>gnl|CDD|173734 cd07830, STKc_MAK_like, Catalytic domain of Male germ
cell-Associated Kinase-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Male germ
cell-Associated Kinase (MAK)-like subfamily, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAK-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 human MAK and
MAK-related kinase (MRK), Saccharomyces cerevisiae
Ime2p, Schizosaccharomyces pombe Mei4-dependent protein
3 (Mde3) and Pit1, Caenorhabditis elegans dyf-5,
Arabidopsis thaliana MHK, and similar proteins. These
proteins play important roles during meiosis. MAK is
highly expressed in testicular cells specifically in the
meiotic phase, but is not essential for spermatogenesis
and fertility. It functions as a coactivator of the
androgen receptor in prostate cells. MRK, also called
Intestinal Cell Kinase (ICK), is expressed ubiquitously,
with highest expression in the ovary and uterus. A
missense mutation in MRK causes
endocrine-cerebro-osteodysplasia (ECO), suggesting that
this protein plays an important role in the development
of many organs. MAK and MRK may be involved in
regulating cell cycle and cell fate. Ime2p is a
meiosis-specific kinase that is important during meiotic
initiation and during the later stages of meiosis. Mde3
functions downstream of the transcription factor Mei-4
which is essential for meiotic prophase I.

>gnl|CDD|173623 cd00180, PKc, Catalytic domain of Protein Kinases. Protein Kinases
(PKs), catalytic (c) domain. PKs catalyze the transfer
of the gamma-phosphoryl group from ATP to
serine/threonine or tyrosine residues on protein
substrates. The PK family is part of a larger
superfamily that includes the catalytic domains of RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, phosphoinositide 3-kinase (PI3K), and
actin-fragmin kinase. PKs make up a large family of
serine/threonine kinases, protein tyrosine kinases
(PTKs), and dual-specificity PKs that phosphorylate both
serine/threonine and tyrosine residues of target
proteins. Majority of protein phosphorylation, about
95%, occurs on serine residues while only 1% occurs on
tyrosine residues. Protein phosphorylation is a
mechanism by which a wide variety of cellular proteins,
such as enzymes and membrane channels, are reversibly
regulated in response to certain stimuli. PKs often
function as components of signal transduction pathways
in which one kinase activates a second kinase, which in
turn, may act on other kinases; this sequential action
transmits a signal from the cell surface to target
proteins, which results in cellular responses. The PK
family is one of the largest known protein families with
more than 100 homologous yeast enzymes and 550 human
proteins. A fraction of PK family members are
pseudokinases that lack crucial residues for catalytic
activity. The mutiplicity of kinases allows for specific
regulation according to substrate, tissue distribution,
and cellular localization. PKs regulate many cellular
processes including proliferation, division,
differentiation, motility, survival, metabolism,
cell-cycle progression, cytoskeletal rearrangement,
immunity, and neuronal functions. Many kinases are
implicated in the development of various human diseases
including different types of cancer.

>gnl|CDD|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.

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.

hyperosmotic stress. Activated Hog1 accumulates in the
nucleus and regulates stress-induced transcription. The
HOG pathway is mediated by two transmembrane
osmosensors, Sln1 and Sho1.

(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.

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

substrates. The CDK4 subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,

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.

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

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.

PKs catalyze the transfer of the gamma-phosphoryl group

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.

Serine/threonine kinases (STKs), (Cdc7)-like subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The Cdc7-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. Members of this subfamily include
Schizosaccharomyces pombe Cdc7, Saccharomyces cerevisiae
Cdc15, Arabidopsis thaliana mitogen-activated protein
kinase (MAPK) kinase kinase (MAPKKK) epsilon, and
related proteins. 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 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 development in the plasma membrane.

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.

Kinases, Mitogen-Activated Protein Kinases 4 and 6.
Serine/Threonine Kinases (STKs), Mitogen-Activated
Protein Kinase 4 (MAPK4) and MAPK6 subfamily, catalytic
(c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAPK4/6 subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. MAPKs are
important mediators of cellular responses to
extracellular signals. MAPK4 is also called ERK4 or
p63MAPK, while 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 exclusion from the nucleus. The MAPK6/MK5
and MAPK4/MK5 pathways may play critical roles in
embryonic and post-natal development.

including Arabidopsis thaliana MEKK1 and MAPKKK3. MEKK1
is a MAPKKK 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. Arabidopsis thaliana
MEKK1 activates MPK4, a MAPK that regulates systemic

of STKs that are regulated by their cognate cyclins.
Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK6
is regulated by D-type cyclins and INK4 inhibitors. It
is active towards the retinoblastoma (pRb) protein,
implicating it to function in regulating the early G1
phase of the cell cycle. It is expressed ubiquitously
and is localized in the cytoplasm. It is also present in
the ruffling edge of spreading fibroblasts and may play
a role in cell spreading. It binds to the p21 inhibitor
without any effect on its own activity and it is
overexpressed in squamous cell carcinomas and
neuroblastomas. CDK6 has also been shown to inhibit cell
differentiation in many cell types.

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.

PAK3 belongs to group I. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). PAK3 is
highly expressed in the brain. It is implicated in
neuronal plasticity, synapse formation, dendritic spine
morphogenesis, cell cycle progression, neuronal
migration, and apoptosis. Inactivating mutations in the
PAK3 gene cause X-linked non-syndromic mental
retardation, the severity of which depends on the site
of the mutation.

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

increase cell invasion and breast cancer progression. In
Xenopus, p38gamma is critical in the meiotic maturation
of oocytes.

(PAK) 1, 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.
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.

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

four isoforms of p38, 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 main isoform involved in regulating the
differentiation and apoptosis of keratinocytes.

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 or MAP2K), which itself is phosphorylated
and activated by a MAPK kinase kinase (MAPKKK or MKKK or
MAP3K). MAPKKs are dual-specificity PKs that
phosphorylate their downstream targets, MAPKs, at
specific threonine and tyrosine residues. There are
three MAPK subfamilies: extracellular signal-regulated
kinase (ERK), c-Jun N-terminal kinase (JNK), and p38. In
mammalian cells, there are seven MAPKKs (named MKK1-7)
and 20 MAPKKKs. Each MAPK subfamily can be activated by
at least two cognate MAPKKs and by multiple MAPKKKs.

opposing effects by positive and negative regulation,
respectively, in similar conditions.

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.

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

protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PAKs are Rho family GTPase-regulated kinases
that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs are
implicated in the regulation of many cellular processes
including growth factor receptor-mediated proliferation,
cell polarity, cell motility, cell death and survival,
and actin cytoskeleton organization. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
Group I PAKs, also called conventional PAKs, include
PAK1, PAK2, and PAK3. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). They interact
with the SH3 domain containing proteins Nck, Grb2 and
PIX. Binding of group I PAKs to activated GTPases leads
to conformational changes that destabilize the AID,
allowing autophosphorylation and full activation of the
kinase domain. Known group I PAK substrates include
MLCK, Bad, Raf, MEK1, LIMK, Merlin, Vimentin, Myc,
Stat5a, and Aurora A, among others.

(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. JNK1
specifically binds with JAMP (JNK1-associated membrane
protein), which regulates the duration of JNK1 activity
in response to stimuli. Specific JNK1 substrates include
Itch and SG10, which are implicated in Th2 responses and
airway inflammation, and microtubule dynamics and
axodendritic length, respectively. Mice deficient in
Jnk1 are protected against arthritis, obesity, type 2
diabetes, cardiac cell death, and non-alcoholic liver
disease, suggesting that JNK1 may play roles in the
pathogenesis of these diseases.

>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.

Serine/threonine kinases (STKs), Apoptosis
signal-regulating kinase (ASK) subfamily, catalytic (c)

gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The ASK subfamily is
part of a larger superfamily that includes the catalytic

are mitogen-activated protein kinase (MAPK) kinase
kinases (MAPKKKs or MKKKs or MAP3Ks) and include ASK1,
ASK2, and MAPKKK15. 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. ASK1 (also called
MAPKKK5) functions in the c-Jun N-terminal kinase (JNK)
and p38 MAPK signaling pathways by directly activating
their respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. It
plays important roles in cytokine and stress responses,
as well as in reactive oxygen species (ROS)-mediated
cellular responses. ASK1 is implicated in various
diseases mediated by oxidative stress including
inschemic heart disease, hypertension, vessel injury,
brain ischemia, Fanconi anemia, asthma, and pulmonary
edema, among others. ASK2 (also called MAPKKK6)
functions only in a heteromeric complex with ASK1, and
can activate ASK1 by direct phosphorylation. The
function of MAPKKK15 is still unknown.

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.

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.

The PAK subfamily is part of a larger superfamily that

that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
Group II PAKs, also called non-conventional PAKs,
include PAK4, PAK5, and PAK6. Group II PAKs contain PBD
(p21-binding domain) and catalytic domains, but lack
other motifs found in group I PAKs, such as an AID
(autoinhibitory domain) and SH3 binding sites. Since
group II PAKs do not contain an obvious AID, they may be
regulated differently from group I PAKs. While group I
PAKs interact with the SH3 containing proteins Nck, Grb2
and PIX, no such binding has been demonstrated for group
II PAKs. Some known substrates of group II PAKs are also
substrates of group I PAKs such as Raf, BAD, LIMK and
GEFH1. Unique group II substrates include MARK/Par-1 and
PDZ-RhoGEF. Group II PAKs play important roles in
filopodia formation, neuron extension, cytoskeletal
organization, and cell survival.

similar fungal proteins. They contain a central
catalytic domain, which contains an insert relative to
MAST kinases. In addition, Rim15 contains a C-terminal
signal receiver (REC) domain while cek1 contains an
N-terminal PAS domain. Rim15 (or Rim15p) functions as a

MEKK3 subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside

(MAPK) kinase kinase (MAPKKK or MKKK or MAP3K), that
phosphorylates and activates the MAPK kinase MEK5 (or
MKK5), which in turn phosphorylates and 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. In addition, MEKK3 is
involved in interleukin-1 receptor and Toll-like
receptor 4 signaling. It is also a specific regulator of
the proinflammatory cytokines IL-6 and GM-CSF in some
immune cells. MEKK3 also regulates calcineurin, which
plays a critical role in T cell activation, apoptosis,
skeletal myocyte differentiation, and cardiac
hypertrophy.

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. 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.

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.

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.

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. CDC2L6 is also called CDK8-like and was
previously referred to as CDK11. However, this is a
confusing nomenclature as CDC2L6 is distinct from
CDC2L1, which is represented by the two protein products
from its gene, called CDK11(p110) and CDK11(p58), as
well as the caspase-processed CDK11(p46). CDK11(p110),
CDK11(p58), and CDK11(p46)do not belong to this
subfamily. CDC2L6 is an associated protein of Mediator,
a multiprotein complex that provides a platform to
connect transcriptional and chromatin regulators and
cofactors, in order to activate and mediate RNA
polymerase II transcription. CDC2L6 is localized mainly
in the nucleus amd exerts an opposing effect to CDK8 in
VP16-dependent transcriptional activation by being a
negative regulator.

of neurofibrillary tangles (NFTs). In human glioma
cells, PCTAIRE-3 induces cell cycle arrest and cell

Serine/threonine kinases (STKs), p21-activated kinase
(PAK) 6, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to

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

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.
PAK6 belongs to group II. Group II PAKs contain a PBD
(p21-binding domain) and a C-terminal catalytic domain,
but do not harbor an AID (autoinhibitory domain) or SH3
binding sites. PAK6 may play a role in stress responses
through its activation by the mitogen-activated protein
kinase (MAPK) p38 and MAPK kinase 6 (MKK6) pathway. PAK6
is highly expressed in the brain. It is not required for
viability, but together with PAK5, it is required for
normal levels of locomotion and activity, and for
learning and memory. Increased expression of PAK6 is
found in primary and metastatic prostate cancer. PAK6
may play a role in the regulation of motility.

family; Fyn and Yrk kinases; 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. Fyn and
Yrk are members of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases contain an N-terminal SH4 domain with a
myristoylation site, followed by SH3 and SH2 domains, a
tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr. They are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the
C-terminal tyr by Csk (C-terminal Src Kinase). Src
proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Fyn, together with Lck, plays a
critical role in T-cell signal transduction by
phosphorylating ITAM (immunoreceptor tyr activation
motif) sequences on T-cell receptors, ultimately leading
to the proliferation and differentiation of T-cells. In
addition, Fyn is involved in the myelination of neurons,
and is implicated in Alzheimer's and Parkinson's
diseases. Yrk has been detected only in chickens. It is
primarily found in neuronal and epithelial cells and in
macrophages. It may play a role in inflammation and in
response to injury.

Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK8
can act as a negative or positive regulator of
transcription, depending on the scenario. Together with
its regulator, cyclin C, it reversibly associates with
the multi-subunit core Mediator complex, a cofactor that
is involved in regulating RNA polymerase II (RNAP
II)-dependent transcription. CDK8 phosphorylates cyclin
H, a subunit of the general transcription factor TFIIH,
which results in the inhibition of TFIIH-dependent
phosphorylation of the C-terminal domain (CTD) of RNAP
II, facilitating the inhibition of transcription. It has
also been shown to promote transcription by a mechanism
that is likely to involve RNAP II phosphorylation. CDK8
also functions as a stimulus-specific positive
coregulator of p53 transcriptional responses.

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).

Tyrosine Kinases. Protein Tyrosine Kinase (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.

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).

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

Tyrosine Kinase, Janus kinase 1. Protein Tyrosine
Kinase (PTK) family; Janus kinase 1 (Jak1); catalytic
(c) domain (repeat 2). 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. Jak1 is a member of the
Janus kinase (Jak) subfamily of proteins, which are
cytoplasmic (or nonreceptor) tyr kinases containing an
N-terminal FERM domain, followed by a Src homology 2
(SH2) domain, a pseudokinase domain, and a C-terminal
tyr kinase domain. Jaks are crucial for cytokine
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.

are plant phototropins and predominantly uncharacterized
fungal STKs whose catalytic domains resemble the
phototropin kinase domain. One protein from Neurospora
crassa is called nrc-2. Phototropins are blue-light
receptors that control responses such as phototropism,
stromatal opening, and chloroplast movement in order to
optimize the photosynthetic efficiency of plants. They
are light-activated STKs that contain an N-terminal
photosensory domain and a C-terminal catalytic domain.
The N-terminal domain contains two LOV (Light, Oxygen or
Voltage) domains that binds FMN. Photoexcitation of the
LOV domains results in autophosphorylation at multiple
sites and activation of the catalytic domain. Neurospora
crassa nrc-2 plays a role in growth and development by
controlling entry into the conidiation program.

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.
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.

gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. Lyn is a member of the
Src subfamily of proteins, which are cytoplasmic (or
non-receptor) tyr kinases. Src kinases contain an
N-terminal SH4 domain with a myristoylation site,
followed by SH3 and SH2 domains, a tyr kinase domain,
and a regulatory C-terminal region containing a
conserved tyr. They are activated by autophosphorylation
at the tyr kinase domain, but are negatively regulated
by phosphorylation at the C-terminal tyr by Csk
(C-terminal Src Kinase). Src proteins are involved in
signaling pathways that regulate cytokine and growth
factor responses, cytoskeleton dynamics, cell
proliferation, survival, and differentiation. Lyn is
expressed in B lymphocytes and myeloid cells. It
exhibits both positive and negative regulatory roles in
B cell receptor (BCR) signaling. Lyn, as well as Fyn and
Blk, promotes B cell activation by phosphorylating ITAMs
(immunoreceptor tyr activation motifs) in CD19 and in Ig
components of BCR. It negatively regulates signaling by
its unique ability to phosphorylate ITIMs
(immunoreceptor tyr inhibition motifs) in cell surface
receptors like CD22 and CD5. Lyn also plays an important
role in G-CSF receptor signaling by phosphorylating a
variety of adaptor molecules.

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

roles in the cardiovascular, immune, respiratory,
skeletal, and nervous systems.

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). MKK5, also referred to as MEK5, is a

target, extracellular signal-regulated kinase 5 (ERK5),
on specific threonine and tyrosine residues. MKK5 is
activated by MEKK2 and MEKK3 in response to mitogenic
and stress stimuli. The ERK5 cascade promotes cell
proliferation, differentiation, neuronal survival, and
neuroprotection. This cascade plays an essential role in
heart development. Mice deficient in either ERK5 or MKK5
die around embryonic day 10 due to cardiovascular
defects including underdevelopment of the myocardium. In
addition, MKK5 is associated with metastasis and
unfavorable prognosis in prostate cancer.

protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PKCs are classified into three groups
(classical, atypical, and novel) depending on their mode
of activation and the structural characteristics of
their regulatory domain. nPKCs are calcium-independent,
but require DAG (1,2-diacylglycerol) and
phosphatidylserine (PS) for activity. There are four
nPKC isoforms, delta, epsilon, eta, and theta. PKC-theta
is selectively expressed in T-cells and plays an
important and non-redundant role in several aspects of
T-cell biology. Although T-cells also express other PKC
isoforms, PKC-theta is unique in that upon antigen
stimulation, it is translocated to the plasma membrane
at the immunological synapse, where it mediates signals
essential for T-cell activation. It is essential for
TCR-induced proliferation, cytokine production, T-cell
survival, and the differentiation and effector function
of T-helper (Th) cells, particularly Th2 and Th17.
PKC-theta is being developed as a therapeutic target for
Th2-mediated allergic inflammation and Th17-mediated
autoimmune diseases.

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

3-kinase. MSKs contain an N-terminal kinase domain (NTD)
from the AGC family and a C-terminal kinase domain (CTD)
from the CAMK family, similar to 90 kDa ribosomal
protein S6 kinases (RSKs). MSKs are activated by two
major signaling cascades, the Ras-MAPK and p38 stress
kinase pathways, which trigger phosphorylation in the
activation loop (A-loop) of the CTD of MSK. The active
CTD phosphorylates the hydrophobic motif (HM) of NTD,
which facilitates the phosphorylation of the A-loop and
activates the NTD, which in turn phosphorylates
downstream targets. MSK1 plays a role in the regulation
of translational control and transcriptional activation.
It phosphorylates the transcription factors, CREB and
NFkappaB. It also phosphorylates the nucleosomal
proteins H3 and HMG-14. Increased phosphorylation of
MEK1 is associated with the development of cerebral
ischemic/hypoxic preconditioning.

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 the MAPKKs Pek1/Skh1 from
Schizosaccharomyces pombe and MKK2 from Saccharomyces
cerevisiae, and related proteins. Both fission yeast
Pek1 and baker's yeast MKK2 are components of the cell
integrity MAPK pathway. In fission yeast, Pek1
phosphorylates and activates the MAPK Pmk1/Spm1 and is
regulated by the MAPKKK Mkh1. In baker's yeast, the
pathway involves the MAPK Slt2, the MAPKKs MKK1 and
MKK2, and the MAPKKK Bck1. The cell integrity MAPK
cascade is activated by multiple stress conditions, and
is essential in cell wall construction, morphogenesis,
cytokinesis, and ion homeostasis.

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.

myosins may play an important role in maintaining the
structural integrity of photoreceptor cell microvilli.
In photoreceptor cells, they may also function as cargo
carriers during light-dependent translocation of
proteins such as transducin and arrestin. Class IIIA
myosin is highly expressed in retina and in inner ear
hair cells. It is localized to the distal ends of
actin-bundled structures. Mutations in human myosin IIIA
are responsible for progressive nonsyndromic hearing
loss. Human myosin IIIA possesses ATPase and kinase
activities, and the ability to move actin filaments in a
motility assay. It may function as a cellular
transporter capable of moving along actin bundles in
sensory cells.

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. Lck is expressed in T-cells and natural
killer (NK) cells. It plays a critical role in T-cell
maturation, activation, and T-cell receptor (TCR)
signaling. Lck phosphorylates ITAM (immunoreceptor tyr
activation motif) sequences on several subunits of TCRs,
leading to the activation of different second messenger
cascades. Phosphorylated ITAMs serve as binding sites
for other signaling factor such as Syk and ZAP-70,
leading to their activation and propagation of
downstream events. In addition, Lck regulates
drug-induced apoptosis by interfering with the
mitochondrial death pathway. The apototic role of Lck is
independent of its primary function in T-cell signaling.
Blk is expressed specifically in B-cells. It is involved
in pre-BCR (B-cell receptor) signaling.

Kinase, HER3. Protein Tyrosine Kinase (PTK) family;
HER3 (ErbB3); pseudokinase domain. The PTKc (catalytic
domain) family to which this subfamily belongs, 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. HER3 is a
member of the EGFR (HER, ErbB) subfamily of proteins,
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. HER3 binds the neuregulin ligands, NRG1 and
NRG2. HER3 contains an impaired tyr kinase domain and
relies on its heterodimerization partners for activity
following ligand binding. The HER2-HER3 heterodimer
constitutes a high affinity co-receptor capable of
potent mitogenic signaling. HER3 participates in a
signaling pathway involved in the proliferation,
survival, adhesion, and motility of tumor cells.

myosin-like Protein Serine/Threonine Kinases.
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.

DDR subfamily members 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. DDRs regulate cell
adhesion, proliferation, and extracellular matrix
remodeling. They have been linked to a variety of human
cancers including breast, colon, ovarian, brain, and
lung. There is no evidence showing that DDRs act as
transforming oncogenes. They are more likely to play a
role in the regulation of tumor growth and metastasis.

(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.

proteins containing an N-terminal kinase catalytic
domain and a C-terminal actin-binding domain. Class III
myosins may play an important role in maintaining the
structural integrity of photoreceptor cell microvilli.
They may also function as cargo carriers during
light-dependent translocation, in photoreceptor cells,
of proteins such as transducin and arrestin. Class IIIB
myosin is expressed highly in retina. It is also present
in the brain and testis. The human class IIIB myosin
gene maps to a region that overlaps the locus for
Bardet-Biedl syndrome, which is characterized by
dysmorphic extremities, retinal dystrophy, obesity, male
hypogenitalism, and renal abnormalities.

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

structural characteristics of their regulatory domain.
PKCs undergo three phosphorylations in order to take
mature forms. In addition, cPKCs depend on calcium, DAG
(1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. There are four
cPKC isoforms, named alpha, betaI, betaII, and gamma.
The PKC beta isoforms (I and II), generated by
alternative splicing of a single gene, are
preferentially activated by hyperglycemia-induced DAG in
retinal tissues. This is implicated in diabetic
microangiopathy such as ischemia, neovascularization,
and abnormal vasodilator function. PKC-beta also plays
an important role in VEGF signaling. In addition,
glucose regulates proliferation in retinal endothelial
cells via PKC-betaI. PKC-beta is also being explored as

Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. GRK4 has a limited tissue distribution. It
is mainly found in the testis, but is also present in
the cerebellum and kidney. It is expressed as multiple
splice variants with different domain architectures. It
is post-translationally palmitoylated and localized in
the membrane. GRK4 polymorphisms are associated with
hypertension and salt sensitivity, as they cause
hyperphosphorylation, desensitization, and
internalization of the dopamine 1 (D1) receptor while
increasing the expression of the angiotensin II type 1
receptor. GRK4 plays a crucial role in the D1 receptor
regulation of sodium excretion and blood pressure.

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

Factor Receptor-like Protein Tyrosine Kinases. Protein
Tyrosine Kinase (PTK) family; Epidermal Growth Factor
Receptor (EGFR) subfamily; catalytic (c) domain. EGFR
(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.

Kinase, HER2. Protein Tyrosine Kinase (PTK) family;
HER2 (ErbB2, HER2/neu); 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. HER2 is a
member of the EGFR (HER, ErbB) subfamily of proteins,
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.

N-terminal kinase domain (NTD) from the AGC family and a
C-terminal kinase domain (CTD) from the CAMK family,
similar to 90 kDa ribosomal protein S6 kinases (RSKs).
MSKs are activated by two major signaling cascades, the
Ras-MAPK and p38 stress kinase pathways, in response to
various stimuli such as growth factors, hormones,
neurotransmitters, cellular stress, and pro-inflammatory
cytokines. This triggers phosphorylation in the
activation loop (A-loop) of the CTD of MSK. The active
CTD phosphorylates the hydrophobic motif (HM) in the
C-terminal extension of NTD, which facilitates the
phosphorylation of the A-loop and activates the NTD,
which in turn phosphorylates downstream targets. MSKs
are predominantly nuclear proteins. They are widely
expressed in many tissues including heart, brain, lung,
liver, kidney, and pancreas. There are two isoforms of
MSK, called MSK1 and MSK2.

Protein Tyrosine Kinase (PTK) family; Janus kinase 2
(Jak2) and Jak3; catalytic (c) domain (repeat 2). 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. Jak2 and
Jak3 are members of the Janus kinase (Jak) subfamily of
proteins, which are cytoplasmic (or nonreceptor) tyr
kinases containing an N-terminal FERM domain, followed
by a Src homology 2 (SH2) domain, a pseudokinase domain,
and a C-terminal catalytic tyr kinase domain. Jaks are
crucial for cytokine 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). Jak2 is widely expressed in many tissues while
Jak3 is expressed only in hematopoietic cells. Jak2 is
essential for the signaling of hormone-like cytokines
such as growth hormone, erythropoietin, thrombopoietin,
and prolactin, as well as some IFNs and cytokines that
signal through the IL-3 and gp130 receptors. Jak3 binds
the shared receptor subunit common gamma chain and thus,
is essential in the signaling of cytokines that use it
such as IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21.
Disruption of Jak2 in mice results in an embryonic
lethal phenotype with multiple defects including
erythropoietic and cardiac abnormalities. It is the only
Jak gene that results in a lethal phenotype when
disrupted in mice. A mutation in the pseudokinase domain
of Jak2, V617F, is present in many myeloproliferative
diseases, including almost all patients with
polycythemia vera, and 50% of patients with essential
thrombocytosis and myelofibrosis. Jak3 is important in
lymphoid development and myeloid cell differentiation.
Inactivating mutations in Jak3 have been reported in
humans with severe combined immunodeficiency (SCID).

Phosphorylated GPCRs bind to arrestins, which prevents
further G protein signaling despite the presence of
activating ligand. There are seven types of GRKs, named
GRK1 to GRK7. GRK6 is widely expressed in many tissues.
t is expressed as multiple splice variants with
different domain architectures. It is
post-translationally palmitoylated and localized in the

addiction and Parkinson's disease. GRK6-deficient mice
exhibit altered dopamine receptor regulation, decreased
lymphocyte chemotaxis, and increased acute inflammation
and neutrophil chemotaxis.

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

phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. EGFR
(HER1, ErbB1) is a member of the EGFR (HER, ErbB)
subfamily of proteins, 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. Ligands for EGFR include EGF, heparin binding
EGF-like growth factor (HBEGF), epiregulin,
amphiregulin, TGFalpha, and betacellulin. Upon ligand
binding, EGFR can form homo- or heterodimers with other
EGFR subfamily members. The EGFR signaling pathway is
one of the most important pathways regulating cell
proliferation, differentiation, survival, and growth.
Overexpression and mutation in the kinase domain of EGFR
have been implicated in the development and progression
of a variety of cancers. A number of monoclonal
antibodies and small molecule inhibitors have been
developed that target EGFR, including the antibodies
Cetuximab and Panitumumab, which are used in combination
with other therapies for the treatment of colorectal
cancer and non-small cell lung carcinoma (NSCLC). The
small molecule inhibitors Gefitinib (Iressa) and
Erlotinib (Tarceva), already used for NSCLC, are
undergoing clinical trials for other types of cancer
including gastrointestinal, breast, head and neck, and
bladder.

intermediate dismutates yielding riboflavin and
5-amino-6-ribitylamino- 2,4(1H,3H)-pyrimidinedione, in a
reaction catalyzed by riboflavin synthase (RS); RS
belongs to a different family of the
Lumazine-synthase-like superfamily. Riboflavin is the
precursor of flavin mononucleotide (FMN) and flavin
adenine dinucleotide (FAD) which are essential cofactors
for the catalysis of a wide range of redox reactions.
These cofactors are also involved in many other
processes involving DNA repair, circadian time-keeping,
light sensing, and bioluminescence. Riboflavin is
biosynthesized in plants, fungi and certain
microorganisms; as animals lack the necessary enzymes to
produce this vitamin, they acquire it from dietary
sources. Type II LSs are distinct from type-I LS not
only in protein sequence, but in that they exhibit
different quaternary assemblies; type-II LSs form
decamers (dimers of pentamers). The pathogen Brucella
spp. have both a type-I LS and a type-II LS called RibH1
and RibH2, respectively. RibH1/type-I LS appears to be a
functional LS in Brucella spp., whereas RibH2/type-II LS
has much lower catalytic activity as LS and may be
regulated by a riboswitch that senses FMN, suggesting
that the type-II LSs may have evolved into very poor
catalysts or, that they may harbor a new, as-yet-unknown
function.

Kinase-like Protein Tyrosine Kinases. Protein Tyrosine
Kinase (PTK) family; Spleen Tyrosine Kinase (Syk)
subfamily; catalytic (c) domain. The Syk subfamily is
composed of Syk, ZAP-70, Shark, 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. Syk
subfamily kinases are cytoplasmic (or nonreceptor) tyr
kinases containing two Src homology 2 (SH2) domains
N-terminal to the catalytic tyr kinase domain. They are
involved in the signaling downstream of activated
receptors (including B-cell, T-cell, and Fc receptors)
that contain ITAMs (immunoreceptor tyr activation
motifs), leading to processes such as cell
proliferation, differentiation, survival, adhesion,
migration, and phagocytosis. Syk is important in B-cell
receptor (BCR) signaling, while Zap-70 is primarily
expressed in T-cells and NK cells, and is a crucial
component in T-cell receptor (TCR) signaling. Syk also
plays a central role in Fc receptor-mediated
phagocytosis in the adaptive immune system. Shark is
exclusively expressed in ectodermally derived epithelia,
and is localized preferentially to the apical surface of
the epithelial cells, it may play a role in a signaling
pathway for epithelial cell polarity.

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 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.

Protein Tyrosine Kinase (PTK) family; Receptor tyrosine
kinase-like Orphan Receptor (Ror) subfamily; catalytic
(c) domain. The Ror subfamily consists of Ror1, Ror2,
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. 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. 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.

The nPKC 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. PKCs are classified into three groups
(classical, atypical, and novel) depending on their mode
of activation and the structural characteristics of
their regulatory domain. nPKCs are calcium-independent,
but require DAG (1,2-diacylglycerol) and
phosphatidylserine (PS) for activity. There are four
nPKC isoforms, delta, epsilon, eta, and theta.
PKC-epsilon has been shown to behave as an oncoprotein.
Its overexpression contributes to neoplastic
transformation depending on the cell type. It
contributes to oncogenesis by inducing disordered cell
growth and inhibiting cell death. It also plays a role
in tumor invasion and metastasis. PKC-epsilon has also
been found to confer cardioprotection against ischemia
and reperfusion-mediated damage. Other cellular
functions include the regulation of gene expression,
cell adhesion, and cell motility.

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

proliferation, survival, and differentiation, and
consequently, in cancer development and progression.

The RIO catalytic domain is truncated compared to the
catalytic domains of typical PKs, with deletions of the
loops responsible for substrate binding. RIO1 is present
in archaea, bacteria and eukaryotes. In addition, RIO3
is present in multicellular eukaryotes. RIO1 is
essential for survival and is required for 18S rRNA
processing, proper cell cycle progression and chromosome
maintenance. The biological substrates for RIO1 are
unknown. The function of RIO3 is also unknown.

family; Csk homologous kinase (Chk); 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. 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. Chk is also referred to
as megakaryocyte-associated tyrosine kinase (Matk). To
inhibit Src kinases, Chk is translocated to the membrane
via binding to specific transmembrane proteins,
G-proteins, or adaptor proteins near the membrane. Chk
inhibit Src kinases using a noncatalytic mechanism by
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.

classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
structural characteristics of their regulatory domain.
aPKCs only require phosphatidylserine (PS) for
activation. There are two aPKC isoforms, zeta and iota.
PKC-zeta plays a critical role in activating the glucose
transport response. It is activated by glucose, insulin,
and exercise through diverse pathways. PKC-zeta also
plays a central role in maintaining cell polarity in
yeast and mammalian cells. In addition, it affects actin
remodeling in muscle cells.

associated with centrosomes throughout the cell cycle.
It is involved in the formation of primary cilium and in
the maintenance of centrosomes. It cycles through the
nucleus and may be capable of relaying signals between
the cilium and the nucleus. Nek1 is implicated in the
development of polycystic kidney disease, which is
characterized by benign polycystic tumors formed by
abnormal overgrowth of renal epithelial cells. It
appears also to be involved in DNA damage response, and
may be important for both correct DNA damage checkpoint
activation and DNA repair.

subfamily is part of a larger superfamily that includes

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. Higher eukaryotes
contain two NDR isoforms, NDR1 and NDR2. Both isoforms
play a role in proper centrosome duplication. NDR1 is
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.

PKs catalyze the transfer of the gamma-phosphoryl group

of other protein serine/threonine kinases, protein

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