>gnl|CDD|143225 cd05748, Ig_Titin_like, Immunoglobulin (Ig)-like domain of titin
and similar proteins. Ig_Titin_like: immunoglobulin
(Ig)-like domain found in titin-like proteins. Titin
(also called connectin) is a fibrous sarcomeric protein
specifically found in vertebrate striated muscle. Titin
is gigantic, depending on isoform composition it ranges
from 2970 to 3700 kDa, and is of a length that spans
half a sarcomere. Titin largely consists of multiple
repeats of Ig-like and fibronectin type 3 (FN-III)-like
domains. Titin connects the ends of myosin thick
filaments to Z disks and extends along the thick
filament to the H zone. It appears to function
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
generation of passive tension by titin, and similar to
titin has repeated Ig-like and FN-III domains. Also
included in this group are worm twitchin and insect
projectin, thick filament proteins of invertebrate
muscle, which also have repeated Ig-like and FN-III
domains.

>gnl|CDD|143165 cd00096, Ig, Immunoglobulin domain. Ig: 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 this group 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.

C5 immunoglobulin (Ig) domain of cardiac myosin binding
protein C (MyBP-C). MyBP_C consists of repeated domains,
Ig and fibronectin type 3, and various linkers. Three
isoforms of MYBP_C exist and are included in this group:
cardiac(c), and fast and slow skeletal muscle (s)
MyBP_C. cMYBP_C has insertions between and inside
domains and an additional cardiac-specific Ig domain at
the N-terminus. For cMYBP_C an interaction has been
demonstrated between this C5 domain and the Ig C8
domain.

of fibroblast growth factor (FGF)
receptor_like-1(FGFRL1). 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 transmembrane segment, and a short
intracellular domain. 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.

>gnl|CDD|143206 cd05729, Ig2_FGFR_like, Second immunoglobulin (Ig)-like domain of
fibroblast growth factor (FGF) receptor and similar
proteins. Ig2_FGFR_like: domain similar to the second
immunoglobulin (Ig)-like domain of fibroblast growth
factor (FGF) receptor. FGF receptors bind FGF signaling
polypeptides. FGFs participate in multiple processes
such as morphogenesis, development, and angiogenesis.
FGFs bind to four FGF receptor tyrosine kinases (FGFR1,
-2, -3, -4). Receptor diversity is controlled by
alternative splicing producing splice variants with
different ligand binding characteristics and different
expression patterns. FGFRs have an extracellular region
comprised of three Ig-like domains, a single
transmembrane helix, and an intracellular tyrosine
kinase domain. Ligand binding and specificity reside in
the Ig-like domains 2 and 3, and the linker region that
connects these two. FGFR activation and signaling
depend on FGF-induced dimerization, a process involving
cell surface heparin or heparin sulfate proteoglycans.
This group also contains fibroblast growth factor (FGF)
receptor_like-1(FGFRL1). 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.

>gnl|CDD|143301 cd05893, Ig_Palladin_C, C-terminal immunoglobulin (Ig)-like
domain of palladin. Ig_Palladin_C: C-terminal
immunoglobulin (Ig)-like domain of palladin. Palladin
belongs to the palladin-myotilin-myopalladin family.
Proteins belonging to this family contain multiple
Ig-like domains and function as scaffolds, modulating
actin cytoskeleton. Palladin binds to alpha-actinin
ezrin, vasodilator-stimulated phosphoprotein VASP,
SPIN90 (DIP, mDia interacting protein), and Src.
Palladin also binds F-actin directly, via its Ig3
domain. Palladin is expressed as several alternatively
spliced isoforms, having various combinations of
Ig-like domains, in a cell-type-specific manner. It has
been suggested that palladin's different Ig-like
domains may be specialized for distinct functions.

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).

domain of myomesin and M-protein. Ig_Myomesin_like_C:
domain similar to the C-temrinal immunoglobulin
(Ig)-like domain of myomesin and M-protein. Myomesin and
M-protein are both structural proteins localized to the
M-band, a transverse structure in the center of the
sarcomere, and are candidates for M-band bridges. Both
proteins are modular, consisting mainly of repetitive
Ig-like and fibronectin type III (FnIII) domains.
Myomesin is expressed in all types of vertebrate
striated muscle; M-protein has a muscle-type specific
expression pattern. Myomesin is present in both slow and
fast fibers; M-protein is present only in fast fibers.
It has been suggested that myomesin acts as a molecular
spring with alternative splicing as a means of modifying
its elasticity.

(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.

receptors TrkA, TrkB and TrkC. TrkABC_d5: the fifth
domain of Trk receptors TrkA, TrkB and TrkC, this is an
immunoglobulin (Ig)-like domain which binds to
neurotrophin. The Trk family of receptors are tyrosine
kinase receptors. They are activated by dimerization,
leading to autophosphorylation of intracellular tyrosine
residues, and triggering the signal transduction
pathway. TrkA, TrkB, and TrkC share significant sequence
homology and domain organization. The first three
domains are leucine-rich domains. The fourth and fifth
domains are Ig-like domains playing a part in ligand
binding. TrkA, Band C mediate the trophic effects of the
neurotrophin Nerve growth factor (NGF) family. TrkA is
recognized by NGF. TrkB is recognized by brain-derived
neurotrophic factor (BDNF) and neurotrophin (NT)-4. TrkC
is recognized by NT-3. NT-3 is promiscuous as in some
cell systems it activates TrkA and TrkB receptors. TrkA
is a receptor found in all major NGF targets, including
the sympathetic, trigeminal, and dorsal root ganglia,
cholinergic neurons of the basal forebrain and the
striatum. TrKB transcripts are found throughout multiple
structures of the central and peripheral nervous
systems. The TrkC gene is expressed throughout the
mammalian nervous system.

Neural Cell Adhesion Molecule NCAM-1 (NCAM).
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.

>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, 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

myosin light-chain kinase (MLCK). Ig8_MLCK: the eighth
immunoglobulin (Ig)-like domain of human myosin
light-chain kinase (MLCK). MLCK is a key regulator of
different forms of cell motility involving actin and
myosin II. Agonist stimulation of smooth muscle cells
increases cytosolic Ca2+, which binds calmodulin. This
Ca2+-calmodulin complex in turn binds to and activates
MLCK. Activated MLCK leads to the phosphorylation of the
20 kDa myosin regulatory light chain (RLC) of myosin II
and the stimulation of actin-activated myosin MgATPase
activity. MLCK is widely present in vertebrate tissues;
it phosphorylates the 20 kDa RLC of both smooth and
nonmuscle myosin II. Phosphorylation leads to the
activation of the myosin motor domain and altered
structural properties of myosin II. In smooth muscle
MLCK it is involved in initiating contraction. In
nonmuscle cells, MLCK may participate in cell division
and cell motility; it has been suggested MLCK plays a
role in cardiomyocyte differentiation and contraction
through regulation of nonmuscle myosin II.

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

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.

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.

protein that have important roles in a variety of
tissues. Functionally, semaphorins were initially
characterized for their importance in the development
of the nervous system and in axonal guidance. Later
they have been found to be important for the formation
and functioning of the cardiovascular, endocrine,
gastrointestinal, hepatic, immune, musculoskeletal,
renal, reproductive, and respiratory systems.
Semaphorins function through binding to their receptors
and transmembrane semaphorins also serves as receptors
themselves. Although molecular mechanism of semaphorins
is poorly understood, the Ig-like domains may involve
in ligand binding or dimerization.

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.

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.

Immunoglobulin (Ig)-like domain of Sema4D. Sema4D is a
Class IV semaphorin. Semaphorins are classified based
on structural features additional to the Sema domain.
Sema4D has extracellular Sema and Ig domains, a
transmembrane domain, and a short cytoplasmic domain.
Sema4D plays a part in the development of GABAergic
synapses. Sema4D in addition is an immune semaphorin.
It is abundant on resting T cells; its expression is
weak on resting B cells and antigen presenting cells
(APCs), but is upregulated by various stimuli. The
receptor used by Sema4D in the immune system is CD72.
Sem4D enhances the activation of B cells and DCs
through binding CD72, perhaps by reducing CD72s
inhibitory signals. The receptor used by Sema4D in the
non-lymphatic tissues is plexin-B1. Sem4D is anchored
to the cell surface but its extracellular domain can be
released from the cell surface by a
metalloprotease-dependent process. Sem4D may mediate
its effects in its membrane bound form, and/or its
cleaved form.

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.

Perlecan is a large multi-domain heparin sulfate
proteoglycan, important in tissue development and
organogenesis. Perlecan can be represented as 5 major
portions; its fourth major portion (domain IV) is a

(Ig2-Ig15), which can vary in size due to alternative
splicing. Perlecan binds many cellular and
extracellular ligands. Its domain IV region has many
binding sites. Some of these have been mapped at the

component of ABC-type thermophilic oligopeptide-binding
protein Hb8-like import systems, contains the type 2
periplasmic binding fold. This family includes the
substrate-binding domain of an ABC-type
oligopeptide-binding protein Hb8 from Thermus
thermophilius and its closest homologs from other
bacteria. The structural topology of this
substrate-binding domain is similar to those of DppA
from Escherichia coli and OppA from Salmonella
typhimurium, and thus belongs to the type 2 periplasmic
binding fold protein (PBP2) superfamily. The DppA binds
dipeptides and some tripeptides and is involved in
chemotaxis toward dipeptides, whereas the OppA binds
peptides of a wide range of lengths (2-35 amino acid
residues) and plays a role in recycling of cell wall
peptides, which precludes any involvement in chemotaxis.
The type 2 periplasmic binding proteins are soluble
ligand-binding components of ABC or tripartite
ATP-independent transporters and chemotaxis systems.
Members of the PBP2 superfamily function in uptake of a
variety of metabolites in bacteria such as amino acids,
carbohydrate, ions, and polyamines. Ligands are then
transported across the cytoplasmic membrane energized by
ATP hydrolysis or electrochemical ion gradient. Besides
transport proteins, the PBP2 superfamily includes the
ligand-binding domains from ionotropic glutamate
receptors, LysR-type transcriptional regulators, and
unorthodox sensor proteins involved in signal
transduction.

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

oligosaccharyltransferase EC:2.4.1.119, transfers the
high-mannose sugar GlcNAc(2)-Man(9)-Glc(3) from a
dolichol-linked donor to an asparagine acceptor in a
consensus Asn-X-Ser/Thr motif. In most eukaryotes, the
DDOST complex is composed of three subunits, which in
humans are described as a 48kD subunit, ribophorin I,
and ribophorin II. However, the yeast DDOST appears to
consist of six subunits (alpha, beta, gamma, delta,
epsilon, zeta). The yeast beta subunit is a 45kD
polypeptide, previously discovered as the Wbp1 protein,
with known sequence similarity to the human 48kD subunit
and the other orthologues. This family includes the
48kD-like subunits from several eukaryotes; it also
includes the yeast DDOST beta subunit Wbp1.

bacterial plasmid DNA replication initiator proteins.
Pfam: PF01051 is a similar family. These RepA proteins
exist as monomers and dimers in equilibrium: monomers
bind directly to repeated DNA sequences and thus
activate replication; dimers repress repA transcription
by binding an inversely repeated DNA operator. Dimer
dissociation can occur spontaneously or be mediated by
Hsp70 chaperones.

vascular endothelial growth factor (VEGF) receptor (R)
and similar proteins. Ig1_VEGFR_like: first
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.

FGF-stimulated processes are mediated by four FGFR
tyrosine kinases (FGRF1-4). FGFRs are comprised of an
extracellular portion consisting of three Ig-like
domains, a transmembrane helix, and a cytoplasmic
portion having protein tyrosine kinase activity. The
highly conserved Ig-like domains 2 and 3, and the
linker region between D2 and D3 define a general
binding site for FGFs.

poliovirus receptor (PVR, also known as CD155) and
similar proteins. Ig1_PVR_like: domain similar to the
first immunoglobulin (Ig) domain of poliovirus receptor
(PVR, also known as CD155). Poliovirus (PV) binds to
its cellular receptor (PVR/CD155) to initiate
infection. CD155 is a membrane-anchored, single-span
glycoprotein; its extracellular region has three
Ig-like domains. There are four different isotypes of
CD155 (referred to as alpha, beta, gamma, and delta),
that result from alternate splicing of the CD155 mRNA,
and have identical extracellular domains. CD155-beta
and - gamma, are secreted, CD155-alpha and delta are
membrane-bound and function as PV receptors. The virus
recognition site is contained in the amino-terminal
domain, D1. Having the virus attachment site on the
receptor distal from the plasma membrane, may be
important for successful initiation of infection of
cells by the virus. CD155 binds in the poliovirus
"canyon" with a footprint similar to that of the
intercellular adhesion molecule-1 receptor on human
rhinoviruses. This group also includes the first
Ig-like domain of nectin-1 (also known as poliovirus
receptor related protein(PVRL)1; CD111), nectin-3 (also
known as PVRL 3), nectin-4 (also known as PVRL4; LNIR
receptor)and DNAX accessory molecule 1 (DNAM-1; CD226).

(Ig)-like domain of the nectin-like molecules Necl-1 -
Necl-3 (also known as cell adhesion molecules CADM3,
CADM1, and CADM2 respectively). Ig1_Necl-1-3_like:
N-terminal immunoglobulin (Ig)-like domain of the
nectin-like molecules Necl-1 (also known as cell
adhesion molecule 3 (CADM3)), Necl-2 (CADM1), and
Necl-3 (CADM2). At least five nectin-like molecules
have been identified (Necl-1 - Necl-5). They all have
an extracellular region containing three Ig-like
domains, a transmembrane region, and a cytoplasmic
region. The N-terminal Ig-like domain of the
extracellular region belongs to the V-type subfamily of
Ig domains, is essential to cell-cell adhesion, and
plays a part in the interaction with the envelope
glycoprotein D of various viruses. Necl-1, Necl-2, and
Necl-3 have Ca(2+)-independent homophilic and
heterophilic cell-cell adhesion activity. Necl-1 is
specifically expressed in neural tissue, and is
important to the formation of synapses, axon bundles,
and myelinated axons. Necl-2 is expressed in a wide
variety of tissues, and is a putative tumour suppressor
gene, which is downregulated in aggressive
neuroblastoma. Necl-3 accumulates in central and
peripheral nervous system tissue, and has been shown to
selectively interact with oligodendrocytes. This group
also contains Class-I MHC-restricted T-cell-associated
molecule (CRTAM), whose expression pattern is
consistent with its expression in Class-I
MHC-restricted T-cells.
