>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|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.

function. This subfamily is composed of CDK9 and CDK12
from higher eukaryotes, yeast BUR1, C-type plant CDKs
(CdkC), and similar proteins. CDK9, BUR1, and CdkC are
functionally equivalent. They act as a kinase for the
C-terminal domain of RNA polymerase II and participate
in regulating mutliple steps of gene expression
including transcription elongation and RNA processing.
CDK9 and CdkC associate with T-type cyclins while BUR1
associates with the cyclin BUR2. CDK12 is a unique CDK
that contains an arginine/serine-rich (RS) domain,
which is predominantly found in splicing factors. CDK12
interacts with cyclins L1 and L2, and participates in
regulating transcription and alternative splicing.

p42. It is a Cyclin-Dependent Kinase (CDK)-Activating
Kinase (CAK) which is essential for the activation of
CDK2. It is indispensable for cell growth and has been
implicated in the progression of glioblastoma
multiforme. In the heart, a splice variant of CCRK with
a different C-terminal half is expressed, this variant
promotes cardiac cell growth and survival and is
significantly down-regulated during the development of
heart failure.

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.

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

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

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

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

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.

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).

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

family of STKs that are regulated by their cognate
cyclins. Together, they are involved in the control of
cell-cycle progression, transcription, and neuronal
function. CDK4 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.

Protein Kinases (PKs), STE family, catalytic (c)

is part of a larger superfamily that includes the
catalytic domains of other protein serine/threonine

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.

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.

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

MAPKs based on the conserved phosphorylation motif
present in the activation loop, TEY and TDY. This
subfamily represents the TEY subtype and is further
subdivided into three groups (A, B, and C). Group A is
represented by AtMPK3, AtMPK6, Nicotiana tabacum BTF4

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

substrates. The MEKK1 subfamily is part of a larger
superfamily that includes the catalytic domains of
other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline

mitogen-activated protein kinase (MAPK) kinase kinase
(MAPKKK or MKKK or MAP3K), that phosphorylates and
activates 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. MEKK1
activates the extracellular signal-regulated kinase 1/2
(ERK1/2) and c-Jun N-terminal kinase (JNK) pathways by
activating their respective MAPKKs, MEK1/2 and
MKK4/MKK7, respectively. MEKK1 is important in
regulating cell survival and apoptosis. MEKK1 also
plays a role in cell migration, tissue maintenance and
homeostasis, and wound healing.

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

three MAPK subfamilies: extracellular signal-regulated
kinase (ERK), c-Jun N-terminal kinase (JNK), and p38.
In mammalian cells, there are seven MAPKKs (named
MKK1-7) and 20 MAPKKKs. Each MAPK subfamily can be

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

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

the core environmetal stress response (CESR). Hog1 is
the key element in the high osmolarity glycerol (HOG)

This PTKc family is part of a larger superfamily that
includes the catalytic domains of protein
serine/threonine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. They can
be classified into receptor and non-receptor tyr
kinases. PTKs play important roles in many cellular
processes including, lymphocyte activation, epithelium
growth and maintenance, metabolism control,
organogenesis regulation, survival, proliferation,
differentiation, migration, adhesion, motility, and
morphogenesis. Receptor tyr kinases (RTKs) are integral
membrane proteins which contain an extracellular
ligand-binding region, a transmembrane segment, and an
intracellular tyr kinase domain. RTKs are usually
activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain, leading to
intracellular signaling. Some RTKs are orphan receptors
with no known ligands. Non-receptor (or cytoplasmic)
tyr kinases are distributed in different intracellular
compartments and are usually multi-domain proteins
containing a catalytic tyr kinase domain as well as
various regulatory domains such as SH3 and SH2. PTKs
are usually autoinhibited and require a mechanism for
activation. In many PTKs, the phosphorylation of tyr
residues in the activation loop is essential for
optimal activity. Aberrant expression of PTKs is
associated with many development abnormalities and
cancers.

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.

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

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

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

sequence similarity with Cyclin-Dependent Kinases
(CDKs), which belong to a large family of STKs that are
regulated by their cognate cyclins. Together, CDKs and
cyclins are involved in the control of cell-cycle
progression, transcription, and neuronal function.
PFTAIRE-1 is widely expressed except in the spleen and
thymus. It is highly expressed in the brain, heart,
pancreas, testis, and ovary, and is localized in the
cytoplasm. It is regulated by cyclin D3 and is
inhibited by the p21 cell cycle inhibitor. It has also
been shown to interact with the membrane-associated
cyclin Y, which recruits the protein to the plasma
membrane.

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

in the regulation of macrophages and osteoclasts. It
leads to increases in gene transcription and protein
translation, and induces cytoskeletal remodeling.
CSF-1R signaling leads to a variety of cellular
responses including survival, proliferation, and
differentiation of target cells. It plays an important
role in innate immunity, tissue development and
function, and the pathogenesis of some diseases
including atherosclerosis and cancer. CSF-1R signaling
is also implicated in mammary gland development during

Kinases. Serine/Threonine Kinases (STKs),
Extracellular signal-regulated kinases 1 and 2 (ERK1/2)
and Fus3 subfamily, catalytic (c) domain. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. This
ERK1/2-like subfamily is part of a larger superfamily
that includes the catalytic domains of other protein
STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. This subfamily is composed
of the mitogen-activated protein kinases (MAPKs) ERK1,
ERK2, baker's yeast Fus3, and similar proteins. MAPK
pathways are important mediators of cellular responses
to extracellular signals. ERK1/2 activation is
preferentially by mitogenic factors, differentiation
stimuli, and cytokines, through a kinase cascade
involving the MAPK kinases MEK1/2 and a MAPK kinase
kinase from the Raf family. ERK1/2 have numerous
substrates, many of which are nuclear and participate
in transcriptional regulation of many cellular
processes. They regulate cell growth, cell
proliferation, and cell cycle progression from G1 to S
phase. Although the distinct roles of ERK1 and ERK2
have not been fully determined, it is known that ERK2
can maintain most functions in the absence of ERK1, and
that the deletion of ERK2 is embryonically lethal. The
MAPK, Fus3, regulates yeast mating processes including
mating-specific gene expression, G1 arrest, mating
projection, and cell fusion.

phosphoinositide 3-kinase. MAPKs are important
mediators of cellular responses to extracellular
signals. In plants, MAPKs are associated with
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.

domain of the Hsp90 co-chaperone Aha1 and related
proteins. This subfamily includes the C-terminal SRPBCC
(START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain of
Aha1, and related domains. Proteins in this group belong
to the SRPBCC domain superfamily of proteins which bind
hydrophobic ligands. SRPBCC domains have a deep
hydrophobic ligand-binding pocket. Aha1 is one of
several co-chaperones, which regulate the dimeric
chaperone Hsp90. Hsp90, Aha1, and other accessory
proteins interact in a chaperone cycle driven by ATP
binding and hydrolysis. Aha1 promotes dimerization of
the N-terminal domains of Hsp90, and stimulates its low
intrinsic ATPase activity. One Aha1 molecule binds per
Hsp90 dimer. The N- and C- terminal domains of Aha1
cooperatively bind across the dimer interface of Hsp90.
The C-terminal domain of Aha1 binds the N-terminal Hsp90
ATPase domain. Aha1 may regulate the dwell time of Hsp90
with client proteins. Aha1 may act as either a negative
or positive regulator of chaperone-dependent activation,
depending on the client protein; for example, it acts as
a negative regulator in the case of Saccharomyces
cerevisiae MAL63 MAL-activator, and acts as a positive
regulator in the case of glucocorticoid receptor and
v-Src kinase. The mechanisms by which these opposing
functions are achieved are unclear. Aha1 is upregulated
in a number of tumor lines co-incident with the
activation of several signaling kinases.

Serine/threonine kinases (STKs), MAP/ERK kinase kinase
4 (MEKK4) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The MEKK4 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. MEKK4 is a
mitogen-activated protein kinase (MAPK) kinase kinase
(MAPKKK or MKKK or MAP3K), that phosphorylates and
activates 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. MEKK4
activates the c-Jun N-terminal kinase (JNK) and p38
MAPK signaling pathways by directly activating their
respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. JNK and p38
are collectively known as stress-activated MAPKs, as
they are activated in response to a variety of
environmental stresses and pro-inflammatory cytokines.
MEKK4 also plays roles in the re-polarization of the
actin cytoskeleton in response to osmotic stress, in
the proper closure of the neural tube, in
cardiovascular development, and in immune responses.

Serine/threonine kinases (STKs), p21-activated kinase
(PAK) subfamily, Group II, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine residues on protein
substrates. The PAK subfamily is part of a larger
superfamily that includes the catalytic domains of
other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. PAKs are Rho
family GTPase-regulated kinases that serve as important
mediators in the function of Cdc42 (cell division cycle
42) and Rac. PAKs from higher eukaryotes are classified
into two groups (I and II), according to their
biochemical and structural features. Group II PAKs,
also called non-conventional PAKs, include PAK4, PAK5,
and PAK6. Group II PAKs contain PBD (p21-binding
domain) and catalytic domains, but lack other motifs
found in group I PAKs, such as an AID (autoinhibitory
domain) and SH3 binding sites. Since group II PAKs do
not contain an obvious AID, they may be regulated
differently from group I PAKs. While group I PAKs
interact with the SH3 containing proteins Nck, Grb2 and
PIX, no such binding has been demonstrated for group II
PAKs. Some known substrates of group II PAKs are also
substrates of group I PAKs such as Raf, BAD, LIMK and
GEFH1. Unique group II substrates include MARK/Par-1
and PDZ-RhoGEF. Group II PAKs play important roles in
filopodia formation, neuron extension, cytoskeletal
organization, and cell survival.

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