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

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

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

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

subfamily is part of a larger superfamily that includes

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.

>gnl|CDD|173624 cd00192, PTKc, Catalytic domain of Protein Tyrosine Kinases.
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.

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.

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.

Mitosis gene A (NIMA)-related kinase 2 (Nek2) subfamily,

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

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

Protein Kinase, Mitogen-Activated Protein Kinase Kinase.
Protein kinases (PKs), MAP kinase kinase (MAPKK)
subfamily, catalytic (c) domain. PKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine or tyrosine residues on protein
substrates. The 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 the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK or MAP2K), which itself is phosphorylated
and activated by a MAPK kinase kinase (MAPKKK or MKKK or
MAP3K). MAPKKs are dual-specificity PKs that
phosphorylate their downstream targets, MAPKs, at
specific threonine and tyrosine residues. There are
three MAPK subfamilies: extracellular signal-regulated
kinase (ERK), c-Jun N-terminal kinase (JNK), and p38. In
mammalian cells, there are seven MAPKKs (named MKK1-7)
and 20 MAPKKKs. Each MAPK subfamily can be activated by
at least two cognate MAPKKs and by multiple MAPKKKs.

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

of STKs that are regulated by their cognate cyclins.
Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. MAPKs
serve as important mediators of cellular responses to
extracellular signals. They control critical cellular
functions including differentiation, proliferation,
migration, and apoptosis. They are also implicated in
the pathogenesis of many diseases including multiple
types of cancer, stroke, diabetes, and chronic
inflammation.

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

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

>gnl|CDD|173734 cd07830, STKc_MAK_like, Catalytic domain of Male germ
cell-Associated Kinase-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Male germ
cell-Associated Kinase (MAK)-like subfamily, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAK-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. This subfamily is composed of human MAK and
MAK-related kinase (MRK), Saccharomyces cerevisiae
Ime2p, Schizosaccharomyces pombe Mei4-dependent protein
3 (Mde3) and Pit1, Caenorhabditis elegans dyf-5,
Arabidopsis thaliana MHK, and similar proteins. These
proteins play important roles during meiosis. MAK is
highly expressed in testicular cells specifically in the
meiotic phase, but is not essential for spermatogenesis
and fertility. It functions as a coactivator of the
androgen receptor in prostate cells. MRK, also called
Intestinal Cell Kinase (ICK), is expressed ubiquitously,
with highest expression in the ovary and uterus. A
missense mutation in MRK causes
endocrine-cerebro-osteodysplasia (ECO), suggesting that
this protein plays an important role in the development
of many organs. MAK and MRK may be involved in
regulating cell cycle and cell fate. Ime2p is a
meiosis-specific kinase that is important during meiotic
initiation and during the later stages of meiosis. Mde3
functions downstream of the transcription factor Mei-4
which is essential for meiotic prophase I.

also facilitates Wnt signaling in B cells, and may
therefore be implicated in the control of cell fate,

extracellular ligand-binding domain, a transmembrane
region, and an intracellular tyr kinase domain. RTKs are
usually activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain. C-ros is
expressed in embryonic cells of the kidney, intestine
and lung, but disappears soon after birth. It persists
only in the adult epididymis. Male mice bearing inactive
mutations of c-ros lack the initial segment of the
epididymis and are infertile. The Drosophila protein,
Sevenless, is required for the specification of the R7

>gnl|CDD|132956 cd06625, STKc_MEKK3_like, Catalytic domain of MAP/ERK kinase kinase
3-like Protein Serine/Threonine Kinases.
Serine/threonine kinases (STKs), MAP/ERK kinase kinase 3
(MEKK3)-like subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The 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. This subfamily is composed of
MEKK3, MEKK2, and related proteins, all containing an
N-terminal PB1 domain, which mediates oligomerization,
and a C-terminal catalytic domain. MEKK2 and MEKK3 are
mitogen-activated protein kinase (MAPK) kinase kinases
(MAPKKKs or MKKKs or MAP3Ks), proteins that
phosphorylate and activate MAPK kinases (MAPKKs or MKKs
or MAP2Ks), which in turn phosphorylate and activate
MAPKs during signaling cascades that are important in
mediating cellular responses to extracellular signals.
MEKK2 and MEKK3 activate MEK5 (also called MKK5), which
activates extracellular signal-regulated kinase 5
(ERK5). The ERK5 cascade plays roles in promoting cell
proliferation, differentiation, neuronal survival, and
neuroprotection. MEKK3 plays an essential role in
embryonic angiogenesis and early heart development.
MEKK2 and MEKK3 can also activate the MAPKs, c-Jun
N-terminal kinase (JNK) and p38, through their
respective MAPKKs.

kinases (STKs), mitogen-activated protein kinase (MAPK)
kinase kinase (MAPKKK) subfamily, fungal Byr2-like
proteins, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
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.

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

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.

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.

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.

part of a larger superfamily that includes the catalytic

RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. PKCs are
classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
structural characteristics of their regulatory domain.
PKCs undergo three phosphorylations in order to take
mature forms. In addition, classical PKCs depend on
calcium, DAG (1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. Novel PKCs are
calcium-independent, but require DAG and PS for
activity, while atypical PKCs only require PS. PKCs
phosphorylate and modify the activities of a wide
variety of cellular proteins including receptors,
enzymes, cytoskeletal proteins, transcription factors,
and other kinases. They play a central role in signal
transduction pathways that regulate cell migration and
polarity, proliferation, differentiation, and apoptosis.
Also included in this subfamily are the PKC-like
proteins, called PKNs.

subfamily members include Src, Lck, Hck, Blk, Lyn, Fgr,
Fyn, Yrk, and Yes. The PTKc family is part of a larger
superfamily that includes the catalytic domains of other
kinases such as protein serine/threonine kinases, RIO
kinases, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
Src (or c-Src) proteins are cytoplasmic (or
non-receptor) tyr kinases which are anchored to the
plasma membrane. They contain an N-terminal SH4 domain
with a myristoylation site, followed by SH3 and SH2
domains, a tyr kinase domain, and a regulatory
C-terminal region containing a conserved tyr. They are
activated by autophosphorylation at the tyr kinase
domain, but are negatively regulated by phosphorylation
at the C-terminal tyr by Csk (C-terminal Src Kinase).
Src proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. They were identified as the first
proto-oncogene products, and they regulate cell
adhesion, invasion, and motility in cancer cells and
tumor vasculature, contributing to cancer progression
and metastasis. Src kinases are overexpressed in a
variety of human cancers, making them attractive targets
for therapy. They are also implicated in acute
inflammatory responses and osteoclast function. Src,
Fyn, Yes, and Yrk are widely expressed, while Blk, Lck,
Hck, Fgr, and Lyn show a limited expression pattern.

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.

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. Budding
yeast Bck1 is part of the cell integrity MAPK pathway,
which is activated by stresses and aggressions to the
cell wall. The MAPKKK Bck1, MAPKKs Mkk1 and Mkk2, and
the MAPK Slt2 make up the cascade that is important in
the maintenance of cell wall homeostasis. Fission yeast
Mkh1 is involved in MAPK cascades regulating cell
morphology, cell wall integrity, salt resistance, and

myosin-like Protein Serine/Threonine Kinases.
Serine/threonine kinases (STKs), Class III myosin-like
subfamily, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
class III myosin-like subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. Class III myosins are motor
proteins with an N-terminal kinase catalytic domain and
a C-terminal actin-binding motor domain. Class III
myosins are present in the photoreceptors of
invertebrates and vertebrates and in the auditory hair
cells of mammals. The kinase domain of myosin III can
phosphorylate several cytoskeletal proteins,
conventional myosin regulatory light chains, and can
autophosphorylate the C-terminal motor domain. Myosin
III may play an important role in maintaining the
structural integrity of photoreceptor cell microvilli.
It may also function as a cargo carrier during
light-dependent translocation, in photoreceptor cells,
of proteins such as transducin and arrestin. The
Drosophila class III myosin, called NinaC (Neither
inactivation nor afterpotential protein C), is critical
in normal adaptation and termination of photoresponse.
Vertebrates contain two isoforms of class III myosin,
IIIA and IIIB. This subfamily also includes mammalian
NIK-like embryo-specific kinase (NESK), Traf2- and
Nck-interacting kinase (TNIK), mitogen-activated protein
kinase (MAPK) kinase kinase kinase 4 (MAPKKKK4 or
MAP4K4) and MAPKKKK6 (or MAP4K6). MAP4Ks are involved in
some MAPK signaling pathways by activating a MAPK kinase
kinase (MAPKKK or MAP3K or MKKK). Each MAPK cascade is
activated either by a small GTP-binding protein or by an
adaptor protein, which transmits the signal either
directly to a MAP3K to start the triple kinase core
cascade or indirectly through a mediator kinase, a
MAP4K. MAPK signaling cascades are important in
mediating cellular responses to extracellular signals.

mitogen-activated protein (MAP) kinase signaling
pathways are important mediators of cellular responses
to extracellular signals. The pathways involve a triple
kinase core cascade comprising the MAP kinase (MAPK),
which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK), which itself is phosphorylated and
activated by a MAPK kinase kinase (MAPKKK or MKKK). MEK1
and MEK2 are dual-specificity PKs that phosphorylate and
activate the downstream targets, ERK(extracellular
signal-regulated kinase) 1 and ERK2, on specific
threonine and tyrosine residues. The ERK cascade starts
with extracellular signals including growth factors,
hormones, and neurotransmitters, which act through
receptors and ion channels to initiate intracellular
signaling that leads to the activation at the MAPKKK
(Raf-1 or MOS) level, which leads to the transmission of
signals to MEK1/2, and finally to ERK1/2. The ERK
cascade plays an important role in cell proliferation,
differentiation, oncogenic transformation, and cell
cycle control, as well as in apoptosis and cell survival
under certain conditions. 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
retardation in patients.

kinase (RTK) containing an extracellular region, a
transmembrane segment, and an intracellular catalytic
domain. The extracellular region contains an
immunoglobulin (Ig)-like domain, three epidermal growth
factor (EGF)-like domains, a second Ig-like domain, and
three fibronectin type III repeats. Tie2 is expressed
mainly in endothelial cells and hematopoietic stem
cells. It is also found in a subset of tumor-associated
monocytes and eosinophils. The angiopoietins (Ang-1 to
Ang-4) serve as ligands for Tie2. The binding of Ang-1
to Tie2 leads to receptor autophosphorylation and
activation, promoting cell migration and survival. In
contrast, Ang-2 binding to Tie2 does not result in the
same response, suggesting that Ang-2 may function as an
antagonist. Tie2 signaling plays key regulatory roles in
vascular integrity and quiescence, and in inflammation.

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

GRK3-deficient mice show a lack of olfactory receptor
desensitization and altered regulation of the M2

cholinergic response of airway smooth muscles. It also
plays a role in dopamine receptor regulation. GRK3
promoter polymorphisms may be associated with bipolar
disorder.

activation is associated with the induction of cell
death. Mice deficient in MKK4 die during embryogenesis
and display anemia, severe liver hemorrhage, and
abnormal hepatogenesis. MKK4 may also play roles in the

Kinase, MAP/ERK Kinase 1. Protein kinases (PKs),
MAP/ERK kinase (MEK) 1 subfamily, catalytic (c) domain.
PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on
protein substrates. The MEK subfamily is part of a
larger superfamily that includes the catalytic domains
of other protein serine/threonine kinases, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. The mitogen-activated protein (MAP) kinase
signaling pathways are important mediators of cellular
responses to extracellular signals. The pathways involve
a triple kinase core cascade comprising the MAP kinase
(MAPK), which is phosphorylated and activated by a MAPK
kinase (MAPKK or MKK), which itself is phosphorylated
and activated by a MAPK kinase kinase (MAPKKK or MKKK).
MEK1 is a dual-specificity PK that phosphorylates and
activates the downstream targets, extracellular
signal-regulated kinase (ERK) 1 and ERK2, on specific
threonine and tyrosine residues. The ERK cascade starts
with extracellular signals including growth factors,
hormones, and neurotransmitters, which act through
receptors and ion channels to initiate intracellular
signaling that leads to the activation at the MAPKKK
(Raf-1 or MOS) level, which leads to the transmission of
signals to MEK1, and finally to ERK1/2. The ERK cascade
plays an important role in cell proliferation,
differentiation, oncogenic transformation, and cell
cycle control, as well as in apoptosis and cell survival
under certain conditions. Gain-of-function mutations in
genes encoding ERK cascade proteins, including MEK1,
cause cardiofaciocutaneous (CFC) syndrome, a condition
leading to multiple congenital anomalies and mental
retardation in patients. MEK1 also plays a role in cell
cycle control.

localized to the plasma membrane through
post-translational lipid modification or direct binding
to PIP2.

(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.

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)

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

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

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

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

Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK7
plays essential roles in the cell cycle and in
transcription. It associates with cyclin H and MAT1 and
acts as a CDK-Activating Kinase (CAK) by phosphorylating
and activating cell cycle CDKs (CDK1/2/4/6). In the
brain, it activates CDK5. CDK7 is also a component of
the general transcription factor TFIIH, which
phosphorylates the C-terminal domain (CTD) of RNA
polymerase II when it is bound with unphosphorylated
DNA, as present in the pre-initiation complex. Following
phosphorylation, the CTD dissociates from the DNA which
allows transcription initiation.

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,

Serine/Threonine Kinases (STKs), ROCK- and NDR-like
subfamily, fungal Sid2p- and Dbf2p-like proteins,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine

Dbf2p-like group is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. This group contains fungal kinases including
Schizosaccharomyces pombe Sid2p and Saccharomyces
cerevisiae Dbf2p. Group members show similarity to NDR
kinases in that they contain an N-terminal regulatory
(NTR) domain and an insert within the catalytic domain
that contains an auto-inhibitory sequence. Sid2p plays a
crucial role in the septum initiation network (SIN) and
in the initiation of cytokinesis. Dbf2p is important in
regulating the mitotic exit network (MEN) and in
cytokinesis.

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
serine/threonine residues on protein substrates. The
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.

threonine and tyrosine residues. The ERK cascade starts
with extracellular signals including growth factors,
hormones, and neurotransmitters, which act through
receptors and ion channels to initiate intracellular
signaling that leads to the activation at the MAPKKK
(Raf-1 or MOS) level, which leads to the transmission of
signals to MEK2, and finally to ERK1/2. The ERK cascade
plays an important role in cell proliferation,
differentiation, oncogenic transformation, and cell
cycle control, as well as in apoptosis and cell survival
under certain conditions. Gain-of-function mutations in
genes encoding ERK cascade proteins, including MEK2,
cause cardiofaciocutaneous (CFC) syndrome, a condition
leading to multiple congenital anomalies and mental
retardation in patients.

>gnl|CDD|133212 cd05081, PTKc_Jak2_Jak3_rpt2, Catalytic (repeat 2) domain of the
Protein Tyrosine Kinases, Janus kinases 2 and 3.
Protein Tyrosine Kinase (PTK) family; Janus kinase 2
(Jak2) and Jak3; catalytic (c) domain (repeat 2). The
PTKc family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Jak2 and
Jak3 are members of the Janus kinase (Jak) subfamily of
proteins, which are cytoplasmic (or nonreceptor) tyr
kinases containing an N-terminal FERM domain, followed
by a Src homology 2 (SH2) domain, a pseudokinase domain,
and a C-terminal catalytic tyr kinase domain. Jaks are
crucial for cytokine receptor signaling. They are
activated by autophosphorylation upon cytokine-induced
receptor aggregation, and subsequently trigger
downstream signaling events such as the phosphorylation
of signal transducers and activators of transcription
(STATs). Jak2 is widely expressed in many tissues while
Jak3 is expressed only in hematopoietic cells. Jak2 is
essential for the signaling of hormone-like cytokines
such as growth hormone, erythropoietin, thrombopoietin,
and prolactin, as well as some IFNs and cytokines that
signal through the IL-3 and gp130 receptors. Jak3 binds
the shared receptor subunit common gamma chain and thus,
is essential in the signaling of cytokines that use it
such as IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21.
Disruption of Jak2 in mice results in an embryonic
lethal phenotype with multiple defects including
erythropoietic and cardiac abnormalities. It is the only
Jak gene that results in a lethal phenotype when
disrupted in mice. A mutation in the pseudokinase domain
of Jak2, V617F, is present in many myeloproliferative
diseases, including almost all patients with
polycythemia vera, and 50% of patients with essential
thrombocytosis and myelofibrosis. Jak3 is important in
lymphoid development and myeloid cell differentiation.
Inactivating mutations in Jak3 have been reported in
humans with severe combined immunodeficiency (SCID).

Brk are a member of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases in general contain an N-terminal SH4 domain with
a myristoylation site, followed by SH3 and SH2 domains,
a tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr; they are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the
C-terminal tyr by Csk (C-terminal Src Kinase). Srm and
Brk however, lack the N-terminal myristylation sites.
Src proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Brk has been found to be overexpressed
in a majority of breast tumors.

subfamily is part of a larger superfamily that includes

that contains an auto-inhibitory sequence. Like many
other AGC kinases, NDR kinase requires phosphorylation
at two sites, the activation loop (A-loop) and the
hydrophobic motif (HM), for activity. Higher eukaryotes
contain two NDR isoforms, NDR1 and NDR2. Both isoforms
play a role in proper centrosome duplication. In
addition, NDR2 plays a role in regulating neuronal
growth and differentiation, as well as in facilitating
neurite outgrowth. It is also implicated in fear
conditioning as it contributes to the coupling of
neuronal morphological changes with fear-memory
consolidation. NDR2 is also referred to as STK38-like.

(MAPK) kinase kinase (MAPKKK or MKKK or MAP3K), that
phosphorylates and activates the MAPK kinase MEK5 (or
MKK5), which in turn phosphorylates and activates
extracellular signal-regulated kinase 5 (ERK5). The ERK5
cascade plays roles in promoting cell proliferation,
differentiation, neuronal survival, and neuroprotection.
MEKK3 plays an essential role in embryonic angiogenesis
and early heart development. In addition, MEKK3 is
involved in interleukin-1 receptor and Toll-like
receptor 4 signaling. It is also a specific regulator of
the proinflammatory cytokines IL-6 and GM-CSF in some
immune cells. MEKK3 also regulates calcineurin, which
plays a critical role in T cell activation, apoptosis,
skeletal myocyte differentiation, and cardiac
hypertrophy.

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

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,

transfer of the gamma-phosphoryl group from ATP to

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.

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

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.

other AGC kinases, NDR kinase requires phosphorylation
at two sites, the activation loop (A-loop) and the
hydrophobic motif (HM), for activity. Higher eukaryotes
contain two NDR isoforms, NDR1 and NDR2. Both isoforms
play a role in proper centrosome duplication. NDR1 is
highly expressed in thymus, muscle, lung and spleen. It
is not an essential protein because mice deficient of

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.

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.

which are cytoplasmic (or nonreceptor) tyr kinases
containing two Src homology 2 (SH2) domains N-terminal
to the catalytic tyr kinase domain. Syk was first cloned
from the spleen, and its function in hematopoietic cells
is well-established. Syk is involved in the signaling
downstream of activated receptors (including B-cell and
Fc receptors) that contain ITAMs (immunoreceptor tyr
activation motifs), leading to processes such as cell
proliferation, differentiation, survival, adhesion,
migration, and phagocytosis. More recently, Syk
expression has been detected in other cell types
(including epithelial cells, vascular endothelial cells,
neurons, hepatocytes, and melanocytes), suggesting a
variety of biological functions in non-immune cells. Syk
plays a critical role in maintaining vascular integrity
and in wound healing during embryogenesis. It also
regulates Vav3, which is important in osteoclast
function including bone development. In breast
epithelial cells, where Syk acts as a negative regulator
for epidermal growth factor receptor (EGFR) signaling,
loss of Syk expression is associated with abnormal
proliferation during cancer development suggesting a
potential role as a tumor suppressor. In mice, Syk has
been shown to inhibit malignant transformation of
mammary epithelial cells induced with murine mammary
tumor virus (MMTV).

glands, and the islets of Langerhans. Rodent homologs
were previously referred to as GTK (gastrointestinal tyr
kinase), BSK (beta-cell Src-like kinase), or IYK

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

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.

contain an N-terminal catalytic domain and a C-terminal
citron homology (CNH) regulatory domain. MAP4Ks (or
MAPKKKKs) are involved in MAPK signaling pathways that
are important in mediating cellular responses to
extracellular signals by activating a MAPK kinase kinase
(MAPKKK or MAP3K or MKKK). Each MAPK cascade is
activated either by a small GTP-binding protein or by an
adaptor protein, which transmits the signal either
directly to a MAP3K to start the triple kinase core
cascade or indirectly through a mediator kinase, a
MAP4K. MAP4K4 is also called Nck Interacting kinase
(NIK). It facilitates the activation of the MAPKs,
extracellular signal-regulated kinase (ERK) 1, ERK2, and
c-Jun N-terminal kinase (JNK), by phosphorylating and
activating MEKK1. MAP4K4 plays a role in tumor necrosis
factor (TNF) alpha-induced insulin resistance. MAP4K4
silencing in skeletal muscle cells from type II diabetic
patients restores insulin-mediated glucose uptake.
MAP4K4, through JNK, also plays a broad role in cell
motility, which impacts inflammation, homeostasis, as
well as the invasion and spread of cancer. MAP4K4 is
found to be highly expressed in most tumor cell lines
relative to normal tissue. MAP4K6 (also called MINK for
Misshapen/NIKs-related kinase) is activated after Ras
induction and mediates activation of p38 MAPK. MAP4K6
plays a role in cell cycle arrest, cytoskeleton
organization, cell adhesion, and cell motility.

(MEKK2) subfamily, catalytic (c) domain. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
MEKK2 subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside

3-kinase. MEKK2 is a mitogen-activated protein kinase
(MAPK) kinase kinase (MAPKKK or MKKK or MAP3K), that
phosphorylates and activates the MAPK kinase MEK5 (or
MKK5), which in turn phosphorylates and activates
extracellular signal-regulated kinase 5 (ERK5). The ERK5
cascade plays roles in promoting cell proliferation,
differentiation, neuronal survival, and neuroprotection.
MEKK2 also activates ERK1/2, c-Jun N-terminal kinase
(JNK) and p38 through their respective MAPKKs MEK1/2,
JNK-activating kinase 2 (JNKK2), and MKK3/6. MEKK2 plays
roles in T cell receptor signaling, immune synapse
formation, cytokine gene expression, as well as in EGF
and FGF receptor signaling.

It associates with the membrane though an N-terminal
PIP2 binding domain and also binds phospholipids via its
C-terminus. GRK5 deficiency is associated with early
Alzheimer's disease in humans and mouse models. GRK5
also plays a crucial role in the pathogenesis of
sporadic Parkinson's disease. It participates in the
regulation and desensitization of PDGFRbeta, a receptor
tyrosine kinase involved in a variety of downstream
cellular effects including cell growth, chemotaxis,
apoptosis, and angiogenesis. GRK5 also regulates
Toll-like receptor 4, which is involved in innate and

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.

Serine/threonine kinases (STKs), p21-activated kinase
(PAK) subfamily, Group I, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The PAK subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PAKs are Rho family GTPase-regulated kinases
that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs are
implicated in the regulation of many cellular processes
including growth factor receptor-mediated proliferation,
cell polarity, cell motility, cell death and survival,
and actin cytoskeleton organization. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
Group I PAKs, also called conventional PAKs, include
PAK1, PAK2, and PAK3. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). They interact
with the SH3 domain containing proteins Nck, Grb2 and
PIX. Binding of group I PAKs to activated GTPases leads
to conformational changes that destabilize the AID,
allowing autophosphorylation and full activation of the
kinase domain. Known group I PAK substrates include
MLCK, Bad, Raf, MEK1, LIMK, Merlin, Vimentin, Myc,
Stat5a, and Aurora A, among others.

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

(classical, atypical, and novel) depending on their mode
of activation and the structural characteristics of
their regulatory domain. nPKCs are calcium-independent,
but require DAG (1,2-diacylglycerol) and
phosphatidylserine (PS) for activity. There are four
nPKC isoforms, delta, epsilon, eta, and theta.
PKC-epsilon has been shown to behave as an oncoprotein.
Its overexpression contributes to neoplastic
transformation depending on the cell type. It
contributes to oncogenesis by inducing disordered cell
growth and inhibiting cell death. It also plays a role
in tumor invasion and metastasis. PKC-epsilon has also
been found to confer cardioprotection against ischemia
and reperfusion-mediated damage. Other cellular
functions include the regulation of gene expression,
cell adhesion, and cell motility.

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.

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.

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

Serine/Threonine Kinase, p21-activated kinase 1.
Serine/threonine kinases (STKs), p21-activated kinase
(PAK) 1, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The PAK
subfamily is part of a larger superfamily that includes
the catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PAKs are Rho family GTPase-regulated kinases
that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
PAK1 belongs to group I. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). PAK1 is
important in the regulation of many cellular processes
including cytoskeletal dynamics, cell motility, growth,
and proliferation. Although PAK1 has been regarded
mainly as a cytosolic protein, recent reports indicate
that PAK1 also exists in significant amounts in the
nucleus, where it is involved in transcription
modulation and in cell cycle regulatory events. PAK1 is
also involved in transformation and tumorigenesis. Its
overexpression, hyperactivation and increased nuclear
accumulation is correlated to breast cancer invasiveness
and progression. Nuclear accumulation is also linked to
tamoxifen resistance in breast cancer cells.

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

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). MKK5, also referred to as MEK5, is a
dual-specificity PK that phosphorylates its downstream
target, extracellular signal-regulated kinase 5 (ERK5),
on specific threonine and tyrosine residues. MKK5 is
activated by MEKK2 and MEKK3 in response to mitogenic
and stress stimuli. The ERK5 cascade promotes cell
proliferation, differentiation, neuronal survival, and
neuroprotection. This cascade plays an essential role in
heart development. Mice deficient in either ERK5 or MKK5
die around embryonic day 10 due to cardiovascular
defects including underdevelopment of the myocardium. In
addition, MKK5 is associated with metastasis and
unfavorable prognosis in prostate cancer.

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

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.

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.

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

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.

proteins are orphan receptor tyr kinases (RTKs)
containing an extracellular region with
immunoglobulin-like, cysteine-rich, and kringle domains,
a transmembrane segment, and an intracellular catalytic
domain. Ror RTKs are unrelated to the nuclear receptor
subfamily called retinoid-related orphan receptors
(RORs). RTKs are usually activated through ligand
binding, which causes dimerization and
autophosphorylation of the intracellular tyr kinase
catalytic domain. Ror kinases are expressed in many
tissues during development. Avian Ror1 was found to be
involved in late limb development. Studies in mice
reveal that Ror1 is important in the regulation of
neurite growth in central neurons, as well as in
respiratory development. Loss of Ror1 also enhances the
heart and skeletal abnormalities found in Ror2-deficient
mice.

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.

cytoplasmic (or nonreceptor) tyr kinases (nRTKs) with
similarity to Src kinases in that they contain Src
homology protein interaction domains (SH3, SH2)
N-terminal to the catalytic tyr kinase domain. Unlike
Src kinases, most Tec subfamily members (except Rlk)
also contain an N-terminal pleckstrin homology (PH)
domain, which binds the products of PI3K and allows
membrane recruitment and activation. In addition, some
members contain the Tec homology (TH) domain, which
contains proline-rich and zinc-binding regions. Tec
kinases form the second largest subfamily of nRTKs and
are expressed mainly by haematopoietic cells, although
Tec and Bmx are also found in endothelial cells. B-cells
express Btk and Tec, while T-cells express Itk, Txk, and
Tec. Collectively, Tec kinases are expressed in a
variety of myeloid cells such as mast cells, platelets,
macrophages, and dendritic cells. Each Tec kinase shows
a distinct cell-type pattern of expression. The function
of Tec kinases in lymphoid cells have been studied
extensively. They play important roles in the
development, differentiation, maturation, regulation,
survival, and function of B-cells and T-cells. Mutations
in Btk cause the severe B-cell immunodeficiency,
X-linked agammaglobulinaemia (XLA).

cellular responses to extracellular signals. They are
activated by the MAPK kinases MKK3 and MKK6, which in
turn are activated by upstream MAPK kinase kinases
including TAK1, ASK1, and MLK3, in response to cellular
stresses or inflammatory cytokines. Vertebrates contain
four isoforms of p38, named alpha, beta, gamma, and
delta. p38alpha, also called MAPK14, is expressed in
most tissues and is the major isoform involved in the
immune and inflammatory response. It is the central p38
MAPK involved in myogenesis. It plays a role in
regulating cell cycle check-point transition and
promoting cell differentiation. p38alpha also regulates
cell proliferation and death through crosstalk with the
JNK pathway. Its substrates include MAPK activated
protein kinase 2 (MK2), MK5, and the transcription
factors ATF2 and Mitf.

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

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

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.

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

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

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.

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

Serine/threonine kinases (STKs), p21-activated kinase
(PAK) subfamily, Group II, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from

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.
Group II PAKs, also called non-conventional PAKs,
include PAK4, PAK5, and PAK6. Group II PAKs contain PBD
(p21-binding domain) and catalytic domains, but lack
other motifs found in group I PAKs, such as an AID
(autoinhibitory domain) and SH3 binding sites. Since
group II PAKs do not contain an obvious AID, they may be
regulated differently from group I PAKs. While group I
PAKs interact with the SH3 containing proteins Nck, Grb2
and PIX, no such binding has been demonstrated for group
II PAKs. Some known substrates of group II PAKs are also
substrates of group I PAKs such as Raf, BAD, LIMK and
GEFH1. Unique group II substrates include MARK/Par-1 and
PDZ-RhoGEF. Group II PAKs play important roles in
filopodia formation, neuron extension, cytoskeletal
organization, and cell survival.

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

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

Tyrosine Kinase (PTK) family; Apoptosis-associated
tyrosine kinase (Aatyk) subfamily; catalytic (c) domain.
The Aatyk subfamily is also referred to as the lemur
tyrosine kinase (Lmtk) subfamily. It consists of Aatyk1
(Lmtk1), Aatyk2 (Lmtk2, Brek), Aatyk3 (Lmtk3), 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.
Aatyk proteins are mostly receptor tyr kinases (RTKs)
containing a transmembrane segment and a long C-terminal
cytoplasmic tail with a catalytic domain. Aatyk1 does
not contain a transmembrane segment and is a cytoplasmic
(or nonreceptor) kinase. Aatyk proteins are classified
as tyr kinases based on overall sequence similarity and
the phylogenetic tree. However, analysis of catalytic
residues suggests that Aatyk proteins may be
multispecific kinases, functioning also as
serine/threonine kinases. They are involved in neural
differentiation, nerve growth factor (NGF) signaling,
apoptosis, and spermatogenesis.

protein Kinase 1-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 1 (CDK1)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK1 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. 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.

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.

Protein Tyrosine Kinases, Janus kinases. Protein
Tyrosine Kinase (PTK) family; Janus kinase (Jak)
subfamily; pseudokinase domain (repeat1). The Jak
subfamily is composed of Jak1, Jak2, Jak3, TYK2, and
similar proteins. 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.
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 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.

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

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.

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

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,

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.

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

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

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
myeloproliferative syndrome (EMS), breast cancer, and
pancreatic adenocarcinoma.

protected against kainic acid-induced seizures, stroke,
sciatic axotomy neural death, and neuronal death due to
NGF deprivation, oxidative stress, or exposure to
beta-amyloid peptide. This suggests that JNK3 may play
roles in the pathogenesis of these diseases.

Serine/Threonine Kinase, p21-activated kinase 6.
Serine/threonine kinases (STKs), p21-activated kinase
(PAK) 6, 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.
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; Receptor tyrosine

(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.

protein serine/threonine kinases, RIO kinases, and

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

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

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.

protein kinase-like Protein Serine/Threonine Kinases.
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.

the MAPK kinases MKK4 and MKK7, which are in turn
activated by upstream MAPK kinase kinases as a result of
different stimuli including stresses such as ultraviolet
(UV) irradiation, hyperosmolarity, heat shock, or

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

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.

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

environmental and hormonal responses. AtMPK3 and AtMPK6
are also key regulators for stomatal development and
patterning. Group B is represented by AtMPK4, AtMPK13,

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

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. This subfamily is composed of CDK1 from higher
eukaryotes. 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. 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.

domain. The PTKc family is part of a larger superfamily
that includes the catalytic domains of other kinases
such as protein serine/threonine kinases, RIO kinases,
and phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. PDGFR
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).

a receptor tyr kinases (RTK) that is composed of two
alphabeta heterodimers. Binding of the ligand (IGF-1 or
IGF-2) to the extracellular alpha subunit activates the
intracellular tyr kinase domain of the transmembrane
beta subunit. Receptor activation leads to
autophosphorylation, which stimulates downstream kinase
activities and biological function. IGF-1R signaling is
important in the differentiation, growth, and survival
of normal cells. In cancer cells, where it is frequently
overexpressed, IGF-1R is implicated in proliferation,
the suppression of apoptosis, invasion, and metastasis.
IGF-1R is being developed as a therapeutic target in
cancer treatment.

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

VEGFR3 (or Flt4) is a member of the VEGFR subfamily of
proteins, which are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
seven immunoglobulin (Ig)-like domains, a transmembrane
segment, and an intracellular catalytic domain. 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. VEGFR3
preferentially binds the ligands VEGFC and VEGFD. VEGFR3
is essential for lymphatic endothelial cell (EC)
development and function. It has been shown to regulate
adaptive immunity during corneal transplantation. VEGFR3
is upregulated on blood vascular ECs in pathological
conditions such as vascular tumors and the periphery of
solid tumors. It plays a role in cancer progression and
lymph node metastasis. Missense mutations in the VEGFR3
gene are associated with primary human lymphedema.

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

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

(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.

part of a larger superfamily that includes the catalytic
domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. HER4 is a
member of the EGFR (HER, ErbB) subfamily of proteins,
which are receptor tyr kinases (RTKs) containing an
extracellular EGF-related ligand-binding region, a
transmembrane helix, and a cytoplasmic region with a tyr
kinase domain and a regulatory C-terminal tail. Unlike
other tyr kinases, phosphorylation of the activation
loop of EGFR proteins is not critical to their
activation. Instead, they are activated by
ligand-induced dimerization, leading to the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. Ligands that bind HER4 fall into two groups,
the neuregulins (or heregulins) and some EGFR (HER1)
ligands including betacellulin, HBEGF, and epiregulin.
All four neuregulins (NRG1-4) interact with HER4. Upon
ligand binding, HER4 forms homo- or heterodimers with
other HER proteins. HER4 is essential in embryonic
development. It is implicated in mammary gland, cardiac,
and neural development. As a postsynaptic receptor of
NRG1, HER4 plays an important role in synaptic
plasticity and maturation. The impairment of NRG1/HER4
signaling may contribute to schizophrenia.

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

and VEGFE. VEGFR2 signaling is implicated in all aspects
of normal and pathological vascular endothelial cell
biology. It induces a variety of cellular effects
including migration, survival, and proliferation. It is
critical in regulating embryonic vascular development
and angiogenesis. VEGFR2 is the major signal transducer
in pathological angiogenesis including cancer and

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.

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

development, proliferation, survival and motility.
Overexpression of HER2 results in its activation and
downstream signaling, even in the absence of ligand.
HER2 overexpression, mainly due to gene amplification,
has been shown in a variety of human cancers. Its role
in breast cancer is especially well-documented. HER2 is
up-regulated in about 25% of breast tumors and is
associated with increases in tumor aggressiveness,
recurrence and mortality. HER2 is a target for
monoclonal antibodies and small molecule inhibitors,
which are being developed as treatments for cancer. The
first humanized antibody approved for clinical use is
Trastuzumab (Herceptin), which is being used in
combination with other therapies to improve the survival
rates of patients with HER2-overexpressing breast
cancer.

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

Kinase, Insulin Receptor. Protein Tyrosine Kinase (PTK)
family; Insulin Receptor (InsR); 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. InsR is a
receptor tyr kinase (RTK) that is composed of two
alphabeta heterodimers. Binding of the insulin ligand to
the extracellular alpha subunit activates the
intracellular tyr kinase domain of the transmembrane
beta subunit. Receptor activation leads to
autophosphorylation, stimulating downstream kinase
activities, which initiate signaling cascades and
biological function. InsR signaling plays an important
role in many cellular processes including glucose
homeostasis, glycogen synthesis, lipid and protein
metabolism, ion and amino acid transport, cell cycle and
proliferation, cell differentiation, gene transcription,
and nitric oxide synthesis. Insulin resistance, caused
by abnormalities in InsR signaling, has been described
in diabetes, hypertension, cardiovascular disease,
metabolic syndrome, heart failure, and female
infertility.

suppressor of cytokine signaling (SOCS) proteins. SH2
domain found in SOCS proteins. SOCS was first recognized
as a group of cytokine-inducible SH2 (CIS) domain
proteins comprising eight family members in human (CIS
and SOCS1-SOCS7). In addition to the SH2 domain, SOCS
proteins have a variable N-terminal domain and a
conserved SOCS box in the C-terminal domain. SOCS
proteins bind to a substrate via their SH2 domain. The
prototypical members, CIS and SOCS1-SOCS3, have been
shown to regulate growth hormone signaling in vitro and
in a classic negative feedback response compete for
binding at phosphotyrosine sites in JAK kinase and
receptor pathways to displace effector proteins and
target bound receptors for proteasomal degradation. Loss
of SOCS activity results in excessive cytokine signaling
associated with a variety of hematopoietic, autoimmune,
and inflammatory diseases and certain cancers. Members
(SOCS4-SOCS7) were identified by their conserved SOCS
box, an adapter motif of 3 helices that associates
substrate binding domains, such as the SOCS SH2 domain,
ankryin, and WD40 with ubiquitin ligase components.
These show limited cytokine induction. In general SH2
domains are involved in signal transduction. They
typically bind pTyr-containing ligands via two surface
pockets, a pTyr and hydrophobic binding pocket, allowing
proteins with SH2 domains to localize to tyrosine
phosphorylated sites.

signal-regulated kinases 1 and 2 (ERK1/2) and Fus3
subfamily, catalytic (c) domain. STKs catalyze the

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

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.

Protein Tyrosine Kinase (PTK) family; Vascular
Endothelial Growth Factor Receptor (VEGFR) subfamily;
catalytic (c) domain. The VEGFR subfamily consists of
VEGFR1 (Flt1), VEGFR2 (Flk1), VEGFR3 (Flt4), and similar
proteins. The PTKc family is part of a larger

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.

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.

Kinase (PTK) family; Ephrin Receptor (EphR) subfamily;
most class EphA receptors including EphA3, EphA4, EphA5,
and EphA7, but excluding EphA1, EphA2 and EphA10;
catalytic (c) domain. The PTKc family is part of a
larger superfamily that includes the catalytic domains
of other kinases such as protein serine/threonine
kinases, RIO kinases, and phosphoinositide 3-kinase
(PI3K). PTKs catalyze the transfer of the
gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. EphRs comprise the
largest subfamily of receptor tyr kinases (RTKs). In
general, class EphA receptors bind GPI-anchored ephrin-A
ligands. There are ten vertebrate EphA receptors
(EphA1-10), which display promiscuous interactions with
six ephrin-A ligands. One exception is EphA4, which also
binds ephrins-B2/B3. EphRs contain an ephrin-binding
domain and two fibronectin repeats extracellularly, a
transmembrane segment, and a cytoplasmic tyr kinase
domain. Binding of the ephrin ligand to EphR requires
cell-cell contact since both are anchored to the plasma
membrane. The resulting downstream signals occur
bidirectionally in both EphR-expressing cells (forward
signaling) and ephrin-expressing cells (reverse
signaling). Ephrin/EphR interaction mainly results in
cell-cell repulsion or adhesion, making it important in
neural development and plasticity, cell morphogenesis,
cell-fate determination, embryonic development, tissue
patterning, and angiogenesis. EphARs and ephrin-A
ligands are expressed in multiple areas of the
developing brain, especially in the retina and tectum.
They are part of a system controlling retinotectal
mapping.

Kinase, Receptor tyrosine kinase-like Orphan Receptor 2.
Protein Tyrosine Kinase (PTK) family; Receptor tyrosine
kinase-like Orphan Receptor 2 (Ror2); catalytic (c)
domain. The PTKc family is part of a larger superfamily
that includes the catalytic domains of other kinases
such as protein serine/threonine kinases, RIO kinases,
and phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Ror
proteins are orphan receptor tyr kinases (RTKs)
containing an extracellular region with
immunoglobulin-like, cysteine-rich, and kringle domains,
a transmembrane segment, and an intracellular catalytic
domain. Ror RTKs are unrelated to the nuclear receptor
subfamily called retinoid-related orphan receptors
(RORs). RTKs are usually activated through ligand
binding, which causes dimerization and
autophosphorylation of the intracellular tyr kinase
catalytic domain. Ror2 plays important roles in skeletal
and heart formation. Ror2-deficient mice show widespread
bone abnormalities, ventricular defects in the heart,
and respiratory dysfunction. Mutations in human Ror2
result in two different bone development genetic
disorders, recessive Robinow syndrome and brachydactyly
type B. Ror2 is also implicated in neural development.

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

domain of yeast vacuolar transport chaperone (VTC)
protein VTC4, and similar proteins. Saccharomyces
cerevisiae VTC-1, -2, -3, and -4 comprise the
membrane-integral VTC complex. VTC-2,-3, and -4 contain
polyP polymerase domains. S. cerevisiae VTC4 belongs to
this subgroup. For VTC4 it has been shown that this
domain generates polyP from ATP by a phosphotransfer
reaction releasing ADP. This activity is metal
ion-dependent. The ATP gamma phosphate may be cleaved
and then transferred to an acceptor phosphate to form
polyP. PolyP is ubiquitous. In prokaryotes, it is a
store of phosphate and energy. In eukaryotes, polyPs
have roles in bone calcification, and osmoregulation,
and in phosphate transport in the symbiosis of
mycorrhizal fungi and plants. This subgroup belongs to
the CYTH/triphosphate tunnel metalloenzyme (TTM)-like
superfamily, whose enzymes have a unique active site
located within an eight-stranded beta barrel.

This is a family of proteins that are activated by PhoP.
PhoP protein controls the expression of a large number
of genes that mediate adaptation to low Mg2+
environments and/or virulence in several bacterial
species. YbrL is proposed to be acting in a loop
activity with PhoP and PrmA analogous to the
multicomponent loop in Salmonella where the
PhoP-dependent PmrD protein activates the regulatory
protein PmrA, and the activated PmrA then represses
transcription from the PmrD promoter which harbours
binding sites for both the PhoP and PmrA proteins.
Expression of YrbL is induced in low Mg2+ in a
PhoP-dependent fashion and repressed by Fe3+ in a
PmrA-dependent manner.
