>gnl|CDD|143206 cd05729, Ig2_FGFR_like, Second immunoglobulin (Ig)-like domain of
fibroblast growth factor (FGF) receptor and similar
proteins. Ig2_FGFR_like: domain similar to the second
immunoglobulin (Ig)-like domain of fibroblast growth
factor (FGF) receptor. FGF receptors bind FGF signaling
polypeptides. FGFs participate in multiple processes
such as morphogenesis, development, and angiogenesis.
FGFs bind to four FGF receptor tyrosine kinases (FGFR1,
-2, -3, -4). Receptor diversity is controlled by
alternative splicing producing splice variants with
different ligand binding characteristics and different
expression patterns. FGFRs have an extracellular region
comprised of three Ig-like domains, a single
transmembrane helix, and an intracellular tyrosine
kinase domain. Ligand binding and specificity reside in
the Ig-like domains 2 and 3, and the linker region that
connects these two. FGFR activation and signaling depend
on FGF-induced dimerization, a process involving cell
surface heparin or heparin sulfate proteoglycans. This
group also contains fibroblast growth factor (FGF)
receptor_like-1(FGFRL1). FGFRL1 does not have a protein
tyrosine kinase domain at its C terminus; neither does
its cytoplasmic domain appear to interact with a
signaling partner. It has been suggested that FGFRL1 may
not have any direct signaling function, but instead acts
as a decoy receptor trapping FGFs and preventing them
from binding other receptors.

>gnl|CDD|143207 cd05730, Ig3_NCAM-1_like, Third immunoglobulin (Ig)-like domain of
Neural Cell Adhesion Molecule NCAM-1 (NCAM).
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.

>gnl|CDD|143317 cd07693, Ig1_Robo, First immunoglobulin (Ig)-like domain in Robo
(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.

seventh immunoglobulin (Ig)-like domain of Down Syndrome
Cell Adhesion molecule (DSCAM). DSCAM is a cell adhesion
molecule expressed largely in the developing nervous
system. The gene encoding DSCAM is located at human
chromosome 21q22, the locus associated with the mental
retardation phenotype of Down Syndrome. DSCAM is
predicted to be the largest member of the IG
superfamily. It has been demonstrated that DSCAM can
mediate cation-independent homophilic intercellular
adhesion.

poliovirus receptor (PVR, also known as CD155) and
similar proteins. Ig1_PVR_like: domain similar to the
first immunoglobulin (Ig) domain of poliovirus receptor
(PVR, also known as CD155). Poliovirus (PV) binds to its
cellular receptor (PVR/CD155) to initiate infection.
CD155 is a membrane-anchored, single-span glycoprotein;
its extracellular region has three Ig-like domains.
There are four different isotypes of CD155 (referred to
as alpha, beta, gamma, and delta), that result from
alternate splicing of the CD155 mRNA, and have identical
extracellular domains. CD155-beta and - gamma, are
secreted, CD155-alpha and delta are membrane-bound and
function as PV receptors. The virus recognition site is
contained in the amino-terminal domain, D1. Having the
virus attachment site on the receptor distal from the
plasma membrane, may be important for successful
initiation of infection of cells by the virus. CD155
binds in the poliovirus "canyon" with a footprint
similar to that of the intercellular adhesion molecule-1
receptor on human rhinoviruses. This group also includes
the first Ig-like domain of nectin-1 (also known as
poliovirus receptor related protein(PVRL)1; CD111),
nectin-3 (also known as PVRL 3), nectin-4 (also known as
PVRL4; LNIR receptor)and DNAX accessory molecule 1

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. 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.

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.

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

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

that bind to proline-rich ligands with moderate affinity
and selectivity, preferentially to PxxP motifs. They
play versatile and diverse roles in the cell including
the regulation of enzymes, changing the subcellular
localization of signaling pathway components, and
mediating the formation of multiprotein complex
assemblies.

>gnl|CDD|143295 cd05887, Ig1_Nectin-3_like, First immunoglobulin (Ig) domain of
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|143192 cd05715, Ig_P0-like, Immunoglobulin (Ig)-like domain of Protein
zero (P0) and similar proteins. Ig_P0ex-like: domain
similar to the immunoglobulin (Ig) domain of Protein
zero (P0). P0 accounts for over 50% of the total protein
in peripheral nervous system (PNS) myelin. P0 is a
single-pass transmembrane glycoprotein with a highly
basic intracellular domain and an extracellular Ig
domain. The extracellular domain of P0 (P0-ED) is
similar to the Ig variable domain, carrying one acceptor
sequence for N-linked glycosylation. P0 plays a role in
membrane adhesion in the spiral wraps of the myelin
sheath. The intracellular domain is thought to mediate
membrane apposition of the cytoplasmic faces and may,
through electrostatic interactions, interact directly
with lipid headgroups. It is thought that homophilic
interactions of the P0 extracellular domain mediate
membrane juxtaposition in the extracellular space of PNS
myelin. This group also contains the Ig domain of Sodium
channel subunit beta-2 (SCN2B), and of epithelial V-like
antigen 1 (EVA). EVA, also known as myelin protein
zero-like 2, is an adhesion molecule, which may play a
role in structural organization of the thymus and early
lymphocyte development. SCN2B subunits play a role in
determining sodium channel density and function in
neurons,and in control of electrical excitability in
the brain.
