>gnl|CDD|143202 cd05725, Ig3_Robo, Third immunoglobulin (Ig)-like domain in Robo
(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.

>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|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.

fibroblast growth factor (FGF) receptor and similar

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.

regulate actin organization. Myotilin and myopalladin
are most abundant in skeletal and cardiac muscle;
palladin is ubiquitously expressed in the organs of
developing vertebrates and plays a key role in cellular
morphogenesis. The three family members each interact
with specific molecular partners: all three bind to
alpha-actinin; in addition, palladin also binds to
vasodilator-stimulated phosphoprotein (VASP) and ezrin,
myotilin binds to filamin and actin, and myopalladin
also binds to nebulin and cardiac ankyrin repeat protein
(CARP).

reside in the Ig-like domains 2 and 3, and the linker

involving cell surface heparin or heparin sulfate
proteoglycans.

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.

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.

adhesion molecule contactin-2 and similar proteins.
Ig4_Contactin-2-like: fourth Ig domain of the neural
cell adhesion molecule contactin-2. Contactins are
comprised of six Ig domains followed by four fibronectin
type III (FnIII) domains anchored to the membrane by
glycosylphosphatidylinositol. 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.

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.

Neural Cell Adhesion Molecule NCAM-1 (NCAM) and similar
proteins. Ig5_NCAM-1 like: domain similar to 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).

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

>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.

It has been suggested that myomesin acts as a molecular
spring with alternative splicing as a means of modifying
its elasticity.

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.

Neural Cell Adhesion Molecule NCAM-1 (NCAM).
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.

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

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

>gnl|CDD|143171 cd04970, Ig6_Contactin_like, Sixth Ig domain of contactin.
Ig6_Contactin_like: Sixth 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 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
metastasis of human lung adenocarcinoma.

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

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.

receptors TrkA, TrkB and TrkC. TrkABC_d5: the fifth
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.
