>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|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|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.

domain similar to the second immunoglobulin (Ig)-like
domain found in the receptor protein tyrosine
phosphatase (RPTP)-F, also known as LAR. LAR belongs to
the RPTP type IIa subfamily. Members of this subfamily
are cell adhesion molecule-like proteins involved in
central nervous system (CNS) development. They have
large extracellular portions, comprised of multiple
Ig-like domains and two to nine fibronectin type III
(FNIII) domains, and a cytoplasmic portion having two

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.

vascular endothelial growth factor receptor (VEGFR).
Ig2_VEGFR: Second immunoglobulin (Ig)-like domain of
vascular endothelial growth factor receptor (VEGFR).
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). VEGFRs bind VEGFs with high affinity
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.

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.

>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 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

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.

domain similar to the second immunoglobulin (Ig)-like

the CNS-related Mahya gene. Mahya genes have been
retained in certain Bilaterian branches during
evolution. They are conserved in Hymenoptera and
Deuterostomes, but are absent from other metazoan
species such as fruit fly and nematode. Mahya proteins
are secretory, with a follistatin-like domain
(Kazal-type serine/threonine protease inhibitor domain
and EF-hand calcium-binding domain), two Ig-like
domains, and a novel C-terminal domain. Mahya may be
involved in learning and memory and in processing of
sensory information in Hymenoptera and vertebrates.
Follistatin is a secreted, multidomain protein that
binds activins with high affinity and antagonizes their
signaling.

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.

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.

Contactins are comprised of six Ig domains followed by
four fibronectin type III (FnIII) domains anchored to

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

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

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

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.

Contactins are neural cell adhesion molecules and are

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

(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.

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

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

cysteine. The structure and sequence of AhpE, however,
show greater similarity to 2-cys PRXs than 1-cys PRXs.
PRXs are thiol-specific antioxidant (TSA) proteins that
confer a protective role in cells through their
peroxidase activity in which hydrogen peroxide,
peroxynitrate, and organic hydroperoxides are reduced
and detoxified using reducing equivalents derived from
either thioredoxin, glutathione, trypanothione and
AhpF. The first step of catalysis is the nucleophilic
attack by the peroxidatic cysteine on the peroxide
leading to the formation of a cysteine sulfenic acid
intermediate. The absence of a resolving cysteine
suggests that functional AhpE is regenerated by an
external reductant. The solution behavior and crystal
structure of AhpE show that it forms dimers and
octamers.

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

oligodendrocyte glycoprotein (MOG). Ig_MOG_like:
immunoglobulin (Ig)-like domain of myelin
oligodendrocyte glycoprotein (MOG). MOG, a minor
component of the myelin sheath, is an important
CNS-specific autoantigen, linked to the pathogenesis of
multiple sclerosis (MS) and experimental autoimmune
encephalomyelitis (EAE). It is a transmembrane protein
having an extracellular Ig domain. MOG is expressed in
the CNS on the outermost lamellae of the myelin sheath,
and on the surface of oligodendrocytes, and may
participate in the completion, compaction, and/or
maintenance of myelin. This group also includes
butyrophilin (BTN). BTN is the most abundant protein in
bovine milk-fat globule membrane (MFGM).

>gnl|CDD|143304 cd05896, Ig1_IL1RAPL-1_like, First immunoglobulin (Ig)-like
domain of X-linked interleukin-1 receptor accessory
protein-like 1 (IL1RAPL-1). Ig1_ IL1RAPL-1_like:
domain similar to the first immunoglobulin (Ig)-like
domain of X-linked interleukin-1 receptor accessory
protein-like 1 (IL1RAPL-1). IL-1 alpha and IL-1 beta
are cytokines which participates 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. IL1RAPL is encoded
by a gene on the X-chromosome, this gene is wholly or
partially deleted in multiple cases of non-syndromic
mental retardation. This group also contains IL1RAPL-2,
which is also encoded by a gene on the X-chromosome and
is a candidate for another non-syndromic mental
retardation loci.
