>gnl|CDD|143225 cd05748, Ig_Titin_like, Immunoglobulin (Ig)-like domain of titin
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.

>gnl|CDD|143165 cd00096, Ig, Immunoglobulin domain. Ig: immunoglobulin (Ig) domain
found in the Ig superfamily. The Ig superfamily is a
heterogenous group of proteins, built on a common fold
comprised of a sandwich of two beta sheets. Members of
this group are components of immunoglobulin, neuroglia,
cell surface glycoproteins, such as, T-cell receptors,
CD2, CD4, CD8, and membrane glycoproteins, such as,
butyrophilin and chondroitin sulfate proteoglycan core
protein. A predominant feature of most Ig domains is a
disulfide bridge connecting the two beta-sheets with a
tryptophan residue packed against the disulfide bond.

(Ig)-like domain in peroxidasin. Peroxidasin has a
peroxidase domain and interacting extracellular motifs
containing four Ig-like domains. It has been suggested
that peroxidasin is secreted and has functions related
to the stabilization of the extracellular matrix. It may
play a part in various other important processes such as
removal and destruction of cells which have undergone
programmed cell death, and protection of the organism
against non-self.

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

>gnl|CDD|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|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.

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

(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

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.

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

fibroblast growth factor (FGF) receptor. Ig2_FGFR:
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.

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

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).

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.

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.

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.

Ig5_NCAM-1: The fifth immunoglobulin (Ig)-like domain of
Neural Cell Adhesion Molecule NCAM-1 (NCAM). NCAM plays
important roles in the development and regeneration of
the central nervous system, in synaptogenesis and neural
migration. NCAM mediates cell-cell and cell-substratum
recognition and adhesion via homophilic (NCAM-NCAM) and
heterophilic (NCAM-non-NCAM) interactions. NCAM is
expressed as three major isoforms having different
intracellular extensions. The extracellular portion of
NCAM has five N-terminal Ig-like domains and two
fibronectin type III domains. The double zipper adhesion
complex model for NCAM homophilic binding involves Ig1,
Ig2, and Ig3. By this model, Ig1 and Ig2 mediate
dimerization of NCAM molecules situated on the same cell
surface (cis interactions), and Ig3 domains mediate
interactions between NCAM molecules expressed on the
surface of opposing cells (trans interactions), through
binding to the Ig1 and Ig2 domains. The adhesive ability
of NCAM is modulated by the addition of polysialic acid
chains to the fifth Ig-like domain.

FGFRL1 does not have a protein tyrosine kinase domain at

suggested that FGFRL1 may not have any direct signaling
function, but instead acts as a decoy receptor trapping

>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.

(Ig)-like domain of palladin. Palladin belongs to the
palladin-myotilin-myopalladin family. Proteins belonging
to this family contain multiple Ig-like domains and
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.

activates the tyrosine kinases receptors ErbB3 and
ErbB4, initiating signaling cascades. NRG-1 has multiple
functions; for example, in the brain it regulates
various processes such as radial glia formation and
neuronal migration, dendritic development, and
expression of neurotransmitters receptors; in the
peripheral nervous system NRG-1 regulates processes such
as target cell differentiation, and Schwann cell
survival.

Ig_2: subgroup of the immunoglobulin (Ig) domain found
in the Ig superfamily. The Ig superfamily is a
heterogenous group of proteins, built on a common fold
comprised of a sandwich of two beta sheets. Members of
the Ig superfamily are components of immunoglobulin,
neuroglia, cell surface glycoproteins, such as T-cell
receptors, CD2, CD4, CD8, and membrane glycoproteins,
such as butyrophilin and chondroitin sulfate
proteoglycan core protein. A predominant feature of most
Ig domains is a disulfide bridge connecting the two

(Ig)-like domain of neural cell adhesion molecule
NCAM-1. NCAM-1 plays important roles in the development
and regeneration of the central nervous system, in
synaptogenesis and neural migration. NCAM mediates
cell-cell and cell-substratum recognition and adhesion
via homophilic (NCAM-NCAM), and heterophilic
(NCAM-nonNCAM), interactions. NCAM is expressed as three
major isoforms having different intracellular
extensions. The extracellular portion of NCAM has five
N-terminal Ig-like domains and two fibronectin type III
domains. The double zipper adhesion complex model for
NCAM homophilic binding involves the Ig1, Ig2, and Ig3
domains. By this model, Ig1 and Ig2 mediate dimerization
of NCAM molecules situated on the same cell surface (cis
interactions), and Ig3 domains mediate interactions
between NCAM molecules expressed on the surface of
opposing cells (trans interactions), through binding to
the Ig1 and Ig2 domains. The adhesive ability of NCAM is
modulated by the addition of polysialic acid chains to
the fifth Ig-like domain. Also included in this group is
NCAM-2 (also known as OCAM/mamFas II and RNCAM). NCAM-2
is differentially expressed in the developing and mature
olfactory epithelium (OE).

Gastricsins are produced in gastric mucosa of mammals.
It is synthesized by the chief cells in the stomach as
an inactive zymogen. It is self-converted to a mature
enzyme under acidic conditions. Human gastricsin is
distributed throughout all parts of the stomach.
Gastricsin is synthesized as an inactive progastricsin
that has an approximately 40 residue prosequence. It is
self-converting to a mature enzyme being triggered by a
drop in pH from neutrality to acidic conditions. Like
other aspartic proteases, gastricsin are characterized
by two catalytic aspartic residues at the active site,
and display optimal activity at acidic pH. Mature enzyme
has a pseudo-2-fold symmetry that passes through the
active site between the catalytic aspartate residues.
Structurally, aspartic proteases are bilobal enzymes,
each lobe contributing a catalytic aspartate residue,
with an extended active site cleft localized between the
two lobes of the molecule. One lobe may be evolved from
the other through ancient gene-duplication event.
Although the three-dimensional structures of the two
lobes are very similar, the amino acid sequences are
more divergent, except for the conserved catalytic site
motif. This family of aspartate proteases is classified
by MEROPS as the peptidase family A1 (pepsin A, clan
AA).

>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.
