>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.

>gnl|CDD|143317 cd07693, Ig1_Robo, First immunoglobulin (Ig)-like domain in Robo
(roundabout) receptors and similar proteins. Ig1_Robo:
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.

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|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.

>gnl|CDD|143177 cd04976, Ig2_VEGFR, Second immunoglobulin (Ig)-like domain of
vascular endothelial growth factor receptor (VEGFR).
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.

The reductase portion is similar in structure to NADPH
dependent cytochrome-450 reductase (CYPOR), having an

portion of FNR. NOS differs from CYPOR in a requirement
for the cofactor tetrahydrobiopterin and unlike most
CYPOR is dimeric. Nitric oxide synthase produces nitric
oxide in the conversion of L-arginine to L-citruline.
NOS has been implicated in a variety of processes
including cytotoxicity, anti-inflamation,
neurotransmission, and vascular smooth muscle
relaxation.

Ig2_FGFRL1-like: second immunoglobulin (Ig)-like domain
of fibroblast growth factor (FGF)
receptor_like-1(FGFRL1). FGFRL1 is comprised of a signal
peptide, three extracellular Ig-like modules, a
transmembrane segment, and a short intracellular domain.
FGFRL1 is expressed preferentially in skeletal tissues.
Similar to FGF receptors, the expressed protein
interacts specifically with heparin and with FGF2.
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.

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.

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.

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.

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

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

(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.

proteins. IgV_TCR_alpha: immunoglobulin (Ig) variable
domain of the alpha chain of alpha/beta T-cell antigen
receptors (TCRs). TCRs mediate antigen recognition by T
lymphocytes, and are composed of alpha and beta, or
gamma and delta, polypeptide chains with variable (V)
and constant (C) regions. This group represents the
variable domain of the alpha chain of TCRs and also
includes the variable domain of delta chains of TCRs.
Alpha/beta TCRs recognize antigen as peptide fragments
presented by major histocompatibility complex (MHC)
molecules. The variable domain of TCRs is responsible
for antigen recognition, and is located at the
N-terminus of the receptor. Gamma/delta TCRs recognize
intact protein antigens; they recognize proteins
antigens directly and without antigen processing, and
MHC independently of the bound peptide.

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.

Ig1_Contactin-2: First Ig domain of the neural cell
adhesion molecule contactin-2-like. Contactins are
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 and 4, and domains 2 and 3. 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-2
is also expressed in retinal amacrine cells in the
developing chick retina, corresponding to the period of
formation and maturation of AC processes.

subgroup of the DEDDh 3'-5' exonuclease domain family
with similarity to the epsilon subunit of DNA polymerase
III. This subfamily is composed of uncharacterized
bacterial proteins with similarity to the epsilon
subunit of DNA polymerase III (Pol III), a multisubunit
polymerase which is the main DNA replicating enzyme in
bacteria, functioning as the chromosomal replicase. The
Pol III holoenzyme is a complex of ten different
subunits, three of which (alpha, epsilon, and theta)
compose the catalytic core. The Pol III epsilon subunit,
encoded by the dnaQ gene, is a DEDDh-type 3'-5'
exonuclease which is responsible for the proofreading
activity of the polymerase, increasing the fidelity of
DNA synthesis. It contains three conserved sequence
motifs termed ExoI, ExoII and ExoIII, with a specific
Hx(4)D conserved pattern at ExoIII. These motifs are
clustered around the active site and contain four
conserved acidic residues that serve as ligands for the
two metal ions required for catalysis. The epsilon
subunit of Pol III also functions as a stabilizer of the
holoenzyme complex.

IgC_Tapasin_R: Immunoglobulin-like domain on Tapasin-R.
Tapasin is a V-C1 (variable-constant) immunoglobulin
superfamily molecule present in the endoplasmic
reticulum (ER), where it links MHC class I molecules to
the transporter associated with antigen processing
(TAP). Tapasin-R is a tapasin-related protein that
contains similar structural motifs to Tapasin, with
some marked differences, especially in the V domain,
transmembrane and cytoplasmic regions. The majority of
Tapasin-R is located within the ER; however, there may
be some expression of Tapasin-R at the cell surface.
Tapasin-R lacks an obvious ER retention signal.

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.
