>gnl|CDD|173670 cd05579, STKc_MAST_like, Catalytic domain of Microtubule-associated
serine/threonine kinase-like proteins. Serine/Threonine
Kinases (STKs), Microtubule-associated serine/threonine
(MAST) kinase subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The MAST kinase 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. The MAST kinase subfamily
includes MAST kinases, MAST-like (MASTL) kinases, and
fungal kinases with similarity to Saccharomyces
cerevisiae Rim15 and Schizosaccharomyces pombe cek1.
MAST kinases contain an N-terminal domain of unknown
function, a central catalytic domain, and a C-terminal
PDZ domain that mediates protein-protein interactions.
MASTL kinases carry only a catalytic domain which
contains a long insert relative to other kinases. The
fungal kinases in this subfamily harbor other domains in
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.

>gnl|CDD|173660 cd05123, STKc_AGC, Catalytic domain of AGC family Protein
Serine/Threonine Kinases. Serine/Threonine Kinases
(STKs), AGC (Protein Kinases A, G and C) family,
catalytic (c) domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The AGC family is part
of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and Phosphoinositide 3-Kinase (PI3K). Members of
this family include cAMP-dependent Protein Kinase (PKA),
cGMP-dependent Protein Kinase (PKG), Protein Kinase C
(PKC), Protein Kinase B (PKB), G protein-coupled
Receptor Kinase (GRK), Serum- and Glucocorticoid-induced
Kinase (SGK), and 70 kDa ribosomal Protein S6 Kinase
(p70S6K or S6K), among others. AGC kinases share an
activation mechanism based on the phosphorylation of up
to three sites: the activation loop (A-loop), the
hydrophobic motif (HM) and the turn motif.
Phosphorylation at the A-loop is required of most AGC
kinases, which results in a disorder-to-order transition
of the A-loop. The ordered conformation results in the
access of substrates and ATP to the active site. A
subset of AGC kinases with C-terminal extensions
containing the HM also requires phosphorylation at this
site. Phosphorylation at the HM allows the C-terminal
extension to form an ordered structure that packs into
the hydrophobic pocket of the catalytic domain, which
then reconfigures the kinase into an active bi-lobed
state. In addition, growth factor-activated AGC kinases
such as PKB, p70S6K, RSK, MSK, PKC, and SGK, require
phosphorylation at the turn motif (also called tail or
zipper site), located N-terminal to the HM at the
C-terminal extension. AGC kinases regulate many cellular
processes including division, growth, survival,
metabolism, motility, and differentiation. Many are
implicated in the development of various human diseases.

RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase (PI3K). PDK1
carries an N-terminal catalytic domain and a C-terminal
pleckstrin homology (PH) domain that binds
phosphoinositides. It phosphorylates the activation loop
of AGC kinases that are regulated by PI3K such as PKB,
SGK, and PKC, among others, and is crucial for their
activation. Thus, it contributes in regulating many
processes including metabolism, growth, proliferation,
and survival. PDK1 also has the ability to
autophosphorylate and is constitutively active in
mammalian cells. PDK1 is essential for normal embryo
development and is important in regulating cell volume.

>gnl|CDD|173665 cd05574, STKc_phototropin_like, Catalytic domain of
Phototropin-like Protein Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Phototropin-like
subfamily, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
phototropin-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. Included in this subfamily
are plant phototropins and predominantly uncharacterized
fungal STKs whose catalytic domains resemble the
phototropin kinase domain. One protein from Neurospora
crassa is called nrc-2. Phototropins are blue-light
receptors that control responses such as phototropism,
stromatal opening, and chloroplast movement in order to
optimize the photosynthetic efficiency of plants. They
are light-activated STKs that contain an N-terminal
photosensory domain and a C-terminal catalytic domain.
The N-terminal domain contains two LOV (Light, Oxygen or
Voltage) domains that binds FMN. Photoexcitation of the
LOV domains results in autophosphorylation at multiple
sites and activation of the catalytic domain. Neurospora
crassa nrc-2 plays a role in growth and development by
controlling entry into the conidiation program.

Serine/Threonine Kinases (STKs), Never In Mitosis gene A
(NIMA)-related kinase (Nek) family, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The Nek family is part
of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. The Nek family is
composed of 11 different mammalian members (Nek1-11)
with similarity to the catalytic domain of Aspergillus
nidulans NIMA kinase, the founding member of the Nek
family which was identified in a screen for cell cycle
mutants that were prevented from entering mitosis. Neks
contain a conserved N-terminal catalytic domain and a
more divergent C-terminal regulatory region of various
sizes and structures. They are involved in the
regulation of downstream processes following the
activation of Cdc2, and many of their functions are cell
cycle-related. They play critical roles in microtubule
dynamics during ciliogenesis and mitosis.

subfamily is part of a larger superfamily that includes
the catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase (PI3K). This subfamily is composed of the
cAMP-dependent proteins kinases, PKA and PRKX. The
inactive PKA holoenzyme is a heterotetramer composed of
two phosphorylated and active catalytic (C) subunits
with a dimer of regulatory (R) subunits. Activation is
achieved through the binding of the important second
messenger cAMP to the R subunits, which leads to the
dissociation of PKA into the R dimer and two active C
subunits. PKA is present ubiquitously in cells and
interacts with many different downstream targets. It
plays a role in the regulation of diverse processes such
as growth, development, memory, metabolism, gene
expression, immunity, and lipolysis.

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

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

classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
structural characteristics of their regulatory domain.
PKCs undergo three phosphorylations in order to take
mature forms. In addition, classical PKCs depend on
calcium, DAG (1,2-diacylglycerol), and in most cases,
phosphatidylserine (PS) for activation. Novel PKCs are
calcium-independent, but require DAG and PS for
activity, while atypical PKCs only require PS. PKCs
phosphorylate and modify the activities of a wide
variety of cellular proteins including receptors,
enzymes, cytoskeletal proteins, transcription factors,
and other kinases. They play a central role in signal
transduction pathways that regulate cell migration and
polarity, proliferation, differentiation, and apoptosis.
Also included in this subfamily are the PKC-like
proteins, called PKNs.

including adaptor/regulatory modules in signal
transduction, pre-mRNA processing and cytoskeleton
assembly; typically contains a GH dipeptide 11-24
residues from its N-terminus and the WD dipeptide at its
C-terminus and is 40 residues long, hence the name WD40;
between GH and WD lies a conserved core; serves as a
stable propeller-like platform to which proteins can
bind either stably or reversibly; forms a propeller-like
structure with several blades where each blade is
composed of a four-stranded anti-parallel b-sheet;
instances with few detectable copies are hypothesized to
form larger structures by dimerization; each WD40
sequence repeat forms the first three strands of one
blade and the last strand in the next blade; the last
C-terminal WD40 repeat completes the blade structure of
the first WD40 repeat to create the closed ring
propeller-structure; residues on the top and bottom
surface of the propeller are proposed to coordinate
interactions with other proteins and/or small ligands; 7
copies of the repeat are present in this alignment.

protein kinase-like Protein Serine/Threonine Kinases.
Serine/Threonine Kinases (STKs), Myotonic Dystrophy
protein kinase (DMPK)-like subfamily, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The DMPK-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. The DMPK-like subfamily is composed of DMPK
and DMPK-related cell division control protein 42
(Cdc42) binding kinase (MRCK). Three isoforms of MRCK
are known, named alpha, beta and gamma. The DMPK gene is
implicated in myotonic dystrophy 1 (DM1), an inherited
multisystemic disorder with symptoms that include muscle
hyperexcitability, progressive muscle weakness and
wasting, cataract development, testicular atrophy, and
cardiac conduction defects. The genetic basis for DM1 is
the mutational expansion of a CTG repeat in the 3'-UTR
of DMPK. DMPK is expressed in skeletal and cardiac
muscles, and in central nervous tissues. The functional
role of DMPK is not fully understood. It may play a role
in the signal transduction and homeostasis of calcium.
MRCK is activated via interaction with the small GTPase
Cdc42. MRCK/Cdc42 signaling mediates myosin-dependent
cell motility. MRCKgamma is expressed in heart and
skeletal muscles, unlike MRCKalpha and MRCKbeta, which
are expressed ubiquitously.

founding member of the Nek family, which was identified
in a screen for cell cycle mutants prevented from
entering mitosis. NIMA is essential for mitotic entry
and progression through mitosis, and its degradation is
essential for mitotic exit. NIMA is involved in nuclear
membrane fission. Vertebrate Nek2 is a cell
cycle-regulated STK, localized in centrosomes and
kinetochores, that regulates centrosome splitting at the
G2/M phase. It also interacts with other mitotic kinases
such as Polo-like kinase 1 and may play a role in
spindle checkpoint. An increase in the expression of the
human NEK2 gene is strongly associated with the
progression of non-Hodgkin lymphoma.

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

downstream targets. MSK1 plays a role in the regulation
of translational control and transcriptional activation.
It phosphorylates the transcription factors, CREB and

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

3-kinase. NDR kinase contains an N-terminal regulatory
(NTR) domain and an insert within the catalytic domain
that contains an auto-inhibitory sequence. Like many
other AGC kinases, NDR kinase requires phosphorylation
at two sites, the activation loop (A-loop) and the
hydrophobic motif (HM), for activity. NDR kinases
regulate mitosis, cell growth, embryonic development,
and neurological processes. They are also required for
proper centrosome duplication. Higher eukaryotes contain
two NDR isoforms, NDR1 and NDR2. This subfamily also
contains fungal NDR-like kinases.

ASK2, and MAPKKK15. MAPKKKs phosphorylate and activate
MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn
phosphorylate and activate MAPKs during signaling
cascades that are important in mediating cellular
responses to extracellular signals. ASK1 (also called
MAPKKK5) functions in the c-Jun N-terminal kinase (JNK)

their respective MAPKKs, MKK4/MKK7 and MKK3/MKK6. It
plays important roles in cytokine and stress responses,
as well as in reactive oxygen species (ROS)-mediated
cellular responses. ASK1 is implicated in various
diseases mediated by oxidative stress including
inschemic heart disease, hypertension, vessel injury,
brain ischemia, Fanconi anemia, asthma, and pulmonary

PAK1 belongs to group I. Group I PAKs contain a PBD
(p21-binding domain) overlapping with an AID
(autoinhibitory domain), a C-terminal catalytic domain,
SH3 binding sites and a non-classical SH3 binding site
for PIX (PAK-interacting exchange factor). PAK1 is
important in the regulation of many cellular processes
including cytoskeletal dynamics, cell motility, growth,
and proliferation. Although PAK1 has been regarded
mainly as a cytosolic protein, recent reports indicate
that PAK1 also exists in significant amounts in the
nucleus, where it is involved in transcription
modulation and in cell cycle regulatory events. PAK1 is
also involved in transformation and tumorigenesis. Its
overexpression, hyperactivation and increased nuclear
accumulation is correlated to breast cancer invasiveness
and progression. Nuclear accumulation is also linked to
tamoxifen resistance in breast cancer cells.

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

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

that contains an auto-inhibitory sequence. Like many
other AGC kinases, NDR kinase requires phosphorylation
at two sites, the activation loop (A-loop) and the
hydrophobic motif (HM), for activity. Higher eukaryotes
contain two NDR isoforms, NDR1 and NDR2. Both isoforms
play a role in proper centrosome duplication. In
addition, NDR2 plays a role in regulating neuronal
growth and differentiation, as well as in facilitating
neurite outgrowth. It is also implicated in fear
conditioning as it contributes to the coupling of
neuronal morphological changes with fear-memory
consolidation. NDR2 is also referred to as STK38-like.

PKB-alpha exhibit perinatal morbidity, growth
retardation, reduction in body weight accompanied by
reduced sizes of multiple organs, and enhanced apoptosis
in some cell types. PKB-alpha activity has been reported
to be frequently elevated in breast and prostate

activated by caspases leading to morphological changes
during apoptosis. PAK2 is also activated in response to
a variety of stresses including DNA damage,
hyperosmolarity, serum starvation, and contact

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

phosphoinositide 3-kinase. Mammals have two cGK isoforms
from different genes, cGKI and cGKII. cGKI exists as two
splice variants, cGKI-alpha and cGKI-beta. cGK consists
of an N-terminal regulatory domain containing a
dimerization and an autoinhibitory pseudosubstrate
region, two cGMP-binding domains, and a C-terminal
catalytic domain. Binding of cGMP to both binding sites
releases the inhibition of the catalytic center by the
pseudosubstrate region, allowing autophosphorylation and
activation of the kinase. cGKI is a soluble protein
expressed in all smooth muscles, platelets, cerebellum,
and kidney. It is also expressed at lower concentrations
in other tissues. cGKII is a membrane-bound protein that
is most abundantly expressed in the intestine. It is
also present in the brain nuclei, adrenal cortex,
kidney, lung, and prostate. cGKI is involved in the
regulation of smooth muscle tone, smooth cell
proliferation, and platelet activation. cGKII plays a
role in the regulation of secretion, such as renin
secretion by the kidney and aldosterone secretion by the
adrenal. It also regulates bone growth and the circadian
rhythm.

Serine/Threonine Kinases (STKs), Novel Protein Kinase C
(nPKC), delta isoform, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The nPKC subfamily is part of a larger superfamily that
includes the catalytic domains of other protein STKs,
protein tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PKCs are classified into three groups
(classical, atypical, and novel) depending on their mode
of activation and the structural characteristics of
their regulatory domain. nPKCs are calcium-independent,
but require DAG (1,2-diacylglycerol) and
phosphatidylserine (PS) for activity. There are four
nPKC isoforms, delta, epsilon, eta, and theta. PKC-delta
plays a role in cell cycle regulation and programmed
cell death in many cell types. It slows down cell
proliferation, inducing cell cycle arrest and enhancing
cell differentiation. PKC-delta is also involved in the
regulation of transcription as well as immune and
inflammatory responses. It plays a central role in the
genotoxic stress response that leads to DNA
damaged-induced apoptosis.

phosphorylates and activates the MAPK kinase MEK5 (or
MKK5), which in turn phosphorylates and activates
extracellular signal-regulated kinase 5 (ERK5). The ERK5
cascade plays roles in promoting cell proliferation,
differentiation, neuronal survival, and neuroprotection.
MEKK3 plays an essential role in embryonic angiogenesis
and early heart development. In addition, MEKK3 is
involved in interleukin-1 receptor and Toll-like

(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.

PAKs interact with the SH3 containing proteins Nck, Grb2
and PIX, no such binding has been demonstrated for group
II PAKs. Some known substrates of group II PAKs are also
substrates of group I PAKs such as Raf, BAD, LIMK and

(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,

ligand-binding domain, a transmembrane region, and an
intracellular tyr kinase domain. They are usually
activated through ligand binding, which causes
dimerization and autophosphorylation of the
intracellular tyr kinase catalytic domain. ALK appears
to play an important role in mammalian neural
development as well as visceral muscle differentiation
in Drosophila. ALK is aberrantly expressed as fusion
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
expressing TLK display retarded growth and high
mortality rate. In addition, a polymorphism in mouse and
human LTK is implicated in the pathogenesis of systemic
lupus erythematosus.

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

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

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).

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). 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.

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.

activated by a MAPK kinase kinase (MAPKKK or MKKK).

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

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.

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

neurons to muscle cells. Agrin, a large proteoglycan
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

involved in the control of cell-cycle progression,
transcription, and neuronal function. CDK4 and CDK6
partner with D-type cyclins to regulate the early G1
phase of the cell cycle. They are the first kinase
activated by mitogenic signals to release cells from the
G0 arrested state. CDK4 and CDK6 are both expressed
ubiquitously, associate with all three D cyclins (D1, D2
and D3), and phosphorylate the retinoblastoma (pRb)
protein. They are also regulated by the INK4 family of
inhibitors which associate with either the CDK alone or
the CDK/cyclin complex. CDK4 and CDK6 show differences
in subcellular localization, sensitivity to some
inhibitors, timing in activation, tumor selectivity, and
possibly substrate profiles. Although CDK4 and CDK6 seem
to show some redundancy, they also have discrete,
nonoverlapping functions. CDK6 plays an important role
in cell differentiation.

despite the presence of activating ligand. There are
seven types of GRKs, named GRK1 to GRK7. The beta-ARK
group is composed of GRK2, GRK3, and similar proteins.
GRK2 and GRK3 are both widely expressed in many tissues,
although GRK2 is present at higher levels. They contain
an N-terminal RGS homology (RH) domain, a central
catalytic domain, and C-terminal pleckstrin homology
(PH) domain that mediates PIP2 and G protein
betagamma-subunit translocation to the membrane. GRK2
(also called beta-ARK or beta-ARK1) is important in
regulating several cardiac receptor responses. It plays
a role in cardiac development and in hypertension.
Deletion of GRK2 in mice results in embryonic lethality,
caused by hypoplasia of the ventricular myocardium. GRK2
also plays important roles in the liver (as a regulator

reported in several disorders including major
depression, schizophrenia, bipolar disorder, and

a triple kinase core cascade comprising the MAP kinase
(MAPK), which is phosphorylated and activated by a MAPK
kinase (MAPKK or MKK), which itself is phosphorylated
and activated by a MAPK kinase kinase (MAPKKK or MKKK).
MKK7 is a dual-specificity PK that phosphorylates and
activates its downstream target, c-Jun N-terminal kinase
(JNK), on specific threonine and tyrosine residues.
Although MKK7 is capable of dual phosphorylation, it
prefers to phosphorylate the threonine residue of JNK.
Thus, optimal activation of JNK requires both MKK4 (not
included in this subfamily) and MKK7. MKK7 is primarily
activated by cytokines. MKK7 is essential for liver
formation during embryogenesis. It plays roles in G2/M
cell cycle arrest and cell growth. In addition, it is
involved in the control of programmed cell death, which
is crucial in oncogenesis, cancer chemoresistance, and
antagonism to TNFalpha-induced killing, through its
inhibition by Gadd45beta and the subsequent suppression
of the JNK cascade.

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

small GTP-binding protein or by an adaptor protein,
which transmits the signal either directly to a MAP3K to

through a mediator kinase, a MAP4K. There are three main
typical MAPK subfamilies: Extracellular signal-Regulated

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.

essential for neural development. Mouse embryos
containing a truncated CCK4 die perinatally and display
craniorachischisis, a severe form of neural tube defect.
The mechanism of action of the CCK4 pseudokinase is
still unknown. Other pseudokinases such as HER3 rely on
the activity of partner RTKs.

Ime2p, Schizosaccharomyces pombe Mei4-dependent protein
3 (Mde3) and Pit1, Caenorhabditis elegans dyf-5,
Arabidopsis thaliana MHK, and similar proteins. These
proteins play important roles during meiosis. MAK is
highly expressed in testicular cells specifically in the
meiotic phase, but is not essential for spermatogenesis
and fertility. It functions as a coactivator of the
androgen receptor in prostate cells. MRK, also called
Intestinal Cell Kinase (ICK), is expressed ubiquitously,
with highest expression in the ovary and uterus. A
missense mutation in MRK causes
endocrine-cerebro-osteodysplasia (ECO), suggesting that
this protein plays an important role in the development
of many organs. MAK and MRK may be involved in
regulating cell cycle and cell fate. Ime2p is a
meiosis-specific kinase that is important during meiotic
initiation and during the later stages of meiosis. Mde3
functions downstream of the transcription factor Mei-4
which is essential for meiotic prophase I.

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.

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.

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.

tyrosine kinase). Protein Tyrosine Kinase (PTK) family;
Receptor related to tyrosine kinase (Ryk); pseudokinase
domain. The PTKc (catalytic domain) family to which this
subfamily belongs, is part of a larger superfamily that
includes the catalytic domains of other kinases such as
protein serine/threonine kinases, RIO kinases, and
phosphoinositide 3-kinase (PI3K). PTKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
tyrosine (tyr) residues in protein substrates. Ryk is a
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.

VEGFR2 (or Flk1) is a member of the VEGFR subfamily of
proteins, which are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
seven immunoglobulin (Ig)-like domains, a transmembrane
segment, and an intracellular catalytic domain. The
binding of VEGFRs to their ligands, the VEGFs, leads to
receptor dimerization, activation, and intracellular
signaling. The carboxyl terminus of VEGFR2 plays an
important role in its autophosphorylation and
activation. VEGFR2 binds the ligands VEGFA, VEGFC, VEGFD
and VEGFE. VEGFR2 signaling is implicated in all aspects
of normal and pathological vascular endothelial cell
biology. It induces a variety of cellular effects
including migration, survival, and proliferation. It is
critical in regulating embryonic vascular development
and angiogenesis. VEGFR2 is the major signal transducer
in pathological angiogenesis including cancer and
diabetic retinopathy, and is a target for inhibition in
cancer therapy.

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

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.

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.

Protein Tyrosine Kinase (PTK) family; Vascular
Endothelial Growth Factor Receptor 3 (VEGFR3); 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.
VEGFR3 (or Flt4) is a member of the VEGFR subfamily of
proteins, which are receptor tyr kinases (RTKs)
containing an extracellular ligand-binding region with
seven immunoglobulin (Ig)-like domains, a transmembrane
segment, and an intracellular catalytic domain. In
VEGFR3, the fifth Ig-like domain is replaced by a
disulfide bridge. The binding of VEGFRs to their
ligands, the VEGFs, leads to receptor dimerization,
activation, and intracellular signaling. VEGFR3
preferentially binds the ligands VEGFC and VEGFD. VEGFR3
is essential for lymphatic endothelial cell (EC)
development and function. It has been shown to regulate
adaptive immunity during corneal transplantation. VEGFR3
is upregulated on blood vascular ECs in pathological
conditions such as vascular tumors and the periphery of
solid tumors. It plays a role in cancer progression and
lymph node metastasis. Missense mutations in the VEGFR3
gene are associated with primary human lymphedema.

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.

kinase kinase 4 (MKK4) subfamily, catalytic (c) domain.
PKs catalyze the transfer of the gamma-phosphoryl group
from ATP to serine/threonine or tyrosine residues on
protein substrates. The MKK4 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). MKK4 is a dual-specificity PK that
phosphorylates and activates the downstream targets,
c-Jun N-terminal kinase (JNK) and p38 MAPK, on specific
threonine and tyrosine residues. JNK and p38 are
collectively known as stress-activated MAPKs, as they
are activated in response to a variety of environmental
stresses and pro-inflammatory cytokines. Their
activation is associated with the induction of cell
death. Mice deficient in MKK4 die during embryogenesis
and display anemia, severe liver hemorrhage, and
abnormal hepatogenesis. MKK4 may also play roles in the
immune system and in cardiac hypertrophy. It plays a
major role in cancer as a tumor and metastasis
suppressor. Under certain conditions, MKK4 is
pro-oncogenic.

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

receptor tyr kinase (RTK) that is composed of two
alphabeta heterodimers. Binding of the insulin ligand to
the extracellular alpha subunit activates the
intracellular tyr kinase domain of the transmembrane
beta subunit. Receptor activation leads to
autophosphorylation, stimulating downstream kinase
activities, which initiate signaling cascades and
biological function. InsR signaling plays an important
role in many cellular processes including glucose
homeostasis, glycogen synthesis, lipid and protein
metabolism, ion and amino acid transport, cell cycle and
proliferation, cell differentiation, gene transcription,
and nitric oxide synthesis. Insulin resistance, caused
by abnormalities in InsR signaling, has been described
in diabetes, hypertension, cardiovascular disease,
metabolic syndrome, heart failure, and female
infertility.

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. 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.
