>gnl|CDD|143169 cd04968, Ig3_Contactin_like, Third Ig domain of contactin.
Ig3_Contactin_like: Third Ig domain of contactins.
Contactins are neural cell adhesion molecules and are
comprised of six Ig domains followed by four fibronectin
type III(FnIII) domains anchored to the membrane by
glycosylphosphatidylinositol. The first four Ig domains
form the intermolecular binding fragment, which arranges
as a compact U-shaped module via contacts between Ig
domains 1 and 4, and between Ig domains 2 and 3.
Contactin-2 (TAG-1, axonin-1) may play a part in the
neuronal processes of neurite outgrowth, axon guidance
and fasciculation, and neuronal migration. This group
also includes contactin-1 and contactin-5. The different
contactins show different expression patterns in the
central nervous system. During development and in
adulthood, contactin-2 is transiently expressed in
subsets of central and peripheral neurons. Contactin-5
is expressed specifically in the rat postnatal nervous
system, peaking at about 3 weeks postnatal, and a lack
of contactin-5 (NB-2) results in an impairment of
neuronal act ivity in the rat auditory system.
Contactin-5 is highly expressed in the adult human brain
in the occipital lobe and in the amygdala. Contactin-1
is differentially expressed in tumor tissues and may,
through a RhoA mechanism, facilitate invasion and
metastasis of human lung adenocarcinoma.

(roundabout) receptors. Ig3_Robo: domain similar to the
third immunoglobulin (Ig)-like domain in Robo
(roundabout) receptors. Robo receptors play a role in
the development of the central nervous system (CNS), and
are receptors of Slit protein. Slit is a repellant
secreted by the neural cells in the midline. Slit acts
through Robo to prevent most neurons from crossing the
midline from either side. Three mammalian Robo homologs
(robo1, -2, and -3), and three mammalian Slit homologs
(Slit-1,-2, -3), have been identified. Commissural
axons, which cross the midline, express low levels of
Robo; longitudinal axons, which avoid the midline,
express high levels of Robo. robo1, -2, and -3 are
expressed by commissural neurons in the vertebrate
spinal cord and Slits 1, -2, -3 are expressed at the
ventral midline. Robo-3 is a divergent member of the
Robo family which instead of being a positive regulator
of slit responsiveness, antagonizes slit responsiveness
in precrossing axons. The Slit-Robo interaction is
mediated by the second leucine-rich repeat (LRR) domain
of Slit and the two N-terminal Ig domains of Robo, Ig1
and Ig2. The primary Robo binding site for Slit2 has
been shown by surface plasmon resonance experiments and
mutational analysis to be is the Ig1 domain, while the
Ig2 domain has been proposed to harbor a weak secondary
binding site.

Neural Cell Adhesion Molecule NCAM-1 (NCAM).
Ig3_NCAM-1_like: domain similar to the third
immunoglobulin (Ig)-like domain of Neural Cell Adhesion
Molecule NCAM-1 (NCAM). NCAM plays important roles in
the development and regeneration of the central nervous
system, in synaptogenesis and neural migration. NCAM
mediates cell-cell and cell-substratum recognition and
adhesion via homophilic (NCAM-NCAM), and heterophilic
(NCAM-non-NCAM), interactions. NCAM is expressed as
three major isoforms having different intracellular
extensions. The extracellular portion of NCAM has five
N-terminal Ig-like domains and two fibronectin type III
domains. The double zipper adhesion complex model for
NCAM homophilic binding involves Ig1, Ig2, and Ig3. By
this model, Ig1,and Ig2 mediate dimerization of NCAM
molecules situated on the same cell surface (cis
interactions), and Ig3 domains mediate interactions
between NCAM molecules expressed on the surface of
opposing cells (trans interactions), through binding to
the Ig1 and Ig2 domains. The adhesive ability of NCAM is
modulated by the addition of polysialic acid chains to
the fifth Ig-like domain.

domain similar to the second immunoglobulin (Ig)-like
domain found in a follistatin-like molecule encoded by
the CNS-related Mahya gene. Mahya genes have been
retained in certain Bilaterian branches during
evolution. They are conserved in Hymenoptera and
Deuterostomes, but are absent from other metazoan
species such as fruit fly and nematode. Mahya proteins
are secretory, with a follistatin-like domain
(Kazal-type serine/threonine protease inhibitor domain
and EF-hand calcium-binding domain), two Ig-like
domains, and a novel C-terminal domain. Mahya may be
involved in learning and memory and in processing of
sensory information in Hymenoptera and vertebrates.
Follistatin is a secreted, multidomain protein that
binds activins with high affinity and antagonizes their
signaling.

Ig_2: subgroup of the immunoglobulin (Ig) domain found
in the Ig superfamily. The Ig superfamily is a
heterogenous group of proteins, built on a common fold
comprised of a sandwich of two beta sheets. Members of
the Ig superfamily are components of immunoglobulin,
neuroglia, cell surface glycoproteins, such as T-cell
receptors, CD2, CD4, CD8, and membrane glycoproteins,
such as butyrophilin and chondroitin sulfate
proteoglycan core protein. A predominant feature of most
Ig domains is a disulfide bridge connecting the two
beta-sheets with a tryptophan residue packed against the
disulfide bond.

>gnl|CDD|143170 cd04969, Ig5_Contactin_like, Fifth Ig domain of contactin.
Ig5_Contactin_like: Fifth Ig domain of contactins.
Contactins are neural cell adhesion molecules and are
comprised of six Ig domains followed by four fibronectin
type III(FnIII) domains anchored to the membrane by
glycosylphosphatidylinositol. The first four Ig domains
form the intermolecular binding fragment, which arranges
as a compact U-shaped module via contacts between Ig
domains 1 and 4, and between Ig domains 2 and 3.
Contactin-2 (TAG-1, axonin-1) may play a part in the
neuronal processes of neurite outgrowth, axon guidance
and fasciculation, and neuronal migration. This group
also includes contactin-1 and contactin-5. The different
contactins show different expression patterns in the
central nervous system. During development and in
adulthood, contactin-2 is transiently expressed in
subsets of central and peripheral neurons. Contactin-5
is expressed specifically in the rat postnatal nervous
system, peaking at about 3 weeks postnatal, and a lack
of contactin-5 (NB-2) results in an impairment of
neuronal act ivity in the rat auditory system.
Contactin-5 is highly expressed in the adult human brain
in the occipital lobe and in the amygdala. Contactin-1
is differentially expressed in tumor tissues and may,
through a RhoA mechanism, facilitate invasion and
metastasis of human lung adenocarcinoma.

protein tyrosine kinase (PTK) 7, also known as CCK4.
Ig2_PTK7: domain similar to the second immunoglobulin
(Ig)-like domain in protein tyrosine kinase (PTK) 7,
also known as CCK4. PTK7 is a subfamily of the receptor
protein tyrosine kinase family, and is referred to as an
RPTK-like molecule. RPTKs transduce extracellular
signals across the cell membrane, and play important
roles in regulating cell proliferation, migration, and
differentiation. PTK7 is organized as an extracellular
portion having seven Ig-like domains, a single
transmembrane region, and a cytoplasmic tyrosine
kinase-like domain. PTK7 is considered a pseudokinase as
it has several unusual residues in some of the highly
conserved tyrosine kinase (TK) motifs; it is predicted
to lack TK activity. PTK7 may function as a
cell-adhesion molecule. PTK7 mRNA is expressed at high
levels in placenta, melanocytes, liver, lung, pancreas,
and kidney. PTK7 is overexpressed in several cancers,
including melanoma and colon cancer lines.

Ig2_FGFRL1-like: second immunoglobulin (Ig)-like domain
of fibroblast growth factor (FGF)
receptor_like-1(FGFRL1). FGFRL1 is comprised of a signal
peptide, three extracellular Ig-like modules, a

FGFRL1 is expressed preferentially in skeletal tissues.
Similar to FGF receptors, the expressed protein
interacts specifically with heparin and with FGF2.
FGFRL1 does not have a protein tyrosine kinase domain at
its C terminus; neither does its cytoplasmic domain
appear to interact with a signaling partner. It has been
suggested that FGFRL1 may not have any direct signaling
function, but instead acts as a decoy receptor trapping
FGFs and preventing them from binding other receptors.

immunoglobulin (Ig)-like domain of Neural Cell Adhesion
Molecule NCAM-1 (NCAM). NCAM plays important roles in
the development and regeneration of the central nervous
system, in synaptogenesis and neural migration. NCAM
mediates cell-cell and cell-substratum recognition and
adhesion via homophilic (NCAM-NCAM), and heterophilic
(NCAM-non-NCAM), interactions. NCAM is expressed as
three major isoforms having different intracellular
extensions. The extracellular portion of NCAM has five
N-terminal Ig-like domains and two fibronectin type III
domains. The double zipper adhesion complex model for
NCAM homophilic binding involves Ig1, Ig2, and Ig3. By
this model, Ig1 and Ig2 mediate dimerization of NCAM
molecules situated on the same cell surface (cis
interactions), and Ig3 domains mediate interactions
between NCAM molecules expressed on the surface of
opposing cells (trans interactions), through binding to
the Ig1 and Ig2 domains. The adhesive ability of NCAM is
modulated by the addition of polysialic acid chains to
the fifth Ig-like domain. Also included in this group is
NCAM-2 (also known as OCAM/mamFas II and RNCAM) NCAM-2
is differentially expressed in the developing and mature
olfactory epithelium (OE).

myosin thick filaments to Z disks and extends along the
thick filament to the H zone, and appears to function
similar to an elastic band, keeping the myosin filaments
centered in the sarcomere during muscle contraction or

domain similar to the first immunoglobulin (Ig)-like
domain in Robo (roundabout) receptors. Robo receptors
play a role in the development of the central nervous
system (CNS), and are receptors of Slit protein. Slit is
a repellant secreted by the neural cells in the midline.
Slit acts through Robo to prevent most neurons from
crossing the midline from either side. Three mammalian
Robo homologs (robo1, -2, and -3), and three mammalian
Slit homologs (Slit-1,-2, -3), have been identified.
Commissural axons, which cross the midline, express low
levels of Robo; longitudinal axons, which avoid the
midline, express high levels of Robo. robo1, -2, and -3
are expressed by commissural neurons in the vertebrate
spinal cord and Slits 1, -2, -3 are expressed at the
ventral midline. Robo-3 is a divergent member of the
Robo family which instead of being a positive regulator
of slit responsiveness, antagonizes slit responsiveness
in precrossing axons. The Slit-Robo interaction is
mediated by the second leucine-rich repeat (LRR) domain
of Slit and the two N-terminal Ig domains of Robo, Ig1
and Ig2. The primary Robo binding site for Slit2 has
been shown by surface plasmon resonance experiments and
mutational analysis to be is the Ig1 domain, while the
Ig2 domain has been proposed to harbor a weak secondary
binding site.

Ig5_NCAM-1: The fifth immunoglobulin (Ig)-like domain of
Neural Cell Adhesion Molecule NCAM-1 (NCAM). NCAM plays
important roles in the development and regeneration of
the central nervous system, in synaptogenesis and neural
migration. NCAM mediates cell-cell and cell-substratum
recognition and adhesion via homophilic (NCAM-NCAM) and
heterophilic (NCAM-non-NCAM) interactions. NCAM is
expressed as three major isoforms having different
intracellular extensions. The extracellular portion of
NCAM has five N-terminal Ig-like domains and two
fibronectin type III domains. The double zipper adhesion
complex model for NCAM homophilic binding involves Ig1,
Ig2, and Ig3. By this model, Ig1 and Ig2 mediate
dimerization of NCAM molecules situated on the same cell
surface (cis interactions), and Ig3 domains mediate
interactions between NCAM molecules expressed on the
surface of opposing cells (trans interactions), through
binding to the Ig1 and Ig2 domains. The adhesive ability
of NCAM is modulated by the addition of polysialic acid
chains to the fifth Ig-like domain.

Ig1_Contactin: First Ig domain of contactins. Contactins
are neural cell adhesion molecules and are comprised of
six Ig domains followed by four fibronectin type
III(FnIII) domains anchored to the membrane by
glycosylphosphatidylinositol. The first four Ig domains
form the intermolecular binding fragment, which arranges
as a compact U-shaped module via contacts between Ig
domains 1 and 4, and between Ig domains 2 and 3.
Contactin-2 (TAG-1, axonin-1) may play a part in the
neuronal processes of neurite outgrowth, axon guidance
and fasciculation, and neuronal migration. This group
also includes contactin-1 and contactin-5. The different
contactins show different expression patterns in the
central nervous system. During development and in
adulthood, contactin-2 is transiently expressed in
subsets of central and peripheral neurons. Contactin-5
is expressed specifically in the rat postnatal nervous
system, peaking at about 3 weeks postnatal, and a lack
of contactin-5 (NB-2) results in an impairment of
neuronal activity in the rat auditory system.
Contactin-5 is highly expressed in the adult human brain
in the occipital lobe and in the amygdala. Contactin-1
is differentially expressed in tumor tissues and may,
through a RhoA mechanism, facilitate invasion and
metastasis of human lung adenocarcinoma.

Ig_Myotilin_like_C: immunoglobulin (Ig)-like domain in
myotilin, palladin, and myopalladin. Myotilin,
palladin, and myopalladin function as scaffolds that
regulate actin organization. Myotilin and myopalladin
are most abundant in skeletal and cardiac muscle;
palladin is ubiquitously expressed in the organs of
developing vertebrates and plays a key role in cellular
morphogenesis. The three family members each interact
with specific molecular partners: all three bind to
alpha-actinin; in addition, palladin also binds to
vasodilator-stimulated phosphoprotein (VASP) and ezrin,
myotilin binds to filamin and actin, and myopalladin
also binds to nebulin and cardiac ankyrin repeat protein
(CARP).

vertebrate class having a Sema domain, an Ig domain, a
short basic domain, and are secreted. They have been
shown to be axonal guidance cues and have a part in the
regulation of the cardiovascular, immune and respiratory
systems. Sema3A, the prototype member of this class III

inhibitor of axonal sprouting. In perinatal rat cortex
as a chemoattractant, it functions to direct, for
pyramidal neurons, the orientated extension of apical
dendrites. It may play a role, prior to the development
of apical dendrites, in signaling the radial migration
of newborn cortical neurons towards the upper layers.

(roundabout) receptors. Robo receptors play a role in
the development of the central nervous system (CNS), and
are receptors of Slit protein. Slit is a repellant
secreted by the neural cells in the midline. Slit acts
through Robo to prevent most neurons from crossing the
midline from either side. Three mammalian Robo homologs
(robo1, -2, and -3), and three mammalian Slit homologs
(Slit-1,-2, -3), have been identified. Commissural
axons, which cross the midline, express low levels of
Robo; longitudinal axons, which avoid the midline,
express high levels of Robo. robo1, -2, and -3 are
expressed by commissural neurons in the vertebrate
spinal cord and Slits 1, -2, -3 are expressed at the
ventral midline. Robo-3 is a divergent member of the
Robo family which instead of being a positive regulator
of slit responsiveness, antagonizes slit responsiveness
in precrossing axons. The Slit-Robo interaction is
mediated by the second leucine-rich repeat (LRR) domain
of Slit and the two N-terminal Ig domains of Robo, Ig1
and Ig2. The primary Robo binding site for Slit2 has
been shown by surface plasmon resonance experiments and
mutational analysis to be is the Ig1 domain, while the
Ig2 domain has been proposed to harbor a weak secondary
binding site.

specifically found in vertebrate striated muscle. Titin
is gigantic, depending on isoform composition it ranges

similarly to an elastic band, keeping the myosin
filaments centered in the sarcomere during muscle
contraction or stretching. Within the sarcomere, titin
is also attached to or is associated with myosin binding
protein C (MyBP-C). MyBP-C appears to contribute to the

(Ig)-like domain in neuregulins (NRGs). NRGs are
signaling molecules, which participate in cell-cell
interactions in the nervous system, breast, heart, and
other organ systems, and are implicated in the pathology
of diseases including schizophrenia, multiple sclerosis,
and breast cancer. There are four members of the
neuregulin gene family (NRG1, -2, -3, and -4). The NRG-1
protein, binds to and activates the tyrosine kinases
receptors ErbB3 and ErbB4, initiating signaling
cascades. The other NRGs proteins bind one or the other
or both of these ErbBs. NRG-1 has multiple functions;
for example, in the brain it regulates various processes
such as radial glia formation and neuronal migration,
dendritic development, and expression of
neurotransmitters receptors; in the peripheral nervous
system NRG-1 regulates processes such as target cell
differentiation, and Schwann cell survival. There are
many NRG-1 isoforms, which arise from the alternative
splicing of mRNA. Less is known of the functions of the
other NRGs. NRG-2 and -3 are expressed predominantly in
the nervous system. NRG-2 is expressed by motor neurons
and terminal Schwann cells, and is concentrated near
synaptic sites and may be a signal that regulates
synaptic differentiation. NRG-4 has been shown to direct
pancreatic islet cell development towards the delta-cell
lineage.

Ig4_SCFR_like; fourth immunoglobulin (Ig)-like domain of
stem cell factor receptor (SCFR). In addition to SCFR
this group also includes the fourth Ig domain of
platelet-derived growth factor receptors (PDGFR), alpha
and beta, the fourth Ig domain of macrophage colony
stimulating factor (M-CSF), and the Ig domain of the
receptor tyrosine kinase KIT. SCFR and the PDGFR alpha
and beta have similar organization: an extracellular
component having five Ig-like domains, a transmembrane
segment, and a cytoplasmic portion having protein
tyrosine kinase activity. SCFR and its ligand SCF are
critical for normal hematopoiesis, mast cell
development, melanocytes and gametogenesis. SCF binds to
the second and third Ig-like domains of SCFR, this
fourth Ig-like domain participates in SCFR dimerization,
which follows ligand binding. Deletion of this fourth
SCFR_Ig-like domain abolishes the ligand-induced
dimerization of SCFR and completely inhibits signal
transduction. PDGF is a potent mitogen for connective
tissue cells. PDGF-stimulated processes are mediated by
three different PDGFs (PDGF-A,-B, and C). PDGFR alpha
binds to all three PDGFs, whereas the PDGFR beta, binds
only to PDGF-B. In mice, PDGFR alpha, and PDGFR beta,
are essential for normal development.

Ig2_VEGFR: Second immunoglobulin (Ig)-like domain of
vascular endothelial growth factor receptor (VEGFR). The
VEGFRs have an extracellular component with seven
Ig-like domains, a transmembrane segment, and an
intracellular tyrosine kinase domain interrupted by a
kinase-insert domain. The VEGFR family consists of three
members, VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1) and
VEGFR-3 (Flt-4). VEGFRs bind VEGFs with high affinity at
the Ig-like domains. VEGF-A is important to the growth
and maintenance of vascular endothelial cells and to the
development of new blood- and lymphatic-vessels in
physiological and pathological states. VEGFR-2 is a
major mediator of the mitogenic, angiogenic and
microvascular permeability-enhancing effects of VEGF-A.
VEGFR-1 may play an inhibitory part in these processes
by binding VEGF and interfering with its interaction
with VEGFR-2. VEGFR-1 has a signaling role in mediating
monocyte chemotaxis. VEGFR-2 and -1 may mediate a
chemotactic and a survival signal in hematopoietic stem
cells or leukemia cells. VEGFR-3 has been shown to be
involved in tumor angiogenesis and growth.

synaptogenesis and neural migration. NCAM mediates
cell-cell and cell-substratum recognition and adhesion
via homophilic (NCAM-NCAM), and heterophilic
(NCAM-nonNCAM), interactions. NCAM is expressed as three
major isoforms having different intracellular
extensions. The extracellular portion of NCAM has five
N-terminal Ig-like domains and two fibronectin type III
domains. The double zipper adhesion complex model for
NCAM homophilic binding involves the Ig1, Ig2, and Ig3
domains. By this model, Ig1 and Ig2 mediate dimerization
of NCAM molecules situated on the same cell surface (cis
interactions), and Ig3 domains mediate interactions
between NCAM molecules expressed on the surface of
opposing cells (trans interactions), through binding to
the Ig1 and Ig2 domains. The adhesive ability of NCAM is
modulated by the addition of polysialic acid chains to
the fifth Ig-like domain. Also included in this group is

interleukin-1 receptor (IL1R) and similar proteins.
Ig2_IL1R_like: domain similar to the second
immunoglobulin (Ig)-like domain of interleukin-1
receptor (IL1R). IL-1 alpha and IL-1 beta are cytokines
which participate in the regulation of inflammation,
immune responses, and hematopoiesis. These cytokines
bind to the IL-1 receptor type 1 (IL1R1), which is
activated on additional association with an accessory
protein, IL1RAP. IL-1 also binds a second receptor
designated type II (IL1R2). Mature IL1R1 consists of
three IG-like domains, a transmembrane domain, and a
large cytoplasmic domain. Mature IL1R2 is organized
similarly except that it has a short cytoplasmic domain.
The latter does not initiate signal transduction. A
naturally occurring cytokine IL-1RA (IL-1 receptor
antagonist) is widely expressed and binds to IL-1
receptors, inhibiting the binding of IL-1 alpha and IL-1
beta. This group also contains ILIR-like 1 (IL1R1L)
which maps to the same chromosomal location as IL1R1 and
IL1R2.

immunoglobulin (Ig)-like domain of vascular endothelial
growth factor (VEGF) receptor(R) related proteins. The
VEGFRs have an extracellular component with seven
Ig-like domains, a transmembrane segment, and an
intracellular tyrosine kinase domain interrupted by a
kinase-insert domain. The VEGFR family consists of three
members, VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1) and
VEGFR-3 (Flt-4). VEGF-A interacts with both VEGFR-1 and
VEGFR-2. VEGFR-1 binds strongest to VEGF, VEGF-2 binds
more weakly. VEGFR-3 appears not to bind VEGF, but binds
other members of the VEGF family (VEGF-C and -D). VEGFRs
bind VEGFs with high affinity with the IG-like domains.
VEGF-A is important to the growth and maintenance of
vascular endothelial cells and to the development of new
blood- and lymphatic-vessels in physiological and
pathological states. VEGFR-2 is a major mediator of the
mitogenic, angiogenic and microvascular
permeability-enhancing effects of VEGF-A. VEGFR-1 may
play an inhibitory part in these processes by binding
VEGF and interfering with its interaction with VEGFR-2.
VEGFR-1 has a signaling role in mediating monocyte
chemotaxis. VEGFR-2 and -1 may mediate a chemotactic and
a survival signal in hematopoietic stem cells or
leukemia cells. VEGFR-3 has been shown to be involved in
tumor angiogenesis and growth. This group also contains
alpha-type platelet-derived growth factor receptor
precursor (PDGFR)-alpha (CD140a), and PDGFR-beta
(CD140b). PDGFRs alpha and beta have an extracellular
component with five Ig-like domains, a transmembrane
segment, and a cytoplasmic portion that has protein
tyrosine kinase activity.

gamma, delta, epsilon, and mu), which determine the type
of immunoglobulin: IgA, IgG, IgD, IgE, and IgM,
respectively. In higher vertebrates, there are two types
of light chain, designated kappa and lambda, which seem
to be functionally identical, and can associate with any
of the heavy chains.

comprised of six Ig domains followed by four fibronectin
type III (FnIII) domains anchored to the membrane by
glycosylphosphatidylinositol. Contactin-2 (TAG-1,
axonin-1) facilitates cell adhesion by homophilic
binding between molecules in apposed membranes. It may
play a part in the neuronal processes of neurite
outgrowth, axon guidance and fasciculation, and neuronal
migration. The first four Ig domains form the
intermolecular binding fragment, which arranges as a
compact U-shaped module by contacts between IG domains 1
and 4, and domains 2 and 3. The different contactins
show different expression patterns in the central
nervous system. During development and in adulthood,
contactin-2 is transiently expressed in subsets of
central and peripheral neurons. Contactin-2 is also
expressed in retinal amacrine cells in the developing
chick retina, corresponding to the period of formation
and maturation of AC processes.

mediates cell-cell and cell-substratum recognition and
adhesion via homophilic (NCAM-NCAM), and heterophilic
(NCAM-nonNCAM), interactions. NCAM is expressed as three
major isoforms having different intracellular
extensions. The extracellular portion of NCAM has five
N-terminal Ig-like domains and two fibronectin type III
domains. The double zipper adhesion complex model for
NCAM homophilic binding involves the Ig1, Ig2, and Ig3
domains. By this model, Ig1 and Ig2 mediate dimerization
of NCAM molecules situated on the same cell surface (cis
interactions), and Ig3 domains mediate interactions
between NCAM molecules expressed on the surface of
opposing cells (trans interactions), through binding to
the Ig1 and Ig2 domains. The adhesive ability of NCAM is
modulated by the addition of polysialic acid chains to
the fifth Ig-like domain.

>gnl|CDD|143269 cd05861, Ig1_PDGFR-alphabeta, Frst immunoglobulin (Ig)-like domain
of platelet-derived growth factor (PDGF) receptors (R),
alpha (CD140a), and beta (CD140b). Ig1_PDGFR-alphabeta:
The first immunoglobulin (Ig)-like domain of
platelet-derived growth factor (PDGF) receptors (R),
alpha (CD140a), and beta (CD140b). PDGF is a potent
mitogen for connective tissue cells. PDGF-stimulated
processes are mediated by three different PDGFs
(PDGF-A,-B, and C). PDGFRalpha binds to all three PDGFs,
whereas the PDGFRbeta binds only to PDGF-B. PDGFRs alpha
and beta have similar organization: an extracellular
component with five Ig-like domains, a transmembrane
segment, and a cytoplasmic portion having protein
tyrosine kinase activity. In mice, PDGFRalpha and
PDGFRbeta are essential for normal development.
