>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.

>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|143214 cd05737, Ig_Myomesin_like_C, C-temrinal immunoglobulin (Ig)-like
domain of myomesin and M-protein. Ig_Myomesin_like_C:
domain similar to the C-temrinal immunoglobulin
(Ig)-like domain of myomesin and M-protein. Myomesin and
M-protein are both structural proteins localized to the
M-band, a transverse structure in the center of the
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.

>gnl|CDD|143205 cd05728, Ig4_Contactin-2-like, Fourth Ig domain of the neural cell
adhesion molecule contactin-2 and similar proteins.
Ig4_Contactin-2-like: fourth Ig domain of the neural
cell adhesion molecule contactin-2. Contactins are
comprised of six Ig domains followed by four fibronectin
type III (FnIII) domains anchored to the membrane by
glycosylphosphatidylinositol. Contactin-2 (aliases
TAG-1, axonin-1) facilitates cell adhesion by homophilic
binding between molecules in apposed membranes. The
first four Ig domains form the intermolecular binding
fragment which arranges as a compact U-shaped module by
contacts between Ig domains 1 and 4, and domains 2 and
3. It has been proposed that a linear zipper-like array
forms, from contactin-2 molecules alternatively provided
by the two apposed membranes.

>gnl|CDD|143225 cd05748, Ig_Titin_like, Immunoglobulin (Ig)-like domain of titin
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

(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.

>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.

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.

Perlecan may participate in a variety of biological
functions including cell binding, LDL-metabolism,
basement membrane assembly and selective permeability,
calcium binding, and growth- and neurite-promoting
activities.

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.

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.

fibroblast growth factor (FGF) receptor. Ig2_FGFR:
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.

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.

neuregulins (NRGs). Ig_Pro_neuregulin: immunoglobulin
(Ig)-like domain in neuregulins (NRGs). NRGs are
signaling molecules, which participate in cell-cell
interactions in the nervous system, breast, heart, and
other organ systems, and are implicated in the
pathology of diseases including schizophrenia, multiple
sclerosis, and breast cancer. There are four members of
the neuregulin gene family (NRG1, -2, -3, and -4). The
NRG-1 protein, binds to and activates the tyrosine
kinases receptors ErbB3 and ErbB4, initiating signaling
cascades. The other NRGs proteins bind one or the other
or both of these ErbBs. NRG-1 has multiple functions;
for example, in the brain it regulates various
processes such as radial glia formation and neuronal
migration, dendritic development, and expression of
neurotransmitters receptors; in the peripheral nervous
system NRG-1 regulates processes such as target cell
differentiation, and Schwann cell survival. There are
many NRG-1 isoforms, which arise from the alternative
splicing of mRNA. Less is known of the functions of the
other NRGs. NRG-2 and -3 are expressed predominantly in
the nervous system. NRG-2 is expressed by motor neurons
and terminal Schwann cells, and is concentrated near
synaptic sites and may be a signal that regulates
synaptic differentiation. NRG-4 has been shown to
direct pancreatic islet cell development towards the
delta-cell lineage.

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.

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.

protein that have important roles in a variety of
tissues. Functionally, semaphorins were initially
characterized for their importance in the development of
the nervous system and in axonal guidance. Later they
have been found to be important for the formation and
functioning of the cardiovascular, endocrine,
gastrointestinal, hepatic, immune, musculoskeletal,
renal, reproductive, and respiratory systems.
Semaphorins function through binding to their receptors
and transmembrane semaphorins also serves as receptors
themselves. Although molecular mechanism of semaphorins
is poorly understood, the Ig-like domains may involve in

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.

(roundabout) receptors. Ig4_Robo: domain similar to the
third immunoglobulin (Ig)-like domain in Robo
(roundabout) receptors. Robo receptors play a role in
the development of the central nervous system (CNS), and
are receptors of Slit protein. Slit is a repellant
secreted by the neural cells in the midline. Slit acts
through Robo to prevent most neurons from crossing the
midline from either side. Three mammalian Robo homologs
(robo1, -2, and -3), and three mammalian Slit homologs
(Slit-1,-2, -3), have been identified. Commissural
axons, which cross the midline, express low levels of
Robo; longitudinal axons, which avoid the midline,
express high levels of Robo. robo1, -2, and -3 are
expressed by commissural neurons in the vertebrate
spinal cord and Slits 1, -2, -3 are expressed at the
ventral midline. Robo-3 is a divergent member of the
Robo family which instead of being a positive regulator
of slit responsiveness, antagonizes slit responsiveness
in precrossing axons. The Slit-Robo interaction is
mediated by the second leucine-rich repeat (LRR) domain
of Slit and the two N-terminal Ig domains of Robo, Ig1
and Ig2. The primary Robo binding site for Slit2 has
been shown by surface plasmon resonance experiments and
mutational analysis to be is the Ig1 domain, while the
Ig2 domain has been proposed to harbor a weak secondary
binding site.

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.

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.

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.

T-cell receptor (TCR) bet a chain. IgV_TCR_beta:
immunoglobulin (Ig) variable domain of the beta 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 includes the variable domain of the alpha chain of
alpha/beta 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.

stem cell factor receptor (SCFR) and similar proteins.
Ig4_SCFR_like; fourth immunoglobulin (Ig)-like domain
of stem cell factor receptor (SCFR). In addition to
SCFR this group also includes the fourth Ig domain of
platelet-derived growth factor receptors (PDGFR), alpha
and beta, the fourth Ig domain of macrophage colony
stimulating factor (M-CSF), and the Ig domain of the
receptor tyrosine kinase KIT. SCFR and the PDGFR alpha
and beta have similar organization: an extracellular
component having five Ig-like domains, a transmembrane
segment, and a cytoplasmic portion having protein
tyrosine kinase activity. SCFR and its ligand SCF are
critical for normal hematopoiesis, mast cell
development, melanocytes and gametogenesis. SCF binds
to the second and third Ig-like domains of SCFR, this
fourth Ig-like domain participates in SCFR
dimerization, which follows ligand binding. Deletion of
this fourth SCFR_Ig-like domain abolishes the
ligand-induced dimerization of SCFR and completely
inhibits signal transduction. PDGF is a potent mitogen
for connective tissue cells. PDGF-stimulated processes
are mediated by three different PDGFs (PDGF-A,-B, and
C). PDGFR alpha binds to all three PDGFs, whereas the
PDGFR beta, binds only to PDGF-B. In mice, PDGFR alpha,
and PDGFR beta, are essential for normal development.

first immunoglobulin (Ig)-like domain of neural cell
adhesion molecule NCAM-1. NCAM-1 plays important roles
in the development and regeneration of the central
nervous system, in synaptogenesis and neural migration.
NCAM mediates cell-cell and cell-substratum recognition
and adhesion via homophilic (NCAM-NCAM), and
heterophilic (NCAM-nonNCAM), interactions. NCAM is
expressed as three major isoforms having different
intracellular extensions. The extracellular portion of
NCAM has five N-terminal Ig-like domains and two
fibronectin type III domains. The double zipper
adhesion complex model for NCAM homophilic binding
involves the Ig1, Ig2, and Ig3 domains. By this model,
Ig1 and Ig2 mediate dimerization of NCAM molecules
situated on the same cell surface (cis interactions),
and Ig3 domains mediate interactions between NCAM
molecules expressed on the surface of opposing cells
(trans interactions), through binding to the Ig1 and
Ig2 domains. The adhesive ability of NCAM is modulated
by the addition of polysialic acid chains to the fifth
Ig-like domain.

HarA is a heme-binding NEAT-domain (NEAr Transporter,
pfam05031) protein which has been shown to bind to the
haptoglobin-hemoglobin complex in order to extract heme
from it. HarA has also been reported to bind hemoglobin
directly. HarA (also known as IsdH) contains three NEAT
domains as well as a sortase A C-terminal signal for
localization to the cell wall. The heme bound at the
third of these NEAT domains has been shown to be
transferred to the IsdA protein also localized at the
cell wall, presumably through an additional specific
protein-protein interaction. Haptoglobin is a hemoglobin
carrier protein involved in scavenging hemoglobin in the
blood following red blood cell lysis and targetting it
to the liver.

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.

molecule (CEACAM) and similar proteins.
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.

adhesion molecule 3 (CADM3)), Necl-2 (CADM1), and Necl-3
(CADM2). At least five nectin-like molecules have been

N-terminal Ig-like domain of the extracellular region
belongs to the V-type subfamily of Ig domains, is
essential to cell-cell adhesion, and plays a part in the
interaction with the envelope glycoprotein D of various
viruses. Necl-1, Necl-2, and Necl-3 have
Ca(2+)-independent homophilic and heterophilic cell-cell
adhesion activity. Necl-1 is specifically expressed in
neural tissue, and is important to the formation of
synapses, axon bundles, and myelinated axons. Necl-2 is
expressed in a wide variety of tissues, and is a
putative tumour suppressor gene, which is downregulated
in aggressive neuroblastoma. Necl-3 accumulates in
central and peripheral nervous system tissue, and has
been shown to selectively interact with

IgC_MHC_II_beta: Immunoglobulin (Ig) domain of major
histocompatibility complex (MHC) class II beta 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.
