>gnl|CDD|143206 cd05729, Ig2_FGFR_like, Second immunoglobulin (Ig)-like domain of
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.

>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.

cell 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.

neuregulins (NRGs). Ig_Pro_neuregulin: immunoglobulin
(Ig)-like domain in neuregulins (NRGs). NRGs are
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 similar to the C-temrinal immunoglobulin
(Ig)-like domain of myomesin and M-protein. Myomesin
and M-protein are both structural proteins localized to
the M-band, a transverse structure in the center of the

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

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.

(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.

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

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,

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.

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.

of 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).

>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.

found in Perlecan and similar proteins.
Ig3_Perlecan_like: domain similar to the third
immunoglobulin (Ig)-like domain found in Perlecan.
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.

Ig5_Titin_like: domain similar to the M5, fifth
immunoglobulin (Ig)-like domain from the human titin C
terminus. 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, and appears to function
similar to an elastic band, keeping the myosin filaments
centered in the sarcomere during muscle contraction or
stretching.

(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.

>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.

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.

is a receptor found in all major NGF targets, including
the sympathetic, trigeminal, and dorsal root ganglia,

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.

Perlecan consists of five domains. Domain I has three
putative heparan sulfate attachment sites; domain II
has four LDL receptor-like repeats, and one Ig-like
repeat; domain III resembles the short arm of laminin
chains; domain IV has multiple Ig-like repeats (21
repeats in human perlecan); and domain V resembles the
globular G domain of the laminin A chain and internal
repeats of EGF. Perlecan may participate in a variety
of biological functions including cell binding,
LDL-metabolism, basement membrane assembly and
selective permeability, calcium binding, and growth-
and neurite-promoting activities.

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.

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.

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.

(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).

Immunoglobulin (Ig)-like domain of Sema4D. Sema4D is a
Class IV semaphorin. Semaphorins are classified based
on structural features additional to the Sema domain.
Sema4D has extracellular Sema and Ig domains, a
transmembrane domain, and a short cytoplasmic domain.
Sema4D plays a part in the development of GABAergic
synapses. Sema4D in addition is an immune semaphorin.
It is abundant on resting T cells; its expression is
weak on resting B cells and antigen presenting cells
(APCs), but is upregulated by various stimuli. The
receptor used by Sema4D in the immune system is CD72.
Sem4D enhances the activation of B cells and DCs
through binding CD72, perhaps by reducing CD72s
inhibitory signals. The receptor used by Sema4D in the
non-lymphatic tissues is plexin-B1. Sem4D is anchored
to the cell surface but its extracellular domain can be
released from the cell surface by a
metalloprotease-dependent process. Sem4D may mediate
its effects in its membrane bound form, and/or its
cleaved form.

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.

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

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.

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. VEGFRs bind VEGFs with high
affinity at the Ig-like domains. VEGFR-2 (KDR/Flk-1) is
a major mediator of the mitogenic, angiogenic and
microvascular permeability-enhancing effects of VEGF-A;
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. VEGF-A also interacts with VEGFR-1,
which it binds more strongly than VEGFR-2. VEGFR-2 and
-1 may mediate a chemotactic and a survival signal in
hematopoietic stem cells or leukemia cells.

comprised of six Ig domains followed by four
fibronectin type III (FnIII) domains anchored to the

the intermolecular binding fragment, which arranges as
a compact U-shaped module by contacts between IG

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-2
is also expressed in retinal amacrine cells in the
developing chick retina, corresponding to the period of
formation and maturation of AC processes.

the catalytic domains of other kinases, such as the
typical serine/threonine/tyrosine protein kinases (PKs),
RIO kinases, actin-fragmin kinase (AFK), and
phosphoinositide 3-kinase (PI3K). It is composed of
bacterial and eukaryotic choline kinases, as well as
eukaryotic ethanolamine kinase. ChoK catalyzes the
transfer of the gamma-phosphoryl group from ATP (or CTP)
to its substrate, choline, producing phosphorylcholine
(PCho), a precursor to the biosynthesis of two major
membrane phospholipids, phosphatidylcholine (PC) and
sphingomyelin (SM). Although choline is the preferred
substrate, ChoK also shows substantial activity towards
ethanolamine and its N-methylated derivatives. ChoK
plays an important role in cell signaling pathways and
the regulation of cell growth. Along with PCho, it is
involved in malignant transformation through Ras
oncogenes in various human cancers such as breast, lung,
colon, prostate, neuroblastoma, and hepatic lymphoma. In
mammalian cells, there are three ChoK isoforms (A-1,
A-2, and B) which are active in homo or heterodimeric
forms.

IgC_MHC_II_alpha: Immunoglobulin (Ig) domain of major
histocompatibility complex (MHC) class II alpha 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.

a tetramer of two light chains and two heavy chains

constant domains (IgC); these names reflect the fact
that the variability in sequences is higher in the
variable domain than in the constant domain. Within the

variability called the hypervariable or
complementarity-determining regions (CDRs) which are
responsible for antigen binding. A predominant feature

HSPA5 (also known as 70-kDa heat shock protein 5,
glucose-regulated protein 78/GRP78, and immunoglobulin
heavy chain-binding protein/BIP, MIF2; the gene encoding
HSPA5 maps to 9q33.3.), Sacchaormyces cerevisiae Kar2p
(also known as Grp78p), and related proteins. This
subfamily belongs to the heat shock protein 70 (HSP70)
family of chaperones that assist in protein folding and
assembly and can direct incompetent "client" proteins
towards degradation. HSPA5 and Kar2p are chaperones of
the endoplasmic reticulum (ER). Typically, HSP70s have a
nucleotide-binding domain (NBD) and a substrate-binding
domain (SBD). The nucleotide sits in a deep cleft formed
between the two lobes of the NBD. The two subdomains of
each lobe change conformation between ATP-bound,
ADP-bound, and nucleotide-free states. ATP binding opens
up the substrate-binding site; substrate-binding
increases the rate of ATP hydrolysis. HSP70 chaperone
activity is regulated by various co-chaperones: J-domain
proteins and nucleotide exchange factors (NEFs).
Multiple ER DNAJ domain proteins have been identified
and may exist in distinct complexes with HSPA5 in
various locations in the ER, for example DNAJC3-p58IPK
in the lumen. HSPA5-NEFs include SIL1 and an atypical
HSP70 family protein HYOU1/ORP150. The ATPase activity
of Kar2p is stimulated by the NEFs: Sil1p and Lhs1p.

Ig receptor (pIgR). Ig_pIgR: Immunoglobulin (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.

>gnl|CDD|143186 cd04985, IgC_CH1, CH1 domain (first constant Ig domain of the heavy
chain) in immunoglobulin. IgC_CH1: The first
immunoglobulin constant domain (IgC), of immunoglobulin
(Ig) heavy chains. This domain is found on the Fab
antigen-binding fragment. The basic structure of Ig
molecules is a tetramer of two light chains and two
heavy chains linked by disulfide bonds. There are two
types of light chains: kappa and lambda; each composed
of a constant domain and a variable domain. There are
five types of heavy chains: alpha, delta, epsilon, gamma
and mu, all consisting of a variable domain (VH) and
three (in alpha, delta and gamma) or four (in epsilon
and mu) constant domains (CH1 to CH4). Ig molecules are
modular proteins, in which the variable and constant
domains have clear, conserved sequence patterns.
