>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.

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|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.

cell adhesion molecule contactin-2 and similar
proteins. Ig4_Contactin-2-like: fourth Ig domain of
the neural cell adhesion molecule contactin-2.
Contactins are 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.

Ig3_Contactin_like: Third Ig domain of contactins.

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

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.

(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.

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

Myomesin is expressed in all types of vertebrate
striated muscle; M-protein has a muscle-type specific

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|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.

(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

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

(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.

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.

from crossing the midline from either side. Three
mammalian Robo homologs (robo1, -2, and -3), and three

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).

Ig1_Contactin-5: First Ig domain of the neural cell
adhesion molecule contactin-5. Contactins are comprised
of six Ig domains followed by four fibronectin type III
(FnIII) domains, anchored to the membrane by
glycosylphosphatidylinositol. The different contactins
show different expression patterns in the central
nervous system. In rats, a lack of contactin-5 (NB-2)
results in an impairment of the neuronal activity in
the auditory system. Contactin-5 is expressed
specifically in the postnatal nervous system, peaking
at about 3 weeks postnatal. Contactin-5 is highly
expressed in the adult human brain in the occipital
lobe and in the amygdala; lower levels of expression
have been detected in the corpus callosum, caudate
nucleus, and spinal cord.

>gnl|CDD|143239 cd05762, Ig8_MLCK, Eighth immunoglobulin (Ig)-like domain of human
myosin light-chain kinase (MLCK). Ig8_MLCK: the eighth
immunoglobulin (Ig)-like domain of human myosin
light-chain kinase (MLCK). MLCK is a key regulator of
different forms of cell motility involving actin and
myosin II. Agonist stimulation of smooth muscle cells
increases cytosolic Ca2+, which binds calmodulin. This
Ca2+-calmodulin complex in turn binds to and activates
MLCK. Activated MLCK leads to the phosphorylation of the
20 kDa myosin regulatory light chain (RLC) of myosin II
and the stimulation of actin-activated myosin MgATPase
activity. MLCK is widely present in vertebrate tissues;
it phosphorylates the 20 kDa RLC of both smooth and
nonmuscle myosin II. Phosphorylation leads to the
activation of the myosin motor domain and altered
structural properties of myosin II. In smooth muscle
MLCK it is involved in initiating contraction. In
nonmuscle cells, MLCK may participate in cell division
and cell motility; it has been suggested MLCK plays a
role in cardiomyocyte differentiation and contraction
through regulation of nonmuscle myosin II.

>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.

Sema4D has extracellular Sema and Ig domains, a

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

(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).

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.

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.

receptor tyrosine kinase KIT. SCFR and the PDGFR alpha
and beta have similar organization: an extracellular
component having five Ig-like domains, a transmembrane
segment, and a cytoplasmic portion having protein
tyrosine kinase activity. SCFR and its ligand SCF are
critical for normal hematopoiesis, mast cell
development, melanocytes and gametogenesis. SCF binds to
the second and third Ig-like domains of SCFR, this
fourth Ig-like domain participates in SCFR dimerization,
which follows ligand binding. Deletion of this fourth
SCFR_Ig-like domain abolishes the ligand-induced
dimerization of SCFR and completely inhibits signal
transduction. PDGF is a potent mitogen for connective
tissue cells. PDGF-stimulated processes are mediated by
three different PDGFs (PDGF-A,-B, and C). PDGFR alpha
binds to all three PDGFs, whereas the PDGFR beta, binds
only to PDGF-B. In mice, PDGFR alpha, and PDGFR beta,
are essential for normal development.

palladin, and myopalladin function as scaffolds that
regulate actin organization. Myotilin and myopalladin
are most abundant in skeletal and cardiac muscle;
palladin is ubiquitously expressed in the organs of
developing vertebrates and plays a key role in
cellular morphogenesis. The three family members each
interact with specific molecular partners: all three
bind to alpha-actinin; in addition, palladin also binds
to vasodilator-stimulated phosphoprotein (VASP) and
ezrin, myotilin binds to filamin and actin, and
myopalladin also binds to nebulin and cardiac ankyrin

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.

complex (MHC) alpha chain immunoglobulin domain.
IgC_MHC_II_alpha: Immunoglobulin (Ig) domain of major
histocompatibility complex (MHC) class II alpha chain.
MHC class II molecules play a key role in the initiation
of the antigen-specific immune reponse. In both humans
and in mice these molecules have been shown to be
expressed constitutively on the cell surface of
professional antigen-presenting cells (APCs), for
example on B-lymphocytes, monocytes, and macrophages.
The expression of these molecules has been shown to be
induced in nonprofessional APCs such as keratinocyctes,
and they are expressed on the surface of activated human
T cells and on T cells from other species. The MHC II
molecules present antigenic peptides to CD4(+)
T-lymphocytes. These peptides derive mostly from
protelytic processing via the endocytic pathway, of
antigens internalized by the APC. These peptides bind to
the MHC class II molecules in the endosome before they
are transported to the cell surface. MHC class II
molecules are heterodimers, comprised of two
similarly-sized membrane-spanning chains, alpha and
beta. Each chain had two globular domains (N- and
C-terminal), and a membrane-anchoring transmembrane
segment. The two chains form a compact four-domain
structure. The peptide-binding site is a cleft in the
structure.

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.

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.

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.

consists of tandem winged helix-turn-helix motifs. Stn1
and Ten1 are DNA-binding proteins with specificity for
telomeric DNA substrates and both protect chromosome
termini from unregulated resection and regulate telomere
length. Stn1 complexes with Ten1 and Cdc13 to function
as a telomere-specific replication protein A (RPA)-like
complex. These three interacting proteins associate with
the telomeric overhang in budding yeast, whereas a
single protein known as Pot1 (protection of telomeres-1)
performs this function in fission yeast, and a
two-subunit complex consisting of POT1 and TPP1
associates with telomeric ssDNA in humans. S.pombe has
Stn1- and Ten1-like proteins that are essential for
chromosome end protection. Stn1 orthologues exist in all
species that have Pot1, whereas Ten1-like proteins can
be found in all fungi. Fission yeast Stn1 and Ten1
localise at telomeres in a manner that correlates with
the length of the ssDNA overhang, suggesting that they
specifically associate with the telomeric ssDNA. Two
separate protein complexes are required for chromosome
end protection in fission yeast. Protection of telomeres
by multiple proteins with OB-fold domains is conserved
in eukaryotic evolution.

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

family are physically linked adjacent to CSPG genes.
