>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|173737 cd07834, STKc_MAPK, Catalytic domain of the Serine/Threonine
Kinase, Mitogen-Activated Protein Kinase.
Serine/Threonine Kinases (STKs), Mitogen-Activated
Protein Kinase (MAPK) subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The MAPK 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 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. 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.

>gnl|CDD|173739 cd07838, STKc_CDK4_6_like, Catalytic domain of Cyclin-Dependent
protein Kinase 4 and 6-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Cyclin-dependent
protein kinase 4 (CDK4) and CDK6-like subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK4/6-like
subfamily is part of a larger superfamily that includes
the catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. CDKs belong to a large family of STKs that are
regulated by their cognate cyclins. Together, they are
involved in the control of cell-cycle progression,
transcription, and neuronal function. CDK4 and CDK6
partner with D-type cyclins to regulate the early G1
phase of the cell cycle. They are the first kinase
activated by mitogenic signals to release cells from the
G0 arrested state. CDK4 and CDK6 are both expressed
ubiquitously, associate with all three D cyclins (D1, D2
and D3), and phosphorylate the retinoblastoma (pRb)
protein. They are also regulated by the INK4 family of
inhibitors which associate with either the CDK alone or
the CDK/cyclin complex. CDK4 and CDK6 show differences
in subcellular localization, sensitivity to some
inhibitors, timing in activation, tumor selectivity, and
possibly substrate profiles. Although CDK4 and CDK6 seem
to show some redundancy, they also have discrete,
nonoverlapping functions. CDK6 plays an important role
in cell differentiation.

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

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.

STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
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.

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.

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.

is part of a larger superfamily that includes the

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.

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

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.

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.

composed of CDKL1-5 and similar proteins. Some CDKLs,
like CDKL1 and CDKL3, may be implicated in
transformation and others, like CDKL3 and CDKL5, are
associated with mental retardation when impaired. CDKL2
plays a role in learning and memory.

partners with all three D-type cyclins (D1, D2, and D3)
and is also regulated by INK4 inhibitors. It is active
towards the retinoblastoma (pRb) protein and plays a
role in regulating the early G1 phase of the cell cycle.
It is expressed ubiquitously and is localized in the
nucleus. CDK4 also shows kinase activity towards Smad3,
a signal transducer of transforming growth factor
(TGF)-beta signaling which modulates transcription and
plays a role in cell proliferation and apoptosis. CDK4
is inhibited by the p21 inhibitor and is specifically
mutated in human melanoma.

signaling of some nuclear receptor transcription
factors. ERK7 regulates hormone-dependent degradation of
estrogen receptor alpha while ERK8 down-regulates the
transcriptional co-activation androgen and
glucocorticoid receptors.

cell division and environmental stress response. AtMPK4
also participates in regulating innate immunity. Group C
is represented by AtMPK1, AtMPK2, NtNTF3, Oryza sativa

in stress responses. AtMPK1 and AtMPK2 are activated
following mechanical injury and in the presence of

(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 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.

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

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),

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.

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.

suppressor and is implicated in cell cycle regulation.
Inactivation of LATS1 in mice results in the development
of various tumors, including sarcomas and ovarian
cancer. Promoter methylation, loss of heterozygosity,
and missense mutations targeting the LATS1 gene have
also been found in human sarcomas and ovarian cancers.
In addition, decreased expression of LATS1 is associated
with an aggressive phenotype and poor prognosis. LATS1

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.

kinases (MAPKs) are important mediators of cellular
responses to extracellular signals. NLK is an atypical
MAPK that is not regulated by a MAPK kinase. It
functions downstream of the MAPK kinase kinase Tak1,
which also plays a role in activating the JNK and p38
MAPKs. The Tak1/NLK pathways are regulated by Wnts, a
family of secreted proteins that is critical in the
control of asymmetric division and cell polarity. NLK
can phosphorylate transcription factors from the TCF/LEF
family, inhibiting their ability to activate the
transcription of target genes. In prostate cancer cells,
NLK is involved in regulating androgen receptor-mediated
transcription and its expression is altered during
cancer progression.

family GTPase-regulated kinases that serve as important

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

protein 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.

Upon activation by cyclin E, it phosphorylates the

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.

Serine/threonine kinases (STKs), p21-activated kinase
(PAK) 3, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to

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

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

(MEKK3)-like subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from

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.

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

of other protein serine/threonine kinases, protein
tyrosine kinases, RIO kinases, aminoglycoside

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

PRKX gene is located in the Xp22.3 subregion and has a
homolog called PRKY on the Y chromosome. An abnormal
interchange between PRKX aand PRKY leads to the sex
reversal disorder of XX males and XY females. PRKX is
implicated in granulocyte/macrophage lineage
differentiation, renal cell epithelial migration, and
tubular morphogenesis in the developing kidney.

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.

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

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.

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

of S6 kinase by amino acids and for the phosphorylation
of the mTOR-regulated inhibitor of eukaryotic initiation

phosphorylate their downstream targets, MAPKs, at
specific threonine and tyrosine residues. There are
three MAPK subfamilies: extracellular signal-regulated
kinase (ERK), c-Jun N-terminal kinase (JNK), and p38. In
mammalian cells, there are seven MAPKKs (named MKK1-7)
and 20 MAPKKKs. Each MAPK subfamily can be activated by
at least two cognate MAPKKs and by multiple MAPKKKs.

Serine/threonine kinases (STKs), 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.

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

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.

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

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.

activity. MAPK signaling cascades are important in
mediating cellular responses to extracellular signals.
Human TAO2 is also known as prostate-derived Ste20-like

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

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

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

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

phosphatidylserine (PS) for activation. cPKCs contain a
calcium-binding C2 region in their regulatory domain.
There are four cPKC isoforms, named alpha, betaI,
betaII, and gamma. cPKCs are potent kinases for
histones, myelin basic protein, and protamine. PKC-gamma
is mainly expressed in neuronal tissues. It plays a role
in protection from ischemia.

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

(MAP) kinase signaling pathways are important mediators
of cellular responses to extracellular signals. The
pathways involve a triple kinase core cascade comprising
of the MAP kinase (MAPK), which is phosphorylated and
activated by a MAPK kinase (MAPKK or MKK), which itself
is phosphorylated and activated by a MAPK kinase kinase
(MAPKKK or MKKK). Members of this group include MAPKKs
from plants, kinetoplastids, alveolates, and mycetozoa.
The MAPKK, LmxPK4, from Leishmania mexicana, is
important in differentiation and virulence.
Dictyostelium discoideum MEK1 is required for proper
chemotaxis. MEK1 null mutants display severe defects in
cell polarization and directional movement. Plants
contain multiple MAPKKs like other eukaryotes. The
Arabidopsis genome encodes for 10 MAPKKs while poplar
and rice contain 13 MAPKKs each. The functions of these
proteins have not been fully elucidated. There is
evidence to suggest that MAPK cascades are involved in
plant stress responses. In Arabidopsis, MKK3 plays a
role in pathogen signaling, MKK2 is involved in cold and
salt stress signaling, MKK4/MKK5 participates in innate
immunity, and MKK7 regulates basal and systemic acquired
resistance.

(Txk), and similar proteins. The PTKc family is part of
a larger superfamily that includes the catalytic domains
of other kinases such as protein serine/threonine

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

GRK1 to GRK7. GRK6 is widely expressed in many tissues.
t is expressed as multiple splice variants with
different domain architectures. It is
post-translationally palmitoylated and localized in the

of dopamine, M3 muscarinic, opioid, and chemokine

exhibit altered dopamine receptor regulation, decreased
lymphocyte chemotaxis, and increased acute inflammation
and neutrophil chemotaxis.

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

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

previously referred to as CDK11. However, this is a
confusing nomenclature as CDC2L6 is distinct from
CDC2L1, which is represented by the two protein products
from its gene, called CDK11(p110) and CDK11(p58), as
well as the caspase-processed CDK11(p46). CDK11(p110),
CDK11(p58), and CDK11(p46)do not belong to this

a multiprotein complex that provides a platform to
connect transcriptional and chromatin regulators and
cofactors, in order to activate and mediate RNA
polymerase II transcription. CDC2L6 is localized mainly
in the nucleus amd exerts an opposing effect to CDK8 in

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

Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 8 (CDK8) subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The CDK8 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. CDK8
can act as a negative or positive regulator of
transcription, depending on the scenario. Together with
its regulator, cyclin C, it reversibly associates with
the multi-subunit core Mediator complex, a cofactor that
is involved in regulating RNA polymerase II (RNAP
II)-dependent transcription. CDK8 phosphorylates cyclin
H, a subunit of the general transcription factor TFIIH,
which results in the inhibition of TFIIH-dependent
phosphorylation of the C-terminal domain (CTD) of RNAP
II, facilitating the inhibition of transcription. It has
also been shown to promote transcription by a mechanism
that is likely to involve RNAP II phosphorylation. CDK8
also functions as a stimulus-specific positive
coregulator of p53 transcriptional responses.

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.

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.

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.

receptors that control responses such as phototropism,
stromatal opening, and chloroplast movement in order to
optimize the photosynthetic efficiency of plants. They

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,

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

fusion protein FIP1L1-PDGFR alpha, derived from
interstitial deletion, is associated with idiopathic
hypereosinophilic syndrome (HES) and chronic
eosinophilic leukemia (CEL).

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.

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

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

PTKc family is part of a larger superfamily that
includes the catalytic domains of other kinases such as

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.

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

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

many varied interactions of Jak1 and its ubiquitous
expression suggest many biological roles. Jak1 is
important in neurological development, as well as in
lymphoid development and function. It also plays a role
in the pathophysiology of cardiac hypertrophy and heart
failure. A mutation in the ATP-binding site of Jak1 was
identified in a human uterine leiomyosarcoma cell line,
resulting in defective cytokine induction and antigen

homodimerization. PDGFR signaling plays many roles in
normal embryonic development and adult physiology. PDGFR
beta signaling leads to a variety of cellular effects

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

diiron oxygen transport protein found in four marine
invertebrate phyla including priapulida, brachiopoda,
sipunculida, and annelida, as well as in protozoa.
Myohemerythrin (Mhr), a hemerythrin homolog, is found in
the muscle tissue of sipunculids as well as in
polycheate and oligocheate annelids. In addition to
oxygen transport, Mhr proteins are involved in cadmium
fixation and host anti-bacterial defense. Hr and Mhr
proteins have the same "four alpha helix bundle" motif
and active site structure. Hr forms oligomers, the
octameric form being most prevalent, while Mhr is
monomeric.

Kinase, Ephrin Receptor A2. Protein Tyrosine Kinase
(PTK) family; Ephrin Receptor (EphR) subfamily; EphA2
receptor; catalytic (c) domain. The PTKc family is part
of a larger superfamily that includes the catalytic
domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. EphRs
comprise the largest subfamily of receptor tyr kinases
(RTKs). In general, class EphA receptors bind
GPI-anchored ephrin-A ligands. There are ten vertebrate
EphA receptors (EphA1-10), which display promiscuous
interactions with six ephrin-A ligands. EphRs contain an
ephrin binding domain and two fibronectin repeats
extracellularly, a transmembrane segment, and a
cytoplasmic tyr kinase domain. Binding of the ephrin
ligand to EphR requires cell-cell contact since both are
anchored to the plasma membrane. The resulting
downstream signals occur bidirectionally in both
EphR-expressing cells (forward signaling) and
ephrin-expressing cells (reverse signaling). Ephrin/EphR
interaction mainly results in cell-cell repulsion or
adhesion, making it important in neural development and
plasticity, cell morphogenesis, cell-fate determination,
embryonic development, tissue patterning, and
angiogenesis. The EphA2 receptor is overexpressed in
tumor cells and tumor blood vessels in a variety of
cancers including breast, prostate, lung, and colon. As
a result, it is an attractive target for drug design
since its inhibition could affect several aspects of
tumor progression.

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. 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.

family is part of a larger superfamily that includes the
catalytic domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and

part of the FGFR subfamily, which are receptor tyr
kinases (RTKs) containing an extracellular
ligand-binding region with three immunoglobulin-like
domains, a transmembrane segment, and an intracellular
catalytic domain. The binding of FGFRs to their ligands,
the FGFs, results in receptor dimerization and
activation, and intracellular signaling. The binding of
FGFs to FGFRs is promiscuous, in that a receptor may be
activated by several ligands and a ligand may bind to
more that one type of receptor. 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.

is part of a larger superfamily that includes the
catalytic domains of serine/threonine kinases (STKs),
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. The pseudokinase domain shows similarity to
protein kinases but lacks crucial residues for catalytic
activity. STRAD forms a complex with the scaffolding
protein MO25, and the STK, LKB1, resulting in the
activation of the kinase. In the complex, LKB1
phosphorylates and activates adenosine
monophosphate-activated protein kinases (AMPKs), which
regulate cell energy metabolism and cell polarity. LKB1
is a tumor suppressor linked to the rare inherited
disease, Peutz-Jeghers syndrome, which is characterized
by a predisposition to benign polyps and
hyperpigmentation of the buccal mucosa. There are two
forms of STRAD, alpha and beta, that complex with LKB1
and MO25. STRAD-beta is also referred to as ALS2CR2
(Amyotrophic lateral sclerosis 2 chromosomal region
