immune responses.

tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. This subfamily is composed of MST3, MST4,
STK25, Schizosaccharomyces pombe Nak1 and Sid1,
Saccharomyces cerevisiae sporulation-specific protein 1
(SPS1), and related proteins. Nak1 is required by
fission yeast for polarizing the tips of actin
cytoskeleton and is involved in cell growth, cell
separation, cell morphology and cell-cycle progression.
Sid1 is a component in the septation initiation network
(SIN) signaling pathway, and plays a role in
cytokinesis. SPS1 plays a role in regulating proteins
required for spore wall formation. MST4 plays a role in
mitogen-activated protein kinase (MAPK) signaling during
cytoskeletal rearrangement, morphogenesis, and
apoptosis. MST3 phosphorylates the STK NDR and may play
a role in cell cycle progression and cell morphology.
STK25 may play a role in the regulation of cell
migration and polarization.

PKB isoforms from different genes, PKB-alpha (or Akt1),
PKB-beta (or Akt2), and PKB-gamma (or Akt3). PKB
contains an N-terminal pleckstrin homology (PH) domain
and a C-terminal catalytic domain. PKB-gamma is
predominantly expressed in neuronal tissues. Mice
deficient in PKB-gamma show a reduction in brain weight
due to the decreases in cell size and cell number.
PKB-gamma has also been shown to be upregulated in
estrogen-deficient breast cancer cells,
androgen-independent prostate cancer cells, and primary
ovarian tumors. It acts as a key mediator in the genesis
of ovarian cancer.

They are activated by signaling inputs from
extracellular regulated kinase (ERK) and
phosphoinositide dependent kinase 1 (PDK1). ERK
phosphorylates and activates the CTD of RSK, serving as
a docking site for PDK1, which phosphorylates and
activates the NTD, which in turn phosphorylates all
known RSK substrates. RSKs act as downstream effectors
of mitogen-activated protein kinase (MAPK) and play key
roles in mitogen-activated cell growth, differentiation,

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.

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.

Serine/Threonine Kinase, Atypical Protein Kinase C iota.
Serine/Threonine Kinases (STKs), Atypical Protein
Kinase C (aPKC) subfamily, iota isoform, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The aPKC 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.
aPKCs only require phosphatidylserine (PS) for
activation. There are two aPKC isoforms, zeta and iota.
PKC-iota is directly implicated in carcinogenesis. It is
critical to oncogenic signaling mediated by Ras and
Bcr-Abl. The PKC-iota gene is the target of
tumor-specific gene amplification in many human cancers,
and has been identified as a human oncogene. In addition
to its role in transformed growth, PKC-iota also
promotes invasion, chemoresistance, and tumor cell
survival. Expression profiling of PKC-iota is a
prognostic marker of poor clinical outcome in several
human cancers. PKC-iota also plays a role in
establishing cell polarity, and has critical embryonic
functions.

catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The Nek3 subfamily is
one of a family of 11 different Neks (Nek1-11) that are
involved in cell cycle control. The Nek family is part
of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. Nek3 is primarily
localized in the cytoplasm and shows no cell
cycle-dependent changes in its activity. It is present
in the axons of neurons and affects morphogenesis and
polarity through its regulation of microtubule
acetylation. Nek3 modulates the signaling of the
prolactin receptor through its activation of Vav2 and
contributes to prolactin-mediated motility of breast
cancer cells.

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

The nPKC subfamily is part of a larger superfamily that

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

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.

protein kinase 4 (CDK4) and CDK6-like subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK4/6-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. 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. CDK4 and CDK6
partner with D-type cyclins to regulate the early G1
phase of the cell cycle. They are the first kinase
activated by mitogenic signals to release cells from the
G0 arrested state. CDK4 and CDK6 are both expressed
ubiquitously, associate with all three D cyclins (D1, D2
and D3), and phosphorylate the retinoblastoma (pRb)
protein. They are also regulated by the INK4 family of
inhibitors which associate with either the CDK alone or
the CDK/cyclin complex. CDK4 and CDK6 show differences
in subcellular localization, sensitivity to some
inhibitors, timing in activation, tumor selectivity, and
possibly substrate profiles. Although CDK4 and CDK6 seem
to show some redundancy, they also have discrete,
nonoverlapping functions. CDK6 plays an important role
in cell differentiation.

family GTPase-regulated kinases that serve as important

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. 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.

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. GRK6 is widely expressed in many tissues.
t is expressed as multiple splice variants with
different domain architectures. It is
post-translationally palmitoylated and localized in the
membrane. GRK6 plays important roles in the regulation
of dopamine, M3 muscarinic, opioid, and chemokine
receptor signaling. It also plays maladaptive roles in
addiction and Parkinson's disease. GRK6-deficient mice
exhibit altered dopamine receptor regulation, decreased
lymphocyte chemotaxis, and increased acute inflammation
and neutrophil chemotaxis.

GTPases. ROCK2 was the first identified target of
activated RhoA, and was found to play a role in stress
fiber and focal adhesion formation. It is prominently
expressed in the brain, heart, and skeletal muscles. It
is implicated in vascular and neurological disorders,
such as hypertension and vasospasm of the coronary and

cleavage, resulting in thrombin-induced microparticle
generation in response to cell activation. Mice
deficient in ROCK2 show intrauterine growth retardation

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. This subfamily is composed of CDK1 from higher
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.

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

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.

activated by a MAPK kinase kinase (MAPKKK or MKKK).
Members of this group include the MAPKKs Pek1/Skh1 from
Schizosaccharomyces pombe and MKK2 from Saccharomyces
cerevisiae, and related proteins. Both fission yeast
Pek1 and baker's yeast MKK2 are components of the cell
integrity MAPK pathway. In fission yeast, Pek1
phosphorylates and activates the MAPK Pmk1/Spm1 and is
regulated by the MAPKKK Mkh1. In baker's yeast, the
pathway involves the MAPK Slt2, the MAPKKs MKK1 and
MKK2, and the MAPKKK Bck1. The cell integrity MAPK
cascade is activated by multiple stress conditions, and
is essential in cell wall construction, morphogenesis,
cytokinesis, and ion homeostasis.

MAPKKK 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 group include the MAPKKKs
Schizosaccharomyces pombe Byr2, Saccharomyces cerevisiae
and Cryptococcus neoformans Ste11, and related proteins.
They contain an N-terminal SAM (sterile alpha-motif)
domain, which mediates protein-protein interaction, and
a C-terminal catalytic domain. MAPKKKs phosphorylate and
activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which
in turn phosphorylate and activate MAPKs during
signaling cascades that are important in mediating
cellular responses to extracellular signals. Fission
yeast Byr2 is regulated by Ras1. It responds to
pheromone signaling and controls mating through the MAPK
pathway. Budding yeast Ste11 functions in MAPK cascades
that regulate mating, high osmolarity glycerol, and
filamentous growth responses.

protein-coupled receptors (GPCRs), the largest
superfamily of cell surface receptors which regulate
some part of nearly all physiological functions.
Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. GRK4 has a limited tissue distribution. It
is mainly found in the testis, but is also present in
the cerebellum and kidney. It is expressed as multiple
splice variants with different domain architectures. It
is post-translationally palmitoylated and localized in
the membrane. GRK4 polymorphisms are associated with
hypertension and salt sensitivity, as they cause
hyperphosphorylation, desensitization, and
internalization of the dopamine 1 (D1) receptor while
increasing the expression of the angiotensin II type 1
receptor. GRK4 plays a crucial role in the D1 receptor
regulation of sodium excretion and blood pressure.

regulated by their cognate cyclins. Together, they are
involved in the control of cell-cycle progression,
transcription, and neuronal function. This subfamily is
composed of CDK9 and CDK12 from higher eukaryotes, yeast
BUR1, C-type plant CDKs (CdkC), and similar proteins.
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
cyclin BUR2. CDK12 is a unique CDK that contains an
arginine/serine-rich (RS) domain, which is predominantly
found in splicing factors. CDK12 interacts with cyclins
L1 and L2, and participates in regulating transcription
and alternative splicing.

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

Protein 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.

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.

Kinase, Mitogen-Activated Protein Kinase 15.
Serine/Threonine Kinases (STKs), Mitogen-Activated
Protein Kinase 15 (MAPK15) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAPK15 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. Human MAPK15 is also called
Extracellular signal Regulated Kinase 8 (ERK8) while the
rat protein is called ERK7. ERK7 and ERK8 display both
similar and different biochemical properties. They
autophosphorylate and activate themselves and do not
require upstream activating kinases. ERK7 is
constitutively active and is not affected by
extracellular stimuli whereas ERK8 shows low basal
activity and is activated by DNA-damaging agents. ERK7
and ERK8 also have different substrate profiles. Genome
analysis shows that they are orthologs with similar gene
structures. ERK7 and ERK 8 may be involved in the
signaling of some nuclear receptor transcription
factors. ERK7 regulates hormone-dependent degradation of
estrogen receptor alpha while ERK8 down-regulates the
transcriptional co-activation androgen and
glucocorticoid receptors.

Serine/Threonine Kinases (STKs), Myotonic Dystrophy
protein kinase (DMPK)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The DMPK-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. The DMPK-like subfamily is composed of DMPK
and DMPK-related cell division control protein 42
(Cdc42) binding kinase (MRCK). Three isoforms of MRCK
are known, named alpha, beta and gamma. The DMPK gene is
implicated in myotonic dystrophy 1 (DM1), an inherited
multisystemic disorder with symptoms that include muscle
hyperexcitability, progressive muscle weakness and
wasting, cataract development, testicular atrophy, and
cardiac conduction defects. The genetic basis for DM1 is
the mutational expansion of a CTG repeat in the 3'-UTR
of DMPK. DMPK is expressed in skeletal and cardiac
muscles, and in central nervous tissues. The functional
role of DMPK is not fully understood. It may play a role
in the signal transduction and homeostasis of calcium.
MRCK is activated via interaction with the small GTPase
Cdc42. MRCK/Cdc42 signaling mediates myosin-dependent
cell motility. MRCKgamma is expressed in heart and
skeletal muscles, unlike MRCKalpha and MRCKbeta, which
are expressed ubiquitously.

Serine/threonine kinases (STKs), MAP/ERK kinase kinase 3
(MEKK3)-like subfamily, catalytic (c) domain,
functionally uncharacterized subgroup 1. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP to

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

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.
PAK5 belongs to group II. Group II PAKs contain a PBD
(p21-binding domain) and a C-terminal catalytic domain,
but do not harbor an AID (autoinhibitory domain) or SH3
binding sites. PAK5 is mainly expressed in the brain. It
is not required for viability, but together with PAK6,
it is required for normal levels of locomotion and
activity, and for learning and memory. PAK5 cooperates
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
role in controlling the signaling of Raf-1, an effector
of Ras, at the mitochondria.

synaptic plasticity and learning. CDK5 also participates
in protecting against cell death and promoting
angiogenesis. Impaired CDK5 activity is implicated in
Alzheimer's disease, amyotrophic lateral sclerosis,
Parkinson's disease, Huntington's disease and acute
neuronal injury.

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.

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

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

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.

Kinase, Cyclin-Dependent protein Kinase 6.
Serine/Threonine Kinases (STKs), Cyclin-dependent
protein kinase 6 (CDK6) subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The CDK6 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. 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.

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. GRK3 (also known as beta-adrenergic
receptor kinase 2) is widely expressed in many tissues.
GRK3-deficient mice show a lack of olfactory receptor
desensitization and altered regulation of the M2
muscarinic airway. GRK3 is involved in modulating the
cholinergic response of airway smooth muscles. It also
plays a role in dopamine receptor regulation. GRK3
promoter polymorphisms may be associated with bipolar
disorder.

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

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.

of ERK2 is embryonically lethal. The MAPK, Fus3,
regulates yeast mating processes including

Serine/Threonine Kinase, p21-activated kinase 3.
Serine/threonine kinases (STKs), p21-activated kinase
(PAK) 3, 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.
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.

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.

signaling pathways are important mediators of cellular

a triple kinase core cascade comprising the MAP kinase
(MAPK), which is phosphorylated and activated by a MAPK
kinase (MAPKK or MKK), which itself is phosphorylated
and activated by a MAPK kinase kinase (MAPKKK or MKKK).
MKK7 is a dual-specificity PK that phosphorylates and
activates its downstream target, c-Jun N-terminal kinase
(JNK), on specific threonine and tyrosine residues.
Although MKK7 is capable of dual phosphorylation, it
prefers to phosphorylate the threonine residue of JNK.
Thus, optimal activation of JNK requires both MKK4 (not
included in this subfamily) and MKK7. MKK7 is primarily
activated by cytokines. MKK7 is essential for liver
formation during embryogenesis. It plays roles in G2/M
cell cycle arrest and cell growth. In addition, it is
involved in the control of programmed cell death, which
is crucial in oncogenesis, cancer chemoresistance, and
antagonism to TNFalpha-induced killing, through its
inhibition by Gadd45beta and the subsequent suppression
of the JNK cascade.

Serine/threonine kinases (STKs), p21-activated kinase
(PAK) 2, 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.
PAK2 belongs to group I. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). PAK2 plays a
role in pro-apoptotic signaling. It is cleaved and
activated by caspases leading to morphological changes
during apoptosis. PAK2 is also activated in response to
a variety of stresses including DNA damage,
hyperosmolarity, serum starvation, and contact
inhibition, and may play a role in coordinating the
stress response. PAK2 also contributes to cancer cell
invasion through a mechanism distinct from that of PAK1.

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). MEK1
and MEK2 are dual-specificity PKs that phosphorylate and
activate the downstream targets, ERK(extracellular

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 MEK1/2, and finally to ERK1/2. The ERK
cascade plays an important role in cell proliferation,
differentiation, oncogenic transformation, and cell

under certain conditions. This cascade has also been
implicated in synaptic plasticity, migration,
morphological determination, and stress response
immunological reactions. Gain-of-function mutations in
genes encoding ERK cascade proteins, including MEK1/2,
cause cardiofaciocutaneous (CFC) syndrome, a condition
leading to multiple congenital anomalies and mental

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. 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.

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

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.

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.

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

STK involved in many cellular signaling cascades
including MAPK, antigen receptor, apoptosis, growth

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

their cognate cyclins. Together, CDKs and cyclins are
involved in the control of cell-cycle progression,
transcription, and neuronal function. PFTAIRE-1 is
widely expressed except in the spleen and thymus. It is
highly expressed in the brain, heart, pancreas, testis,

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.

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.

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.

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).

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

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.

Serine/threonine kinases (STKs), thousand-and-one amino
acids (TAO) 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

phosphotransferase, choline kinase, and phosphoinositide
3-kinase. TAO proteins possess mitogen-activated protein
kinase (MAPK) kinase kinase (MAPKKK or MAP3K or MKKK)
activity. They activate the MAPKs, 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. MAPK
signaling cascades are important in mediating cellular
responses to extracellular signals. Vertebrates contain
three TAO subfamily members, named TAO1, TAO2, and TAO3.

a member of the Syk subfamily of kinases, which are
cytoplasmic (or nonreceptor) tyr kinases containing two
Src homology 2 (SH2) domains N-terminal to the catalytic
tyr kinase domain. Zap-70 is primarily expressed in
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.

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

transcription of target genes. In prostate cancer cells,
NLK is involved in regulating androgen receptor-mediated
transcription and its expression is altered during
cancer progression.

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.

from the spleen, and its function in hematopoietic cells
is well-established. Syk is involved in the signaling
downstream of activated receptors (including B-cell and
Fc receptors) that contain ITAMs (immunoreceptor tyr
activation motifs), leading to processes such as cell
proliferation, differentiation, survival, adhesion,
migration, and phagocytosis. More recently, Syk
expression has been detected in other cell types
(including epithelial cells, vascular endothelial cells,
neurons, hepatocytes, and melanocytes), suggesting a
variety of biological functions in non-immune cells. Syk
plays a critical role in maintaining vascular integrity
and in wound healing during embryogenesis. It also
regulates Vav3, which is important in osteoclast
function including bone development. In breast
epithelial cells, where Syk acts as a negative regulator
for epidermal growth factor receptor (EGFR) signaling,
loss of Syk expression is associated with abnormal
proliferation during cancer development suggesting a
potential role as a tumor suppressor. In mice, Syk has
been shown to inhibit malignant transformation of
mammary epithelial cells induced with murine mammary
tumor virus (MMTV).

larger superfamily that includes the catalytic domains
of other kinases such as protein serine/threonine

(PI3K). PTKs catalyze the transfer of the
gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. Lyn 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. 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.

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).

(Fujinami poultry sarcoma) were first isolated from
tumor-causing retroviruses. The viral oncogenes encode
chimeric Fes proteins consisting of Gag sequences at the
N-termini, resulting in unregulated tyr kinase activity.
Fes and Fer kinases play roles in haematopoiesis,
inflammation and immunity, growth factor signaling,
cytoskeletal regulation, cell migration and adhesion,
and the regulation of cell-cell interactions. Fes and
Fer show redundancy in their biological functions.

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.

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.

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.

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

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.

(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)

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 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.

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).

such as protein serine/threonine kinases, RIO kinases,
and phosphoinositide 3-kinase (PI3K). PTKs catalyze the

alpha is a receptor tyr kinase (RTK) containing an
extracellular ligand-binding region with five
immunoglobulin-like domains, a transmembrane segment,
and an intracellular catalytic domain. The binding to
its ligands, the PDGFs, leads to receptor dimerization,
trans phosphorylation and activation, and intracellular
signaling. PDGFR alpha forms homodimers or heterodimers
with PDGFR beta, depending on the nature of the PDGF
ligand. PDGF-AA, PDGF-AB, and PDGF-CC induce PDGFR alpha
homodimerization. PDGFR signaling plays many roles in
normal embryonic development and adult physiology. PDGFR
alpha signaling is important in the formation of lung
alveoli, intestinal villi, mesenchymal dermis, and hair
follicles, as well as in the development of
oligodendrocytes, retinal astrocytes, neural crest
cells, and testicular cells. Aberrant PDGFR alpha
expression is associated with some human cancers.
Mutations in PDGFR alpha have been found within a subset
of gastrointestinal stromal tumors (GISTs). An active
fusion protein FIP1L1-PDGFR alpha, derived from
interstitial deletion, is associated with idiopathic
hypereosinophilic syndrome (HES) and chronic
eosinophilic leukemia (CEL).

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

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

a distinct cell-type pattern of expression. The function
of Tec kinases in lymphoid cells have been studied

Serine/Threonine Kinases, RPK118 and similar proteins.
Serine/Threonine Kinases (STKs), RPK118-like subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The RPK118-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 show similarity to
human RPK118, which contains an N-terminal Phox homology
(PX) domain, a Microtubule Interacting and Trafficking
(MIT) domain, and a kinase domain containing a long
insert. Also included in the family is human RPK60 (or
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.

transcription, and neuronal function. BUR1, also called
SGV1, is a yeast Cyclin-Dependent protein Kinase (CDK)
that is functionally equivalent to mammalian CDK9. It
associates with the cyclin BUR2. BUR genes were
orginally identified in a genetic screen as factors
involved in general transcription. The BUR1/BUR2 complex
phosphorylates the C-terminal domain of RNA polymerase
II. In addition, this complex regulates histone
modification by phosporylating Rad6 and mediating the
association of the Paf1 complex with chromatin.

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

subfamily proteins are cytoplasmic (or nonreceptor) tyr
kinases containing an N-terminal region with FCH
(Fes/Fer/CIP4 homology) and coiled-coil domains,
followed by a SH2 domain, and a C-terminal catalytic
domain. The genes for Fes (feline sarcoma) and Fps
(Fujinami poultry sarcoma) were first isolated from
tumor-causing retroviruses. The viral oncogenes encode
chimeric Fes proteins consisting of Gag sequences at the
N-termini, resulting in unregulated tyr kinase activity.
Fes kinase is expressed in myeloid, vascular
endothelial, epithelial, and neuronal cells. It plays
important roles in cell growth and differentiation,
angiogenesis, inflammation and immunity, and
cytoskeletal regulation. A recent study implicates Fes
kinase as a tumor suppressor in colorectal cancer.

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

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. p38gamma, also called MAPK12, is predominantly
expressed in skeletal muscle. Unlike p38alpha and
p38beta, p38gamma is insensitive to pyridinylimidazoles.
It displays an antagonizing function compared to
p38alpha. p38gamma inhibits, while p38alpha stimulates,
c-Jun phosphorylation and AP-1 mediated transcription.
p38gamma also plays a role in the signaling between Ras
and the estrogen receptor and has been implicated to
increase cell invasion and breast cancer progression. In
Xenopus, p38gamma is critical in the meiotic maturation
of oocytes.

part of the FGFR subfamily, which are receptor tyr
kinases (RTKs) containing an extracellular
ligand-binding region with three immunoglobulin-like
domains, a transmembrane segment, and an intracellular

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

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.

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

PDGFR subfamily members are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
five immunoglobulin-like domains, a transmembrane
segment, and an intracellular catalytic domain. PDGFR
kinase domains are autoinhibited by their juxtamembrane
regions containing tyr residues. The binding to their
ligands leads to receptor dimerization, trans
phosphorylation and activation, and intracellular
signaling. PDGFR subfamily receptors are important in
the development of a variety of cells. PDGFRs are
expressed in a many cells including fibroblasts,
neurons, endometrial cells, mammary epithelial cells,
and vascular smooth muscle cells. PDGFR signaling is
critical in normal embryonic development, angiogenesis,
and wound healing. PDGFRs transduce mitogenic signals
for connective tissue cells and are important for cell
shape and motility. Kit is important in the development
of melanocytes, germ cells, mast cells, hematopoietic
stem cells, the interstitial cells of Cajal, and the
pacemaker cells of the GI tract. CSF-1R signaling is
critical in the regulation of macrophages and
osteoclasts. Mammalian FLT3 plays an important role in
the survival, proliferation, and differentiation of stem
cells.

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

(HER, ErbB) subfamily members include EGFR (HER1,

similar proteins. The PTKc family is part of a larger

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.

(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.

most class EphA receptors including EphA3, EphA4, EphA5,

of other kinases such as protein serine/threonine

(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.

domains, a transmembrane segment, and an intracellular

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

there is only one splice form of FGFR4. It binds FGF1,
FGF2, FGF6, FGF19, and FGF23. FGF19 is a selective
ligand for FGFR4. Although disruption of FGFR4 in mice
causes no obvious phenotype, in vivo inhibition of FGFR4
in cultured skeletal muscle cells resulted in an arrest
of muscle progenitor differentiation. FGF6 and FGFR4 are
uniquely expressed in myofibers and satellite cells.
FGF6/FGFR4 signaling appears to play a key role in the
regulation of muscle regeneration. A polymorphism in
FGFR4 is found in head and neck squamous cell carcinoma.

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

of STKs that are regulated by their cognate cyclins.
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.

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.

Kinases, Receptor tyrosine kinase-like Orphan Receptors.
Protein Tyrosine Kinase (PTK) family; Receptor tyrosine
kinase-like Orphan Receptor (Ror) subfamily; catalytic
(c) domain. The Ror subfamily consists of Ror1, Ror2,
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. 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. Ror kinases
are expressed in many tissues during development. They
play important roles in bone and heart formation.
Mutations in human Ror2 result in two different bone
development genetic disorders, recessive Robinow
syndrome and brachydactyly type B. Drosophila Ror is
expressed only in the developing nervous system during
neurite outgrowth and neuronal differentiation,
suggesting a role for Drosophila Ror in neural
development. More recently, mouse Ror1 and Ror2 have
also been found to play an important role in regulating
neurite growth in central neurons. Ror1 and Ror2 are
believed to have some overlapping and redundant
functions.

also called c-Fms, is a member of the Platelet Derived
Growth Factor Receptor (PDGFR) subfamily of proteins,
which are receptor tyr kinases (RTKs) containing an
extracellular ligand-binding region with five
immunoglobulin-like domains, a transmembrane segment,
and an intracellular catalytic domain. The binding of
CSF-1R to its ligand, CSF-1, leads to receptor
dimerization, trans phosphorylation and activation, and
intracellular signaling. CSF-1R signaling is critical in
the regulation of macrophages and osteoclasts. It leads
to increases in gene transcription and protein
translation, and induces cytoskeletal remodeling. CSF-1R
signaling leads to a variety of cellular responses
including survival, proliferation, and differentiation
of target cells. It plays an important role in innate
immunity, tissue development and function, and the
pathogenesis of some diseases including atherosclerosis
and cancer. CSF-1R signaling is also implicated in
mammary gland development during pregnancy and
lactation. Aberrant CSF-1/CSF-1R expression correlates
with tumor cell invasiveness, poor clinical prognosis,
and bone metastasis in breast cancer. Although the
structure of the human CSF-1R catalytic domain is known,
it is excluded from this specific alignment model
because it contains a deletion in its sequence.

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.

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

subfamily kinases are cytoplasmic (or nonreceptor) tyr
kinases containing the Src homology domains, SH3 and
SH2, N-terminal to the catalytic tyr kinase domain. They
negatively regulate the activity of Src kinases that are
anchored to the plasma membrane. Chk is also referred to
as megakaryocyte-associated tyrosine kinase (Matk). To
inhibit Src kinases, Chk is translocated to the membrane
via binding to specific transmembrane proteins,
G-proteins, or adaptor proteins near the membrane. Chk
inhibit Src kinases using a noncatalytic mechanism by
simply binding to them. As a negative regulator of Src
kinases, Chk may play important roles in cell
proliferation, survival, and differentiation, and
consequently, in cancer development and progression. Chk
is expressed in brain and hematopoietic cells. Studies
in mice reveal that Chk is not functionally redundant
with Csk and that it plays an important role as a
regulator of immune responses. Chk also plays a role in
neural differentiation in a manner independent of Src by
enhancing Mapk activation via Ras-mediated signaling.

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).

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.

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

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.

Aatyk proteins are mostly receptor tyr kinases (RTKs)

not contain a transmembrane segment and is a cytoplasmic

differentiation, nerve growth factor (NGF) signaling,
apoptosis, and spermatogenesis.

and Choline Kinase (ChoK) family. The APH/ChoK family 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). The family is composed
of APH, ChoK, ethanolamine kinase (ETNK), macrolide
2'-phosphotransferase (MPH2'), an unusual homoserine
kinase, and uncharacterized proteins with similarity to
the N-terminal domain of acyl-CoA dehydrogenase 10
(ACAD10). The members of this family catalyze the
transfer of the gamma-phosphoryl group from ATP (or CTP)
to small molecule substrates such as aminoglycosides,
macrolides, choline, ethanolamine, and homoserine.
Phosphorylation of the antibiotics, aminoglycosides and
macrolides, leads to their inactivation and to bacterial
antibiotic resistance. Phosphorylation of choline,
ethanolamine, and homoserine serves as precursors to the
synthesis of important biological compounds, such as the
major phospholipids, phosphatidylcholine and
phosphatidylethanolamine and the amino acids, threonine,
methionine, and isoleucine.

Protein Tyrosine Kinases, Janus kinases 2 and 3.
Protein Tyrosine Kinase (PTK) family; Janus kinase 2
(Jak2) and Jak3; pseudokinase domain (repeat 1). The
PTKc (catalytic domain) family to which this subfamily
belongs, is part of a larger superfamily that includes
the catalytic domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. 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 tyr kinase domain. The pseudokinase
domain shows similarity to tyr kinases but lacks crucial
residues for catalytic activity and ATP binding. It
modulates the kinase activity of the C-terminal
catalytic domain. Jaks are crucial for cytokine receptor
signaling. They are activated by autophosphorylation
upon cytokine-induced receptor aggregation, and
subsequently trigger downstream signaling events such as
the phosphorylation of signal transducers and activators
of transcription (STATs). Jak2 is widely expressed in
many tissues while Jak3 is expressed only in
hematopoietic cells. Jak2 is essential for the signaling
of hormone-like cytokines such as growth hormone,
erythropoietin, thrombopoietin, and prolactin, as well
as some IFNs and cytokines that signal through the IL-3
and gp130 receptors. Jak3 binds the shared receptor
subunit common gamma chain and thus, is essential in the
signaling of cytokines that use it such as IL-2, IL-4,
IL-7, IL-9, IL-15, and IL-21. Disruption of Jak2 in mice
results in an embryonic lethal phenotype with multiple
defects including erythropoietic and cardiac
abnormalities. It is the only Jak gene that results in a
lethal phenotype when disrupted in mice. A mutation in
the pseudokinase domain of Jak2, V617F, is present in
many myeloproliferative diseases, including almost all
patients with polycythemia vera, and 50% of patients
with essential thrombocytosis and myelofibrosis. Jak3 is
important in lymphoid development and myeloid cell
differentiation. Inactivating mutations in Jak3 have
been reported in humans with severe combined
immunodeficiency (SCID).

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

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.

specifically expressed in endothelial cells and
hematopoietic stem cells. The angiopoietins (Ang-1 to
Ang-4) serve as ligands for Tie2, while no specific

beta is a receptor tyr kinase (RTK) containing an
extracellular ligand-binding region with five
immunoglobulin-like domains, a transmembrane segment,
and an intracellular catalytic domain. The binding to
its ligands, the PDGFs, leads to receptor dimerization,
trans phosphorylation and activation, and intracellular
signaling. PDGFR beta forms homodimers or heterodimers
with PDGFR alpha, depending on the nature of the PDGF
ligand. PDGF-BB and PDGF-DD induce PDGFR beta
homodimerization. PDGFR signaling plays many roles in
normal embryonic development and adult physiology. PDGFR
beta signaling leads to a variety of cellular effects
including the stimulation of cell growth and chemotaxis,
as well as the inhibition of apoptosis and GAP
junctional communication. It is critical in normal
angiogenesis as it is involved in the recruitment of
pericytes and smooth muscle cells essential for vessel
stability. Aberrant PDGFR beta expression is associated

phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. EGFR
(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
with other therapies for the treatment of colorectal
cancer and non-small cell lung carcinoma (NSCLC). The
small molecule inhibitors Gefitinib (Iressa) and
Erlotinib (Tarceva), already used for NSCLC, are
undergoing clinical trials for other types of cancer
including gastrointestinal, breast, head and neck, and
bladder.

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.

C-terminal tyr kinase domain. The pseudokinase domain
shows similarity to tyr kinases but lacks crucial
residues for catalytic activity and ATP binding. It
modulates the kinase activity of the C-terminal
catalytic domain. Jaks are crucial for cytokine receptor
signaling. They are activated by autophosphorylation
upon cytokine-induced receptor aggregation, and
subsequently trigger downstream signaling events such as
the phosphorylation of signal transducers and activators
of transcription (STATs). Tyk2 is widely expressed in
many tissues. It is involved in signaling via the
cytokine receptors IFN-alphabeta, IL-6, IL-10, IL-12,
IL-13, and IL-23. It mediates cell surface urokinase
receptor (uPAR) signaling and plays a role in modulating
vascular smooth muscle cell (VSMC) functional behavior
in response to injury. Tyk2 is also important in
dendritic cell function and T helper (Th)1 cell
differentiation. A homozygous mutation of Tyk2 was found
in a patient with hyper-IgE syndrome (HIES), a primary
immunodeficiency characterized by recurrent skin
abscesses, pneumonia, and elevated serum IgE. This
suggests that Tyk2 may play important roles in multiple
cytokine signaling involved in innate and adaptive
immunity.

pseudokinase domain, and a C-terminal catalytic tyr
kinase domain. The pseudokinase domain shows similarity
to tyr kinases but lacks crucial residues for catalytic
activity and ATP binding. It modulates the kinase
activity of the C-terminal catalytic domain. 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.

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

proto-oncogene c-ros encodes an orphan receptor tyr
kinase (RTK) with an unknown ligand. RTKs contain an
extracellular ligand-binding domain, a transmembrane

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

Sevenless, is required for the specification of the R7
photoreceptor cell during eye development.

leukocytes, where it facilitates cell adhesion,
migration, maturation, and cytokine production.

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.

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

to their ligands leads to receptor dimerization,
autophosphorylation, activation, and intracellular
signaling. Met binds to the ligand, hepatocyte growth
factor/scatter factor (HGF/SF), and is also called the
HGF receptor. HGF/Met signaling plays a role in growth,
transformation, cell motility, invasion, metastasis,
angiogenesis, wound healing, and tissue regeneration.
Aberrant expression of Met through mutations or gene
amplification is associated with many human cancers
including hereditary papillary renal and gastric
carcinomas. The ligand for Ron is macrophage stimulating
protein (MSP). Ron signaling is important in regulating
cell motility, adhesion, proliferation, and apoptosis.

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,

Tyrosine Kinase. Protein Tyrosine Kinase (PTK) family;
Anaplastic Lymphoma Kinase (ALK) and Leukocyte Tyrosine
(tyr) Kinase (LTK); 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 tyr
residues in protein substrates. ALK and LTK are orphan
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.

(STKs), protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and

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.

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 present
in archaea, bacteria and eukaryotes. Serine kinases
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine residues in protein substrates. RIO
kinases contain a kinase catalytic signature, but
otherwise show very little sequence similarity to
typical PKs. The RIO catalytic domain is truncated
compared to the catalytic domains of typical PKs, with
deletions of the loops responsible for substrate
binding. Most organisms contain at least two RIO
kinases, RIO1 and RIO2. A third protein, RIO3, is
present in multicellular eukaryotes. In yeast, RIO1 and
RIO2 are essential for survival. They function as
non-ribosomal factors necessary for late 18S rRNA
processing. RIO1 is also required for proper cell cycle
progression and chromosome maintenance. The biological
substrates for RIO kinases are still unknown.

proteins, catalytic domain. The RIO kinase catalytic
domain family is part 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. RIO1 is present
in archaea, bacteria and eukaryotes. In addition, RIO3
is present in multicellular eukaryotes. RIO1 is
essential for survival and is required for 18S rRNA
processing, proper cell cycle progression and chromosome
maintenance. The biological substrates for RIO1 are
unknown. The function of RIO3 is also unknown.

>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.
