>gnl|CDD|173733 cd07829, STKc_CDK_like, Catalytic domain of Cyclin-Dependent
protein Kinase-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase (CDK)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. CDKs belong to a large
family of STKs that are regulated by their cognate
cyclins. Together, they are involved in the control of
cell-cycle progression, transcription, and neuronal
function. CDKs are partly regulated by their
subcellular localization, which defines substrate
phosphorylation and the resulting specific function.
CDK1, CDK2, CDK4, and CDK6 have well-defined functions
in the cell cycle, such as the regulation of the early
G1 phase by CDK4 or CDK6, the G1/S phase transition by
CDK2, or the entry of mitosis by CDK1. They also
exhibit overlapping cyclin specificity and functions in
certain conditions. Knockout mice with a single CDK
deleted remain viable with specific phenotypes, showing
that some CDKs can compensate for each other. For
example, CDK4 can compensate for the loss of CDK6,
however, double knockout mice with both CDK4 and CDK6
deleted die in utero. CDK8 and CDK9 are mainly involved
in transcription while CDK5 is implicated in neuronal
function. CDK7 plays essential roles in both the cell
cycle as a CDK-Activating Kinase (CAK) and in
transcription as a component of the general
transcription factor TFIIH.

>gnl|CDD|143346 cd07841, STKc_CDK7, Catalytic domain of the Serine/Threonine
Kinase, Cyclin-Dependent protein Kinase 7.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 7 (CDK7) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
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
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. 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.

>gnl|CDD|173738 cd07835, STKc_CDK1_like, Catalytic domain of Cyclin-Dependent
protein Kinase 1-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 1 (CDK1)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK1 subfamily is
part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. CDKs belong to a large
family of STKs that are regulated by their cognate
cyclins. Together, they are involved in the control of
cell-cycle progression, transcription, and neuronal
function. This subfamily is composed of CDK1 from
higher eukaryotes, plants, and yeasts, as well as CDK2
and CDK3. CDK1 is also called Cell division control
protein 2 (Cdc2) or p34 protein kinase, and is
regulated by cyclins A, B, and E. The CDK1/cyclin A
complex controls G2 phase entry and progression while
the CDK1/cyclin B complex is critical for G2 to M phase
transition. CDK2 is regulated by cyclin E or cyclin A.
Upon activation by cyclin E, it phosphorylates the
retinoblastoma (pRb) protein which activates E2F
mediated transcription and allows cells to move into S
phase. The CDK2/cyclin A complex plays a role in
regulating DNA replication. Studies in knockout mice
revealed that CDK1 can compensate for the loss of the
cdk2 gene as it can also bind cyclin E and drive G1 to
S phase transition. CDK3 is regulated by cyclin C and
it phosphorylates pRB specifically during the G0/G1
transition. This phosphorylation is required for cells
to exit G0 efficiently and enter the G1 phase.

>gnl|CDD|173751 cd07860, STKc_CDK2_3, Catalytic domain of the Serine/Threonine
Kinases, Cyclin-Dependent protein Kinase 2 and 3.
Serine/Threonine Kinases (STKs), Cyclin-dependent
protein kinase 2 (CDK2) and CDK3 subfamily, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK2/3 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. 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.

Kinase, Cyclin-Dependent protein Kinase 5.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 5 (CDK5) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK5 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. CDK5 is unusual in that it is regulated by
non-cyclin proteins, p35 and p39. It is highly
expressed in the nervous system and is critical in
normal neural development and function. It plays a role
in neuronal migration and differentiation, and is also
important in synaptic plasticity and learning. CDK5
also participates in protecting against cell death and
promoting angiogenesis. Impaired CDK5 activity is
implicated in Alzheimer's disease, amyotrophic lateral
sclerosis, Parkinson's disease, Huntington's disease
and acute neuronal injury.

kinase 7 (CRK7) or Cdc2-related kinase
arginine/serine-rich (CrkRS). It is a unique CDK that
contains an arginine/serine-rich (RS) domain, which is
predominantly found in splicing factors. CDK12 is
widely expressed in tissues. It interacts with cyclins
L1 and L2, and plays roles in regulating transcription
and alternative splicing.

cell growth and proliferation, and acts through the
G2/M phase of the cell cycle. CDK10 has also been
identified as an important factor in endocrine therapy
resistance in breast cancer. CDK10 silencing increases
the transcription of c-RAF and the activation of the
p42/p44 MAPK pathway, which leads to antiestrogen
resistance. Patients who express low levels of CDK10
relapse early on tamoxifen.

MAPKs during signaling cascades that are important in
mediating cellular responses to extracellular signals.
Fission yeast Cdc7 is essential for cell division by
playing a key role in the initiation of septum
formation and cytokinesis. Budding yeast Cdc15
functions to coordinate mitotic exit with cytokinesis.
Arabidopsis MAPKKK epsilon is required for pollen

mediators of cellular responses to extracellular
signals. Human MAPK15 is also called Extracellular
signal Regulated Kinase 8 (ERK8) while the rat protein
is called ERK7. ERK7 and ERK8 display both similar and
different biochemical properties. They
autophosphorylate and activate themselves and do not
require upstream activating kinases. ERK7 is
constitutively active and is not affected by
extracellular stimuli whereas ERK8 shows low basal
activity and is activated by DNA-damaging agents. ERK7
and ERK8 also have different substrate profiles. Genome
analysis shows that they are orthologs with similar
gene structures. ERK7 and ERK 8 may be involved in the
signaling of some nuclear receptor transcription
factors. ERK7 regulates hormone-dependent degradation
of estrogen receptor alpha while ERK8 down-regulates
the transcriptional co-activation androgen and
glucocorticoid receptors.

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.

Cyclin-Dependent protein Kinase (CDK) that is
functionally equivalent to mammalian CDK9. It
associates with the cyclin BUR2. BUR genes were
orginally identified in a genetic screen as factors
involved in general transcription. The BUR1/BUR2

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.

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

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

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.

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

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

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

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.

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.

GTPase-regulated kinases that serve as important

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

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.

mediators of cellular responses to extracellular

has a unique C-terminal extension, making it
approximately twice as big as other MAPKs. This
extension contains transcriptional activation
capability which is inhibited by the N-terminal half.
ERK5 is activated in response to growth factors and
stress by a cascade that leads to its phosphorylation
by the MAP2K MEK5, which in turn is regulated by the
MAP3Ks MEKK2 and MEKK3. Activated ERK5 phosphorylates
its targets including myocyte enhancer factor 2 (MEF2),
Sap1a, c-Myc, and RSK. It plays a role in EGF-induced
cell proliferation during the G1/S phase transition.
Studies on knockout mice revealed that ERK5 is
essential for cardiovascular development and plays an
important role in angiogenesis. It is also critical for
neural differentiation and survival. The ERK5 pathway
has been implicated in the pathogenesis of many
diseases including cancer, cardiac hypertrophy, and
atherosclerosis.

Kinase, Cyclin-Dependent protein Kinase 9.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 9 (CDK9) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK9 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. CDK9 together with a cyclin partner (cyclin
T1, T2a, T2b, or K) is the main component of distinct
positive transcription elongation factors (P-TEFb),
which function as Ser2 C-terminal domain kinases of RNA
polymerase II. P-TEFb participates in multiple steps of
gene expression including transcription elongation,
mRNA synthesis, processing, export, and translation. It
also plays a role in mediating cytokine induced
transcription networks such as IL6-induced STAT3
signaling. In addition, the CDK9/cyclin T2a complex
promotes muscle differentiation and enhances the
function of some myogenic regulatory factors.

dual-specificity MAP kinase kinases and similar
proteins. Protein kinases (PKs), MAP kinase kinase
(MAPKK) subfamily, Plant MAPKKs and similar proteins,
catalytic (c) domain. PKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine or
tyrosine residues on protein substrates. The MAPKK
subfamily is part of a larger superfamily that includes
the catalytic domains of other protein serine/threonine
kinases, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. The mitogen-activated
protein (MAP) kinase signaling pathways are important
mediators of cellular responses to extracellular
signals. The pathways involve a triple kinase core
cascade comprising of the MAP kinase (MAPK), which is
phosphorylated and activated by a MAPK kinase (MAPKK or
MKK), which itself is phosphorylated and activated by a
MAPK kinase kinase (MAPKKK or MKKK). Members of this
group include MAPKKs from plants, kinetoplastids,
alveolates, and mycetozoa. The MAPKK, LmxPK4, from
Leishmania mexicana, is important in differentiation
and virulence. Dictyostelium discoideum MEK1 is
required for proper chemotaxis. MEK1 null mutants
display severe defects in cell polarization and
directional movement. Plants contain multiple MAPKKs
like other eukaryotes. The Arabidopsis genome encodes
for 10 MAPKKs while poplar and rice contain 13 MAPKKs
each. The functions of these proteins have not been
fully elucidated. There is evidence to suggest that
MAPK cascades are involved in plant stress responses.
In Arabidopsis, MKK3 plays a role in pathogen
signaling, MKK2 is involved in cold and salt stress
signaling, MKK4/MKK5 participates in innate immunity,
and MKK7 regulates basal and systemic acquired
resistance.

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

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.

contain an N-terminal catalytic domain and a C-terminal

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. MAP4K5, also called germinal center
kinase-related enzyme (GCKR), has been shown to
activate the MAPK c-Jun N-terminal kinase (JNK). MAP4K5
also facilitates Wnt signaling in B cells, and may
therefore be implicated in the control of cell fate,
proliferation, and polarity.

This PTKc family is part of a larger superfamily that

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.

plays a role in cell proliferation and survival. In
response to DNA damage or oxidative stress, Abl is
transported to the nucleus where it induces apoptosis.
In chronic myelogenous leukemia (CML) patients, an
aberrant translocation results in the replacement of
the first exon of Abl with the BCR (breakpoint cluster
region) gene. The resulting BCR-Abl fusion protein is
constitutively active and associates into tetramers,
resulting in a hyperactive kinase sending a continuous
signal. This leads to uncontrolled proliferation,
morphological transformation and anti-apoptotic
effects. BCR-Abl is the target of selective inhibitors,
such as imatinib (Gleevec), used in the treatment of
CML. Abl2, also known as ARG (Abelson-related gene), is
thought to play a cooperative role with Abl in the
proper development of the nervous system. The Tel-ARG
fusion protein, resulting from reciprocal translocation
between chromosomes 1 and 12, is associated with acute
myeloid leukemia (AML). The TEL gene is a frequent
fusion partner of other tyr kinase oncogenes, including
Tel/Abl, Tel/PDGFRbeta, and Tel/Jak2, found in patients
with leukemia and myeloproliferative disorders.

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

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.

simply binding to them. As a negative regulator of Src
kinases, Chk may play important roles in cell
proliferation, survival, and differentiation, and
consequently, in cancer development and progression. Chk
is expressed in brain and hematopoietic cells. Studies
in mice reveal that Chk is not functionally redundant
with Csk and that it plays an important role as a
regulator of immune responses. Chk also plays a role in
neural differentiation in a manner independent of Src by
enhancing Mapk activation via Ras-mediated signaling.

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

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.

named alpha, beta, gamma, and delta. p38delta, also
called MAPK13, is found in skeletal muscle, heart,
lung, testis, pancreas, and small intestine. It
regulates microtubule function by phosphorylating Tau.
It activates the c-jun promoter and plays a role in G2
cell cycle arrest. It also controls the degration of
c-Myb, which is associated with myeloid leukemia and
poor prognosis in colorectal cancer. p38delta is the

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)

Activated Hog1 accumulates in the nucleus and regulates
stress-induced transcription. The HOG pathway is
mediated by two transmembrane osmosensors, Sln1 and

signaling. There are at least 23 FGFs and four types of
FGFRs. The binding of FGFs to FGFRs is promiscuous, in
that a receptor may be activated by several ligands and
a ligand may bind to more that one type of receptor.
FGF/FGFR signaling is important in the regulation of
embryonic development, homeostasis, and regenerative
processes. Depending on the cell type and stage, FGFR
signaling produces diverse cellular responses including
proliferation, growth arrest, differentiation, and
apoptosis. Aberrant signaling leads to many human
diseases such as skeletal, olfactory, and metabolic
disorders, as well as cancer.

Serine/Threonine Kinase, Thousand-and-one amino acids
2. Serine/threonine kinases (STKs), thousand-and-one
amino acids 2 (TAO2) subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl
group from ATP to serine/threonine residues on protein
substrates. The TAO subfamily is part of a larger
superfamily that includes the catalytic domains of
other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. TAO proteins
possess mitogen-activated protein kinase (MAPK) kinase
kinase (MAPKKK or MAP3K or MKKK) activity. MAPK
signaling cascades are important in mediating cellular
responses to extracellular signals. Human TAO2 is also
known as prostate-derived Ste20-like kinase (PSK) and
was identified in a screen for overexpressed RNAs in
prostate cancer. TAO2 activates both p38 and c-Jun
N-terminal kinase (JNK), by phosphorylating and
activating the respective MAP/ERK kinases (MEKs, also
known as MKKs or MAPKKs), MEK3/MEK6 and MKK4/MKK7. TAO2
contains a long C-terminal extension with
autoinhibitory segments. It is activated by the release
of this inhibition and the phosphorylation of its
activation loop serine. TAO2 functions as a regulator
of actin cytoskeletal and microtubule organization. In
addition, it regulates the transforming growth
factor-activated kinase 1 (TAK1), which is a MAPKKK
that plays an essential role in the signaling pathways
of tumor necrosis factor (TNF), interleukin 1 (IL-1),
and Toll-like receptor (TLR).

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.

mediators of cellular responses to extracellular

cascade comprising the MAP kinase (MAPK), which is
phosphorylated and activated by a MAPK kinase (MAPKK or
MKK), which itself is phosphorylated and activated by a
MAPK kinase kinase (MAPKKK or MKKK). MEK1 is a
dual-specificity PK that phosphorylates and activates
the downstream targets, extracellular signal-regulated
kinase (ERK) 1 and ERK2, on specific threonine and
tyrosine residues. The ERK cascade starts with
extracellular signals including growth factors,
hormones, and neurotransmitters, which act through
receptors and ion channels to initiate intracellular
signaling that leads to the activation at the MAPKKK
(Raf-1 or MOS) level, which leads to the transmission
of signals to MEK1, and finally to ERK1/2. The ERK
cascade plays an important role in cell proliferation,
differentiation, oncogenic transformation, and cell
cycle control, as well as in apoptosis and cell
survival under certain conditions. Gain-of-function
mutations in genes encoding ERK cascade proteins,
including MEK1, cause cardiofaciocutaneous (CFC)
syndrome, a condition leading to multiple congenital
anomalies and mental retardation in patients. MEK1 also
plays a role in cell cycle control.

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

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

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

proteins are orphan receptor tyr kinases (RTKs)
containing an extracellular region with
immunoglobulin-like, cysteine-rich, and kringle
domains, a transmembrane segment, and an intracellular
catalytic domain. Ror RTKs are unrelated to the nuclear
receptor subfamily called retinoid-related orphan
receptors (RORs). RTKs are usually activated through
ligand binding, which causes dimerization and
autophosphorylation of the intracellular tyr kinase
catalytic domain. Ror kinases are expressed in many
tissues during development. They play important roles
in bone and heart formation. Mutations in human Ror2
result in two different bone development genetic
disorders, recessive Robinow syndrome and brachydactyly
type B. Drosophila Ror is expressed only in the
developing nervous system during neurite outgrowth and
neuronal differentiation, suggesting a role for
Drosophila Ror in neural development. More recently,
mouse Ror1 and Ror2 have also been found to play an
important role in regulating neurite growth in central
neurons. Ror1 and Ror2 are believed to have some
overlapping and redundant functions.

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.

MAPKs are important mediators of cellular responses to

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

cause cardiofaciocutaneous (CFC) syndrome, a condition
leading to multiple congenital anomalies and mental

amino acids 3 (TAO3) subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl
group from ATP to serine/threonine residues on protein
substrates. The TAO subfamily is part of a larger
superfamily that includes the catalytic domains of
other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. TAO proteins
possess mitogen-activated protein kinase (MAPK) kinase
kinase (MAPKKK or MAP3K or MKKK) activity. MAPK
signaling cascades are important in mediating cellular
responses to extracellular signals. TAO3 is also known
as JIK (JNK inhibitory kinase) or KFC (kinase from
chicken). It specifically activates c-Jun N-terminal
kinase (JNK), presumably by phosphorylating and
activating MKK4/MKK7. In Saccharomyces cerevisiae, TAO3
is a component of the RAM (regulation of Ace2p activity
and cellular morphogenesis) signaling pathway. TAO3 is
upregulated in retinal ganglion cells after axotomy,
and may play a role in apoptosis.

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.

MAPK6 is also called ERK3 or p97MAPK. MAPK4 and MAPK6
are atypical MAPKs that are not regulated by MAP2Ks.
MAPK6 is expressed ubiquitously with highest amounts in
brain and skeletal muscle. It may be involved in the
control of cell differentiation by negatively
regulating cell cycle progression in certain
conditions. It may also play a role in glucose-induced
insulin secretion. MAPK6 and MAPK4 cooperate to
regulate the activity of MAPK-activated protein kinase
5 (MK5), leading to its relocation to the cytoplasm and

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

which are receptor tyr kinases (RTKs) containing an

transmembrane helix, and a cytoplasmic region with a
tyr kinase domain and a regulatory C-terminal tail.
Unlike other tyr kinases, phosphorylation of the
activation loop of EGFR proteins is not critical to
their activation. Instead, they are activated by
ligand-induced dimerization, leading to the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. Ligands that bind HER4 fall into two groups,
the neuregulins (or heregulins) and some EGFR (HER1)
ligands including betacellulin, HBEGF, and epiregulin.
All four neuregulins (NRG1-4) interact with HER4. Upon
ligand binding, HER4 forms homo- or heterodimers with
other HER proteins. HER4 is essential in embryonic
development. It is implicated in mammary gland,
cardiac, and neural development. As a postsynaptic
receptor of NRG1, HER4 plays an important role in
synaptic plasticity and maturation. The impairment of
NRG1/HER4 signaling may contribute to schizophrenia.

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

Kinase, Discoidin Domain Receptor 2. Protein Tyrosine
Kinase (PTK) family; mammalian Discoidin Domain
Receptor 2 (DDR2) and homologs; 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. DDR2 is
a member of the DDR subfamily, which are receptor tyr
kinases (RTKs) containing an extracellular discoidin
homology domain, a transmembrane segment, an extended
juxtamembrane region, and an intracellular catalytic
domain. The binding of the ligand, collagen, to DDRs
results in a slow but sustained receptor activation.
DDR2 binds mostly to fibrillar collagens. More
recently, it has been reported to also bind collagen X.
DDR2 is widely expressed in many tissues with the
highest levels found in skeletal muscle, skin, kidney
and lung. It is important in cell proliferation and
development. Mice, with a deletion of DDR2, suffer from
dwarfism and delayed healing of epidermal wounds. DDR2
also contributes to collagen (type I) regulation by
inhibiting fibrillogenesis and altering the morphology
of collagen fibers. It is also expressed in immature
dendritic cells (DCs), where it plays a role in DC
activation and function.

(HER, ErbB) subfamily members include EGFR (HER1,
ErbB1), HER2 (ErbB2), HER3 (ErbB3), HER4 (ErbB4), and
similar proteins. The PTKc family is part of a larger
superfamily that includes the catalytic domains of
other kinases such as protein serine/threonine kinases,
RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group
from ATP to tyrosine (tyr) residues in protein
substrates. The EGFR proteins are receptor tyr kinases
(RTKs) containing an extracellular EGF-related
ligand-binding region, a transmembrane helix, and a
cytoplasmic region with a tyr kinase domain and a
regulatory C-terminal tail. Unlike other tyr kinases,
phosphorylation of the activation loop of EGFR proteins
is not critical to their activation. Instead, they are
activated by ligand-induced dimerization, resulting in
the phosphorylation of tyr residues in the C-terminal
tail, which serve as binding sites for downstream
signaling molecules. Collectively, they can recognize a
variety of ligands including EGF, TGFalpha, and
neuregulins, among others. All four subfamily members
can form homo- or heterodimers. HER3 contains an
impaired kinase domain and depends on its
heterodimerization partner for activation. EGFR
subfamily members are involved in signaling pathways
leading to a broad range of cellular responses
including cell proliferation, differentiation,
migration, growth inhibition, and apoptosis. Gain of
function alterations, through their overexpression,
deletions, or point mutations in their kinase domains,
have been implicated in various cancers. These
receptors are targets of many small molecule inhibitors
and monoclonal antibodies used in cancer therapy.

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

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

protein kinases (MAPKs) that are involved in many
stress-activated responses including those during
inflammation, neurodegeneration, apoptosis, and
persistent pain sensitization, among others. Vetebrates
harbor three different JNK genes (Jnk1, Jnk2, and
Jnk3). JNK1, like JNK2, is expressed in every cell and
tissue type. Initially it was thought that JNK1 and
JNK2 were functionally redundant as mice deficient in
either genes (Jnk1 or Jnk2) could survive but
disruption of both genes resulted in lethality.
However, recent studies have shown that JNK1 and JNK2
perform distinct functions through specific binding
partners and substrates. 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.

harbor an AID (autoinhibitory domain) or SH3 binding
sites. PAK4 regulates cell morphology and cytoskeletal
organization. It is essential for embryonic viability
and proper neural development. Mice lacking PAK4 die
due to defects in the fetal heart. In addition, their
spinal cord motor neurons showed failure to
differentiate and migrate. PAK4 also plays a role in
cell survival and tumorigenesis. It is overexpressed in
many primary tumors including colon, esophageal, and

protein (MAP) kinase signaling pathways are important
mediators of cellular responses to extracellular

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)

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

kinase-like Protein Tyrosine Kinases. Protein Tyrosine
Kinase (PTK) family; C-terminal Src kinase (Csk)
subfamily; catalytic (c) domain. The Csk subfamily is
composed of Csk, Chk, and similar proteins. The PTKc
family is part of a larger superfamily that includes
the catalytic domains of other kinases such as protein
serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Csk
subfamily kinases are cytoplasmic (or nonreceptor) tyr
kinases containing the Src homology domains, SH3 and
SH2, N-terminal to the catalytic tyr kinase domain.
They negatively regulate the activity of Src kinases
that are anchored to the plasma membrane. To inhibit
Src kinases, Csk and Chk are translocated to the
membrane via binding to specific transmembrane
proteins, G-proteins, or adaptor proteins near the
membrane. Csk catalyzes the tyr phosphorylation of the
regulatory C-terminal tail of Src kinases, resulting in
their inactivation. Chk inhibit Src kinases using a
noncatalytic mechanism by simply binding to them. As
negative regulators of Src kinases, Csk and Chk play
important roles in cell proliferation, survival, and
differentiation, and consequently, in cancer
development and progression.

>gnl|CDD|198225 cd10362, SH2_Src_Lck, Src homology 2 (SH2) domain in lymphocyte
cell kinase (Lck). Lck is a member of the Src
non-receptor type tyrosine kinase family of proteins.
It is expressed in the brain, T-cells, and NK cells.
The unique domain of Lck mediates its interaction with
two T-cell surface molecules, CD4 and CD8. It
associates with their cytoplasmic tails on CD4 T helper
cells and CD8 cytotoxic T cells to assist signaling
from the T cell receptor (TCR) complex. When the T cell
receptor is engaged by the specific antigen presented
by MHC, Lck phosphorylase the intracellular chains of
the CD3 and zeta-chains of the TCR complex, allowing
ZAP-70 to bind them. Lck then phosphorylates and
activates ZAP-70, which in turn phosphorylates Linker
of Activated T cells (LAT), a transmembrane protein
that serves as a docking site for proteins including:
Shc-Grb2-SOS, PI3K, and phospholipase C (PLC). The
tyrosine phosphorylation cascade culminates in the
intracellular mobilization of a calcium ions and
activation of important signaling cascades within the
lymphocyte, including the Ras-MEK-ERK pathway, which
goes on to activate certain transcription factors such
as NFAT, NF-kappaB, and AP-1. These transcription
factors regulate the production cytokines such as
Interleukin-2 that promote long-term proliferation and
differentiation of the activated lymphocytes. The
N-terminal tail of Lck is myristoylated and
palmitoylated and it tethers the protein to the plasma
membrane of the cell. Lck also contains a SH3 domain, a
SH2 domain, and a C-terminal tyrosine kinase domain.
Lck has 2 phosphorylation sites, the first an
autophosphorylation site that is linked to activation
of the protein and the second which is phosphorylated
by Csk, which inhibits it. Lck is also inhibited by
SHP-1 dephosphorylation and by Cbl ubiquitin ligase,
which is part of the ubiquitin-mediated pathway. In
general SH2 domains are involved in signal
transduction. They typically bind pTyr-containing
ligands via two surface pockets, a pTyr and hydrophobic
binding pocket, allowing proteins with SH2 domains to
localize to tyrosine phosphorylated sites.

alphabeta heterodimers. Binding of the ligand (insulin,
IGF-1, or IGF-2) to the extracellular alpha subunit
activates the intracellular tyr kinase domain of the

to autophosphorylation, stimulating downstream kinase
activities, which initiate signaling cascades and
biological function. InsR and IGF-1R, which share 84%
sequence identity in their kinase domains, display
physiologically distinct yet overlapping functions in
cell growth, differentiation, and metabolism. InsR
activation leads primarily to metabolic effects while
IGF-1R activation stimulates mitogenic pathways. In

(e) SDRs. Nucleoside-diphosphate-sugar 4-epimerase has
the characteristic active site tetrad and NAD-binding
motif of the extended SDR, and is related to more
specifically defined epimerases such as UDP-glucose 4
epimerase (aka UDP-galactose-4-epimerase), which
catalyzes the NAD-dependent conversion of UDP-galactose
to UDP-glucose, the final step in Leloir galactose
synthesis. This subgroup includes Escherichia coli
055:H7 Gne, a UDP-GlcNAc 4-epimerase, essential for O55
antigen synthesis. Extended SDRs are distinct from
classical SDRs. In addition to the Rossmann fold
(alpha/beta folding pattern with a central beta-sheet)
core region typical of all SDRs, extended SDRs have a
less conserved C-terminal extension of approximately 100
amino acids. Extended SDRs are a diverse collection of
proteins, and include isomerases, epimerases,
oxidoreductases, and lyases; they typically have a
TGXXGXXG cofactor binding motif. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold, an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Sequence identity between different
SDR enzymes is typically in the 15-30% range; they
catalyze a wide range of activities including the
metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase numbering). In
addition to the Tyr and Lys, there is often an upstream
Ser and/or an Asn, contributing to the active site;
while substrate binding is in the C-terminal region,
which determines specificity. The standard reaction
mechanism is a 4-pro-S hydride transfer and proton relay
involving the conserved Tyr and Lys, a water molecule
stabilized by Asn, and nicotinamide. Atypical SDRs
generally lack the catalytic residues characteristic of
the SDRs, and their glycine-rich NAD(P)-binding motif is
often different from the forms normally seen in
classical or extended SDRs. Complex (multidomain) SDRs
such as ketoreductase domains of fatty acid synthase
have a GGXGXXG NAD(P)-binding motif and an altered
active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

which are receptor tyr kinases (RTKs) containing an
extracellular EGF-related ligand-binding region, a
transmembrane helix, and a cytoplasmic region with a
tyr kinase domain and a regulatory C-terminal tail.
Unlike other tyr kinases, phosphorylation of the
activation loop of EGFR proteins is not critical to
their activation. Instead, they are activated by
ligand-induced dimerization, leading to the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. HER2 does not bind to any known EGFR
subfamily ligands, but contributes to the kinase
activity of all possible heterodimers. It acts as the
preferred partner with other ligand-bound EGFR proteins
and functions as a signal amplifier, with the HER2-HER3
heterodimer being the most potent pair in mitogenic
signaling. HER2 plays an important role in cell
development, proliferation, survival and motility.
Overexpression of HER2 results in its activation and
downstream signaling, even in the absence of ligand.
HER2 overexpression, mainly due to gene amplification,
has been shown in a variety of human cancers. Its role
in breast cancer is especially well-documented. HER2 is
up-regulated in about 25% of breast tumors and is
associated with increases in tumor aggressiveness,
recurrence and mortality. HER2 is a target for
monoclonal antibodies and small molecule inhibitors,
which are being developed as treatments for cancer. The
first humanized antibody approved for clinical use is
Trastuzumab (Herceptin), which is being used in
combination with other therapies to improve the
survival rates of patients with HER2-overexpressing
breast cancer.

mice reveal that Ryk is essential in skeletal,
craniofacial, and cardiac development. Thus, it appears
Ryk is involved in signal transduction despite its lack
of kinase activity. Ryk may function as an accessory
protein that modulates the signals coming from
catalytically active partner RTKs such as the Eph
receptors.

>gnl|CDD|173647 cd05091, PTKc_Ror2, Catalytic domain of the Protein Tyrosine
Kinase, Receptor tyrosine kinase-like Orphan Receptor
2. Protein Tyrosine Kinase (PTK) family; Receptor
tyrosine kinase-like Orphan Receptor 2 (Ror2);
catalytic (c) domain. The PTKc family is part of a
larger superfamily that includes the catalytic domains
of other kinases such as protein serine/threonine
kinases, RIO kinases, and phosphoinositide 3-kinase
(PI3K). PTKs catalyze the transfer of the
gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. Ror proteins are orphan
receptor tyr kinases (RTKs) containing an extracellular
region with immunoglobulin-like, cysteine-rich, and
kringle domains, a transmembrane segment, and an
intracellular catalytic domain. Ror RTKs are unrelated
to the nuclear receptor subfamily called
retinoid-related orphan receptors (RORs). RTKs are
usually activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain. Ror2 plays
important roles in skeletal and heart formation.
Ror2-deficient mice show widespread bone abnormalities,
ventricular defects in the heart, and respiratory
dysfunction. Mutations in human Ror2 result in two
different bone development genetic disorders, recessive
Robinow syndrome and brachydactyly type B. Ror2 is also
implicated in neural development.

>gnl|CDD|143383 cd07878, STKc_p38beta_MAPK11, Catalytic domain of the
Serine/Threonine Kinase, p38beta Mitogen-Activated
Protein Kinase. Serine/Threonine Kinases (STKs),
p38beta subfamily, catalytic (c) domain. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
p38beta 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 are activated by the MAPK
kinases MKK3 and MKK6, which in turn are activated by
upstream MAPK kinase kinases including TAK1, ASK1, and
MLK3, in response to cellular stresses or inflammatory
cytokines. Vertebrates contain four isoforms of p38,
named alpha, beta, gamma, and delta. p38beta, also
called MAPK11, is widely expressed in tissues and shows
more similarity with p38alpha than with the other
isoforms. Both are sensitive to pyridinylimidazoles and
share some common substrates such as MAPK activated
protein kinase 2 (MK2) and the transcription factors
ATF2, c-Fos and, ELK-1. p38beta is involved in
regulating the activation of the cyclooxygenase-2
promoter and the expression of TGFbeta-induced
alpha-smooth muscle cell actin.
