>gnl|CDD|143201 cd05724, Ig2_Robo, Second immunoglobulin (Ig)-like domain in Robo
(roundabout) receptors. Ig2_Robo: domain similar to the
second 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.

>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.

Ig4_Contactin-2-like: fourth Ig domain of the neural

comprised of six Ig domains followed by four fibronectin
type III (FnIII) domains anchored to the membrane by
glycosylphosphatidylinositol. Contactin-2 (aliases
TAG-1, axonin-1) facilitates cell adhesion by homophilic
binding between molecules in apposed membranes. 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. It has been proposed that a linear zipper-like array
forms, from contactin-2 molecules alternatively provided
by the two apposed membranes.

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.

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.

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.

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.

hyaluronan (HA)-binding tandem repeats, and a
C-terminal region with epidermal growth factor-like,
lectin-like, and complement regulatory protein-like
domains. Separating these N- and C-terminal regions is
a nonhomologous glycosaminoglycan attachment region. In
cartilage, aggrecan forms cartilage link protein
stabilized aggregates with hyaluronan (HA). These
aggregates contribute to the tissue's load bearing
properties. Aggrecan and versican have a wide
distribution in connective tissue and extracellular
matrices. Neurocan is localized almost exclusively in
nervous tissue. Aggregates having other CSPGs
substituting for aggrecan may contribute to the
structural integrity of many different tissues. There
is considerable evidence that HA-binding CSPGs are
involved in developmental processes in the central
nervous system. Members of the vertebrate HPLN
(hyaluronan/HA and proteoglycan binding link) protein
family are physically linked adjacent to CSPG genes.

(roundabout) receptors. Ig4_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.

Ig1_Contactin-2: First Ig domain of the neural cell
adhesion molecule contactin-2-like. Contactins are
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.

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.

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

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.

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.

binds the type II (IL1R2) represented in this group.
Mature IL1R2 consists of three IG-like domains, a
transmembrane domain, and a short cytoplasmic domain. It
lacks the large cytoplasmic domain of Mature IL1R1, and
does not initiate signal transduction. A naturally

widely expressed and binds to IL-1 receptors, inhibiting
the binding of IL-1 alpha and IL-1 beta.

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.

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.

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

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.

chondroitin sulfate proteoglycan core protein (CSPG),
versican. Ig_Versican: immunoglobulin (Ig)-like domain
of the chondroitin sulfate proteoglycan core protein
(CSPG), versican. In CSPGs, the Ig-like domain is
followed by hyaluronan (HA)-binding tandem repeats, and
a C-terminal region with epidermal growth factor-like,
lectin-like, and complement regulatory protein-like
domains. Separating these N- and C-terminal regions is a
nonhomologous glycosaminoglycan attachment region. In
cartilage, the CSPG aggrecan (not included in this
group) forms cartilage link protein stabilized
aggregates with HA. These aggregates contribute to the
tissue's load bearing properties. Like aggrecan,
versican has a wide distribution in connective tissue
and extracellular matrices. Aggregates having other
CSPGs substituting for aggrecan may contribute to the
structural integrity of many different tissues. Members
of the vertebrate HPLN (hyaluronan/HA and proteoglycan
binding link) protein family are physically linked
adjacent to CSPG genes.

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).

Ig5_Titin_like: domain similar to the M5, fifth
immunoglobulin (Ig)-like domain from the human titin C
terminus. 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, and appears to function
similar to an elastic band, keeping the myosin filaments
centered in the sarcomere during muscle contraction or
stretching.

>gnl|CDD|143219 cd05742, Ig1_VEGFR_like, First immunoglobulin (Ig)-like domain of
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.

class III semaphorin. Ig_Semaphorin_class III;
Immunoglobulin (Ig)-like domain of class III
semaphorins. Semaphorins are classified into various
classes on the basis of structural features additional
to the Sema domain. Class III semaphorins are a
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
subfamily, induces growth cone collapse and is an
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.
Sema3A selectively inhibits vascular endothelial growth
factor receptor (VEGF)-induced angiogenesis and induces
microvascular permeability. This group also includes
Sema3B, -C, -D, -E, -G.

cardiac(c), and fast and slow skeletal muscle (s)
MyBP_C. cMYBP_C has insertions between and inside
