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.

JNK1 subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,

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

a lesser extent in the heart and testis. Mice deficient
in Jnk3 are protected against kainic acid-induced
seizures, stroke, sciatic axotomy neural death, and
neuronal death due to NGF deprivation, oxidative

TIF-IA which is involved in ribosomal RNA synthesis
regulation. Mice deficient in Jnk2 show protection
against arthritis, type 1 diabetes, atherosclerosis,

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.

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.

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.

of the MAPKs Sty1 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.

environmental and hormonal responses. AtMPK3 and
AtMPK6 are also key regulators for stomatal development
and patterning. Group B is represented by AtMPK4,
AtMPK13, and NtNTF6, among others. They may be involved
in both cell division and environmental stress
response. AtMPK4 also participates in regulating innate
immunity. Group C is represented by AtMPK1, AtMPK2,

They may also be involved in stress responses. AtMPK1
and AtMPK2 are activated following mechanical injury
and in the presence of stress chemicals such as
jasmonic acid, hydrogen peroxide and abscisic acid.
OsMAPK4 is also called OsMSRMK3 for Multiple
Stress-Responsive MAPK3.

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

preferentially by mitogenic factors, differentiation
stimuli, and cytokines, through a kinase cascade
involving the MAPK kinases MEK1/2 and a MAPK kinase
kinase from the Raf family. ERK1/2 have numerous
substrates, many of which are nuclear and participate
in transcriptional regulation of many cellular
processes. They regulate cell growth, cell
proliferation, and cell cycle progression from G1 to S
phase. Although the distinct roles of ERK1 and ERK2
have not been fully determined, it is known that ERK2
can maintain most functions in the absence of ERK1, and
that the deletion of ERK2 is embryonically lethal. The
MAPK, Fus3, regulates yeast mating processes including
mating-specific gene expression, G1 arrest, mating
projection, and cell fusion.

constitutively active and is not affected by
extracellular stimuli whereas ERK8 shows low basal
activity and is activated by DNA-damaging agents. ERK7

of estrogen receptor alpha while ERK8 down-regulates
the transcriptional co-activation androgen and

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

associated with tumor development. PAKs from higher
eukaryotes are classified into two groups (I and II),

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.

kinases, aminoglycoside phosphotransferase, choline

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

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.

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

gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK7 subfamily is
part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside

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

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,

is part of a larger superfamily that includes the

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.

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.

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

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

be classified into receptor and non-receptor tyr
kinases. PTKs play important roles in many cellular
processes including, lymphocyte activation, epithelium
growth and maintenance, metabolism control,
organogenesis regulation, survival, proliferation,
differentiation, migration, adhesion, motility, and
morphogenesis. Receptor tyr kinases (RTKs) are integral
membrane proteins which contain an extracellular
ligand-binding region, a transmembrane segment, and an
intracellular tyr kinase domain. RTKs are usually
activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain, leading to
intracellular signaling. Some RTKs are orphan receptors
with no known ligands. Non-receptor (or cytoplasmic)
tyr kinases are distributed in different intracellular
compartments and are usually multi-domain proteins
containing a catalytic tyr kinase domain as well as
various regulatory domains such as SH3 and SH2. PTKs
are usually autoinhibited and require a mechanism for
activation. In many PTKs, the phosphorylation of tyr
residues in the activation loop is essential for
optimal activity. Aberrant expression of PTKs is
associated with many development abnormalities and
cancers.

family of STKs that are regulated by their cognate
cyclins. Together, they are involved in the control of
cell-cycle progression, transcription, and neuronal
function. This subfamily is composed of CDK1 from
higher eukaryotes. CDK1 is also called Cell division
control protein 2 (Cdc2) or p34 protein kinase, and is
regulated by cyclins A, B, and E. The CDK1/cyclin A
complex controls G2 phase entry and progression.
CDK1/cyclin A2 has also been implicated as an important
regulator of S phase events. The CDK1/cyclin B complex
is critical for G2 to M phase transition. It induces
mitosis by activating nuclear enzymes that regulate
chromatin condensation, nuclear membrane degradation,
mitosis-specific microtubule and cytoskeletal
reorganization. CDK1 also associates with cyclin E and
plays a role in the entry into S phase. CDK1
transcription is stable throughout the cell cycle but
is modulated in some pathological conditions. It may
play a role in regulating apoptosis under these
conditions. In breast cancer cells, HER2 can mediate
apoptosis by inactivating CDK1. Activation of CDK1 may
contribute to HIV-1 induced apoptosis and neuronal
apoptosis in neurodegenerative diseases.

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. TAO1 is sometimes
referred to as prostate-derived sterile 20-like kinase
2 (PSK2). TAO1 activates the p38 MAPK through direct
interaction with and activation of MEK3. TAO1 is highly
expressed in the brain and may play a role in neuronal
apoptosis. TAO1 interacts with the checkpoint proteins
BubR1 and Mad2, and plays an important role in
regulating mitotic progression, which is required for
both chromosome congression and checkpoint-induced
anaphase delay. TAO1 may play a role in protecting
genomic stability.

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.

harbor an AID (autoinhibitory domain) or SH3 binding
sites. PAK5 is mainly expressed in the brain. It is not
required for viability, but together with PAK6, it is
required for normal levels of locomotion and activity,
and for learning and memory. PAK5 cooperates with Inca
(induced in neural crest by AP2) in the regulation of
cell adhesion and cytoskeletal organization in the
embryo and in neural crest cells during craniofacial
development. PAK5 may also play a role in controlling
the signaling of Raf-1, an effector of Ras, at the
mitochondria.

Vertebrate members contain an N-terminal catalytic

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

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

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.

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

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

cyclins. Together, they are involved in the control of
cell-cycle progression, transcription, and neuronal
function. CDK4 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.

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

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.

>gnl|CDD|173702 cd05611, STKc_Rim15_like, Catalytic domain of fungal Rim15-like
Protein Serine/Threonine Kinases. Serine/Threonine
Kinases (STKs), Microtubule-associated serine/threonine
(MAST) kinase subfamily, fungal Rim15-like kinases,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAST kinase
subfamily is part of a larger superfamily that includes
the catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. Members of this group
include Saccharomyces cerevisiae Rim15,
Schizosaccharomyces pombe cek1, and similar fungal
proteins. They contain a central catalytic domain,
which contains an insert relative to MAST kinases. In
addition, Rim15 contains a C-terminal signal receiver
(REC) domain while cek1 contains an N-terminal PAS
domain. Rim15 (or Rim15p) functions as a regulator of
meiosis. It acts as a downstream effector of PKA and
regulates entry into stationary phase (G0). Thus, it
plays a crucial role in regulating yeast proliferation,
differentiation, and aging. Cek1 may facilitate
progression of mitotic anaphase.
