>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
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|143239 cd05762, Ig8_MLCK, Eighth immunoglobulin (Ig)-like domain of
human myosin light-chain kinase (MLCK). Ig8_MLCK: the
eighth 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.

Ig_1: subgroup of the 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
the Ig superfamily 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.

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.

C5 immunoglobulin (Ig) domain of cardiac myosin binding
protein C (MyBP-C). MyBP_C consists of repeated

between and inside domains and an additional
cardiac-specific Ig domain at the N-terminus. For
cMYBP_C an interaction has been demonstrated between
this C5 domain and the Ig C8 domain.

>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.

receptor TrkB. TrkB_d5: the fifth domain of Trk
receptor TrkB, this is an immunoglobulin (Ig)-like
domain which binds to neurotrophin. The Trk family of
receptors are tyrosine kinase receptors, which mediate
the trophic effects of the neurotrophin Nerve growth
factor (NGF) family. The Trks are activated by
dimerization, leading to autophosphorylation of
intracellular tyrosine residues, and triggering the
signal transduction pathway. TrkB shares significant
sequence homology and domain organization with TrkA,
and TrkC. The first three domains are leucine-rich
domains. The fourth and fifth domains are Ig-like
domains playing a part in ligand binding. TrKB is
recognized by brain-derived neurotrophic factor (BDNF)
and neurotrophin (NT)-4. In some cell systems NT-3 can
activate TrkA and TrkB receptors. TrKB transcripts are
found throughout multiple structures of the central and
peripheral nervous systems.

(roundabout) receptors. Ig3_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.
