>gnl|CDD|173690 cd05599, STKc_NDR_like, Catalytic domain of Nuclear Dbf2-Related
kinase-like Protein Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Nuclear Dbf2-Related
(NDR) kinase subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The NDR 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. NDR kinase contains an N-terminal regulatory
(NTR) domain and an insert within the catalytic domain
that contains an auto-inhibitory sequence. Like many
other AGC kinases, NDR kinase requires phosphorylation
at two sites, the activation loop (A-loop) and the
hydrophobic motif (HM), for activity. NDR kinases
regulate mitosis, cell growth, embryonic development,
and neurological processes. They are also required for
proper centrosome duplication. Higher eukaryotes contain
two NDR isoforms, NDR1 and NDR2. This subfamily also
contains fungal NDR-like kinases.

Serine/Threonine Kinase, Nuclear Dbf2-Related kinase 2.
Serine/Threonine Kinases (STKs), NDR kinase subfamily,
NDR2 isoform, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The NDR
subfamily is part of a larger superfamily that includes
the catalytic domains of other protein STKs, protein

contain two NDR isoforms, NDR1 and NDR2. Both isoforms
play a role in proper centrosome duplication. In
addition, NDR2 plays a role in regulating neuronal
growth and differentiation, as well as in facilitating
neurite outgrowth. It is also implicated in fear
conditioning as it contributes to the coupling of
neuronal morphological changes with fear-memory
consolidation. NDR2 is also referred to as STK38-like.

highly expressed in thymus, muscle, lung and spleen. It
is not an essential protein because mice deficient of
NDR1 remain viable and fertile. However, these mice
develop T-cell lymphomas and appear to be hypersenstive
to carcinogenic treatment. NDR1 appears to act as a
tumor suppressor. NDR1 is also called STK38.

using a screen for genes whose inactivation led to
overproliferation of cells. In tetrapods, there are two
LATS isoforms, LATS1 and LATS2. Inactivation of LATS1 in
mice results in the development of various tumors,
including sarcomas and ovarian cancer. LATS functions as
a tumor suppressor and is implicated in cell cycle
regulation.

Serine/Threonine Kinases. Serine/Threonine Kinases
(STKs), AGC (Protein Kinases A, G and C) family,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The AGC family 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 (PI3K). Members of
this family include cAMP-dependent Protein Kinase (PKA),
cGMP-dependent Protein Kinase (PKG), Protein Kinase C
(PKC), Protein Kinase B (PKB), G protein-coupled
Receptor Kinase (GRK), Serum- and Glucocorticoid-induced
Kinase (SGK), and 70 kDa ribosomal Protein S6 Kinase
(p70S6K or S6K), among others. AGC kinases share an
activation mechanism based on the phosphorylation of up
to three sites: the activation loop (A-loop), the
hydrophobic motif (HM) and the turn motif.
Phosphorylation at the A-loop is required of most AGC
kinases, which results in a disorder-to-order transition
of the A-loop. The ordered conformation results in the
access of substrates and ATP to the active site. A
subset of AGC kinases with C-terminal extensions
containing the HM also requires phosphorylation at this
site. Phosphorylation at the HM allows the C-terminal
extension to form an ordered structure that packs into
the hydrophobic pocket of the catalytic domain, which
then reconfigures the kinase into an active bi-lobed
state. In addition, growth factor-activated AGC kinases
such as PKB, p70S6K, RSK, MSK, PKC, and SGK, require
phosphorylation at the turn motif (also called tail or
zipper site), located N-terminal to the HM at the
C-terminal extension. AGC kinases regulate many cellular
processes including division, growth, survival,
metabolism, motility, and differentiation. Many are
implicated in the development of various human diseases.

protein kinase-like Protein Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Myotonic Dystrophy
protein kinase (DMPK)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The DMPK-like subfamily
is part of a larger superfamily that includes the
catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. The DMPK-like subfamily is
composed of DMPK and DMPK-related cell division control
protein 42 (Cdc42) binding kinase (MRCK). Three
isoforms of MRCK are known, named alpha, beta and
gamma. The DMPK gene is implicated in myotonic
dystrophy 1 (DM1), an inherited multisystemic disorder
with symptoms that include muscle hyperexcitability,
progressive muscle weakness and wasting, cataract
development, testicular atrophy, and cardiac conduction
defects. The genetic basis for DM1 is the mutational
expansion of a CTG repeat in the 3'-UTR of DMPK. DMPK
is expressed in skeletal and cardiac muscles, and in
central nervous tissues. The functional role of DMPK is
not fully understood. It may play a role in the signal
transduction and homeostasis of calcium. MRCK is
activated via interaction with the small GTPase Cdc42.
MRCK/Cdc42 signaling mediates myosin-dependent cell
motility. MRCKgamma is expressed in heart and skeletal
muscles, unlike MRCKalpha and MRCKbeta, which are
expressed ubiquitously.

Inactivation of LATS1 in mice results in the development
of various tumors, including sarcomas and ovarian
cancer. Promoter methylation, loss of heterozygosity,
and missense mutations targeting the LATS1 gene have
also been found in human sarcomas and ovarian cancers.
In addition, decreased expression of LATS1 is associated
with an aggressive phenotype and poor prognosis. LATS1
induces G2 arrest and promotes cytokinesis. It may be a

aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. The MAST kinase subfamily
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.

Serine/Threonine Kinase, Rho-associated coiled-coil
containing protein kinase. Serine/Threonine Kinases
(STKs), Rho-associated coiled-coil containing protein
kinase (ROCK) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The ROCK 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. ROCK is also referred to as Rho-associated
kinase or simply as Rho kinase. It contains an
N-terminal extension, a catalytic kinase domain, and a
long C-terminal extension, which contains a coiled-coil
region encompassing a Rho-binding domain (RBD) and a
pleckstrin homology (PH) domain. ROCK is auto-inhibited
by the RBD and PH domain interacting with the catalytic
domain. It is activated via interaction with Rho GTPases
and is involved in many cellular functions including
contraction, adhesion, migration, motility,
proliferation, and apoptosis. The ROCK subfamily
consists of two isoforms, ROCK1 and ROCK2, which may be
functionally redundant in some systems, but exhibit
different tissue distributions. Both isoforms are
ubiquitously expressed in most tissues, but ROCK2 is
more prominent in brain and skeletal muscle while ROCK1
is more pronounced in the liver, testes, and kidney.
Studies in knockout mice result in different phenotypes,
suggesting that the two isoforms do not compensate for
each other during embryonic development.

with a dimer of regulatory (R) subunits. Activation is
achieved through the binding of the important second
messenger cAMP to the R subunits, which leads to the
dissociation of PKA into the R dimer and two active C

interacts with many different downstream targets. It
plays a role in the regulation of diverse processes such
as growth, development, memory, metabolism, gene

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

transduction pathways that regulate cell migration and
polarity, proliferation, differentiation, and apoptosis.
Also included in this subfamily are the PKC-like

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.

superfamily that includes the catalytic domains of RIO

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.

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

PKC-alpha is expressed in many tissues and is
associated with cell proliferation, apoptosis, and cell
motility. It plays a role in the signaling of the
growth factors PDGF, VEGF, EGF, and FGF. Abnormal
levels of PKC-alpha have been detected in many
transformed cell lines and several human tumors. In
addition, PKC-alpha is required for HER2 dependent
breast cancer invasion.

>gnl|CDD|173659 cd05122, PKc_STE, Catalytic domain of STE family Protein Kinases.
Protein Kinases (PKs), STE family, catalytic (c)
domain. PKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine or
tyrosine residues on protein substrates. The STE family
is part of a larger superfamily that includes the
catalytic domains of other protein serine/threonine
kinases (STKs), protein tyrosine kinases (PTKs), RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase (PI3K). This
family is composed of STKs, and some dual-specificity
PKs that phosphorylate both threonine and tyrosine
residues of target proteins. Most members are kinases
involved in mitogen-activated protein kinase (MAPK)
signaling cascades, acting as MAPK kinases (MAPKKs),
MAPK kinase kinases (MAPKKKs), or MAPK kinase kinase
kinases (MAP4Ks). The MAPK signaling pathways are
important mediators of cellular responses to
extracellular signals. The pathways involve a triple
kinase core cascade comprising of the MAPK, which is
phosphorylated and activated by a MAPKK, which itself
is phosphorylated and activated by a MAPKKK. Each MAPK
cascade is activated either by a small GTP-binding
protein or by an adaptor protein, which transmits the
signal either directly to a MAPKKK to start the triple
kinase core cascade or indirectly through a mediator
kinase, a MAP4K. Other STE family members include
p21-activated kinases (PAKs) and class III myosins,
among others. PAKs are Rho family GTPase-regulated
kinases that serve as important mediators in the
function of Cdc42 (cell division cycle 42) and Rac.
Class III myosins are motor proteins containing an
N-terminal kinase catalytic domain and a C-terminal
actin-binding domain, which can phosphorylate several
cytoskeletal proteins, conventional myosin regulatory
light chains, as well as autophosphorylate the
C-terminal motor domain. They play an important role in
maintaining the structural integrity of photoreceptor
cell microvilli.

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

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.

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.

(ASK1) and the mitogen-activated protein kinase (MAPK)
p38. It acts as a MAPK kinase kinase (MAPKKK) by
phosphorylating ASK1, resulting in the phosphorylation
of p38. SLK also plays a role in mediating actin
reorganization. It is part of a microtubule-associated
complex that is targeted at adhesion sites, and is
required in focal adhesion turnover and in regulating

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

Vertebrate members contain an N-terminal catalytic

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

activate the MAPK c-Jun N-terminal kinase (JNK).

is composed of Schizosaccharomyces pombe Nak1,
Saccharomyces cerevisiae Kic1p (kinase that interacts
with Cdc31p) and related proteins. Nak1 (also known as
N-rich kinase 1), 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. Kic1p is
required by budding yeast for cell integrity and
morphogenesis. Kic1p interacts with Cdc31p, the yeast

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.

Serine/Threonine Kinases (STKs), Mitogen-Activated
Protein Kinase (MAPK) subfamily, catalytic (c) domain.
STKs catalyze the transfer of the gamma-phosphoryl
group from ATP to serine/threonine residues on protein
substrates. The MAPK subfamily is part of a larger
superfamily that includes the catalytic domains of
other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. MAPKs serve as
important mediators of cellular responses to
extracellular signals. They control critical cellular
functions including differentiation, proliferation,
migration, and apoptosis. They are also implicated in
the pathogenesis of many diseases including multiple
types of cancer, stroke, diabetes, and chronic
inflammation. Typical MAPK pathways involve a triple
kinase core cascade comprising of the MAPK, which is
phosphorylated and activated by a MAPK kinase (MAP2K or
MKK), which itself is phosphorylated and activated by a
MAPK kinase kinase (MAP3K or MKKK). Each cascade is
activated either by a small GTP-binding protein or by
an adaptor protein, which transmits the signal either
directly to a MAP3K to start the triple kinase core
cascade or indirectly through a mediator kinase, a
MAP4K. There are three main typical MAPK subfamilies:
Extracellular signal-Regulated Kinase (ERK), c-Jun
N-terminal Kinase (JNK), and p38. Some MAPKs are
atypical in that they are not regulated by MAP2Ks.
These include MAPK4, MAPK6, NLK, and ERK7.

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

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

This PTKc family is part of a larger superfamily that

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.

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

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

inhibition by Gadd45beta and the subsequent suppression
of the JNK cascade.

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

MAP/ERK kinase (MEK) subfamily, catalytic (c) domain.
PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on
protein substrates. The MEK subfamily is part of a
larger superfamily that includes the catalytic domains
of other protein serine/threonine kinases, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. The mitogen-activated
protein (MAP) kinase signaling pathways are important
mediators of cellular responses to extracellular
signals. The pathways involve a triple kinase core
cascade comprising the MAP kinase (MAPK), which is
phosphorylated and activated by a MAPK kinase (MAPKK or
MKK), which itself is phosphorylated and activated by a
MAPK kinase kinase (MAPKKK or MKKK). MEK1 and MEK2 are
dual-specificity PKs that phosphorylate and activate
the downstream targets, ERK(extracellular
signal-regulated kinase) 1 and ERK2, on specific
threonine and tyrosine residues. The ERK cascade starts
with extracellular signals including growth factors,
hormones, and neurotransmitters, which act through
receptors and ion channels to initiate intracellular
signaling that leads to the activation at the MAPKKK
(Raf-1 or MOS) level, which leads to the transmission
of signals to MEK1/2, and finally to ERK1/2. The ERK
cascade plays an important role in cell proliferation,
differentiation, oncogenic transformation, and cell
cycle control, as well as in apoptosis and cell
survival under certain conditions. This cascade has
also been implicated in synaptic plasticity, migration,
morphological determination, and stress response
immunological reactions. Gain-of-function mutations in
genes encoding ERK cascade proteins, including MEK1/2,
cause cardiofaciocutaneous (CFC) syndrome, a condition
leading to multiple congenital anomalies and mental
retardation in patients.

orphan receptor tyr kinase (RTK) containing an
extracellular region with seven immunoglobulin domains,
a transmembrane segment, and an intracellular inactive

essential for neural development. Mouse embryos
containing a truncated CCK4 die perinatally and display
craniorachischisis, a severe form of neural tube defect.
The mechanism of action of the CCK4 pseudokinase is
still unknown. Other pseudokinases such as HER3 rely on
the activity of partner RTKs.

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.

receptor signaling. They are activated by
autophosphorylation upon cytokine-induced receptor
aggregation, and subsequently trigger downstream
signaling events such as the phosphorylation of signal
transducers and activators of transcription (STATs).
Jak1 is widely expressed in many tissues. Many cytokines
are dependent on Jak1 for signaling, including those
that use the shared receptor subunits common gamma chain
(IL-2, IL-4, IL-7, IL-9, IL-15, IL-21) and gp130 (IL-6,
IL-11, oncostatin M, G-CSF, and IFNs, among others). The
many varied interactions of Jak1 and its ubiquitous
expression suggest many biological roles. Jak1 is
important in neurological development, as well as in
lymphoid development and function. It also plays a role
in the pathophysiology of cardiac hypertrophy and heart
failure. A mutation in the ATP-binding site of Jak1 was
identified in a human uterine leiomyosarcoma cell line,
resulting in defective cytokine induction and antigen
presentation, thus allowing the tumor to evade the
immune system.

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.

PAK4 belongs to group II. Group II PAKs contain a PBD
(p21-binding domain) and a C-terminal catalytic domain,
but do not harbor an AID (autoinhibitory domain) or SH3
binding sites. 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
mammary tumors. PAK4 has also been implicated in viral
and bacterial infection pathways.

domain. PKB (also called Akt), a member of the AGC
kinase family, is a phosphatidylinositol 3'-kinase
(PI3K)-dependent Ser/Thr kinase which alters the
activity of the targeted protein. The name AGC is based
on the three proteins that it is most similar to
cAMP-dependent protein kinase 1 (PKA; also known as
PKAC), cGMP-dependent protein kinase (PKG; also known as
CGK1) and protein kinase C (PKC). Human Akt has three
isoforms derived for distinct genes: Akt1/PKBalpha,
Akt2/PKBbeta, and Akt3/PKBgamma. All Akts have an
N-terminal PH domain with an activating Thr
phosphorylation site, a kinase domain, and a short
C-terminal regulatory tail with an activating Ser
phosphorylation site. The PH domain recruits Akt to the
plasma membrane by binding to phosphoinositides
(PtdIns-3,4-P2) and is required for activation. The
phosphorylation of Akt at its Thr and Ser
phosphorylation sites leads to increased Akt activity
toward forkhead transcription factors, the mammalian
target of rapamycin (mTOR), and the
Bcl-xL/Bcl-2-associated death promoter (BAD), all of
which possess a consensus motif R-X-R-XX-ST-B (X = amino
acid, B = bulky hydrophobic residue) for Akt
phosphorylation. PH domains have diverse functions, but
in general are involved in targeting proteins to the
appropriate cellular location or in the interaction with
a binding partner. They share little sequence
conservation, but all have a common fold, which is
electrostatically polarized. Less than 10% of PH domains
bind phosphoinositide phosphates (PIPs) with high
affinity and specificity. PH domains are distinguished
from other PIP-binding domains by their specific
high-affinity binding to PIPs with two vicinal phosphate
groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3
which results in targeting some PH domain proteins to
the plasma membrane. A few display strong specificity in
lipid binding. Any specificity is usually determined by
loop regions or insertions in the N-terminus of the
domain, which are not conserved across all PH domains.
PH domains are found in cellular signaling proteins such
as serine/threonine kinase, tyrosine kinases, regulators
of G-proteins, endocytotic GTPases, adaptors, as well as
cytoskeletal associated molecules and in lipid
associated enzymes.

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

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,

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

T-cells express Itk, Txk, and Tec. Collectively, Tec
kinases are expressed in a variety of myeloid cells
such as mast cells, platelets, macrophages, and
dendritic cells. Each Tec kinase shows a distinct
cell-type pattern of expression. The function of Tec
kinases in lymphoid cells have been studied
extensively. They play important roles in the
development, differentiation, maturation, regulation,
survival, and function of B-cells and T-cells.
Mutations in Btk cause the severe B-cell

Tyrosine Kinase (PTK) family; Tyrosine kinase expressed
in hepatocellular carcinoma (Tec) and Resting lymphocyte
kinase (Rlk); 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. Tec and
Rlk (also named Txk) are members of the Tec subfamily of
proteins, which are cytoplasmic (or nonreceptor) tyr
kinases with similarity to Src kinases in that they
contain Src homology protein interaction domains (SH3,
SH2) N-terminal to the catalytic tyr kinase domain.
Unlike Src kinases, most Tec subfamily members (except
Rlk) also contain an N-terminal pleckstrin homology (PH)
domain, which binds the products of PI3K and allows
membrane recruitment and activation. Instead of PH, Rlk
contains an N-terminal cysteine-rich region. In addition
to PH, Tec also contains the Tec homology (TH) domain
with proline-rich and zinc-binding regions. Tec kinases
are expressed mainly by haematopoietic cells. Tec is
more widely-expressed than other Tec subfamily kinases.
It is found in endothelial cells, both B- and T-cells,
and a variety of myeloid cells including mast cells,
erythroid cells, platelets, macrophages and neutrophils.
Rlk is expressed in T-cells and mast cell lines. Tec and
Rlk are both key components of T-cell receptor (TCR)
signaling. They are important in TCR-stimulated
proliferation, IL-2 production and phopholipase C-gamma1
activation.

Serine/Threonine Kinases, Oxidative stress response
kinase and Ste20-related proline alanine-rich kinase.
Serine/threonine kinases (STKs), oxidative stress
response kinase (OSR1) and Ste20-related proline
alanine-rich kinase (SPAK) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The OSR1 and SPAK
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. SPAK is also referred to as
STK39 or PASK (proline-alanine-rich STE20-related
kinase). OSR1 and SPAK regulate the activity of
cation-chloride cotransporters through direct
interaction and phosphorylation. They are also
implicated in cytoskeletal rearrangement, cell
differentiation, transformation and proliferation. OSR1
and SPAK contain a conserved C-terminal (CCT) domain,
which recognizes a unique motif ([RK]FX[VI]) present in
their activating kinases (WNK1/WNK4) and their
substrates.

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

(STKs), Nemo-Like Kinase (NLK) subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine

phosphoinositide 3-kinase. Mitogen-activated protein
kinases (MAPKs) are important mediators of cellular
responses to extracellular signals. NLK is an atypical
MAPK that is not regulated by a MAPK kinase. It
functions downstream of the MAPK kinase kinase Tak1,
which also plays a role in activating the JNK and p38
MAPKs. The Tak1/NLK pathways are regulated by Wnts, a
family of secreted proteins that is critical in the
control of asymmetric division and cell polarity. NLK
can phosphorylate transcription factors from the
TCF/LEF family, inhibiting their ability to activate
the transcription of target genes. In prostate cancer
cells, NLK is involved in regulating androgen
receptor-mediated transcription and its expression is
altered during cancer progression.
