>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.

>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.

(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.

(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.

>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.

Ig2_FGFRL1-like: second immunoglobulin (Ig)-like domain

peptide, three extracellular Ig-like modules, a

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.

the development and regeneration of the central nervous

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

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

>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.

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.

receptors TrkA, TrkB and TrkC. TrkABC_d4: the fourth
domain of Trk receptors TrkA, TrkB and TrkC, this is an
immunoglobulin (Ig)-like domain which binds to
neurotrophin. The Trk family of receptors are tyrosine
kinase receptors. They are activated by dimerization,
leading to autophosphorylation of intracellular tyrosine
residues, and triggering the signal transduction
pathway. TrkA, TrkB, and TrkC share significant sequence
homology and domain organization. The first three
domains are leucine-rich domains. The fourth and fifth
domains are Ig-like domains playing a part in ligand
binding. TrkA, Band C mediate the trophic effects of the
neurotrophin Nerve growth factor (NGF) family. TrkA is
recognized by NGF. TrKB is recognized by brain-derived
neurotrophic factor (BDNF) and neurotrophin (NT)-4. TrkC
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,
cholinergic neurons of the basal forebrain and the
striatum. TrKB transcripts are found throughout multiple
structures of the central and peripheral nervous
systems. The TrkC gene is expressed throughout the
mammalian nervous system.

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.

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

signals across the cell membrane, and play important
roles in regulating cell proliferation, migration, and
differentiation. PTK7 is organized as an extracellular
portion having seven Ig-like domains, a single
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.

Mahya gene and similar proteins. Ig2_Follistatin_like:
domain similar to the second immunoglobulin (Ig)-like
domain found in a follistatin-like molecule encoded by
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.

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.

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

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.

stem cell factor receptor (SCFR) and similar proteins.
Ig4_SCFR_like; fourth immunoglobulin (Ig)-like domain of
stem cell factor receptor (SCFR). In addition to SCFR
this group also includes the fourth Ig domain of
platelet-derived growth factor receptors (PDGFR), alpha
and beta, the fourth Ig domain of macrophage colony
stimulating factor (M-CSF), and the Ig domain of the
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.

(roundabout) receptors. Ig4_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.

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.

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

Contactins are neural cell adhesion molecules and are

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 neur
onal 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

bind VEGFs with high affinity with the IG-like domains.
VEGF-A is important to the growth and maintenance of
vascular endothelial cells and to the development of new
blood- and lymphatic-vessels in physiological and
pathological states. VEGFR-2 is a major mediator of the
mitogenic, angiogenic and microvascular
permeability-enhancing effects of VEGF-A. VEGFR-1 may
play an inhibitory part in these processes by binding
VEGF and interfering with its interaction with VEGFR-2.
VEGFR-1 has a signaling role in mediating monocyte
chemotaxis. VEGFR-2 and -1 may mediate a chemotactic and
a survival signal in hematopoietic stem cells or
leukemia cells. VEGFR-3 has been shown to be involved in
tumor angiogenesis and growth. This group also contains
alpha-type platelet-derived growth factor receptor
precursor (PDGFR)-alpha (CD140a), and PDGFR-beta
(CD140b). PDGFRs alpha and beta have an extracellular
component with five Ig-like domains, a transmembrane
segment, and a cytoplasmic portion that has protein
tyrosine kinase activity.

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.

IgC_MHC_II_beta: Immunoglobulin (Ig) domain of major
histocompatibility complex (MHC) class II beta 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.

for antigen recognition, and is located at the
N-terminus of the receptor. Gamma/delta TCRs recognize
intact protein antigens; they recognize proteins
antigens directly and without antigen processing, and

different forms of cell motility involving actin and

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

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

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.

domain of Trk receptors TrkA, TrkB and TrkC, this is an
immunoglobulin (Ig)-like domain which binds to
neurotrophin. The Trk family of receptors are tyrosine
kinase receptors. They are activated by dimerization,
leading to autophosphorylation of intracellular tyrosine
residues, and triggering the signal transduction
pathway. TrkA, TrkB, and TrkC share significant sequence
homology and domain organization. The first three
domains are leucine-rich domains. The fourth and fifth
domains are Ig-like domains playing a part in ligand
binding. TrkA, Band C mediate the trophic effects of the
neurotrophin Nerve growth factor (NGF) family. TrkA is
recognized by NGF. TrkB is recognized by brain-derived
neurotrophic factor (BDNF) and neurotrophin (NT)-4. TrkC
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,

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.

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).
