>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.

immunoglobulin (Ig)-like domain found in neuregulin
(NRG)-1. There are many NRG-1 isoforms which arise from
the alternative splicing of mRNA. NRG-1 belongs to the
neuregulin gene family, which is comprised of four
genes. This group represents NRG-1. NRGs are signaling
molecules, which participate in cell-cell interactions
in the nervous system, breast, and heart, and other
organ systems, and are implicated in the pathology of
diseases including schizophrenia, multiple sclerosis,
and breast cancer. The NRG-1 protein binds to and
activates the tyrosine kinases receptors ErbB3 and
ErbB4, initiating signaling cascades. 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.

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,

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.

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.

>gnl|CDD|143167 cd00099, IgV, Immunoglobulin variable domain (IgV). IgV:
Immunoglobulin variable domain (IgV). Members of the
IgV family are components of immunoglobulin (Ig) and T
cell receptors. The basic structure of Ig molecules is
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.

domain of T-cell receptor (TCR) alpha chain and similar
proteins. IgV_TCR_alpha: immunoglobulin (Ig) variable
domain of the alpha chain of alpha/beta T-cell antigen
receptors (TCRs). TCRs mediate antigen recognition by T
lymphocytes, and are composed of alpha and beta, or
gamma and delta, polypeptide chains with variable (V)
and constant (C) regions. This group represents the
variable domain of the alpha chain of TCRs and also
includes the variable domain of delta chains of TCRs.
Alpha/beta TCRs recognize antigen as peptide fragments
presented by major histocompatibility complex (MHC)
molecules. The variable domain of TCRs is responsible
for antigen recognition, and is located at the
N-terminus of the receptor. Gamma/delta TCRs recognize
intact protein antigens; they recognize proteins
antigens directly and without antigen processing, and
MHC independently of the bound peptide.

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.

>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.

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.

NCAM-1. NCAM-1 plays important roles in the development

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

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.

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

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

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

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

similarly except that it has a short cytoplasmic domain.
The latter does not initiate signal transduction. A

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.

beta-sheet (beta1-5) flanked on one side by alpha-2,
alpha-3 and alpha-6 helices and alpha-4 and alpha-5 on
the other. The alpha-1 helix is extended away from and
has minimal interaction with the globular part of the
protein. Four monomers interact to form a tetrameric
molecule. Four calcium atoms bind to the tetramer and
these binding sites may have functional relevance. The
function of HobA is to regulate DNA replication and its
does this by binding to DNA-A, but the exact mechanism
of how this regulation occurs is purely speculative.

>gnl|CDD|192763 pfam11465, Receptor_2B4, Natural killer cell receptor 2B4. 2B4
is a transmembrane receptor which is expressed
primarily on natural killer cells. It plays a role in
activating NK-mediated cytotoxicity through its
interaction with CD48 on target cells in a subset of
CD8 T cells. The structure of 2B4 consists of an
immunoglobulin variable domain fold and contains two
beta-sheets. One of the beta-sheets, the six-stranded
sheet, contains structural features that may have a
role in ligand recognition and receptor function.

>gnl|CDD|143273 cd05865, Ig1_NCAM-1, First immunoglobulin (Ig)-like domain of
neural cell adhesion molecule NCAM-1. Ig1_NCAM-1: first
immunoglobulin (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.

vascular endothelial growth factor receptor 2 (VEGFR-2).
Ig2_VEGF-2: Second immunoglobulin (Ig)-like domain of
vascular endothelial growth factor receptor 2 (VEGFR-2).
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. VEGFRs bind VEGFs with high
affinity at the Ig-like domains. VEGFR-2 (KDR/Flk-1) is
a major mediator of the mitogenic, angiogenic and
microvascular permeability-enhancing effects of VEGF-A;
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. VEGF-A also interacts with VEGFR-1,
which it binds more strongly than VEGFR-2. VEGFR-2 and
-1 may mediate a chemotactic and a survival signal in
hematopoietic stem cells or leukemia cells.

>gnl|CDD|143248 cd05771, IgC_Tapasin_R, Tapasin-R immunoglobulin-like domain.
IgC_Tapasin_R: Immunoglobulin-like domain on Tapasin-R.
Tapasin is a V-C1 (variable-constant) immunoglobulin
superfamily molecule present in the endoplasmic
reticulum (ER), where it links MHC class I molecules to
the transporter associated with antigen processing
(TAP). Tapasin-R is a tapasin-related protein that
contains similar structural motifs to Tapasin, with
some marked differences, especially in the V domain,
transmembrane and cytoplasmic regions. The majority of
Tapasin-R is located within the ER; however, there may
be some expression of Tapasin-R at the cell surface.
Tapasin-R lacks an obvious ER retention signal.
