>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.

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

>gnl|CDD|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.

c-Jun N-terminal Kinase. Serine/Threonine Kinases
(STKs), c-Jun N-terminal kinase (JNK) subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The JNK subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. JNKs are
mitogen-activated protein kinases (MAPKs) that are
involved in many stress-activated responses including
those during inflammation, neurodegeneration, apoptosis,
and persistent pain sensitization, among others. They
are also essential regulators of physiological and
pathological processes and are involved in the
pathogenesis of several diseases such as diabetes,
atherosclerosis, stroke, Parkinson's and Alzheimer's.
Vetebrates harbor three different JNK genes (Jnk1, Jnk2,
and Jnk3) that are alternatively spliced to produce at
least 10 isoforms. JNKs are specifically activated by
the MAPK kinases MKK4 and MKK7, which are in turn
activated by upstream MAPK kinase kinases as a result of
different stimuli including stresses such as ultraviolet
(UV) irradiation, hyperosmolarity, heat shock, or
cytokines. JNKs activate a large number of different
substrates based on specific stimulus, cell type, and
cellular condition, and may be implicated in seemingly
contradictory functions.

substrates. The p38 subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. p38 kinases are
mitogen-activated protein kinases (MAPKs), serving as
important mediators of cellular responses to
extracellular signals. They function in the regulation
of the cell cycle, cell development, cell
differentiation, senescence, tumorigenesis, apoptosis,
pain development and pain progression, and immune
responses. p38 kinases are activated by the MAPK kinases
MKK3 and MKK6, which in turn are activated by upstream
MAPK kinase kinases including TAK1, ASK1, and MLK3, in
response to cellular stresses or inflammatory cytokines.
p38 substrates include other protein kinases and factors
that regulate transcription, nuclear export, mRNA
stability and translation. p38 kinases are drug targets
for the inflammatory diseases psoriasis, rheumatoid
arthritis, and chronic pulmonary disease. Vertebrates
contain four isoforms of p38, named alpha, beta, gamma,
and delta, which show varying substrate specificity and
expression patterns. p38alpha and p38beta are
ubiquitously expressed, p38gamma is predominantly found
in skeletal muscle, and p38delta is found in the heart,
lung, testis, pancreas, and small intestine.

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.

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.

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

pathogenesis of these diseases.

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.

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

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.

They regulate cell growth, cell proliferation, and cell

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

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. p38beta, also called MAPK11, is widely expressed
in tissues and shows more similarity with p38alpha than
with the other isoforms. Both are sensitive to
pyridinylimidazoles and share some common substrates
such as MAPK activated protein kinase 2 (MK2) and the
transcription factors ATF2, c-Fos and, ELK-1. p38beta is
involved in regulating the activation of the
cyclooxygenase-2 promoter and the expression of
TGFbeta-induced alpha-smooth muscle cell actin.

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

Serine/threonine kinases (STKs), thousand-and-one amino
acids 2 (TAO2) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The TAO subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,

3-kinase. TAO proteins possess mitogen-activated protein
kinase (MAPK) kinase kinase (MAPKKK or MAP3K or MKKK)
activity. MAPK signaling cascades are important in
mediating cellular responses to extracellular signals.
Human TAO2 is also known as prostate-derived Ste20-like
kinase (PSK) and was identified in a screen for
overexpressed RNAs in prostate cancer. TAO2 activates
both p38 and c-Jun N-terminal kinase (JNK), by
phosphorylating and activating the respective MAP/ERK
kinases (MEKs, also known as MKKs or MAPKKs), MEK3/MEK6
and MKK4/MKK7. TAO2 contains a long C-terminal extension
with autoinhibitory segments. It is activated by the
release of this inhibition and the phosphorylation of
its activation loop serine. TAO2 functions as a
regulator of actin cytoskeletal and microtubule
organization. In addition, it regulates the transforming
growth factor-activated kinase 1 (TAK1), which is a
MAPKKK that plays an essential role in the signaling
pathways of tumor necrosis factor (TNF), interleukin 1
(IL-1), and Toll-like receptor (TLR).

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

The MAPKK, LmxPK4, from Leishmania mexicana, is
important in differentiation and virulence.
Dictyostelium discoideum MEK1 is required for proper

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

similar to mitogen-activated protein kinase (MAPK),
kinase kinase kinase 4 (MAP4K4), and MAP4K6. MAP4Ks
participate in some MAPK signaling pathways by
activating a MAPK kinase kinase (MAPKKK or MAP3K or
MKKK). TNIK is an effector of Rap2, a small GTP-binding
protein from the Ras family. TNIK specifically activates
the c-Jun N-terminal kinase (JNK) pathway and plays a
role in regulating the actin cytoskeleton.

protein Kinase 9-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 9 (CDK9)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK9-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. CDKs belong to a large family of STKs that are
regulated by their cognate cyclins. Together, they are
involved in the control of cell-cycle progression,
transcription, and neuronal function. This subfamily is
composed of CDK9 and CDK12 from higher eukaryotes, yeast
BUR1, C-type plant CDKs (CdkC), and similar proteins.
CDK9, BUR1, and CdkC are functionally equivalent. They
act as a kinase for the C-terminal domain of RNA
polymerase II and participate in regulating mutliple
steps of gene expression including transcription
elongation and RNA processing. CDK9 and CdkC associate
with T-type cyclins while BUR1 associates with the
cyclin BUR2. CDK12 is a unique CDK that contains an
arginine/serine-rich (RS) domain, which is predominantly
found in splicing factors. CDK12 interacts with cyclins
L1 and L2, and participates in regulating transcription
and alternative splicing.

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.

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. 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.

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

catalyze the transfer of the gamma-phosphoryl group from

The MAP4K4/MAP4K6 subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. Members of this subfamily
contain an N-terminal catalytic domain and a C-terminal
citron homology (CNH) regulatory domain. MAP4Ks (or
MAPKKKKs) are involved in MAPK signaling pathways that
are important in mediating cellular responses to
extracellular signals by activating a MAPK kinase kinase
(MAPKKK or MAP3K or MKKK). Each MAPK cascade is
activated either by a small GTP-binding protein or by an
adaptor protein, which transmits the signal either
directly to a MAP3K to start the triple kinase core
cascade or indirectly through a mediator kinase, a
MAP4K. MAP4K4 is also called Nck Interacting kinase
(NIK). It facilitates the activation of the MAPKs,
extracellular signal-regulated kinase (ERK) 1, ERK2, and
c-Jun N-terminal kinase (JNK), by phosphorylating and
activating MEKK1. MAP4K4 plays a role in tumor necrosis
factor (TNF) alpha-induced insulin resistance. MAP4K4
silencing in skeletal muscle cells from type II diabetic
patients restores insulin-mediated glucose uptake.
MAP4K4, through JNK, also plays a broad role in cell
motility, which impacts inflammation, homeostasis, as
well as the invasion and spread of cancer. MAP4K4 is
found to be highly expressed in most tumor cell lines
relative to normal tissue. MAP4K6 (also called MINK for
Misshapen/NIKs-related kinase) is activated after Ras
induction and mediates activation of p38 MAPK. MAP4K6
plays a role in cell cycle arrest, cytoskeleton
organization, cell adhesion, and cell motility.

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

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.

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.

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

STKs catalyze the transfer of the gamma-phosphoryl group

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

regulate G protein-coupled receptors (GPCRs), the
largest superfamily of cell surface receptors, which
regulate some part of nearly all physiological
functions. Phosphorylated GPCRs bind to arrestins, which
prevents further G protein signaling despite the
presence of activating ligand. GRKs contain a central
catalytic domain, flanked by N- and C-terminal
extensions. The N-terminus contains an RGS (regulator of
G protein signaling) homology (RH) domain and several
motifs. The C-terminus diverges among different groups
of GRKs. There are seven types of GRKs, named GRK1 to
GRK7. They are subdivided into three main groups: visual
(GRK1/7); beta-adrenergic receptor kinases (GRK2/3); and
GRK4-like (GRK4/5/6). Expression of GRK2/3/5/6 is
widespread while GRK1/4/7 show a limited tissue
distribution. The substrate spectrum of the widely
expressed GRKs partially overlaps. GRKs play important
roles in the cardiovascular, immune, respiratory,
skeletal, and nervous systems.

The PAK subfamily is part of a larger superfamily that

that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
Group II PAKs, also called non-conventional PAKs,
include PAK4, PAK5, and PAK6. Group II PAKs contain PBD
(p21-binding domain) and catalytic domains, but lack
other motifs found in group I PAKs, such as an AID
(autoinhibitory domain) and SH3 binding sites. Since
group II PAKs do not contain an obvious AID, they may be
regulated differently from group I PAKs. While group I
PAKs interact with the SH3 containing proteins Nck, Grb2
and PIX, no such binding has been demonstrated for group
II PAKs. Some known substrates of group II PAKs are also
substrates of group I PAKs such as Raf, BAD, LIMK and
GEFH1. Unique group II substrates include MARK/Par-1 and
PDZ-RhoGEF. Group II PAKs play important roles in
filopodia formation, neuron extension, cytoskeletal
organization, and cell survival.

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.

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 MST1, MST2, and
related proteins including Drosophila Hippo and
Dictyostelium discoideum Krs1 (kinase responsive to
stress 1). MST1/2 and Hippo are involved in a conserved
pathway that governs cell contact inhibition, organ size
control, and tumor development. MST1 activates the
mitogen-activated protein kinases (MAPKs) p38 and c-Jun
N-terminal kinase (JNK) through MKK7 (a MAPK kinase) and
MEKK1 (a MAPK kinase kinase) by acting as a MAPK kinase
kinase kinase (MAPKKKK). Activation of JNK by MST1 leads
to caspase activation and apoptosis. MST1 has also been
implicated in cell proliferation and differentiation.
Krs1 may regulate cell growth arrest and apoptosis in
response to cellular stress.

as an important factor in endocrine therapy resistance
in breast cancer. CDK10 silencing increases the
transcription of c-RAF and the activation of the p42/p44
MAPK pathway, which leads to antiestrogen resistance.
Patients who express low levels of CDK10 relapse early

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

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

signaling pathways that are important in mediating
cellular responses to extracellular signals by
activating a MAPK kinase kinase (MAPKKK or MAP3K or
MKKK). Each MAPK cascade is activated either by a small
GTP-binding protein or by an adaptor protein, which
transmits the signal either directly to a MAP3K to start
the triple kinase core cascade or indirectly through a
mediator kinase, a MAP4K. MAP4K3 plays a role in the
nutrient-responsive pathway of mTOR (mammalian target of
rapamycin) signaling. MAP4K3 is required in the
activation of S6 kinase by amino acids and for the
phosphorylation of the mTOR-regulated inhibitor of
eukaryotic initiation factor 4E. mTOR regulates ribosome
biogenesis and protein translation, and is frequently
deregulated in cancer.

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

kinases (PKs), aminoglycoside phosphotransferase,

RIO kinases are atypical protein serine kinases present

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

Serine/Threonine Kinases (STKs), Phototropin-like
subfamily, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
phototropin-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. Included in this subfamily
are plant phototropins and predominantly uncharacterized
fungal STKs whose catalytic domains resemble the
phototropin kinase domain. One protein from Neurospora
crassa is called nrc-2. Phototropins are blue-light
receptors that control responses such as phototropism,
stromatal opening, and chloroplast movement in order to
optimize the photosynthetic efficiency of plants. They
are light-activated STKs that contain an N-terminal
photosensory domain and a C-terminal catalytic domain.
The N-terminal domain contains two LOV (Light, Oxygen or
Voltage) domains that binds FMN. Photoexcitation of the
LOV domains results in autophosphorylation at multiple
sites and activation of the catalytic domain. Neurospora
crassa nrc-2 plays a role in growth and development by
controlling entry into the conidiation program.

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.

MKKK). Each MAPK cascade is activated either by a small
GTP-binding protein or by an adaptor protein, which
transmits the signal either directly to a MAP3K to start
the triple kinase core cascade or indirectly through a
mediator kinase, a MAP4K. MAP4K5, also called germinal

activate the MAPK c-Jun N-terminal kinase (JNK). MAP4K5
also facilitates Wnt signaling in B cells, and may
therefore be implicated in the control of cell fate,

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

neuronal morphological changes with fear-memory
consolidation. NDR2 is also referred to as STK38-like.

(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.

Serine/threonine kinases (STKs), Apoptosis
signal-regulating kinase (ASK) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The ASK subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. Subfamily members
are mitogen-activated protein kinase (MAPK) kinase
kinases (MAPKKKs or MKKKs or MAP3Ks) and include ASK1,
ASK2, and MAPKKK15. MAPKKKs phosphorylate and activate
MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn
phosphorylate and activate MAPKs during signaling
cascades that are important in mediating cellular
responses to extracellular signals. ASK1 (also called
MAPKKK5) functions in the c-Jun N-terminal kinase (JNK)
and p38 MAPK signaling pathways by directly activating
their respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. It
plays important roles in cytokine and stress responses,
as well as in reactive oxygen species (ROS)-mediated
cellular responses. ASK1 is implicated in various
diseases mediated by oxidative stress including
inschemic heart disease, hypertension, vessel injury,
brain ischemia, Fanconi anemia, asthma, and pulmonary
edema, among others. ASK2 (also called MAPKKK6)
functions only in a heteromeric complex with ASK1, and
can activate ASK1 by direct phosphorylation. The
function of MAPKKK15 is still unknown.

It is widely expressed in many tissues. It is abundant
in the brain and is also found in keratinocytes, colonic
mucosa epithelium, lung epithelium, thyroid follicles,
and the islets of Langerhans. During embryonic
development, it is found in the developing
neuroectoderm. DDR1 is a key regulator of cell
morphogenesis, differentiation and proliferation. It is
important in the development of the mammary gland, the
vasculator and the kidney. DDR1 is also found in human
leukocytes, where it facilitates cell adhesion,
migration, maturation, and cytokine production.

transmembrane helix, and a cytoplasmic region with a tyr

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

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.

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

protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. LATS was originally identified in Drosophila
using a screen for genes whose inactivation led to
overproliferation of cells. In tetrapods, there are two
LATS isoforms, LATS1 and LATS2. Inactivation of LATS1 in
mice results in the development of various tumors,
including sarcomas and ovarian cancer. LATS functions as
a tumor suppressor and is implicated in cell cycle
regulation.

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

myosins may play an important role in maintaining the
structural integrity of photoreceptor cell microvilli.
In photoreceptor cells, they may also function as cargo
carriers during light-dependent translocation of
proteins such as transducin and arrestin. Class IIIA
myosin is highly expressed in retina and in inner ear
hair cells. It is localized to the distal ends of
actin-bundled structures. Mutations in human myosin IIIA
are responsible for progressive nonsyndromic hearing
loss. Human myosin IIIA possesses ATPase and kinase
activities, and the ability to move actin filaments in a
motility assay. It may function as a cellular

from the CAMK family, similar to 90 kDa ribosomal
protein S6 kinases (RSKs). MSKs are activated by two
major signaling cascades, the Ras-MAPK and p38 stress
kinase pathways, which trigger phosphorylation in the
activation loop (A-loop) of the CTD of MSK. The active
CTD phosphorylates the hydrophobic motif (HM) of NTD,
which facilitates the phosphorylation of the A-loop and
activates the NTD, which in turn phosphorylates
downstream targets. MSK1 plays a role in the regulation
of translational control and transcriptional activation.
It phosphorylates the transcription factors, CREB and
NFkappaB. It also phosphorylates the nucleosomal
proteins H3 and HMG-14. Increased phosphorylation of
MEK1 is associated with the development of cerebral
ischemic/hypoxic preconditioning.

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.

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

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

Receptor (EGFR) subfamily; catalytic (c) domain. EGFR
(HER, ErbB) subfamily members include EGFR (HER1,

similar proteins. The PTKc family is part of a larger

catalyze the transfer of the gamma-phosphoryl group from

The EGFR proteins are receptor tyr kinases (RTKs)
containing an extracellular EGF-related ligand-binding
region, a transmembrane helix, and a cytoplasmic region
with a tyr kinase domain and a regulatory C-terminal
tail. Unlike other tyr kinases, phosphorylation of the
activation loop of EGFR proteins is not critical to
their activation. Instead, they are activated by
ligand-induced dimerization, resulting in the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. Collectively, they can recognize a variety of
ligands including EGF, TGFalpha, and neuregulins, among
others. All four subfamily members can form homo- or
heterodimers. HER3 contains an impaired kinase domain
and depends on its heterodimerization partner for
activation. EGFR subfamily members are involved in
signaling pathways leading to a broad range of cellular
responses including cell proliferation, differentiation,
migration, growth inhibition, and apoptosis. Gain of
function alterations, through their overexpression,
deletions, or point mutations in their kinase domains,
have been implicated in various cancers. These receptors
are targets of many small molecule inhibitors and
monoclonal antibodies used in cancer therapy.

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.

(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.

Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. GRK3 (also known as beta-adrenergic
receptor kinase 2) is widely expressed in many tissues.
GRK3-deficient mice show a lack of olfactory receptor
desensitization and altered regulation of the M2
muscarinic airway. GRK3 is involved in modulating the
cholinergic response of airway smooth muscles. It also
plays a role in dopamine receptor regulation. GRK3
promoter polymorphisms may be associated with bipolar
disorder.

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.

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

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).

catalyze the transfer of the gamma-phosphoryl group from

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,
