>gnl|CDD|173727 cd06613, STKc_MAP4K3_like, Catalytic domain of Mitogen-activated
protein kinase kinase kinase kinase-like Protein
Serine/Threonine Kinases. Serine/threonine kinases
(STKs), mitogen-activated protein kinase (MAPK) kinase
kinase kinase 3 (MAPKKKK3 or MAP4K3)-like subfamily,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The MAP4K3-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 includes
MAP4K3, MAP4K1, MAP4K2, MAP4K5, and related proteins.
Vertebrate members contain an N-terminal catalytic
domain and a C-terminal citron homology (CNH)
regulatory domain, similar to MAP4K4/6. MAP4Ks are
involved in some MAPK signaling pathways that are
important in mediating cellular responses to
extracellular signals by activating a MAPK kinase
kinase (MAPKKK or MAP3K or MKKK). Each MAPK cascade is
activated either by a small GTP-binding protein or by
an adaptor protein, which transmits the signal either
directly to a MAP3K to start the triple kinase core
cascade or indirectly through a mediator kinase, a
MAP4K. MAP4K1, also called haematopoietic progenitor
kinase 1 (HPK1), is a hematopoietic-specific STK
involved in many cellular signaling cascades including
MAPK, antigen receptor, apoptosis, growth factor, and
cytokine signaling. It participates in the regulation
of T cell receptor signaling and T cell-mediated immune
responses. MAP4K2 was referred to as germinal center
(GC) kinase because of its preferred location in GC B
cells. MAP4K3 plays a role in the nutrient-responsive
pathway of mTOR (mammalian target of rapamycin)
signaling. It is required in the activation of S6
kinase by amino acids and for the phosphorylation of
the mTOR-regulated inhibitor of eukaryotic initiation
factor 4E. MAP4K5, also called germinal center
kinase-related enzyme (GCKR), has been shown to
activate the MAPK c-Jun N-terminal kinase (JNK).

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

Serine/Threonine Kinases, Mammalian Ste20-like protein
kinase 1 and 2. Serine/threonine kinases (STKs),
mammalian Ste20-like protein kinase 1 (MST1) and MST2
subfamily, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
MST1/2 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 MST1, MST2, and related proteins including
Drosophila Hippo and Dictyostelium discoideum Krs1
(kinase responsive to stress 1). MST1/2 and Hippo are
involved in a conserved pathway that governs cell
contact inhibition, organ size control, and tumor
development. MST1 activates the mitogen-activated
protein kinases (MAPKs) p38 and c-Jun N-terminal kinase
(JNK) through MKK7 (a MAPK kinase) and MEKK1 (a MAPK
kinase kinase) by acting as a MAPK kinase kinase kinase
(MAPKKKK). Activation of JNK by MST1 leads to caspase
activation and apoptosis. MST1 has also been implicated
in cell proliferation and differentiation. Krs1 may
regulate cell growth arrest and apoptosis in response
to cellular stress.

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.

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.

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

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

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.

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

TAO1 is sometimes referred to as prostate-derived
sterile 20-like kinase 2 (PSK2). TAO1 activates the p38
MAPK through direct interaction with and activation of
MEK3. TAO1 is highly expressed in the brain and may play
a role in neuronal apoptosis. TAO1 interacts with the
checkpoint proteins BubR1 and Mad2, and plays an
important role in regulating mitotic progression, which
is required for both chromosome congression and
checkpoint-induced anaphase delay. TAO1 may play a role
in protecting genomic stability.

Human TAO2 is also known as prostate-derived Ste20-like
kinase (PSK) and was identified in a screen for
overexpressed RNAs in prostate cancer. TAO2 activates
both p38 and c-Jun N-terminal kinase (JNK), by
phosphorylating and activating the respective MAP/ERK
kinases (MEKs, also known as MKKs or MAPKKs), MEK3/MEK6
and MKK4/MKK7. TAO2 contains a long C-terminal extension
with autoinhibitory segments. It is activated by the
release of this inhibition and the phosphorylation of
its activation loop serine. TAO2 functions as a
regulator of actin cytoskeletal and microtubule
organization. In addition, it regulates the transforming
growth factor-activated kinase 1 (TAK1), which is a
MAPKKK that plays an essential role in the signaling
pathways of tumor necrosis factor (TNF), interleukin 1
(IL-1), and Toll-like receptor (TLR).

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

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.

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

with the scaffolding protein MO25, and the STK, LKB1,
resulting in the activation of the kinase. In the
complex, LKB1 phosphorylates and activates adenosine
monophosphate-activated protein kinases (AMPKs), which
regulate cell energy metabolism and cell polarity. LKB1
is a tumor suppressor linked to the rare inherited
disease, Peutz-Jeghers syndrome, which is characterized
by a predisposition to benign polyps and
hyperpigmentation of the buccal mucosa. There are two
forms of STRAD, alpha and beta, that complex with LKB1
and MO25. The structure of STRAD-alpha is available and
shows that this protein binds ATP, has an ordered
activation loop, and adopts a closed conformation
typical of fully active protein kinases. It does not
possess activity due to nonconservative substitutions
of essential catalytic residues. ATP binding enhances
the affinity of STRAD for MO25. The conformation of
STRAD-alpha, stabilized through ATP and MO25, may be
needed to activate LKB1. A mutation which results in a
truncation of a C-terminal part of the human
STRAD-alpha pseudokinase domain and disrupts its

other protein STKs, protein tyrosine kinases, RIO
kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. Nek6 and Nek7
are the shortest Neks, consisting only of the catalytic
domain and a very short N-terminal extension. They show
distinct expression patterns and both appear to be
downstream substrates of Nek9. They are required for
mitotic spindle formation and cytokinesis. They may
also be regulators of the p70 ribosomal S6 kinase.

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

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.

includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside

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, classical PKCs depend on calcium,
DAG (1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. Novel PKCs are
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.

kinases, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and

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.

kinases are cytoplasmic (or nonreceptor) tyr kinases
(nRTKs) with similarity to Src kinases in that they

SH2) N-terminal to the catalytic tyr kinase domain.
Unlike Src kinases, most Tec subfamily members (except

(PH) domain, which binds the products of PI3K and
allows membrane recruitment and activation. In
addition, some members contain the Tec homology (TH)

regions. Tec kinases form the second largest subfamily
of nRTKs and are expressed mainly by haematopoietic
cells, although Tec and Bmx are also found in
endothelial cells. B-cells express Btk and Tec, while
T-cells express Itk, Txk, and Tec. Collectively, Tec
kinases are expressed in a variety of myeloid cells
such as mast cells, platelets, macrophages, and
dendritic cells. Each Tec kinase shows a distinct
cell-type pattern of expression. The function of Tec
kinases in lymphoid cells have been studied
extensively. They play important roles in the

the FGFs, results in receptor dimerization and
activation, and intracellular signaling. The binding of
FGFs to FGFRs is promiscuous, in that a receptor may be
activated by several ligands and a ligand may bind to
more that one type of receptor. Many FGFR3 splice
variants have been reported with the IIIb and IIIc
isoforms being the predominant forms. FGFR3 IIIc is the
isoform expressed in chondrocytes, the cells affected in
dwarfism, while IIIb is expressed in epithelial cells.
FGFR3 ligands include FGF1, FGF2, FGF4, FGF8, FGF9, and

In the cochlear duct and in the lens, FGFR3 is involved
in differentiation while it appears to have a role in
cell proliferation in epithelial cells. Germline
mutations in FGFR3 are associated with skeletal
disorders including several forms of dwarfism. Some
missense mutations are associated with multiple myeloma
and carcinomas of the bladder and cervix. Overexpression
of FGFR3 is found in thyroid carcinoma.

Protein Tyrosine Kinase (PTK) family; Platelet Derived
Growth Factor Receptor (PDGFR) beta; 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. PDGFR
beta is a receptor tyr kinase (RTK) containing an
extracellular ligand-binding region with five
immunoglobulin-like domains, a transmembrane segment,
and an intracellular catalytic domain. The binding to
its ligands, the PDGFs, leads to receptor dimerization,
trans phosphorylation and activation, and intracellular
signaling. PDGFR beta forms homodimers or heterodimers
with PDGFR alpha, depending on the nature of the PDGF
ligand. PDGF-BB and PDGF-DD induce PDGFR beta
homodimerization. PDGFR signaling plays many roles in
normal embryonic development and adult physiology. PDGFR
beta signaling leads to a variety of cellular effects
including the stimulation of cell growth and chemotaxis,
as well as the inhibition of apoptosis and GAP
junctional communication. It is critical in normal
angiogenesis as it is involved in the recruitment of
pericytes and smooth muscle cells essential for vessel
stability. Aberrant PDGFR beta expression is associated
with some human cancers. The continuously-active fusion
proteins of PDGFR beta with COL1A1 and TEL are
associated with dermatofibrosarcoma protuberans (DFSP)
and a subset of chronic myelomonocytic leukemia (CMML),
respectively.

FGFs to FGFRs is promiscuous, in that a receptor may be
activated by several ligands and a ligand may bind to
more that one type of receptor. Alternative splicing of
FGFR1 transcripts produces a variety of isoforms, which
are differentially expressed in cells. FGFR1 binds the
ligands, FGF1 and FGF2, with high affinity and has also
been reported to bind FGF4, FGF6, and FGF9. FGFR1
signaling is critical in the control of cell migration
during embryo development. It promotes cell
proliferation in fibroblasts. Nuclear FGFR1 plays a role
in the regulation of transcription. Mutations,
insertions or deletions of FGFR1 have been identified in
patients with Kallman's syndrome (KS), an inherited
disorder characterized by hypogonadotropic hypogonadism
and loss of olfaction. Aberrant FGFR1 expression has
been found in some human cancers including 8P11

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.

phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Abl (or
c-Abl) is a ubiquitously-expressed cytoplasmic (or
nonreceptor) tyr kinase that contains SH3, SH2, and tyr
kinase domains in its N-terminal region, as well as
nuclear localization motifs, a putative DNA-binding
domain, and F- and G-actin binding domains in its
C-terminal tail. It also contains a short
autoinhibitory cap region in its N-terminus. Abl is
normally inactive and requires phosphorylation and
myristoylation for activation. Abl function depends on
its subcellular localization. In the cytoplasm, Abl
plays a role in cell proliferation and survival. In
response to DNA damage or oxidative stress, Abl is
transported to the nucleus where it induces apoptosis.
In chronic myelogenous leukemia (CML) patients, an
aberrant translocation results in the replacement of
the first exon of Abl with the BCR (breakpoint cluster
region) gene. The resulting BCR-Abl fusion protein is
constitutively active and associates into tetramers,
resulting in a hyperactive kinase sending a continuous
signal. This leads to uncontrolled proliferation,
morphological transformation and anti-apoptotic
effects. BCR-Abl is the target of selective inhibitors,
such as imatinib (Gleevec), used in the treatment of
CML. Abl2, also known as ARG (Abelson-related gene), is
thought to play a cooperative role with Abl in the
proper development of the nervous system. The Tel-ARG
fusion protein, resulting from reciprocal translocation
between chromosomes 1 and 12, is associated with acute
myeloid leukemia (AML). The TEL gene is a frequent
fusion partner of other tyr kinase oncogenes, including
Tel/Abl, Tel/PDGFRbeta, and Tel/Jak2, found in patients
with leukemia and myeloproliferative disorders.

there is only one splice form of FGFR4. It binds FGF1,
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
uniquely expressed in myofibers and satellite cells.
FGF6/FGFR4 signaling appears to play a key role in the

kinase-like Protein Tyrosine Kinases. Protein Tyrosine
Kinase (PTK) family; Human Fyn-related kinase (Frk) and
similar proteins; 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. Frk and
Srk 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. Frk, also known as Rak, is
specifically expressed in liver, lung, kidney,
intestine, mammary glands, and the islets of
Langerhans. Rodent homologs were previously referred to
as GTK (gastrointestinal tyr kinase), BSK (beta-cell
Src-like kinase), or IYK (intestinal tyr kinase).
Studies in mice reveal that Frk is not essential for
viability. It plays a role in the signaling that leads
to cytokine-induced beta-cell death in Type I diabetes.
It also regulates beta-cell number during embryogenesis
and early in life.

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. FAK is a
cytoplasmic (or nonreceptor) tyr kinase that contains an
autophosphorylation site and a FERM domain at the
N-terminus, a central tyr kinase domain, proline-rich
regions, and a C-terminal FAT (focal adhesion targeting)
domain. FAK activity is dependent on integrin-mediated
cell adhesion, which facilitates N-terminal
autophosphorylation. Full activation is achieved by the
phosphorylation of its two adjacent A-loop tyrosines.
FAK is important in mediating signaling initiated at
sites of cell adhesions and at growth factor receptors.
Through diverse molecular interactions, FAK functions as
a biosensor or integrator to control cell motility. It
is a key regulator of cell survival, proliferation,
migration and invasion, and thus plays an important role
in the development and progression of cancer. Src binds
to autophosphorylated FAK forming the FAK-Src dual
kinase complex, which is activated in a wide variety of
tumor cells and generates signals promoting growth and
metastasis. FAK is being developed as a target for
cancer therapy.

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.

(1,2-diacylglycerol), and in most cases,

calcium-binding C2 region in their regulatory domain.
There are four cPKC isoforms, named alpha, betaI,

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. EphRs
comprise the largest subfamily of receptor tyr kinases
(RTKs). They can be classified into two classes (EphA
and EphB), according to their extracellular sequences,
which largely correspond to binding preferences for
either GPI-anchored ephrin-A ligands or transmembrane
ephrin-B ligands. Vertebrates have ten EphA and six
EhpB receptors, which display promiscuous ligand
interactions within each class. EphRs contain an ephrin
binding domain and two fibronectin repeats
extracellularly, a transmembrane segment, and a
cytoplasmic tyr kinase domain. Binding of the ephrin
ligand to EphR requires cell-cell contact since both
are anchored to the plasma membrane. This allows
ephrin/EphR dimers to form, leading to the activation
of the intracellular tyr kinase domain. The resulting
downstream signals occur bidirectionally in both
EphR-expressing cells (forward signaling) and
ephrin-expressing cells (reverse signaling). The main
effect of ephrin/EphR interaction is cell-cell
repulsion or adhesion. Ephrin/EphR signaling is
important in neural development and plasticity, cell
morphogenesis and proliferation, cell-fate
determination, embryonic development, tissue
patterning, and angiogenesis.

movement in order to optimize the photosynthetic
efficiency of plants. They are light-activated STKs
