>gnl|CDD|173682 cd05591, STKc_nPKC_epsilon, Catalytic domain of the Protein
Serine/Threonine Kinase, Novel Protein Kinase C epsilon.
Serine/Threonine Kinases (STKs), Novel Protein Kinase C
(nPKC), epsilon isoform, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
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.

Serine/Threonine Kinase, Classical Protein Kinase C.
Serine/Threonine Kinases (STKs), Classical (or
Conventional) Protein Kinase C (cPKC) subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The cPKC 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 (PI3K). PKCs are
classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
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. cPKCs contain a
calcium-binding C2 region in their regulatory domain.
There are four cPKC isoforms, named alpha, betaI,
betaII, and gamma. cPKCs are potent kinases for
histones, myelin basic protein, and protamine. PKC-gamma
is mainly expressed in neuronal tissues. It plays a role
in protection from ischemia.

calcium-independent, but require DAG and PS for
activity, while atypical PKCs only require PS. PKCs
phosphorylate and modify the activities of a wide
variety of cellular proteins including receptors,
enzymes, cytoskeletal proteins, transcription factors,
and other kinases. They play a central role in signal
transduction pathways that regulate cell migration and
polarity, proliferation, differentiation, and apoptosis.
Also included in this subfamily are the PKC-like
proteins, called PKNs.

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
a therapeutic target in cancer. It contributes to tumor
formation and is involved in the tumor host mechanisms
of inflammation and angiogenesis.

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

(STKs), AGC (Protein Kinases A, G and C) family,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The AGC family is part
of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and Phosphoinositide 3-Kinase (PI3K). Members of
this family include cAMP-dependent Protein Kinase (PKA),
cGMP-dependent Protein Kinase (PKG), Protein Kinase C
(PKC), Protein Kinase B (PKB), G protein-coupled
Receptor Kinase (GRK), Serum- and Glucocorticoid-induced
Kinase (SGK), and 70 kDa ribosomal Protein S6 Kinase
(p70S6K or S6K), among others. AGC kinases share an
activation mechanism based on the phosphorylation of up
to three sites: the activation loop (A-loop), the
hydrophobic motif (HM) and the turn motif.
Phosphorylation at the A-loop is required of most AGC
kinases, which results in a disorder-to-order transition
of the A-loop. The ordered conformation results in the
access of substrates and ATP to the active site. A
subset of AGC kinases with C-terminal extensions
containing the HM also requires phosphorylation at this
site. Phosphorylation at the HM allows the C-terminal
extension to form an ordered structure that packs into
the hydrophobic pocket of the catalytic domain, which
then reconfigures the kinase into an active bi-lobed
state. In addition, growth factor-activated AGC kinases
such as PKB, p70S6K, RSK, MSK, PKC, and SGK, require
phosphorylation at the turn motif (also called tail or
zipper site), located N-terminal to the HM at the
C-terminal extension. AGC kinases regulate many cellular
processes including division, growth, survival,
metabolism, motility, and differentiation. Many are
implicated in the development of various human diseases.

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.

pleckstrin homology (PH) domain. ROCK is auto-inhibited
by the RBD and PH domain interacting with the catalytic
domain. It is activated via interaction with Rho GTPases
and is involved in many cellular functions including
contraction, adhesion, migration, motility,
proliferation, and apoptosis. The ROCK subfamily
consists of two isoforms, ROCK1 and ROCK2, which may be
functionally redundant in some systems, but exhibit
different tissue distributions. Both isoforms are
ubiquitously expressed in most tissues, but ROCK2 is
more prominent in brain and skeletal muscle while ROCK1
is more pronounced in the liver, testes, and kidney.
Studies in knockout mice result in different phenotypes,
suggesting that the two isoforms do not compensate for
each other during embryonic development.

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.

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

(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

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.

contain two NDR isoforms, NDR1 and NDR2. Both isoforms
play a role in proper centrosome duplication. In
addition, NDR2 plays a role in regulating neuronal
growth and differentiation, as well as in facilitating

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

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

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

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.

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

localized in the cytoplasm and shows no cell
cycle-dependent changes in its activity. It is present
in the axons of neurons and affects morphogenesis and
polarity through its regulation of microtubule
acetylation. Nek3 modulates the signaling of the
prolactin receptor through its activation of Vav2 and
contributes to prolactin-mediated motility of breast
cancer cells.

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

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

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

negatively regulate the activity of Src kinases that are
anchored to the plasma membrane. To inhibit Src kinases,
Csk is 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. Csk is
expressed in a wide variety of tissues. As a negative
regulator of Src, Csk plays a role in cell
proliferation, survival, and differentiation, and
consequently, in cancer development and progression. In
addition, Csk also shows Src-independent functions. It
is a critical component in G-protein signaling, and
plays a role in cytoskeletal reorganization and cell
migration.

intracellular signaling. CSF-1R signaling is critical in
the regulation of macrophages and osteoclasts. It leads
to increases in gene transcription and protein
translation, and induces cytoskeletal remodeling. CSF-1R
signaling leads to a variety of cellular responses
including survival, proliferation, and differentiation
of target cells. It plays an important role in innate
immunity, tissue development and function, and the
pathogenesis of some diseases including atherosclerosis
and cancer. CSF-1R signaling is also implicated in
mammary gland development during pregnancy and
lactation. Aberrant CSF-1/CSF-1R expression correlates
with tumor cell invasiveness, poor clinical prognosis,
and bone metastasis in breast cancer. Although the
structure of the human CSF-1R catalytic domain is known,
it is excluded from this specific alignment model
because it contains a deletion in its sequence.

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.

(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.
VEGFR3 (or Flt4) is a member of the VEGFR subfamily of
proteins, which are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
seven immunoglobulin (Ig)-like domains, a transmembrane
segment, and an intracellular catalytic domain. In
VEGFR3, the fifth Ig-like domain is replaced by a
disulfide bridge. The binding of VEGFRs to their
ligands, the VEGFs, leads to receptor dimerization,
activation, and intracellular signaling. VEGFR3
preferentially binds the ligands VEGFC and VEGFD. VEGFR3
is essential for lymphatic endothelial cell (EC)
development and function. It has been shown to regulate
adaptive immunity during corneal transplantation. VEGFR3
is upregulated on blood vascular ECs in pathological
conditions such as vascular tumors and the periphery of
solid tumors. It plays a role in cancer progression and
lymph node metastasis. Missense mutations in the VEGFR3
gene are associated with primary human lymphedema.

kinase domains are autoinhibited by their juxtamembrane
regions containing tyr residues. The binding to their
ligands leads to receptor dimerization, trans
phosphorylation and activation, and intracellular
signaling. PDGFR subfamily receptors are important in
the development of a variety of cells. PDGFRs are
expressed in a many cells including fibroblasts,
neurons, endometrial cells, mammary epithelial cells,
and vascular smooth muscle cells. PDGFR signaling is
critical in normal embryonic development, angiogenesis,
and wound healing. PDGFRs transduce mitogenic signals
for connective tissue cells and are important for cell
shape and motility. Kit is important in the development
of melanocytes, germ cells, mast cells, hematopoietic
stem cells, the interstitial cells of Cajal, and the
pacemaker cells of the GI tract. CSF-1R signaling is
critical in the regulation of macrophages and
osteoclasts. Mammalian FLT3 plays an important role in
the survival, proliferation, and differentiation of stem
cells.

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.

STKs catalyze the transfer of the gamma-phosphoryl group

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.

transcription, and neuronal function. This subfamily is
composed of CDK8, CDC2L6, and similar proteins. CDK8
functions 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

Mediator in complexes lacking CDK8. In VP16-dependent
transcriptional activation, CDK8 and CDC2L6 exerts
opposing effects by positive and negative regulation,
respectively, in similar conditions.

subfamily kinases are cytoplasmic (or nonreceptor) tyr
kinases containing the Src homology domains, SH3 and
SH2, N-terminal to the catalytic tyr kinase domain. They
negatively regulate the activity of Src kinases that are
anchored to the plasma membrane. To inhibit Src kinases,
Csk and Chk are translocated to the membrane via binding
to specific transmembrane proteins, G-proteins, or
adaptor proteins near the membrane. Csk catalyzes the
tyr phosphorylation of the regulatory C-terminal tail of
Src kinases, resulting in their inactivation. Chk
inhibit Src kinases using a noncatalytic mechanism by
simply binding to them. As negative regulators of Src
kinases, Csk and Chk play important roles in cell
proliferation, survival, and differentiation, and
consequently, in cancer development and progression.

variants of FGFR2 which show differential expression and
binding to FGF ligands. Disruption of either FGFR2 or
FGFR2b is lethal in mice, due to defects in the placenta
or severe impairment of tissue development including
lung, limb, and thyroid, respectively. Disruption of
FGFR2c in mice results in defective bone and skull

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.

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 catalytic 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).
Tyk2 is widely expressed in many tissues. It is involved
in signaling via the cytokine receptors IFN-alphabeta,
IL-6, IL-10, IL-12, IL-13, and IL-23. It mediates cell
surface urokinase receptor (uPAR) signaling and plays a
role in modulating vascular smooth muscle cell (VSMC)
functional behavior in response to injury. Tyk2 is also
important in dendritic cell function and T helper (Th)1
cell differentiation. A homozygous mutation of Tyk2 was
found in a patient with hyper-IgE syndrome (HIES), a
primary immunodeficiency characterized by recurrent skin
abscesses, pneumonia, and elevated serum IgE. This
suggests that Tyk2 may play important roles in multiple
cytokine signaling involved in innate and adaptive
immunity.

FGF2, FGF6, FGF19, and FGF23. FGF19 is a selective
ligand for FGFR4. Although disruption of FGFR4 in mice
causes no obvious phenotype, in vivo inhibition of FGFR4
in cultured skeletal muscle cells resulted in an arrest
of muscle progenitor differentiation. FGF6 and FGFR4 are

with a myristoylation site, followed by SH3 and SH2

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

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

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). Srm and
Brk however, lack the N-terminal myristylation sites.
Src proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,

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

is an enveloped positive-strand RNA virus of the family
Togaviridae. Virions are composed of three structural
proteins: a capsid and two membrane-spanning
glycoproteins, E2 and E1. During virus assembly, the
capsid interacts with genomic RNA to form nucleocapsids.
It has been discovered that capsid phosphorylation
serves to negatively regulate binding of viral genomic
RNA. This may delay the initiation of nucleocapsid
assembly until sufficient amounts of virus glycoproteins
accumulate at the budding site and/or prevent
non-specific binding to cellular RNA when levels of
genomic RNA are low. It follows that at a late stage in
replication, the capsid may undergo dephosphorylation
before nucleocapsid assembly occurs.

Unlike Src kinases, most Tec subfamily members (except
Rlk) also contain an N-terminal pleckstrin homology (PH)
domain, which binds the products of PI3K and allows
membrane recruitment and activation. Instead of PH, Rlk
contains an N-terminal cysteine-rich region. In addition
to PH, Tec also contains the Tec homology (TH) domain
with proline-rich and zinc-binding regions. Tec kinases
are expressed mainly by haematopoietic cells. Tec is
more widely-expressed than other Tec subfamily kinases.
It is found in endothelial cells, both B- and T-cells,
and a variety of myeloid cells including mast cells,
erythroid cells, platelets, macrophages and neutrophils.
Rlk is expressed in T-cells and mast cell lines. Tec and
Rlk are both key components of T-cell receptor (TCR)

receptor tyr kinases (RTKs) containing an extracellular
region with immunoglobulin-like, cysteine-rich, and
kringle domains, a transmembrane segment, and an

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

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

expressed only in the developing nervous system during
neurite outgrowth and neuronal differentiation,
suggesting a role for Drosophila Ror in neural

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.

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 CDKL1-5 and similar proteins. Some CDKLs,
like CDKL1 and CDKL3, may be implicated in
transformation and others, like CDKL3 and CDKL5, are
associated with mental retardation when impaired. CDKL2
plays a role in learning and memory.

Protein Tyrosine Kinases, Janus kinases 2 and 3.
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).

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

yeast has three kinetochore protein complexes. Two
complexes, Sim4 and Ndc80-MIND-Spc7 (NMS), are
constitutive components, whereas the third complex,
DASH, is transiently associated with kinetochores only
in mitosis and is required for precise chromosome
segregation. The Sim4 complex functions as a loading
dock for the DASH complex. Sim4 consists of a number of
different proteins including Ftas 1-7 and Dad1. The
equivalent higher eukaryotic protein is CENP-P. The
centromere, which is the basic element of chromosome
inheritance, is epigenetically determined in mammals.
CENP-A, the centromere-specific histone H3 variant,
assembles an array of nucleosomes and it is this that
seems to be the prime candidate for specifying
centromere identity. CENP-A nucleosomes directly recruit
a proximal CENP-A nucleosome associated complex (NAC)
comprised of CENP-M, CENP-N and CENP-T, CENP-U(50),
CENP-C and CENP-H. Assembly of the CENP-A NAC at
centromeres is dependent on CENP-M, CENP-N and CENP-T.
Additionally, there are seven other subunits which make
up the CENP-A-nucleosome distal (CAD) centromere,
CENP-K, CENP-L, CENP-O, CENP-P, CENP-Q, CENP-R and
CENP-S, also assembling on the CENP-A NAC.

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.

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. 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.

as well as proteins which contain inteins and undergo
protein splicing (e.g. DnaB, RIR1-2, GyrA and Pol). In
protein splicing an intervening polypeptide sequence -
the intein - is excised from a protein, and the flanking
polypeptide sequences - the exteins - are joined by a
peptide bond. In addition to the autocatalytic splicing
domain, many inteins contain an inserted endonuclease
domain, which plays a role in spreading inteins.
Hedgehog proteins are a major class of intercellular
signaling molecules, which control inductive
interactions during animal development. The mature
signaling forms of hedgehog proteins are the N-terminal
fragments, which are covalently linked to cholesterol at
their C-termini. This modification is the result of an
autoprocessing step catalyzed by the C-terminal
fragments, which are aligned here.

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).
MKK3 and MKK6 are dual-specificity PKs that
phosphorylate and activate their downstream target, p38
MAPK, on specific threonine and tyrosine residues.
MKK3/6 plays roles in the regulation of cell cycle
progression, cytokine- and stress-induced apoptosis,
oncogenic transformation, and adult tissue regeneration.
In addition, MKK6 plays a critical role in osteoclast
survival in inflammatory disease while MKK3 is
associated with tumor invasion, progression, and poor
patient survival in glioma.
