>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.

(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.

of the L1 cell adhesion molecule (CAM).
Ig3_L1-CAM_like: domain similar to the third
immunoglobulin (Ig)-like domain of the L1 cell adhesion
molecule (CAM). L1 belongs to the L1 subfamily of cell
adhesion molecules (CAMs) and is comprised of an
extracellular region having six Ig-like domains and
five fibronectin type III domains, a transmembrane
region and an intracellular domain. L1 is primarily
expressed in the nervous system and is involved in its
development and function. L1 is associated with an
X-linked recessive disorder, X-linked hydrocephalus,
MASA syndrome, or spastic paraplegia type 1, that
involves abnormalities of axonal growth. This group
also contains the chicken neuron-glia cell adhesion
molecule, Ng-CAM and human neurofascin.

>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.

>gnl|CDD|143209 cd05732, Ig5_NCAM-1_like, Fifth immunoglobulin (Ig)-like domain
of Neural Cell Adhesion Molecule NCAM-1 (NCAM) and
similar proteins. Ig5_NCAM-1 like: domain similar to
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. 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).

proteoglycan perlecan, also known as HSPG2.
Ig_Perlecan_D2_like: the immunoglobulin (Ig)-like domain
II (D2) of the human basement membrane heparan sulfate
proteoglycan perlecan, also known as HSPG2. Perlecan
consists of five domains. Domain I has three putative
heparan sulfate attachment sites; domain II has four LDL
receptor-like repeats, and one Ig-like repeat; domain
III resembles the short arm of laminin chains; domain IV
has multiple Ig-like repeats (21 repeats in human
perlecan); and domain V resembles the globular G domain
of the laminin A chain and internal repeats of EGF.
Perlecan may participate in a variety of biological
functions including cell binding, LDL-metabolism,
basement membrane assembly and selective permeability,
calcium binding, and growth- and neurite-promoting
activities.

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.

(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.

Ig3_Perlecan_like: domain similar to the third

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
tandem repeat of immunoglobulin-like domains
(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
level of individual Ig-like domains, including a site
restricted to the Ig5 domain for heparin/sulfatide, a
site restricted to the Ig3 domain for nidogen-1 and
nidogen-2, a site restricted to Ig4-5 for fibronectin,
and sites restricted to Ig2 and to Ig13-15 for
fibulin-2.

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.

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.

domain (IgV) and one or more constant domains (IgC);
these names reflect the fact that the variability in
sequences is higher in the variable domain than in the
constant domain. There are five types of heavy chains
(alpha, 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.

>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.

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

vascular endothelial growth factor (VEGF) receptor(R).
IG1_VEGFR: first immunoglobulin (Ig)-like domain of
vascular endothelial growth factor (VEGF) receptor(R).
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.

Ig6_Contactin_like: Sixth 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 neur
onal 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.

(Ig)-like domain of neural cell adhesion molecule
NCAM-1. NCAM-1 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-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
NCAM-2 (also known as OCAM/mamFas II and RNCAM). NCAM-2
is differentially expressed in the developing and mature
olfactory epithelium (OE).

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.

a tetramer of two light chains and two heavy chains
linked by disulfide bonds. In Ig, each chain is
composed of one variable domain (IgV) and one or more
constant domains (IgC); these names reflect the fact
that the variability in sequences is higher in the
variable domain than in the constant domain. Within the
variable domain, there are regions of even more
variability called the hypervariable or
complementarity-determining regions (CDRs) which are
responsible for antigen binding. A predominant feature
of most Ig domains is the disulfide bridge connecting 2
beta-sheets with a tryptophan residue packed against
the disulfide bond.

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

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.

of interleukin-1 receptor-2 (IL1R2). Ig2_IL1R2_like:
domain similar to the second immunoglobulin (Ig)-like
domain of interleukin-1 receptor-2 (IL1R2). 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 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 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.

Immunoglobulin (Ig)-like domain of class III
semaphorins. Semaphorins are classified into various
classes on the basis of structural features additional

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.

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.

Ig_CSPGs_LP: immunoglobulin (Ig)-like domain similar to
that found in chondroitin sulfate proteoglycans (CSPGs)
and human cartilage link protein (LP). Included in
this group are the CSPGs aggrecan, versican, and
neurocan. In CSPGs this 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, 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.

fibronectin type III(FnIII) domains anchored to the

four Ig domains form the intermolecular binding
fragment, which arranges as a compact U-shaped module

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
