>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|143201 cd05724, Ig2_Robo, Second immunoglobulin (Ig)-like domain in Robo
(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.

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
membranes.

>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.

(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.

Ig3_NCAM-1_like: domain similar to the third
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.

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

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.

(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

projectin, thick filament proteins of invertebrate
muscle, which also have repeated Ig-like and FN-III

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.

neurotrophin. The Trk family of receptors are tyrosine
kinase receptors. They are activated by dimerization,
leading to autophosphorylation of intracellular tyrosine

is recognized by NT-3. NT-3 is promiscuous as in some
cell systems it activates TrkA and TrkB receptors. TrkA
is a receptor found in all major NGF targets, including
the sympathetic, trigeminal, and dorsal root ganglia,

are neural cell adhesion molecules and are comprised of

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

Ig1_Contactin-2: First Ig domain of the neural cell
adhesion molecule contactin-2-like. Contactins are
comprised of six Ig domains followed by four fibronectin
type III (FnIII) domains anchored to the membrane by
glycosylphosphatidylinositol. Contactin-2 (TAG-1,
axonin-1) facilitates cell adhesion by homophilic
binding between molecules in apposed membranes. It may
play a part in the neuronal processes of neurite
outgrowth, axon guidance and fasciculation, and neuronal
migration. 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. 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-2 is also
expressed in retinal amacrine cells in the developing
chick retina, corresponding to the period of formation
and maturation of AC processes.

Nephrin is an integral component of the slit diaphragm,
and is a central component of the glomerular
ultrafilter. Nephrin plays a structural role, and has a
role in signaling. Nephrin is a transmembrane protein
having a short intracellular portion, and an
extracellular portion comprised of eight Ig-like
domains, and one fibronectin type III-like domain. The
extracellular portions of nephrin, from neighboring foot
processes of separate podocyte cells, may interact with
each other, and in association with other components of
the slit diaphragm, form a porous molecular sieve within
the slit pore. The intracellular portion of nephrin is
associated with linker proteins, which connect nephrin
to the actin cytoskeleton. The intracellular portion is
tyrosine phosphorylated, and mediates signaling from the
slit diaphragm into the podocytes.

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,

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

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

Sema4D has extracellular Sema and Ig domains, a

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,

(roundabout) receptors and similar proteins. Ig1_Robo:
domain similar to the first 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.

(Ig)-like domain of palladin. Palladin belongs to the
palladin-myotilin-myopalladin family. Proteins belonging

function as scaffolds, modulating actin cytoskeleton.
Palladin binds to alpha-actinin ezrin,
vasodilator-stimulated phosphoprotein VASP, SPIN90 (DIP,
mDia interacting protein), and Src. Palladin also binds
F-actin directly, via its Ig3 domain. Palladin is
expressed as several alternatively spliced isoforms,
having various combinations of Ig-like domains, in a
cell-type-specific manner. It has been suggested that
palladin's different Ig-like domains may be specialized
for distinct functions.

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.

Ig_CEACAM_D1_like : immunoglobulin (IG)-like domain 1 in
carcinoembryonic antigen (CEA) related cell adhesion
molecule (CEACAM) protein subfamily-like. The CEA family
is a group of anchored or secreted glycoproteins,
expressed by epithelial cells, leukocytes, endothelial
cells and placenta. The CEA family is divided into the
CEACAM and pregnancy-specific glycoprotein (PSG)
subfamilies. This group represents the CEACAM subfamily.
CEACAM1 has many important cellular functions, it is a
cell adhesion molecule, and a signaling molecule that
regulates the growth of tumor cells, it is an angiogenic
factor, and is a receptor for bacterial and viral
pathogens, including mouse hepatitis virus (MHV). In
mice, four isoforms of CEACAM1 generated by alternative
splicing have either two [D1, D4] or four [D1-D4]
Ig-like domains on the cell surface. This family
corresponds to the D1 Ig-like domain. Also belonging to
this group is the N-terminal immunoglobulin (Ig)-like
domain of the signaling lymphocyte activation molecule
(SLAM) family, CD84-like family. The SLAM family is a
group of immune-cell specific receptors that can
regulate both adaptive and innate immune responses. SLAM
family proteins are organized as an extracellular domain
with having two or four Ig-like domains, a single
transmembrane segment, and a cytoplasmic region having
tyr-based motifs. The extracellular domain is organized
as a membrane-distal Ig variable (IgV) domain that is
responsible for ligand recognition and a
membrane-proximal truncated Ig constant-2 (IgC2) domain.

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.

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.

Ig1_FcgammaR_like: domain similar to the first
immunoglobulin (Ig)-like domain of Fcgamma-receptors
(FcgammaRs). Interactions between IgG and FcgammaR are
important to the initiation of cellular and humoral
response. IgG binding to FcgammaR leads to a cascade of
signals and ultimately to functions such as
antibody-dependent-cellular-cytotoxicity (ADCC),
endocytosis, phagocytosis, release of inflammatory
mediators, etc. FcgammaR has two Ig-like domains. This
group also contains FcepsilonRI, which binds IgE with
high affinity.

chondroitin sulfate proteoglycans (CSPGs), human
cartilage link protein (LP) and similar proteins.
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.

IG-like domains and two to nine fibronectin type III
(FNIII) domains, and a cytoplasmic portion having two

nectin-3 (also known as poliovirus receptor related
protein 3) and similar proteins. Ig1_Nectin-3_like:
domain similar to the first immunoglobulin (Ig) domain
of nectin-3 (also known as poliovirus receptor related
protein 3). Nectin-3 belongs to the nectin family
comprised of four transmembrane glycoproteins (nectins-1
through -4). Nectins are synaptic cell adhesion
molecules (CAMs) which participate in adhesion and
signaling at various intracellular junctions. Nectins
form homophilic cis-dimers, followed by homophilic and
heterophilic trans-dimers involved in cell-cell
adhesion. For example, during spermatid development, the
nectin-3,-2 trans-interaction is required for the
formation of Sertoli cell-spermatid junctions in testis,
and during morphogenesis of the ciliary body, the
nectin-3,-1 trans-interaction is important for apex-apex
adhesion between the pigment and non-pigment layers of
the ciliary epithelia. Nectins also heterophilically
trans-interact with other CAMs such as nectin-like
molecules (Necls); nectin-3 for example, trans-interacts
with Necl-5, regulating cell movement and proliferation.
Other proteins with which nectin-3 interacts include the
actin filament-binding protein, afadin, integrin
alpha-beta3, Par-3, and PDGF receptor; its interaction
with PDGF receptor regulates the latter's signaling for
anti-apoptosis.

>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.

>gnl|CDD|143305 cd05897, Ig2_IL1R2_like, Second immunoglobulin (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.
