>gnl|CDD|173725 cd06608, STKc_myosinIII_like, Catalytic domain of Class III
myosin-like Protein Serine/Threonine Kinases.
Serine/threonine kinases (STKs), Class III myosin-like
subfamily, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The
class III myosin-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. Class III myosins are motor
proteins with an N-terminal kinase catalytic domain and
a C-terminal actin-binding motor domain. Class III
myosins are present in the photoreceptors of
invertebrates and vertebrates and in the auditory hair
cells of mammals. The kinase domain of myosin III can
phosphorylate several cytoskeletal proteins,
conventional myosin regulatory light chains, and can
autophosphorylate the C-terminal motor domain. Myosin
III may play an important role in maintaining the
structural integrity of photoreceptor cell microvilli.
It may also function as a cargo carrier during
light-dependent translocation, in photoreceptor cells,
of proteins such as transducin and arrestin. The
Drosophila class III myosin, called NinaC (Neither
inactivation nor afterpotential protein C), is critical
in normal adaptation and termination of photoresponse.
Vertebrates contain two isoforms of class III myosin,
IIIA and IIIB. This subfamily also includes mammalian
NIK-like embryo-specific kinase (NESK), Traf2- and
Nck-interacting kinase (TNIK), mitogen-activated protein
kinase (MAPK) kinase kinase kinase 4 (MAPKKKK4 or
MAP4K4) and MAPKKKK6 (or MAP4K6). MAP4Ks are involved in
some MAPK signaling pathways by activating a MAPK kinase
kinase (MAPKKK or MAP3K or MKKK). Each MAPK cascade is
activated either by a small GTP-binding protein or by an
adaptor protein, which transmits the signal either
directly to a MAP3K to start the triple kinase core
cascade or indirectly through a mediator kinase, a
MAP4K. MAPK signaling cascades are important in
mediating cellular responses to extracellular signals.

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

kinases (STKs), mitogen-activated protein kinase (MAPK)
kinase kinase kinase 4 (MAPKKKK4 or MAP4K4) and MAPKKKK6
(or MAP4K6) subfamily, catalytic (c) domain. STKs
catalyze the transfer of the gamma-phosphoryl group from
ATP to serine/threonine residues on protein substrates.
The MAP4K4/MAP4K6 subfamily is part of a larger
superfamily that includes the catalytic domains of other
protein STKs, protein tyrosine kinases, RIO kinases,
aminoglycoside phosphotransferase, choline kinase, and
phosphoinositide 3-kinase. Members of this subfamily
contain an N-terminal catalytic domain and a C-terminal

MAPKKKKs) are involved in MAPK signaling pathways that
are important in mediating cellular responses to
extracellular signals by activating a MAPK kinase kinase

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

In photoreceptor cells, they may also function as cargo
carriers during light-dependent translocation of
proteins such as transducin and arrestin. Class IIIA
myosin is highly expressed in retina and in inner ear
hair cells. It is localized to the distal ends of
actin-bundled structures. Mutations in human myosin IIIA
are responsible for progressive nonsyndromic hearing
loss. Human myosin IIIA possesses ATPase and kinase
activities, and the ability to move actin filaments in a
motility assay. It may function as a cellular
transporter capable of moving along actin bundles in
sensory cells.

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

family GTPase-regulated kinases that serve as important
mediators in the function of Cdc42 (cell division cycle
42) and Rac. PAKs are implicated in the regulation of
many cellular processes including growth factor
receptor-mediated proliferation, cell polarity, cell
motility, cell death and survival, and actin
cytoskeleton organization. PAK deregulation is
associated with tumor development. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
Group I PAKs contain a PBD (p21-binding domain)
overlapping with an AID (autoinhibitory domain), a
C-terminal catalytic domain, SH3 binding sites and a
non-classical SH3 binding site for PIX (PAK-interacting
exchange factor). Group II PAKs contain a PBD and a
catalytic domain, but lack other motifs found in group I
PAKs. Since group II PAKs do not contain an obvious AID,
they may be regulated differently from group I PAKs.
Group I PAKs interact with the SH3 containing proteins
Nck, Grb2 and PIX; no such binding has been demonstrated
for group II PAKs.

kinase kinase 3 (MAPKKKK3 or MAP4K3) subfamily,

part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. Members of this
subfamily contain an N-terminal catalytic domain and a
C-terminal citron homology (CNH) regulatory domain,
similar to MAP4K4/6. MAP4Ks are involved in some MAPK
signaling pathways that are important in mediating
cellular responses to extracellular signals by
activating a MAPK kinase kinase (MAPKKK or MAP3K or
MKKK). Each MAPK cascade is activated either by a small
GTP-binding protein or by an adaptor protein, which
transmits the signal either directly to a MAP3K to start
the triple kinase core cascade or indirectly through a
mediator kinase, a MAP4K. MAP4K3 plays a role in the
nutrient-responsive pathway of mTOR (mammalian target of
rapamycin) signaling. MAP4K3 is required in the
activation of S6 kinase by amino acids and for the
phosphorylation of the mTOR-regulated inhibitor of
eukaryotic initiation factor 4E. mTOR regulates ribosome
biogenesis and protein translation, and is frequently
deregulated in cancer.

of the gamma-phosphoryl group from ATP to

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.

(BMK1) or MAPK7, has a unique C-terminal extension,
making it approximately twice as big as other MAPKs.
This extension contains transcriptional activation
capability which is inhibited by the N-terminal half.
ERK5 is activated in response to growth factors and
stress by a cascade that leads to its phosphorylation by
the MAP2K MEK5, which in turn is regulated by the MAP3Ks
MEKK2 and MEKK3. Activated ERK5 phosphorylates its
targets including myocyte enhancer factor 2 (MEF2),
Sap1a, c-Myc, and RSK. It plays a role in EGF-induced
cell proliferation during the G1/S phase transition.
Studies on knockout mice revealed that ERK5 is essential
for cardiovascular development and plays an important
role in angiogenesis. It is also critical for neural
differentiation and survival. The ERK5 pathway has been
implicated in the pathogenesis of many diseases
including cancer, cardiac hypertrophy, and
atherosclerosis.

Schizosaccharomyces pombe Byr2, Saccharomyces cerevisiae
and Cryptococcus neoformans Ste11, and related proteins.
They contain an N-terminal SAM (sterile alpha-motif)
domain, which mediates protein-protein interaction, and
a C-terminal catalytic domain. 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. Fission
yeast Byr2 is regulated by Ras1. It responds to
pheromone signaling and controls mating through the MAPK
pathway. Budding yeast Ste11 functions in MAPK cascades
that regulate mating, high osmolarity glycerol, and
filamentous growth responses.

physiological, developmental, hormonal, and stress
responses. Some plants show numerous gene duplications
of MAPKs. Arabidopsis thaliana harbors at least 20
MAPKs, named AtMPK1-20. Oryza sativa contains at least
17 MAPKs. There are two subtypes of plant MAPKs based
on the conserved phosphorylation motif present in the
activation loop, TEY and TDY. Arabidopsis thaliana
contains more TEY-type MAPKs than TDY-type, whereas the
reverse is true for Oryza sativa. This subfamily
represents the TDY subtype and is composed of Group D
plant MAPKs including Arabidopsis thaliana MPK18
(AtMPK18), Oryza sativa Blast- and Wound-induced MAPK1
(OsBWMK1), OsWJUMK1 (Wound- and JA-Uninducible MAPK1),
Zea mays MPK6, and the Medicago sativa TDY1 gene
product. OsBWMK1 enhances resistance to pathogenic
infections. It mediates stress-activated defense
responses by activating a transcription factor that
affects the expression of stress-related genes. AtMPK18
is involved in microtubule-related functions.

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

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.

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.

activated by the MAPK kinases MKK3 and MKK6, which in
turn are activated by upstream MAPK kinase kinases
including TAK1, ASK1, and MLK3, in response to cellular
stresses or inflammatory cytokines. Vertebrates contain
four isoforms of p38, named alpha, beta, gamma, and
delta. p38gamma, also called MAPK12, is predominantly
expressed in skeletal muscle. Unlike p38alpha and
p38beta, p38gamma is insensitive to pyridinylimidazoles.
It displays an antagonizing function compared to
p38alpha. p38gamma inhibits, while p38alpha stimulates,
c-Jun phosphorylation and AP-1 mediated transcription.
p38gamma also plays a role in the signaling between Ras
and the estrogen receptor and has been implicated to
increase cell invasion and breast cancer progression. In
Xenopus, p38gamma is critical in the meiotic maturation
of oocytes.

FGFs to FGFRs is promiscuous, in that a receptor may be
activated by several ligands and a ligand may bind to
more that one type of receptor. Alternative splicing of
FGFR1 transcripts produces a variety of isoforms, which
are differentially expressed in cells. FGFR1 binds the

been reported to bind FGF4, FGF6, and FGF9. FGFR1
signaling is critical in the control of cell migration
during embryo development. It promotes cell

in the regulation of transcription. Mutations,
insertions or deletions of FGFR1 have been identified in

with the SH3 domain containing proteins Nck, Grb2 and
PIX. Binding of group I PAKs to activated GTPases leads
to conformational changes that destabilize the AID,
allowing autophosphorylation and full activation of the

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. FGFR3 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. 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.

which is phosphorylated and activated by a MAPK kinase
(MAPKK or MKK or MAP2K), which itself is phosphorylated
and activated by a MAPK kinase kinase (MAPKKK or MKKK or

phosphorylate their downstream targets, MAPKs, at
specific threonine and tyrosine residues. There are
three MAPK subfamilies: extracellular signal-regulated
kinase (ERK), c-Jun N-terminal kinase (JNK), and p38. In
mammalian cells, there are seven MAPKKs (named MKK1-7)
and 20 MAPKKKs. Each MAPK subfamily can be activated by
at least two cognate MAPKKs and by multiple MAPKKKs.

Serine/Threonine Kinase, p21-activated kinase 1.
Serine/threonine kinases (STKs), p21-activated kinase
(PAK) 1, catalytic (c) domain. STKs catalyze the
transfer of the gamma-phosphoryl group from ATP to
serine/threonine residues on protein substrates. The PAK
subfamily is part of a larger superfamily that includes
the catalytic domains of other protein STKs, protein
tyrosine kinases, RIO kinases, aminoglycoside
phosphotransferase, choline kinase, and phosphoinositide
3-kinase. PAKs are Rho family GTPase-regulated kinases
that serve as important mediators in the function of
Cdc42 (cell division cycle 42) and Rac. PAKs from higher
eukaryotes are classified into two groups (I and II),
according to their biochemical and structural features.
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.

>gnl|CDD|176881 cd08872, START_STARD11-like, Ceramide-binding START domain of
mammalian STARD11 and related domains. This subfamily
includes the steroidogenic acute regulatory protein
(StAR)-related lipid transfer (START) domains of
mammalian STARD11 and related domains. The START domain
family belongs to the SRPBCC
(START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain
superfamily of proteins that bind hydrophobic ligands.
SRPBCC domains have a deep hydrophobic ligand-binding
pocket. STARD11 can mediate transfer of the natural
ceramide isomers, dihydroceramide and phytoceramide, as
well as ceramides having C14, C16, C18, and C20 chains.
They can also transfer diacylglycerol, but with a lower
efficiency. STARD11 is synthesized from two major
transcripts: a larger one encoding Goodpasture
antigen-binding protein (GPBP)/ceramide transporter long
form (CERTL); and a smaller one encoding
GPBPdelta26/CERT, which is deleted for 26 amino acids.
Both splicing variants mediate ceramide transfer from
the ER to the Golgi, in a non-vesicular manner. It is
likely that these two carry out different functions in
specific sub-cellular locations. These proteins have
roles in brain homeostasis and disease processes.
GPBP/CERTL exists in multiple isoforms originating from
alternative translation initiation sites and
post-translational modifications. Goodpasture syndrome
is a human disorder caused by antibodies directed
against the a3-chain of collagen type IV. GPBP/CERTL
binds and phosphorylates this antigen. The human gene
encoding STARD11 is referred to as COL4A3BP referring to
its collagen binding function. It is unknown whether the
ceramide-transfer function of GPBP/CERTL is related to
this collagen interaction. The expression of GPBP/CERTL
is elevated in these and other spontaneous autoimmune
disorders including cutaneous lupus erythematosus,
pemphigoid, and lichen planus. GPBL/CERTL contains an
N-terminal pleckstrin homology domain (PH), which
targets the protein to the Golgi, a middle region
containing two serine-rich domains (SR1, SR2), a FFAT
(two phenylalanine amino acids in an acidic tract) motif
which is involved in endoplasmic reticulum targeting,
and this C-terminal SMART domain. The shorter splicing
variant, CERT, lacks the SR2 domain.

gamma-phosphoryl group from ATP to tyrosine (tyr)

kinase (RTK) containing an extracellular region, a
transmembrane segment, and an intracellular catalytic
domain. The extracellular region contains an
immunoglobulin (Ig)-like domain, three epidermal growth
factor (EGF)-like domains, a second Ig-like domain, and
three fibronectin type III repeats. Tie receptors are
specifically expressed in endothelial cells and
hematopoietic stem cells. No specific ligand has been
identified for Tie1, although the angiopoietin, Ang-1,
binds to Tie1 through integrins at high concentrations.
In vivo studies of Tie1 show that it is critical in
vascular development.

ubiquitously and is localized in the cytoplasm. It is
also present in the ruffling edge of spreading
fibroblasts and may play a role in cell spreading. It
binds to the p21 inhibitor without any effect on its
own activity and it is overexpressed in squamous cell
carcinomas and neuroblastomas. CDK6 has also been shown
to inhibit cell differentiation in many cell types.

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.
