>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.

>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|143202 cd05725, Ig3_Robo, Third immunoglobulin (Ig)-like domain in Robo
(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.

>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.

immunoglobulin (Ig)-like domain in neogenin and related
proteins. Neogenin is a cell surface protein which is
expressed in the developing nervous system of
vertebrate embryos in the growing nerve cells. It is
also expressed in other embryonic tissues, and may play
a general role in developmental processes such as cell
migration, cell-cell recognition, and tissue growth
regulation. Included in this group is the tumor
suppressor protein DCC, which is deleted in colorectal
carcinoma . DCC and neogenin each have four Ig-like
domains followed by six fibronectin type III domains, a
transmembrane domain, and an intracellular domain.

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.

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.

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).

>gnl|CDD|143168 cd04967, Ig1_Contactin, First Ig domain of contactin.
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.

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.

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.

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

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.

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

(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).

play a role in the development of the central nervous

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

vascular endothelial growth factor receptor 1
(VEGFR-1). Ig2_VEGFR-1: Second immunoglobulin
(Ig)-like domain of vascular endothelial growth factor
receptor 1 (VEGFR-1). 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. VEGFRs bind
VEGFs with high affinity at the Ig-like domains.
VEGFR-1 binds VEGF-A strongly; 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-1 may play an inhibitory rolet in the
function of VEGFR-2 by binding VEGF-A and interfering
with its interaction with VEGFR-2. VEGFR-1 has a
signaling role in mediating monocyte chemotaxis and may
mediate a chemotactic and a survival signal in
hematopoietic stem cells or leukemia cells.
