>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|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.

of human titin C terminus and similar proteins.
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.

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.

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.

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.

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.

specifically found in vertebrate striated muscle. Titin
is gigantic, depending on isoform composition it ranges

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

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

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

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.

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

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

Ig1_IL1R_like: domain similar to the first
immunoglobulin (Ig)-like domain of interleukin-1
receptor (IL1R). IL-1 alpha and IL-1 beta are cytokines
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

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.

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

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

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

Axl/Tyro3 receptor tyrosine kinases (RTKs).
Ig2_Tyro3_like: the second immunoglobulin (Ig)-like
domain in the Axl/Tyro3 family of receptor tyrosine
kinases (RTKs). This family includes Axl (also known as
Ark, Ufo, and Tyro7), Tyro3 (also known as Sky, Rse,
Brt, Dtk, and Tif), and Mer (also known as Nyk, c-Eyk,
and Tyro12). Axl/Tyro3 family receptors have an
extracellular portion with two Ig-like domains followed
by two fibronectin-types III (FNIII) domains, a
membrane-spanning single helix, and a cytoplasmic
tyrosine kinase domain. Axl, Tyro3 and Mer are widely
expressed in adult tissues, though they show higher
expression in the brain, in the lymphatic and vascular
systems, and in the testis. Axl, Tyro3, and Mer bind the
vitamin K dependent protein Gas6 with high affinity, and
in doing so activate their tyrosine kinase activity.
Axl/Gas6 signaling may play a part in cell adhesion
processes, prevention of apoptosis, and cell
proliferation.

Immunoglobulin variable domain (IgV). Members of the IgV
family are components of immunoglobulin (Ig) and T cell
receptors. The basic structure of Ig molecules is a
tetramer of two light chains and two heavy chains linked
by disulfide bonds. In Ig, each chain is composed of one
variable domain (IgV) and one or more 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 variable domain, there
are regions of even more variability called the
hypervariable or complementarity-determining regions
(CDRs) which are responsible for antigen binding. A
predominant feature of most Ig domains is the disulfide
bridge connecting 2 beta-sheets with a tryptophan
residue packed against the disulfide bond.

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.

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

are members of the Arf family that bind GDP and GTP with
very low affinity. Unlike most Arf family proteins, Arl2
is not myristoylated at its N-terminal helix. The
protein PDE-delta, first identified in photoreceptor rod
cells, binds specifically to Arl2 and is structurally
very similar to RhoGDI. Despite the high structural
similarity between Arl2 and Rho proteins and between
PDE-delta and RhoGDI, the interactions between the
GTPases and their effectors are very different. In its
GTP bound form, Arl2 interacts with the protein Binder
of Arl2 (BART), and the complex is believed to play a
role in mitochondrial adenine nucleotide transport. In
its GDP bound form, Arl2 interacts with tubulin- folding
Cofactor D; this interaction is believed to play a role
in regulation of microtubule dynamics that impact the
cytoskeleton, cell division, and cytokinesis.

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.

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.

associated with linker proteins, which connect nephrin
to the actin cytoskeleton. The intracellular portion is

similar to the first immunoglobulin (Ig)-like domain of
X-linked interleukin-1 receptor accessory protein-like 1
(IL1RAPL-1). IL-1 alpha and IL-1 beta are cytokines
which participates in the regulation of inflammation,
immune responses, and hematopoiesis. These cytokines
bind to the IL-1 receptor type 1 (IL1R1), which is
activated on additional association with an accessory
protein, IL1RAP. IL-1 also binds a second receptor
designated type II (IL1R2). Mature IL1R1 consists of
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
antagonist) is widely expressed and binds to IL-1
receptors, inhibiting the binding of IL-1 alpha and IL-1
beta. IL1RAPL is encoded by a gene on the X-chromosome,
this gene is wholly or partially deleted in multiple

also contains IL1RAPL-2, which is also encoded by a gene
on the X-chromosome and is a candidate for another

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
