>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|173624 cd00192, PTKc, Catalytic domain of Protein Tyrosine Kinases.
Protein Tyrosine Kinase (PTK) family, catalytic domain.
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.

kinase-like Protein Tyrosine Kinases. Protein Tyrosine
Kinase (PTK) family; C-terminal Src kinase (Csk)
subfamily; catalytic (c) domain. The Csk subfamily is
composed of Csk, Chk, 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. 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. 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.

Kinase (PTK) family; Janus kinase (Jak) subfamily;

proteins. The PTKc family is part of a larger

catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
Jak subfamily proteins 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
catalytic domain. Most Jaks are expressed in a wide
variety of tissues, except for Jak3, which is expressed
only in hematopoietic cells. 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).
Jaks are also involved in regulating the surface
expression of some cytokine receptors. The Jak-STAT
pathway is involved in many biological processes
including hematopoiesis, immunoregulation, host defense,
fertility, lactation, growth, and embryogenesis.

>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

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.

family; Met and Ron; catalytic (c) domain. The PTKc
family is part of a larger superfamily that includes the

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. Met and
Ron are receptor tyr kinases (RTKs) composed of an
alpha-beta heterodimer. The extracellular alpha chain is
disulfide linked to the beta chain, which contains an
extracellular ligand-binding region with a sema domain,
a PSI domain and four IPT repeats, a transmembrane
segment, and an intracellular catalytic domain. Binding
to their ligands leads to receptor dimerization,
autophosphorylation, activation, and intracellular
signaling. Met binds to the ligand, hepatocyte growth
factor/scatter factor (HGF/SF), and is also called the
HGF receptor. HGF/Met signaling plays a role in growth,
transformation, cell motility, invasion, metastasis,
angiogenesis, wound healing, and tissue regeneration.
Aberrant expression of Met through mutations or gene
amplification is associated with many human cancers
including hereditary papillary renal and gastric
carcinomas. The ligand for Ron is macrophage stimulating
protein (MSP). Ron signaling is important in regulating
cell motility, adhesion, proliferation, and apoptosis.
Aberrant Ron expression is implicated in tumorigenesis
and metastasis.

known as Tsk or Emt) is a member of the Tec subfamily of
proteins, which are cytoplasmic (or nonreceptor) tyr
kinases with similarity to Src kinases in that they
contain Src homology protein interaction domains (SH3,
SH2) N-terminal to the catalytic tyr kinase domain.
Unlike Src kinases, most Tec subfamily members (except
Rlk) also contain an N-terminal pleckstrin homology (PH)
domain, which binds the products of PI3K and allows
membrane recruitment and activation. In addition, Itk
contains the Tec homology (TH) domain containing one
proline-rich region and a zinc-binding region. Tec
kinases are expressed mainly by haematopoietic cells.
Itk is expressed in T-cells and mast cells, and is
important in their development and differentiation. Of
the three Tec kinases expressed in T-cells, Itk plays
the predominant role in T-cell receptor (TCR) signaling.
It is activated by phosphorylation upon TCR crosslinking
and is involved in the pathway resulting in
phospholipase C-gamma1 activation and actin
polymerization. It also plays a role in the downstream
signaling of the T-cell costimulatory receptor CD28, the
T-cell surface receptor CD2, and the chemokine receptor
CXCR4. In addition, Itk is crucial for the development
of T-helper(Th)2 effector responses.

(Fujinami poultry sarcoma) were first isolated from
tumor-causing retroviruses. The viral oncogenes encode
chimeric Fes proteins consisting of Gag sequences at the

Fes and Fer kinases play roles in haematopoiesis,
inflammation and immunity, growth factor signaling,
cytoskeletal regulation, cell migration and adhesion,
and the regulation of cell-cell interactions. Fes and
Fer show redundancy in their biological functions.

to the N-terminal domain of Wnt inhibitory factor-1
(WIF) and serves as the ligand (Wnt) binding domain of
Ryk. Ryk is expressed in many different tissues both
during development and in adults, suggesting a
widespread function. It acts as a chemorepulsive axon
guidance receptor of Wnt glycoproteins and is
responsible for the establishment of axon tracts during
the development of the central nervous system. In
addition, studies in mice reveal that Ryk is essential
in skeletal, craniofacial, and cardiac development.
Thus, it appears Ryk is involved in signal transduction
despite its lack of kinase activity. Ryk may function as
an accessory protein that modulates the signals coming
from catalytically active partner RTKs such as the Eph
receptors.

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.

Abelson kinase. Protein Tyrosine Kinase (PTK) family;
Abelson (Abl) kinase; 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. 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.

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.

Kinases, Class EphB Ephrin Receptors. Protein Tyrosine
Kinase (PTK) family; Ephrin Receptor (EphR) subfamily;
class EphB receptors; 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. EphRs
comprise the largest subfamily of receptor tyr kinases
(RTKs). Class EphB receptors bind to transmembrane
ephrin-B ligands. There are six vertebrate EhpB
receptors (EphB1-6), which display promiscuous
interactions with three ephrin-B ligands. One exception
is EphB2, which also interacts with ephrin A5. 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. The resulting
downstream signals occur bidirectionally in both
EphR-expressing cells (forward signaling) and
ephrin-expressing cells (reverse signaling). Ephrin/EphR
interaction mainly results in cell-cell repulsion or
adhesion. EphBRs play important roles in synapse
formation and plasticity, spine morphogenesis, axon
guidance, and angiogenesis. In the intestinal
epithelium, EphBRs are Wnt signaling target genes that
control cell compartmentalization. They function as
suppressors of color cancer progression.

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. Srm and
Brk are a member of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases in general 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). Srm and
Brk however, lack the N-terminal myristylation sites.
Src proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Brk has been found to be overexpressed
in a majority of breast tumors.

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.

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. 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.

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).

Yes. Protein Tyrosine Kinase (PTK) family; Yes kinase;
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. Yes (or c-Yes) 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. c-Yes
kinase is the cellular homolog of the oncogenic protein
(v-Yes) encoded by the Yamaguchi 73 and Esh sarcoma
viruses. It displays functional overlap with other Src
subfamily members, particularly Src. It also shows some
unique functions such as binding to occludins,
transmembrane proteins that regulate extracellular
interactions in tight junctions. Yes also associates
with a number of proteins in different cell types that
Src does not interact with, like JAK2 and gp130 in
pre-adipocytes, and Pyk2 in treated pulmonary vein
endothelial cells. Although the biological function of
Yes remains unclear, it appears to have a role in
regulating cell-cell interactions and vesicle
trafficking in polarized cells.

Protein Tyrosine Kinase (PTK) family; Receptor tyrosine

(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 Aatyk subfamily is also referred to as the lemur

(Lmtk1), Aatyk2 (Lmtk2, Brek), Aatyk3 (Lmtk3), and
similar proteins. The PTKc family is part of a larger

catalyze the transfer of the gamma-phosphoryl group from

Aatyk proteins are mostly receptor tyr kinases (RTKs)
containing a transmembrane segment and a long C-terminal
cytoplasmic tail with a catalytic domain. Aatyk1 does
not contain a transmembrane segment and is a cytoplasmic
(or nonreceptor) kinase. Aatyk proteins are classified
as tyr kinases based on overall sequence similarity and
the phylogenetic tree. However, analysis of catalytic

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.

receptor; 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. EphRs
comprise the largest subfamily of receptor tyr kinases
(RTKs). In general, class EphA receptors bind
GPI-anchored ephrin-A ligands. There are ten vertebrate
EphA receptors (EphA1-10), which display promiscuous
interactions with six ephrin-A ligands. 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. The resulting
downstream signals occur bidirectionally in both
EphR-expressing cells (forward signaling) and
ephrin-expressing cells (reverse signaling). EphA10,
which contains an inactive tyr kinase domain, may
function to attenuate signals of co-clustered active
receptors. EphA10 is mainly expressed in the testis.
Ephrin/EphR interaction results in cell-cell repulsion
or adhesion, making it important in neural development
and plasticity, cell morphogenesis, cell-fate
determination, embryonic development, tissue patterning,
and angiogenesis.

NT3/TrkC signaling plays an important role in the
innervation of the cardiac conducting system and the
development of smooth muscle cells. Mice deficient with
NT3 and TrkC have multiple heart defects. NT3/TrkC
signaling is also critical for the development and
maintenance of enteric neurons that are important for
the control of gut peristalsis.

development of acute myeloid leukemia (AML). In
addition, Hck is essential in regulating the
degranulation of polymorphonuclear leukocytes (PMNs).
Genetic polymorphisms affect the expression level of
Hck, which affects PMN mediator release and influences
the development of chronic obstructive pulmonary disease

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.

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)

cytoplasmic (or non-receptor) tyr kinase, containing 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 with a conserved tyr.
It is activated by autophosphorylation at the tyr kinase
domain, and is negatively regulated by phosphorylation
at the C-terminal tyr by Csk (C-terminal Src Kinase).
c-Src is the vertebrate homolog of the oncogenic protein
(v-Src) from Rous sarcoma virus. Together with other Src
subfamily proteins, it is involved in signaling pathways
that regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Src also play a role in regulating cell
adhesion, invasion, and motility in cancer cells and
tumor vasculature, contributing to cancer progression
and metastasis. Elevated levels of Src kinase activity
have been reported in a variety of human cancers.
Several inhibitors of Src have been developed as
anti-cancer drugs. Src is also implicated in acute
inflammatory responses and osteoclast function.

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
FGF23. It is a negative regulator of long bone growth.
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.

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.

(HER, ErbB) subfamily members include EGFR (HER1,

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.

Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK9
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

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.

Serine/Threonine Kinase, MAP/ERK kinase kinase 4.
Serine/threonine kinases (STKs), MAP/ERK kinase kinase 4
(MEKK4) subfamily, catalytic (c) domain. STKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
MEKK4 subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. MEKK4 is a mitogen-activated protein kinase
(MAPK) kinase kinase (MAPKKK or MKKK or MAP3K), that
phosphorylates and activates MAPK kinases (MAPKKs or
MKKs or MAP2Ks), which in turn phosphorylate and
activate MAPKs during signaling cascades that are
important in mediating cellular responses to
extracellular signals. MEKK4 activates the c-Jun
N-terminal kinase (JNK) and p38 MAPK signaling pathways
by directly activating their respective MAPKKs,
MKK4/MKK7 and MKK3/MKK6. JNK and p38 are collectively
known as stress-activated MAPKs, as they are activated
in response to a variety of environmental stresses and
pro-inflammatory cytokines. MEKK4 also plays roles in
the re-polarization of the actin cytoskeleton in
response to osmotic stress, in the proper closure of the
neural tube, in cardiovascular development, and in
immune responses.

tyrosine (tyr) residues in protein substrates. EphRs
comprise the largest subfamily of receptor tyr kinases
(RTKs). In general, class EphA receptors bind
GPI-anchored ephrin-A ligands. There are ten vertebrate
EphA receptors (EphA1-10), which display promiscuous
interactions with six ephrin-A ligands. 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. The resulting
downstream signals occur bidirectionally in both
EphR-expressing cells (forward signaling) and
ephrin-expressing cells (reverse signaling). Ephrin/EphR
interaction mainly results in cell-cell repulsion or
adhesion, making it important in neural development and
plasticity, cell morphogenesis, cell-fate determination,
embryonic development, tissue patterning, and
angiogenesis. The EphA2 receptor is overexpressed in
tumor cells and tumor blood vessels in a variety of
cancers including breast, prostate, lung, and colon. As
a result, it is an attractive target for drug design
since its inhibition could affect several aspects of
tumor progression.

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,

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.

PDGFR subfamily members are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
five immunoglobulin-like domains, a transmembrane
segment, and an intracellular catalytic domain. PDGFR
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

Together, they are involved in the control of cell-cycle
progression, transcription, and neuronal function. CDK5
is unusual in that it is regulated by non-cyclin
proteins, p35 and p39. It is highly expressed in the
nervous system and is critical in normal neural
development and function. It plays a role in neuronal
migration and differentiation, and is also important in
synaptic plasticity and learning. CDK5 also participates

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

receptor tyr kinase (RTK) containing an extracellular
region with four cadherin-like repeats, a
calcium-binding site, and a cysteine-rich domain, a
transmembrane segment, and an intracellular catalytic
domain. It is part of a multisubunit complex that binds
glial-derived neurotropic factor (GDNF) family ligands
(GFLs) including GDNF, neurturin, artemin, and
persephin. GFLs bind RET along with four GPI-anchored
coreceptors, bringing two RET molecules together,
leading to autophosphorylation, activation, and
intracellular signaling. RET is essential for the
development of the sympathetic, parasympathetic and
enteric nervous systems, and the kidney. RET disruption
by germline mutations causes diseases in humans
including congenital aganglionosis of the
gastrointestinal tract (Hirschsprung's disease) and
three related inherited cancers: multiple endocrine
neoplasia type 2A (MEN2A), MEN2B, and familial medullary
thyroid carcinoma (FMTC).

pseudokinase domain shows similarity to protein kinases
but lacks crucial residues for catalytic activity. STRAD
forms a complex 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.

released from motor neurons, stimulates Musk
autophosphorylation and activation, leading to the
clustering of acetylcholine receptors (AChRs). To date,
there is no evidence to suggest that agrin binds
directly to Musk. Mutations in AChR, Musk and other

usually activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain. C-ros is
expressed in embryonic cells of the kidney, intestine
and lung, but disappears soon after birth. It persists
only in the adult epididymis. Male mice bearing inactive

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.

to Tie2 leads to receptor autophosphorylation and
activation, promoting cell migration and survival. In
contrast, Ang-2 binding to Tie2 does not result in the

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
phosphorylates pRB specifically during the G0/G1
transition. This phosphorylation is required for cells
to exit G0 efficiently and enter the G1 phase.

kinases (STKs), mitogen-activated protein kinase (MAPK)
kinase kinase kinase 4 (MAPKKKK4 or MAP4K4) and MAPKKKK6
(or MAP4K6) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The MAP4K4/MAP4K6 subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. Members of this subfamily
contain an N-terminal catalytic domain and a C-terminal
citron homology (CNH) regulatory domain. MAP4Ks (or
MAPKKKKs) are involved in MAPK signaling pathways that
are important in mediating cellular responses to
extracellular signals by activating a MAPK kinase kinase
(MAPKKK or MAP3K or MKKK). Each MAPK cascade is
activated either by a small GTP-binding protein or by an
adaptor protein, which transmits the signal either
directly to a MAP3K to start the triple kinase core
cascade or indirectly through a mediator kinase, a
MAP4K. MAP4K4 is also called Nck Interacting kinase
(NIK). It facilitates the activation of the MAPKs,
extracellular signal-regulated kinase (ERK) 1, ERK2, and
c-Jun N-terminal kinase (JNK), by phosphorylating and
activating MEKK1. MAP4K4 plays a role in tumor necrosis
factor (TNF) alpha-induced insulin resistance. MAP4K4
silencing in skeletal muscle cells from type II diabetic
patients restores insulin-mediated glucose uptake.
MAP4K4, through JNK, also plays a broad role in cell
motility, which impacts inflammation, homeostasis, as
well as the invasion and spread of cancer. MAP4K4 is
found to be highly expressed in most tumor cell lines
relative to normal tissue. MAP4K6 (also called MINK for
Misshapen/NIKs-related kinase) is activated after Ras
induction and mediates activation of p38 MAPK. MAP4K6
plays a role in cell cycle arrest, cytoskeleton
organization, cell adhesion, and cell motility.

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. 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. Ror2 plays important roles in skeletal
and heart formation. Ror2-deficient mice show widespread
bone abnormalities, ventricular defects in the heart,
and respiratory dysfunction. Mutations in human Ror2
result in two different bone development genetic
disorders, recessive Robinow syndrome and brachydactyly
type B. Ror2 is also implicated in neural development.

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.

Protein Tyrosine Kinase (PTK) family; Vascular
Endothelial Growth Factor Receptor (VEGFR) subfamily;
catalytic (c) domain. The VEGFR subfamily consists of
VEGFR1 (Flt1), VEGFR2 (Flk1), VEGFR3 (Flt4), 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

catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
VEGFR subfamily members 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. There are five
VEGF ligands in mammals, which bind, in an overlapping
pattern to the three VEGFRs, which can form homo or
heterodimers. VEGFRs regulate the cardiovascular system.
They are critical for vascular development during
embryogenesis and blood vessel formation in adults. They
induce cellular functions common to other growth factor
receptors such as cell migration, survival, and
proliferation. VEGFR1 binds VEGFA, VEGFB, and placenta
growth factor (PLGF). It regulates monocyte and
macrophage migration, vascular permeability,
haematopoiesis, and the recruitment of haematopietic
progenitor cells from the bone marrow.

alpha 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 alpha forms homodimers or heterodimers
with PDGFR beta, depending on the nature of the PDGF
ligand. PDGF-AA, PDGF-AB, and PDGF-CC induce PDGFR alpha
homodimerization. PDGFR signaling plays many roles in
normal embryonic development and adult physiology. PDGFR
alpha signaling is important in the formation of lung
alveoli, intestinal villi, mesenchymal dermis, and hair
follicles, as well as in the development of
oligodendrocytes, retinal astrocytes, neural crest
cells, and testicular cells. Aberrant PDGFR alpha
expression is associated with some human cancers.
Mutations in PDGFR alpha have been found within a subset
of gastrointestinal stromal tumors (GISTs). An active
fusion protein FIP1L1-PDGFR alpha, derived from
interstitial deletion, is associated with idiopathic
hypereosinophilic syndrome (HES) and chronic
eosinophilic leukemia (CEL).

from the spleen, and its function in hematopoietic cells
is well-established. Syk is involved in the signaling
downstream of activated receptors (including B-cell and
Fc receptors) that contain ITAMs (immunoreceptor tyr

function including bone development. In breast
epithelial cells, where Syk acts as a negative regulator
for epidermal growth factor receptor (EGFR) signaling,
loss of Syk expression is associated with abnormal
proliferation during cancer development suggesting a
potential role as a tumor suppressor. In mice, Syk has
been shown to inhibit malignant transformation of

protein Kinase 9-like Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Cyclin-Dependent
protein Kinase 9 (CDK9)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The CDK9-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. This subfamily is
composed of CDK9 and CDK12 from higher eukaryotes, yeast
BUR1, C-type plant CDKs (CdkC), and similar proteins.
CDK9, BUR1, and CdkC are functionally equivalent. They
act as a kinase for the C-terminal domain of RNA
polymerase II and participate in regulating mutliple
steps of gene expression including transcription
elongation and RNA processing. CDK9 and CdkC associate
with T-type cyclins while BUR1 associates with the
cyclin BUR2. CDK12 is a unique CDK that contains an
arginine/serine-rich (RS) domain, which is predominantly
found in splicing factors. CDK12 interacts with cyclins
L1 and L2, and participates in regulating transcription
and alternative splicing.

addition to a central catalytic domain, which also
contains an insert relative to MAST kinases like MASTL.
Rim15 contains a C-terminal signal receiver (REC) domain
while cek1 contains an N-terminal PAS domain. MAST
kinases are cytoskeletal associated kinases of unknown
function that are also expressed at neuromuscular
junctions and postsynaptic densities. The fungal
proteins Rim15 and cek1 are involved in the regulation
of meiosis and mitosis, respectively.

phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to

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.

to play an important role in mammalian neural
development as well as visceral muscle differentiation

proteins, due to chromosomal translocations, in about
60% of anaplastic large cell lymphomas (ALCLs). ALK
fusion proteins are also found in rare cases of diffuse
large B cell lymphomas (DLBCLs). LTK is mainly expressed
in B lymphocytes and neuronal tissues. It is important
in cell proliferation and survival. Transgenic mice

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.

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.

widely expressed in many tissues with the highest levels
found in skeletal muscle, skin, kidney and lung. It is
important in cell proliferation and development. Mice,
with a deletion of DDR2, suffer from dwarfism and
delayed healing of epidermal wounds. DDR2 also
contributes to collagen (type I) regulation by
inhibiting fibrillogenesis and altering the morphology
of collagen fibers. It is also expressed in immature
dendritic cells (DCs), where it plays a role in DC
activation and function.

the neuregulins (or heregulins) and some EGFR (HER1)
ligands including betacellulin, HBEGF, and epiregulin.
All four neuregulins (NRG1-4) interact with HER4. Upon
ligand binding, HER4 forms homo- or heterodimers with
other HER proteins. HER4 is essential in embryonic
development. It is implicated in mammary gland, cardiac,
and neural development. As a postsynaptic receptor of
NRG1, HER4 plays an important role in synaptic
plasticity and maturation. The impairment of NRG1/HER4

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

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.

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

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.

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.

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),

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

The PAK subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PAKs are Rho family GTPase-regulated kinases
that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
Group II PAKs, also called non-conventional PAKs,
include PAK4, PAK5, and PAK6. Group II PAKs contain PBD
(p21-binding domain) and catalytic domains, but lack
other motifs found in group I PAKs, such as an AID
(autoinhibitory domain) and SH3 binding sites. Since
group II PAKs do not contain an obvious AID, they may be
regulated differently from group I PAKs. While group I

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 Byr1 from
Schizosaccharomyces pombe, FUZ7 from Ustilago maydis,
and related proteins. Byr1 phosphorylates its downstream
target, the MAPK Spk1, and is regulated by the MAPKKK
Byr2. The Spk1 cascade is pheromone-responsive and is
essential for sporulation and sexual differentiation in
fission yeast. FUZ7 phosphorylates and activates its
target, the MAPK Crk1, which is required in mating and
virulence in U. maydis.

immunoglobulin-like domains, a transmembrane segment,
and an intracellular catalytic domain. The binding of
CSF-1R to its ligand, CSF-1, leads to receptor
dimerization, trans phosphorylation and activation, and
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.

of plant MAPKs based on the conserved phosphorylation
motif present in the activation loop, TEY and TDY. This

are also key regulators for stomatal development and
patterning. Group B is represented by AtMPK4, AtMPK13,

(Jak2) and Jak3; pseudokinase domain (repeat 1). 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. 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 tyr kinase domain. The pseudokinase
domain shows similarity to tyr kinases but lacks crucial
residues for catalytic activity and ATP binding. It
modulates the kinase activity of the C-terminal
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). 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).

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.
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.

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

(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.

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.

least 10 isoforms. JNKs are specifically activated by
the MAPK kinases MKK4 and MKK7, which are in turn

>gnl|CDD|173643 cd05077, PTK_Jak1_rpt1, Pseudokinase (repeat 1) domain of the
Protein Tyrosine Kinase, Janus kinase 1. Protein
Tyrosine Kinase (PTK) family; Janus kinase 1 (Jak1);
pseudokinase domain (repeat 1). 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. 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. The pseudokinase domain
shows similarity to tyr kinases but lacks crucial
residues for catalytic activity and ATP binding. It
modulates the kinase activity of the C-terminal
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). 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.

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.

>gnl|CDD|198181 cd09927, SH2_Tensin_like, Src homology 2 domain found in
Tensin-like proteins. SH2 domain found in Tensin-like
proteins. The Tensins are a family of intracellular
proteins that interact with receptor tyrosine kinases
(RTKs), integrins, and actin. They are thought act as
signaling bridges between the extracellular space and
the cytoskeleton. There are four homologues: Tensin1,
Tensin2 (TENC1, C1-TEN), Tensin3 and Tensin4 (cten), all
of which contain a C-terminal tandem SH2-PTB domain
pairing, as well as actin-binding regions that may
localize them to focal adhesions. The isoforms of
Tensin2 and Tensin3 contain N-terminal C1 domains, which
are atypical and not expected to bind to phorbol esters.
Tensins 1-3 contain a phosphatase (PTPase) and C2 domain
pairing which resembles PTEN (phosphatase and tensin
homologue deleted on chromosome 10) protein. PTEN is a
lipid phosphatase that dephosphorylates
phosphatidylinositol 3,4,5-trisphosphate
(PtdIns(3,4,5)P3) to yield phosphatidylinositol
4,5-bisphosphate (PtdIns(4,5)P2). As PtdIns(3,4,5)P3 is
the product of phosphatidylinositol 3-kinase (PI3K)
activity, PTEN is therefore a key negative regulator of
the PI3K pathway. Because of their PTEN-like domains,
the Tensins may also possess phosphoinositide-binding or
phosphatase capabilities. However, only Tensin2 and
Tensin3 have the potential to be phosphatases since only
their PTPase domains contain a cysteine residue that is
essential for catalytic activity. In general SH2 domains
are involved in signal transduction. They typically bind
pTyr-containing ligands via two surface pockets, a pTyr
and hydrophobic binding pocket, allowing proteins with
SH2 domains to localize to tyrosine phosphorylated
sites.
