>gnl|CDD|238125 cd00204, ANK, ankyrin repeats; ankyrin repeats mediate
protein-protein interactions in very diverse families
of proteins. The number of ANK repeats in a protein can
range from 2 to over 20 (ankyrins, for example). ANK
repeats may occur in combinations with other types of
domains. The structural repeat unit contains two
antiparallel helices and a beta-hairpin, repeats are
stacked in a superhelical arrangement; this alignment
contains 4 consecutive repeats.

>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.

>gnl|CDD|173626 cd05034, PTKc_Src_like, Catalytic domain of Src kinase-like Protein
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.

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.

Tyrosine Kinases. Protein Tyrosine Kinase (PTK) family;
Fes subfamily; catalytic (c) domain. Fes subfamily
members include Fes (or Fps), Fer, 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

subfamily proteins are cytoplasmic (or nonreceptor) tyr
kinases containing an N-terminal region with FCH
(Fes/Fer/CIP4 homology) and coiled-coil domains,
followed by a SH2 domain, and a C-terminal catalytic
domain. The genes for Fes (feline sarcoma) and Fps
(Fujinami poultry sarcoma) were first isolated from
tumor-causing retroviruses. The viral oncogenes encode
chimeric Fes proteins consisting of Gag sequences at the
N-termini, resulting in unregulated tyr kinase activity.
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.

>gnl|CDD|173633 cd05052, PTKc_Abl, Catalytic domain of the Protein Tyrosine Kinase,
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.

>gnl|CDD|133165 cd05033, PTKc_EphR, Catalytic domain of Ephrin Receptor Protein
Tyrosine Kinases. Protein Tyrosine Kinase (PTK) family;
Ephrin Receptor (EphR) subfamily; 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). 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.

adaptors that link specific proteins to the
membrane-associated, spectrin- actin cytoskeleton. This
repeat-domain is a 'membrane-binding' domain of up to
24 repeated units, and it mediates most of the

especially active, with known sites of interaction for
the Na/K ATPase, Cl/HCO(3) anion exchanger,
voltage-gated sodium channel, clathrin heavy chain and

found to form a contiguous spiral stack such that ion
transporters like the anion exchanger associate in a
large central cavity formed by the ANK repeat spiral,
while clathrin and cell adhesion molecules associate
with specific regions outside this cavity.

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

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.

in Type I diabetes. It also regulates beta-cell number
during embryogenesis and early in life.

are receptor tyr kinases (RTKs) containing an
extracellular ligand-binding region with two
immunoglobulin-like domains followed by two fibronectin
type III repeats, a transmembrane segment, and an
intracellular catalytic domain. Binding to their
ligands, Gas6 and protein S, leads to receptor
dimerization, autophosphorylation, activation, and
intracellular signaling. Axl subfamily members are
implicated in a variety of cellular effects including
survival, proliferation, migration, and phagocytosis.
They are also associated with several types of cancer as
well as inflammatory, autoimmune, vascular, and kidney
diseases. Mer is named after its original reported
expression pattern (monocytes, epithelial, and
reproductive tissues). It is required for the ingestion
of apoptotic cells by phagocytes such as macrophages,
retinal pigment epithelial cells, and dendritic cells.
Mer is also important in maintaining immune homeostasis.

Tyrosine Kinases, Janus kinases. Protein Tyrosine
Kinase (PTK) family; Janus kinase (Jak) subfamily;
catalytic (c) domain (repeat 2). The Jak subfamily is
composed of Jak1, Jak2, Jak3, TYK2, 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.
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.

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.

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

neural differentiation in a manner independent of Src by
enhancing Mapk activation via Ras-mediated signaling.

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.

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. One exception is EphA4, which also
binds ephrins-B2/B3. 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. EphARs and ephrin-A
ligands are expressed in multiple areas of the
developing brain, especially in the retina and tectum.
They are part of a system controlling retinotectal

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

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

Tyrosine Kinase, Tyrosine kinase 2. Protein Tyrosine
Kinase (PTK) family; Tyrosine kinase 2 (Tyk2); 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. Tyk2 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 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.

includes the catalytic domains of other kinases such as
protein serine/threonine kinases, RIO kinases, and

receptor tyr kinase (RTK) containing an extracellular
region with two leucine-rich motifs, a transmembrane
segment, and an intracellular inactive pseudokinase
domain. The extracellular region of Ryk shows homology
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.

is composed of Tec, Btk, Bmx (Etk), Itk (Tsk, Emt), Rlk
(Txk), 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

(PI3K). PTKs catalyze the transfer of the
gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. Tec kinases are
cytoplasmic (or nonreceptor) tyr kinases (nRTKs) 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, some
members contain the Tec homology (TH) domain, which
contains proline-rich and zinc-binding 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
development, differentiation, maturation, regulation,
survival, and function of B-cells and T-cells. Mutations
in Btk cause the severe B-cell immunodeficiency,
X-linked agammaglobulinaemia (XLA).

The Aatyk subfamily is also referred to as the lemur

Aatyk proteins are mostly receptor tyr kinases (RTKs)

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
residues suggests that Aatyk proteins may be
multispecific kinases, functioning also as
serine/threonine kinases. They are involved in neural
differentiation, nerve growth factor (NGF) signaling,
apoptosis, and spermatogenesis.

Receptor (EGFR) subfamily; catalytic (c) domain. EGFR
(HER, ErbB) subfamily members include EGFR (HER1,
ErbB1), HER2 (ErbB2), HER3 (ErbB3), HER4 (ErbB4), and
similar proteins. The PTKc family is part of a larger
superfamily that includes the catalytic domains of other
kinases such as protein serine/threonine kinases, RIO
kinases, and phosphoinositide 3-kinase (PI3K). PTKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
The EGFR proteins are receptor tyr kinases (RTKs)
containing an extracellular EGF-related ligand-binding
region, a transmembrane helix, and a cytoplasmic region
with a tyr kinase domain and a regulatory C-terminal
tail. Unlike other tyr kinases, phosphorylation of the
activation loop of EGFR proteins is not critical to
their activation. Instead, they are activated by
ligand-induced dimerization, resulting in the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. Collectively, they can recognize a variety of
ligands including EGF, TGFalpha, and neuregulins, among
others. All four subfamily members can form homo- or
heterodimers. HER3 contains an impaired kinase domain
and depends on its heterodimerization partner for
activation. EGFR subfamily members are involved in
signaling pathways leading to a broad range of cellular
responses including cell proliferation, differentiation,
migration, growth inhibition, and apoptosis. Gain of
function alterations, through their overexpression,

Kinases, Bruton's tyrosine kinase and Bone marrow kinase
on the X chromosome. Protein Tyrosine Kinase (PTK)
family; Bruton's tyrosine kinase (Btk) and Bone marrow
kinase on the X chromosome (Bmx); 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. Btk and
Bmx (also named Etk) are members of the Tec subfamily of
proteins, which are cytoplasmic (or nonreceptor) tyr
kinases with similarity to Src kinases in that they
contain Src homology protein interaction domains (SH3,
SH2) N-terminal to the catalytic tyr kinase domain.
Unlike Src kinases, most Tec subfamily members (except
Rlk) also contain an N-terminal pleckstrin homology (PH)
domain, which binds the products of PI3K and allows
membrane recruitment and activation. In addition, Btk
contains the Tec homology (TH) domain with proline-rich
and zinc-binding regions. Tec kinases are expressed
mainly by haematopoietic cells. Btk is expressed in
B-cells, and a variety of myeloid cells including mast
cells, platelets, neutrophils, and dendrictic cells. It
interacts with a variety of partners, from cytosolic
proteins to nuclear transcription factors, suggesting a
diversity of functions. Stimulation of a diverse array
of cell surface receptors, including antigen engagement
of the B-cell receptor (BCR), leads to PH-mediated
membrane translocation of Btk and subsequent
phosphorylation by Src kinase and activation. Btk plays
an important role in the life cycle of B-cells including
their development, differentiation, proliferation,
survival, and apoptosis. Mutations in Btk cause the
primary immunodeficiency disease, X-linked
agammaglobulinaemia (XLA) in humans. Bmx is primarily
expressed in bone marrow and the arterial endothelium,
and plays an important role in ischemia-induced
angiogenesis. It facilitates arterial growth, capillary
formation, vessel maturation, and bone marrow-derived
endothelial progenitor cell mobilization.

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).

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.

protein. The Transient Receptor Potential Ca2+ Channel
(TRP-CC) Family (TC. 1.A.4)The TRP-CC family has also
been called the store-operated calcium channel (SOC)
family. The prototypical members include the Drosophila
retinal proteinsTRP and TRPL (Montell and Rubin, 1989;
Hardie and Minke, 1993). SOC members of the family
mediate the entry of extracellular Ca2+ into cells in
responseto depletion of intracellular Ca2+ stores
(Clapham, 1996) and agonist stimulated production of
inositol-1,4,5 trisphosphate (IP3). One member of the
TRP-CCfamily, mammalian Htrp3, has been shown to form a
tight complex with the IP3 receptor (TC #1.A.3.2.1).
This interaction is apparently required for IP3
tostimulate Ca2+ release via Htrp3. The vanilloid
receptor subtype 1 (VR1), which is the receptor for
capsaicin (the ?hot? ingredient in chili peppers) and
servesas a heat-activated ion channel in the pain
pathway (Caterina et al., 1997), is also a member of
this family. The stretch-inhibitable non-selective
cation channel(SIC) is identical to the vanilloid
receptor throughout all of its first 700 residues, but
it exhibits a different sequence in its last 100
residues. VR1 and SICtransport monovalent cations as
well as Ca2+. VR1 is about 10x more permeable to Ca2+
than to monovalent ions. Ca2+ overload probably causes
cell deathafter chronic exposure to capsaicin.

which are receptor tyr kinases (RTKs) containing an
extracellular EGF-related ligand-binding region, a
transmembrane helix, and a cytoplasmic region with a tyr
kinase domain and a regulatory C-terminal tail. Unlike
other tyr kinases, phosphorylation of the activation
loop of EGFR proteins is not critical to their
activation. Instead, they are activated by
ligand-induced dimerization, leading to the
phosphorylation of tyr residues in the C-terminal tail,
which serve as binding sites for downstream signaling
molecules. Ligands that bind HER4 fall into two groups,
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
signaling may contribute to schizophrenia.

catalyze the transfer of the gamma-phosphoryl group from
ATP to tyrosine (tyr) residues in protein substrates.
Hck 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. Hck is present in myeloid and lymphoid
cells that play a role in the development of cancer. It
may be important in the oncogenic signaling of the
protein Tel-Abl, which induces a chronic myelogenous
leukemia (CML)-like disease. Hck also acts as a negative
regulator of granulocyte colony-stimulating factor
(G-CSF)-induced proliferation of granulocytic
precursors, suggesting a possible role in the
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
(COPD).

Protein Tyrosine Kinase (PTK) family; Receptor tyrosine
kinase-like Orphan Receptor (Ror) subfamily; catalytic
(c) domain. The Ror subfamily consists of Ror1, Ror2,
and similar proteins. The PTKc family is part of a
larger superfamily that includes the catalytic domains
of other kinases such as protein serine/threonine
kinases, RIO kinases, and phosphoinositide 3-kinase
(PI3K). PTKs catalyze the transfer of the
gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. Ror proteins are orphan
receptor tyr kinases (RTKs) containing an extracellular
region with immunoglobulin-like, cysteine-rich, and
kringle domains, a transmembrane segment, and an
intracellular catalytic domain. Ror RTKs are unrelated
to the nuclear receptor subfamily called
retinoid-related orphan receptors (RORs). RTKs are
usually activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain. Ror kinases
are expressed in many tissues during development. They
play important roles in bone and heart formation.
Mutations in human Ror2 result in two different bone
development genetic disorders, recessive Robinow
syndrome and brachydactyly type B. Drosophila Ror is
expressed only in the developing nervous system during
neurite outgrowth and neuronal differentiation,
suggesting a role for Drosophila Ror in neural
development. More recently, mouse Ror1 and Ror2 have
also been found to play an important role in regulating
neurite growth in central neurons. Ror1 and Ror2 are
believed to have some overlapping and redundant
functions.

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.

interactions with six ephrin-A ligands. EphRs contain an
ephrin binding domain and two fibronectin repeats
extracellularly, a transmembrane segment, and a

ligand to EphR requires cell-cell contact since both are
anchored to the plasma membrane. The resulting
downstream signals occur bidirectionally in both

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

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.

activities, which initiate signaling cascades and
biological function. InsR and IGF-1R, which share 84%
sequence identity in their kinase domains, display
physiologically distinct yet overlapping functions in
cell growth, differentiation, and metabolism. InsR
activation leads primarily to metabolic effects while
IGF-1R activation stimulates mitogenic pathways. In

Unlike Src kinases, most Tec subfamily members (except
Rlk) also contain an N-terminal pleckstrin homology (PH)
domain, which binds the products of PI3K and allows
membrane recruitment and activation. Instead of PH, Rlk
contains an N-terminal cysteine-rich region. In addition
to PH, Tec also contains the Tec homology (TH) domain
with proline-rich and zinc-binding regions. Tec kinases
are expressed mainly by haematopoietic cells. Tec is
more widely-expressed than other Tec subfamily kinases.
It is found in endothelial cells, both B- and T-cells,
and a variety of myeloid cells including mast cells,
erythroid cells, platelets, macrophages and neutrophils.
Rlk is expressed in T-cells and mast cell lines. Tec and
Rlk are both key components of T-cell receptor (TCR)
signaling. They are important in TCR-stimulated
proliferation, IL-2 production and phopholipase C-gamma1
activation.

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

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

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.

there is no evidence to suggest that agrin binds
directly to Musk. Mutations in AChR, Musk and other

as the autoimmune syndrome myasthenia gravis.

Tyrosine Kinase (PTK) family; Fibroblast Growth Factor

FGFR subfamily consists of FGFR1, FGFR2, FGFR3, FGFR4,
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. FGFR subfamily members
are receptor tyr kinases (RTKs) containing an
extracellular ligand-binding region with three
immunoglobulin-like domains, a transmembrane segment,
and an intracellular catalytic domain. The binding of
FGFRs to their ligands, the FGFs, and to heparin/heparan
sulfate (HS) results in the formation of a ternary
complex, which leads to receptor dimerization and
activation, and intracellular signaling. There are at
least 23 FGFs and four types of FGFRs. 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. FGF/FGFR signaling is
important in the regulation of embryonic development,
homeostasis, and regenerative processes. Depending on
the cell type and stage, FGFR signaling produces diverse
cellular responses including proliferation, growth
arrest, differentiation, and apoptosis. Aberrant
signaling leads to many human diseases such as skeletal,
olfactory, and metabolic disorders, as well as cancer.

sensory and sympathetic neurons of the peripheral
nervous system, and in basal forebrain cholinergic
neurons of the central nervous system. It is critical
for neuronal growth, differentiation and survival.
Alternative TrkA splicing has been implicated as a
pivotal regulator of neuroblastoma (NB) behavior. Normal
TrkA expression is associated with better NB prognosis,
while the hypoxia-regulated TrkAIII splice variant
promotes NB pathogenesis and progression. Aberrant TrkA
expression has also been demonstrated in non-neural
tumors including prostate, breast, lung, and pancreatic
cancers.

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 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

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. A mutation which results in a
truncation of a C-terminal part of the human STRAD-alpha
pseudokinase domain and disrupts its association with
LKB1, leads to PMSE (polyhydramnios, megalencephaly,
symptomatic epilepsy) syndrome. Several splice variants
of STRAD-alpha exist which exhibit different effects on
the localization and activation of LKB1.

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.

>gnl|CDD|187661 cd08958, FR_SDR_e, flavonoid reductase (FR), extended (e) SDRs.
This subgroup contains FRs of the extended SDR-type and
related proteins. These FRs act in the NADP-dependent
reduction of flavonoids, ketone-containing plant
secondary metabolites; they have the characteristic
active site triad of the SDRs (though not the upstream
active site Asn) and a NADP-binding motif that is very
similar to the typical extended SDR motif. Extended
SDRs are distinct from classical SDRs. In addition to
the Rossmann fold (alpha/beta folding pattern with a
central beta-sheet) core region typical of all SDRs,
extended SDRs have a less conserved C-terminal
extension of approximately 100 amino acids. Extended
SDRs are a diverse collection of proteins, and include
isomerases, epimerases, oxidoreductases, and lyases;
they typically have a TGXXGXXG cofactor binding motif.
SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold, an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Sequence identity between different
SDR enzymes is typically in the 15-30% range; they
catalyze a wide range of activities including the
metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving
as a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase numbering). In
addition to the Tyr and Lys, there is often an upstream
Ser and/or an Asn, contributing to the active site;
while substrate binding is in the C-terminal region,
which determines specificity. The standard reaction
mechanism is a 4-pro-S hydride transfer and proton
relay involving the conserved Tyr and Lys, a water
molecule stabilized by Asn, and nicotinamide. Atypical
SDRs generally lack the catalytic residues
characteristic of the SDRs, and their glycine-rich
NAD(P)-binding motif is often different from the forms
normally seen in classical or extended SDRs. Complex
(multidomain) SDRs such as ketoreductase domains of
fatty acid synthase have a GGXGXXG NAD(P)-binding motif
and an altered active site motif (YXXXN). Fungal type
ketoacyl reductases have a TGXXXGX(1-2)G NAD(P)-binding
motif.

dual-specificity MAP kinase kinases. Protein kinases
(PKs), MAP kinase kinase (MAPKK) subfamily, fungal
Byr1-like proteins, catalytic (c) domain. PKs catalyze
the transfer of the gamma-phosphoryl group from ATP to
serine/threonine or tyrosine residues on protein
substrates. The MAPKK subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein serine/threonine kinases, protein tyrosine
kinases, RIO kinases, aminoglycoside phosphotransferase,
choline kinase, and phosphoinositide 3-kinase. The
mitogen-activated protein (MAP) kinase signaling
pathways are important mediators of cellular responses
to extracellular signals. The pathways involve a triple
kinase core cascade comprising 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.

this subgroup have a complete SDR-type active site
tetrad and a close match to the canonical extended SDR
NADP-binding motif. Aldehyde reductase I (aka carbonyl
reductase) is an NADP-binding SDR; it catalyzes the

Tyrosine Kinase (PTK) family; Fibroblast Growth Factor
Receptor 4 (FGFR4); 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. FGFR4 is
part of the FGFR subfamily, which are receptor tyr
kinases (RTKs) containing an extracellular
ligand-binding region with three immunoglobulin-like
domains, a transmembrane segment, and an intracellular
catalytic domain. The binding of FGFRs to their ligands,
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. Unlike other FGFRs,
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
regulation of muscle regeneration. A polymorphism in
FGFR4 is found in head and neck squamous cell carcinoma.

chromosome alignment and splitting during mitosis. It
interacts with the gamma-tubulin ring complex and the
Ran GTPase, and is implicated in microtubule
organization. Nek9 associates with FACT (FAcilitates
Chromatin Transcription) and modulates interphase
progression. It also interacts with Nek6, and Nek7,
during mitosis, resulting in their activation.

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.
