>gnl|CDD|143237 cd05760, Ig2_PTK7, Second immunoglobulin (Ig)-like domain of
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.

>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.

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.

to the L1 subfamily of cell adhesion molecules (CAMs)
and is comprised of an extracellular region having six
Ig-like domains and five fibronectin type III domains,
a transmembrane region, and a cytoplasmic domain. NF
has many alternatively spliced isoforms having
different temporal expression patterns during
development. NF participates in axon subcellular
targeting and synapse formation, however little is
known of the functions of the different isoforms.

(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.

of peroxidasin. Ig4_Peroxidasin: the fourth
immunoglobulin (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.

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

connects these two. FGFR activation and signaling
depend on FGF-induced dimerization, a process involving
cell surface heparin or heparin sulfate proteoglycans.
This group also contains fibroblast growth factor (FGF)
receptor_like-1(FGFRL1). FGFRL1 does not have a protein
tyrosine kinase domain at its C terminus; neither does
its cytoplasmic domain appear to interact with a
signaling partner. It has been suggested that FGFRL1
may not have any direct signaling function, but instead
acts as a decoy receptor trapping FGFs and preventing
them from binding other receptors.

>gnl|CDD|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.

(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

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.

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

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. This group
also contains alpha-type platelet-derived growth factor
receptor precursor (PDGFR)-alpha (CD140a), and

(roundabout) receptors. Robo receptors play a role in
the development of the central nervous system (CNS),
and are receptors of Slit protein. Slit is a repellant
secreted by the neural cells in the midline. Slit acts
through Robo to prevent most neurons from crossing the
midline from either side. Three mammalian Robo homologs
(robo1, -2, and -3), and three mammalian Slit homologs
(Slit-1,-2, -3), have been identified. Commissural
axons, which cross the midline, express low levels of
Robo; longitudinal axons, which avoid the midline,
express high levels of Robo. robo1, -2, and -3 are
expressed by commissural neurons in the vertebrate
spinal cord and Slits 1, -2, -3 are expressed at the
ventral midline. Robo-3 is a divergent member of the
Robo family which instead of being a positive regulator
of slit responsiveness, antagonizes slit responsiveness
in precrossing axons. The Slit-Robo interaction is
mediated by the second leucine-rich repeat (LRR) domain
of Slit and the two N-terminal Ig domains of Robo, Ig1
and Ig2. The primary Robo binding site for Slit2 has
been shown by surface plasmon resonance experiments and
mutational analysis to be is the Ig1 domain, while the
Ig2 domain has been proposed to harbor a weak secondary
binding site.

Ig5_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.

>gnl|CDD|218635 pfam05556, Calsarcin, Calcineurin-binding protein (Calsarcin).
This family consists of several mammalian
calcineurin-binding proteins. The calcium- and
calmodulin-dependent protein phosphatase calcineurin
has been implicated in the transduction of signals that
control the hypertrophy of cardiac muscle and slow
fibre gene expression in skeletal muscle. Calsarcin-1
and calsarcin-2 are expressed in developing cardiac and
skeletal muscle during embryogenesis, but calsarcin-1
is expressed specifically in adult cardiac and
slow-twitch skeletal muscle, whereas calsarcin-2 is
restricted to fast skeletal muscle. Calsarcins
represent a novel family of sarcomeric proteins that
link calcineurin with the contractile apparatus,
thereby potentially coupling muscle activity to
calcineurin activation. Calsarcin-3, is expressed
specifically in skeletal muscle and is enriched in
fast-twitch muscle fibres. Like calsarcin-1 and
calsarcin-2, calsarcin-3 interacts with calcineurin,
and the Z-disc proteins alpha-actinin, gamma-filamin,
and telethonin.
