>gnl|CDD|200929 pfam00014, Kunitz_BPTI, Kunitz/Bovine pancreatic trypsin inhibitor
domain. Indicative of a protease inhibitor, usually a
serine protease inhibitor. Structure is a disulfide rich
alpha+beta fold. BPTI (bovine pancreatic trypsin
inhibitor) is an extensively studied model structure.
Certain family members are similar to the tick
anticoagulant peptide (TAP). This is a highly selective
inhibitor of factor Xa in the blood coagulation
pathways. TAP molecules are highly dipolar, and are
arranged to form a twisted two- stranded antiparallel
beta-sheet followed by an alpha helix.

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

>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|143201 cd05724, Ig2_Robo, Second immunoglobulin (Ig)-like domain in Robo
(roundabout) receptors. Ig2_Robo: domain similar to the
second immunoglobulin (Ig)-like domain in Robo
(roundabout) receptors. Robo receptors play a role in
the development of the central nervous system (CNS), and
are receptors of Slit protein. Slit is a repellant
secreted by the neural cells in the midline. Slit acts
through Robo to prevent most neurons from crossing the
midline from either side. Three mammalian Robo homologs
(robo1, -2, and -3), and three mammalian Slit homologs
(Slit-1,-2, -3), have been identified. Commissural
axons, which cross the midline, express low levels of
Robo; longitudinal axons, which avoid the midline,
express high levels of Robo. robo1, -2, and -3 are
expressed by commissural neurons in the vertebrate
spinal cord and Slits 1, -2, -3 are expressed at the
ventral midline. Robo-3 is a divergent member of the
Robo family which instead of being a positive regulator
of slit responsiveness, antagonizes slit responsiveness
in precrossing axons. The Slit-Robo interaction is
mediated by the second leucine-rich repeat (LRR) domain
of Slit and the two N-terminal Ig domains of Robo, Ig1
and Ig2. The primary Robo binding site for Slit2 has
been shown by surface plasmon resonance experiments and
mutational analysis to be is the Ig1 domain, while the
Ig2 domain has been proposed to harbor a weak secondary
binding site.

immunoglobulin (Ig)-like domain in neogenin and related
proteins. Neogenin is a cell surface protein which is
expressed in the developing nervous system of vertebrate
embryos in the growing nerve cells. It is also expressed
in other embryonic tissues, and may play a general role
in developmental processes such as cell migration,
cell-cell recognition, and tissue growth regulation.
Included in this group is the tumor suppressor protein

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).

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.

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.

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.

nephrin. Ig8_hNephrin_like: domain similar to the
eighth immunoglobulin-like domain in human nephrin.
Nephrin is an integral component of the slit diaphragm,
and is a central component of the glomerular
ultrafilter. Nephrin plays a structural role, and has a
role in signaling. Nephrin is a transmembrane protein
having a short intracellular portion, and an
extracellular portion comprised of eight Ig-like
domains, and one fibronectin type III-like domain. The
extracellular portions of nephrin, from neighboring foot
processes of separate podocyte cells, may interact with
each other, and in association with other components of
the slit diaphragm, form a porous molecular sieve within
the slit pore. The intracellular portion of nephrin is
associated with linker proteins, which connect nephrin
to the actin cytoskeleton. The intracellular portion is
tyrosine phosphorylated, and mediates signaling from the
slit diaphragm into the podocytes.

Ig2_VEGF-2: Second immunoglobulin (Ig)-like domain of
vascular endothelial growth factor receptor 2 (VEGFR-2).
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.

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.

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.

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

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

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,

Ig_CSPGs_LP: immunoglobulin (Ig)-like domain similar to
that found in chondroitin sulfate proteoglycans (CSPGs)
and human cartilage link protein (LP). Included in this
group are the CSPGs aggrecan, versican, and neurocan. In
CSPGs this Ig-like domain is followed by hyaluronan
(HA)-binding tandem repeats, and a C-terminal region
with epidermal growth factor-like, lectin-like, and
complement regulatory protein-like domains. Separating
these N- and C-terminal regions is a nonhomologous
glycosaminoglycan attachment region. In cartilage,
aggrecan forms cartilage link protein stabilized
aggregates with hyaluronan (HA). These aggregates
contribute to the tissue's load bearing properties.
Aggrecan and versican have a wide distribution in
connective tissue and extracellular matrices. Neurocan
is localized almost exclusively in nervous tissue.
Aggregates having other CSPGs substituting for aggrecan
may contribute to the structural integrity of many
different tissues. There is considerable evidence that
HA-binding CSPGs are involved in developmental processes
in the central nervous system. Members of the vertebrate
HPLN (hyaluronan/HA and proteoglycan binding link)
protein family are physically linked adjacent to CSPG

>gnl|CDD|213195 cd03228, ABCC_MRP_Like, ATP-binding cassette domain of multidrug
resistance protein-like transporters. The MRP
(Multidrug Resistance Protein)-like transporters are
involved in drug, peptide, and lipid export. They belong
to the subfamily C of the ATP-binding cassette (ABC)
superfamily of transport proteins. The ABCC subfamily
contains transporters with a diverse functional spectrum
that includes ion transport, cell surface receptor, and
toxin secretion activities. The MRP-like family, similar
to all ABC proteins, have a common four-domain core
structure constituted by two membrane-spanning domains,
each composed of six transmembrane (TM) helices, and two
nucleotide-binding domains (NBD). ABC transporters are a
subset of nucleotide hydrolases that contain a signature
motif, Q-loop, and H-loop/switch region, in addition to,
the Walker A motif/P-loop and Walker B motif commonly
found in a number of ATP- and GTP-binding and
hydrolyzing proteins.

>gnl|CDD|143301 cd05893, Ig_Palladin_C, C-terminal immunoglobulin (Ig)-like domain
of palladin. Ig_Palladin_C: C-terminal immunoglobulin
(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.
