>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.

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|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.

(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.

>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.

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.

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.

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

Ig_CEACAM_D1_like : immunoglobulin (IG)-like domain 1 in
carcinoembryonic antigen (CEA) related cell adhesion
molecule (CEACAM) protein subfamily-like. The CEA family
is a group of anchored or secreted glycoproteins,
expressed by epithelial cells, leukocytes, endothelial
cells and placenta. The CEA family is divided into the
CEACAM and pregnancy-specific glycoprotein (PSG)
subfamilies. This group represents the CEACAM subfamily.
CEACAM1 has many important cellular functions, it is a
cell adhesion molecule, and a signaling molecule that
regulates the growth of tumor cells, it is an angiogenic
factor, and is a receptor for bacterial and viral
pathogens, including mouse hepatitis virus (MHV). In
mice, four isoforms of CEACAM1 generated by alternative
splicing have either two [D1, D4] or four [D1-D4]
Ig-like domains on the cell surface. This family
corresponds to the D1 Ig-like domain. Also belonging to
this group is the N-terminal immunoglobulin (Ig)-like
domain of the signaling lymphocyte activation molecule
(SLAM) family, CD84-like family. The SLAM family is a
group of immune-cell specific receptors that can
regulate both adaptive and innate immune responses. SLAM
family proteins are organized as an extracellular domain
with having two or four Ig-like domains, a single
transmembrane segment, and a cytoplasmic region having
tyr-based motifs. The extracellular domain is organized
as a membrane-distal Ig variable (IgV) domain that is
responsible for ligand recognition and a
membrane-proximal truncated Ig constant-2 (IgC2) domain.

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.

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.

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.

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.

of Neural Cell Adhesion Molecule NCAM-1 (NCAM) and

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).

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.

domain similar to the C-temrinal immunoglobulin

M-protein are both structural proteins localized to the
M-band, a transverse structure in the center of the
sarcomere, and are candidates for M-band bridges. Both
proteins are modular, consisting mainly of repetitive
Ig-like and fibronectin type III (FnIII) domains.
Myomesin is expressed in all types of vertebrate
striated muscle; M-protein has a muscle-type specific
expression pattern. Myomesin is present in both slow and
fast fibers; M-protein is present only in fast fibers.
It has been suggested that myomesin acts as a molecular
spring with alternative splicing as a means of modifying
its elasticity.

vascular endothelial growth factor (VEGF) receptor (R)
and similar proteins. Ig1_VEGFR_like: first
immunoglobulin (Ig)-like domain of vascular endothelial
growth factor (VEGF) receptor(R) related proteins. 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. This group also contains
alpha-type platelet-derived growth factor receptor
precursor (PDGFR)-alpha (CD140a), and PDGFR-beta
(CD140b). PDGFRs alpha and beta have an extracellular
component with five Ig-like domains, a transmembrane
segment, and a cytoplasmic portion that has protein
tyrosine kinase activity.

Ig6_Contactin-2: Sixth 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 proce sses.

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.

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.

which participate in the regulation of inflammation,
immune responses, and hematopoiesis. These cytokines
bind to the IL-1 receptor type 1 (IL1R1), which is

three Ig-like domains, a transmembrane domain, and a
large cytoplasmic domain. Mature IL1R2 is organized
similarly except that it has a short cytoplasmic domain.
The latter does not initiate signal transduction. A
naturally occurring cytokine IL-1RA (IL-1 receptor

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.

telomeric DNA substrates and both protect chromosome
termini from unregulated resection and regulate telomere
length. Stn1 complexes with Ten1 and Cdc13 to function
as a telomere-specific replication protein A (RPA)-like
complex. These three interacting proteins associate with
the telomeric overhang in budding yeast, whereas a
single protein known as Pot1 (protection of telomeres-1)
performs this function in fission yeast, and a
two-subunit complex consisting of POT1 and TPP1
associates with telomeric ssDNA in humans. S.pombe has
Stn1- and Ten1-like proteins that are essential for
chromosome end protection. Stn1 orthologues exist in all
species that have Pot1, whereas Ten1-like proteins can
be found in all fungi. Fission yeast Stn1 and Ten1
localise at telomeres in a manner that correlates with
the length of the ssDNA overhang, suggesting that they
specifically associate with the telomeric ssDNA. Two
separate protein complexes are required for chromosome
end protection in fission yeast. Protection of telomeres
by multiple proteins with OB-fold domains is conserved

genomes of phylogenetically distinct prokaryotic
species, comprise a family with recognisable features.
This family is known as CRISPR (short for Clustered,
Regularly Interspaced Short Palindromic Repeats). A
number of protein families appear only in association
with these repeats and are designated Cas
(CRISPR-Associated) proteins. This entry describes
proteins of unknown function which are encoded in the
midst of a cas gene operon.

semaphorins. Semaphorins are classified into various
classes on the basis of structural features additional
to the Sema domain. Class III semaphorins are a
vertebrate class having a Sema domain, an Ig domain, a
short basic domain, and are secreted. They have been
shown to be axonal guidance cues and have a part in the
regulation of the cardiovascular, immune and respiratory
systems. Sema3A, the prototype member of this class III
subfamily, induces growth cone collapse and is an
inhibitor of axonal sprouting. In perinatal rat cortex
as a chemoattractant, it functions to direct, for
pyramidal neurons, the orientated extension of apical
dendrites. It may play a role, prior to the development
of apical dendrites, in signaling the radial migration
of newborn cortical neurons towards the upper layers.
Sema3A selectively inhibits vascular endothelial growth
factor receptor (VEGF)-induced angiogenesis and induces
microvascular permeability. This group also includes
Sema3B, -C, -D, -E, -G.

(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,

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.

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.

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.

adhesion molecules (CAMs) which facilitate adhesion and
signaling at various intracellular junctions. Nectins
form homophilic cis-dimers, followed by homophilic and
heterophilic trans-dimers involved in cell-cell
adhesion. Nectin-2 and nectin-3 localize at
Sertoli-spermatid junctions where they form
heterophilic trans-interactions between the cells that
are essential for the formation and maintenance of the
junctions and for spermatid development. Nectin-3 has
also been shown to form a heterophilic
trans-interaction with nectin-1 in ciliary epithelia,
establishing the apex-apex adhesion between the pigment
and non-pigment cell layers. Nectin-4 has recently
been identified in several types of breast carcinoma

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

monomeric form. Ribonucleotide reductase (RNR)
catalyzes the reductive synthesis of
deoxyribonucleotides from their corresponding
ribonucleotides. It provides the precursors necessary
for DNA synthesis. RNRs are separated into three classes
based on their metallocofactor usage. Class I RNRs,
found in eukaryotes, bacteria, and bacteriophage, use a
diiron-tyrosyl radical. Class II RNRs, found in
bacteria, bacteriophage, algae and archaea, use coenzyme
B12 (adenosylcobalamin, AdoCbl). Class III RNRs, found
in anaerobic bacteria, bacteriophage, and archaea, use
an FeS cluster and S-adenosylmethionine to generate a
glycyl radical. Many organisms have more than one class
of RNR present in their genomes. All three RNRs have a
ten-stranded alpha-beta barrel domain that is
structurally similar to the domain of PFL (pyruvate
formate lyase). Class II RNRs are found in bacteria that
can live under both aerobic and anaerobic conditions.
Many, but not all members of this class, are found to be
homodimers. This particular subfamily is found to be
active as a monomer. Adenosylcobalamin interacts
directly with an active site cysteine to form the
reactive cysteine radical.
