>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.

(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.

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

protein tyrosine kinase (PTK) 7, also known as CCK4.
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
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.

(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.

(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

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.

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

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

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

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).

immunoglobulin (Ig)-like domain of fibroblast growth

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.

vascular endothelial growth factor (VEGF) receptor(R).
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.

(Ig)-like domain in the polymeric Ig receptor (pIgR).
pIgR delivers dimeric IgA and pentameric IgM to mucosal
secretions. Polymeric immunoglobulin (pIgs) are the
first defense against pathogens and toxins. IgA and IgM
can form polymers via an 18-residue extension at their
c-termini referred to as the tailpiece. pIgR transports
pIgs across mucosal epithelia into mucosal secretions.
Human pIgR is a glycosylated type I transmembrane
protein, comprised of a 620 residue extracellular
region, a 23 residue transmembrane region, and a 103
residue cytoplasmic tail. The extracellular region
contains five domains that share sequence similarity
with Ig variable (v) regions.

(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.

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.

>gnl|CDD|143191 cd05714, Ig_CSPGs_LP, Immunoglobulin (Ig)-like domain of
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.

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.

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.

>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|239948 cd04511, Nudix_Hydrolase_4, Members of the Nudix hydrolase
superfamily catalyze the hydrolysis of NUcleoside
DIphosphates linked to other moieties, X. Enzymes
belonging to this superfamily require a divalent cation,
such as Mg2+ or Mn2+, for their activity and contain a
highly conserved 23-residue nudix motif
(GX5EX7REUXEEXGU, U=I, L or V), which functions as a
metal binding and catalytic site. Substrates of nudix
hydrolases include intact and oxidatively damaged
nucleoside triphosphates, dinucleoside polyphosphates,
nucleotide-sugars and dinucleotide enzymes. These
substrates are metabolites or cell signaling molecules
that require regulation during different stages of the
cell cycle or during periods of stress. In general, the
role of the nudix hydrolase is to sanitize the
nucleotide pools and to maintain cell viability, thereby
serving as surveillance & "house-cleaning" enzymes.
Substrate specificity is used to define families within
the superfamily. Differences in substrate specificity
are determined by the N-terminal extension or by
residues in variable loop regions. Mechanistically,
substrate hydrolysis occurs by a nucleophilic
substitution reaction, with variation in the numbers and
roles of divalent cations required.
