>gnl|CDD|107357 cd06362, PBP1_mGluR, Ligand binding domain of the metabotropic
glutamate receptors (mGluR). Ligand binding domain of
the metabotropic glutamate receptors (mGluR), which are
members of the family C of G-protein-coupled receptors
that transduce extracellular signals into G-protein
activation and ultimately into cellular responses.
mGluRs bind to glutamate and function as an excitatory
neurotransmitter; they are involved in learning, memory,
anxiety, and the perception of pain. Eight subtypes of
mGluRs have been cloned so far, and are classified into
three groups according to their sequence similarities,
transduction mechanisms, and pharmacological profiles.
Group I is composed of mGlu1R and mGlu5R that both
stimulate PLC hydrolysis. Group II includes mGlu2R and
mGlu3R, which inhibit adenylyl cyclase, as do mGlu4R,
mGlu6R, mGlu7R, and mGlu8R, which form group III.

This is a domain of seven transmembrane regions that
forms the C-terminus of some subclass 3
G-coupled-protein receptors. It is often associated with
a downstream cysteine-rich linker domain, NCD3G
pfam07562, which is the human sweet-taste receptor, and
the N-terminal domain, ANF_receptor pfam01094. The seven
TM regions assemble in such a way as to produce a
docking pocket into which such molecules as cyclamate
and lactisole have been found to bind and consequently
confer the taste of sweetness.

>gnl|CDD|153138 cd06350, PBP1_GPCR_family_C_like, Ligand-binding domain of
membrane-bound glutamate receptors that mediate
excitatory transmission on the cellular surface through
initial binding of glutamate and are categorized into
ionotropic glutamate receptors (iGluRs) and metabotropic
glutamate receptors (mGluRs). Ligand-binding domain of
membrane-bound glutamate receptors that mediate
excitatory transmission on the cellular surface through
initial binding of glutamate and are categorized into
ionotropic glutamate receptors (iGluRs) and metabotropic
glutamate receptors (mGluRs). The metabotropic glutamate
receptors (mGluR) are key receptors in the modulation of
excitatory synaptic transmission in the central nervous
system. The mGluRs are coupled to G proteins and are
thus distinct from the iGluRs which internally contain
ligand-gated ion channels. The mGluR structure is
divided into three regions: the extracellular region,
the seven-spanning transmembrane region and the
cytoplasmic region. The extracellular region is further
devided into the ligand-binding domain (LBD) and the
cysteine-rich domain. The LBD has sequence similarity to
the LIVBP, which is a bacterial periplasmic protein
(PBP), as well as to the extracellular region of both
iGluR and the gamma-aminobutyric acid (GABA)b receptor.
iGluRs are divided into three main subtypes based on
pharmacological profile: NMDA, AMPA, and kainate
receptors. All family C GPCRs have a large extracellular
N terminus that contain a domain with homology to
bacterial periplasmic amino acid-binding proteins.

calcium-sensing receptor, which is a member of the
family C receptors within the G-protein coupled receptor
superfamily. Ligand-binding domain of the CaSR
calcium-sensing receptor, which is a member of the
family C receptors within the G-protein coupled receptor
superfamily. CaSR provides feedback control of
extracellular calcium homeostasis by responding
sensitively to acute fluctuations in extracellular
ionized Ca2+ concentration. This ligand-binding domain
has homology to the bacterial leucine-isoleucine-valine
binding protein (LIVBP) and a leucine binding protein
(LBP). CaSR is widely expressed in mammalian tissues and
is active in tissues that are not directly involved in
extracellular calcium homeostasis. Moreover, CaSR
responds to aromatic, aliphatic, and polar amino acids,
but not to positively charged or branched chain amino
acids, which suggests that changes in plasma amino acid
levels are likely to modulate whole body calcium
metabolism. Additionally, the family C GPCRs includes at
least two receptors with broad-spectrum amino
acid-sensing properties: GPRC6A which recognizes basic
and various aliphatic amino acids, its gold-fish homolog
the 5.24 chemoreceptor, and a specific taste receptor
(T1R) which responds to aliphatic, polar, charged, and
branched amino acids, but not to aromatic amino acids.

periplasmic-binding proteins of ATP-binding cassette
transporter-like systems. This CD includes members of
the family C of G-protein coupled receptors and their
close homologs, the type I periplasmic-binding proteins
of ATP-binding cassette transporter-like systems. The
family C GPCR includes glutamate/glycine-gated ion
channels such as the NMDA receptor, G-protein-coupled
receptors, metabotropic glutamate, GABA-B, calcium
sensing, phermone receptors, and atrial natriuretic
peptide-guanylate cyclase receptors. The glutamate
receptors that form cation-selective ion channels,
iGluR, can be classified into three different subgroups
according to their binding-affinity for the agonists
NMDA (N-methyl-D-asparate), AMPA
(alpha-amino-3-dihydro-5-methyl-3-oxo-4-
isoxazolepropionic acid), and kainate. L-glutamate is a
major neurotransmitter in the brain of vertebrates and
acts through either mGluRs or iGluRs. mGluRs subunits
possess seven transmembrane segments and a large
N-terminal extracellular domain. ABC-type
leucine-isoleucine-valine-binding protein (LIVBP) is a
bacterial periplasmic binding protein that has homology
with the amino-terminal domain of the glutamate-receptor
ion channels (iGluRs). The extracellular regions of
iGluRs are made of two PBP-like domains in tandem, a
LIVBP-like domain that constitutes the N terminus -
which is included in this CD - followed by a domain
related to lysine-arginine-ornithine-binding protein
(LAOBP) that belongs to the type II periplasmic binding
fold protein superfamily. The uncharacterized
periplasmic components of various ABC-type transport
systems are included in this group.

>gnl|CDD|107248 cd01391, Periplasmic_Binding_Protein_Type_1, Type 1 periplasmic
binding fold superfamily. Type 1 periplasmic binding
fold superfamily. This model and hierarchy represent the
ligand binding domains of the LacI family of
transcriptional regulators, periplasmic binding proteins
of the ABC-type transport systems, the family C
G-protein couples receptors (GPCRs), membrane bound
guanylyl cyclases including the family of natriuretic
peptide receptors (NPRs), and the N-terminal
leucine/isoleucine/valine- binding protein (LIVBP)-like
domains of the ionotropic glutamate receptors (iGluRs).
In LacI-like transcriptional regulator and the bacterial
periplasmic binding proteins the ligands are
monosaccharides including lactose, ribose, fructose,
xylose, arabinose, galactose/glucose, and other sugars,
with a few exceptions. Periplasmic sugar binding
proteins are one of the components of ABC transporters
and are involved in the active transport of
water-soluble ligands. The LacI family of proteins
consists of transcriptional regulators related to the
lac repressor. In this case, the sugar binding domain
binds a sugar which changes the DNA binding activity of
the repressor domain. The periplasmic binding proteins
are the primary receptors for chemotaxis and transport
of many sugar based solutes. The core structures of
periplasmic binding proteins are classified into two
types, and they differ in number and order of beta
strands: type 1 has six beta strands, while type 2 has
five beta strands per sub-domain. These two structural
folds are thought to be distantly related via a common
ancestor. Notably, while the N-terminal LIVBP-like
domain of iGluRs belongs to the type 1
periplasmic-binding fold protein superfamily, the
glutamate-binding domain of the iGluR is structurally
similar to the type 2 periplasmic-binding fold.

domain of the ionotropic glutamate receptors, all of
which are structurally similar and related to the
periplasmic-binding fold type I family. The family C
GPCRs consist of metabotropic glutamate receptor (mGluR)
receptors, a calcium-sensing receptor (CaSR),
gamma-aminobutyric receptors (GABAb), the promiscuous
L-alpha-amino acid receptor GPR6A, families of taste and
pheromone receptors, and orphan receptors. Truncated
splicing variants of the orphan receptors are not
included in this CD. The family C GPCRs are activated by
endogenous agonists such as amino acids, ions, and sugar
based molecules. Their amino terminal ligand-binding
region is homologous to the bacterial
leucine-isoleucine-valine binding protein (LIVBP) and a
leucine binding protein (LBP). The ionotropic glutamate
receptors (iGluRs) have an integral ion channel and are
subdivided into three major groups based on their
pharmacology and structural similarities: NMDA
receptors, AMPA receptors, and kainate receptors. The
family of membrane bound guanylyl cyclases is further
divided into three subfamilies: the ANP receptor
(GC-A)/C-type natriuretic peptide receptor (GC-B), the
heat-stable enterotoxin receptor (GC-C)/sensory organ
specific membrane GCs such as retinal receptors (GC-E,
GC-F), and olfactory receptors (GC-D and GC-G).

subtype of glutamate receptors. N-terminal
leucine/isoleucine/valine-binding protein (LIVBP)-like
domain of the ionotropic N-methyl-d-asparate (NMDA)
subtype of glutamate receptors. While this N-terminal
domain belongs to the periplasmic-binding fold type I
superfamily, the glutamate-binding domain of the iGluR
is structurally homologous to the periplasmic-binding
fold type II. The LIVBP-like domain of iGluRs is thought
to play a role in the initial assembly of iGluR
subunits, but it is not well understood how this domain
is arranged and functions in intact iGluR. The function
of the NMDA subtype receptor serves critical functions
in neuronal development, functioning, and degeneration
in the mammalian central nervous system. The functional
NMDA receptor is a heterotetramer comprising two NR1 and
two NR2 (A, B, C, and D) or NR3 (A and B) subunits. The
receptor controls a cation channel that is highly
permeable to monovalent ions and calcium and exhibits
voltage-dependent inhibition by magnesium. Dual
agonists, glutamate and glycine, are required for
efficient activation of the NMDA receptor. Among NMDA
receptor subtypes, the NR2B subunit containing receptors
appear particularly important for pain perception; thus
NR2B-selective antagonists may be useful in the
treatment of chronic pain.

homology with a family of pentose/hexose sugar-binding
proteins of the type I periplasmic binding protein
superfamily, which consists of two domains connected by
a three-stranded hinge. The substrate specificity of
this group is not known, but it is predicted to be
involved in the transport of sugar-containing molecules
and chemotaxis.

domain of ABC (Atpase Binding Cassette)-type active
transport systems that are involved in the transport of
all three branched chain aliphatic amino acids (leucine,
isoleucine and valine). This subgroup includes the type
I periplasmic ligand-binding domain of ABC (Atpase
Binding Cassette)-type active transport systems that are
involved in the transport of all three branched chain
aliphatic amino acids (leucine, isoleucine and valine).
This subgroup also includes a leucine-specific binding
protein (or LivK), which is very similar in sequence and
structure to leucine-isoleucine-valine binding protein
(LIVBP). ABC-type active transport systems are
transmembrane proteins that function in the transport of
diverse sets of substrates across extra- and
intracellular membranes, including carbohydrates, amino
acids, inorganic ions, dipeptides and oligopeptides,
metabolic products, lipids and sterols, and heme, to
name a few.

>gnl|CDD|188733 cd09347, LIM4_FHL, The fourth LIM domain of Four and a half LIM
domains protein (FHL). The fourth LIM domain of Four
and a half LIM domains protein (FHL): LIM-only protein
family consists of five members, designated FHL1, FHL2,
FHL3, FHL5 and LIMPETin. The first four members are
composed of four complete LIM domains arranged in tandem
and an N-terminal single zinc finger domain with a
consensus sequence equivalent to the C-terminal half of
a LIM domain. LIMPETin is an exception, containing six
LIM domains. FHL1, 2 and 3 are predominantly expressed
in muscle tissues, and FHL5 is highly expressed in male
germ cells. FHL proteins exert their roles as
transcription co-activators or co-repressors through a
wide array of interaction partners. For example, FHL1
binds to Myosin-binding protein C, regulating myosin
filament formation and sarcomere assembly. FHL2 has
shown to interact with more than 50 different proteins,
including receptors, structural proteins, transcription
factors and cofactors, signal transducers, splicing
factors, DNA replication and repair enzymes, and
metabolic enzymes. FHL3 interacts with many
transcription factors, such as CREB, BKLF/KLF3, CtBP2,
MyoD, and MZF_1. FHL5 is a tissue-specific coactivator
of CREB/CREM family transcription factors. LIM domains
are 50-60 amino acids in size and share two
characteristic zinc finger motifs. The two zinc fingers
contain eight conserved residues, mostly cysteines and
histidines, which coordinately bond to two zinc atoms.
LIM domains function as adaptors or scaffolds to support
the assembly of multimeric protein complexes.

leucine/isoleucine/valine-binding protein (LIVBP)-like
domain of the AMPA receptor. N-terminal
leucine/isoleucine/valine-binding protein (LIVBP)-like
domain of the AMPA
(alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic
acid) receptor, a member of the glutamate-receptor ion
channels (iGluRs). AMPA receptors are the major
mediators of excitatory synaptic transmission in the
central nervous system. While this N-terminal domain
belongs to the periplasmic-binding fold type I
superfamily, the glutamate-binding domain of the iGluR
is structurally homologous to the periplasmic-binding
fold type II. The LIVBP-like domain of iGluRs is thought
to play a role in the initial assembly of iGluR
subunits, but it is not well understood how this domain
is arranged and functions in intact iGluR. AMPA
receptors consist of four types of subunits (GluR1,
GluR2, GluR3, and GluR4) which combine to form a
tetramer and play an important roles in mediating the
rapid excitatory synaptic current.

Serine/Threonine Kinase, Atypical Protein Kinase C zeta.
Serine/Threonine Kinases (STKs), Atypical Protein
Kinase C (aPKC) subfamily, zeta isoform, catalytic (c)
domain. STKs catalyze the transfer of the
gamma-phosphoryl group from ATP to serine/threonine
residues on protein substrates. The aPKC subfamily is
part of a larger superfamily that includes the catalytic
domains of other protein STKs, protein tyrosine kinases,
RIO kinases, aminoglycoside phosphotransferase, choline
kinase, and phosphoinositide 3-kinase. PKCs are
classified into three groups (classical, atypical, and
novel) depending on their mode of activation and the
structural characteristics of their regulatory domain.
aPKCs only require phosphatidylserine (PS) for
activation. There are two aPKC isoforms, zeta and iota.
PKC-zeta plays a critical role in activating the glucose
transport response. It is activated by glucose, insulin,
and exercise through diverse pathways. PKC-zeta also
plays a central role in maintaining cell polarity in
yeast and mammalian cells. In addition, it affects actin
remodeling in muscle cells.
