>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.

>gnl|CDD|107359 cd06364, PBP1_CaSR, 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. 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.

>gnl|CDD|107347 cd06352, PBP1_NPR_GC_like, Ligand-binding domain of membrane
guanylyl-cyclase receptors. Ligand-binding domain of
membrane guanylyl-cyclase receptors. Membrane guanylyl
cyclases (GC) have a single membrane-spanning region and
are activated by endogenous and exogenous peptides. This
family can be divided into three major subfamilies: the
natriuretic peptide receptors (NPRs), sensory
organ-specific membrane GCs, and the
enterotoxin/guanylin receptors. The binding of peptide
ligands to the receptor results in the activation of the
cytosolic catalytic domain. Three types of NPRs have
been cloned from mammalian tissues: NPR-A/GC-A, NPR-B/
GC-B, and NPR-C. In addition, two of the GCs, GC-D and
GC-G, appear to be pseudogenes in humans. Atrial
natriuretic peptide (ANP) and brain natriuretic peptide
(BNP) are produced in the heart, and both bind to the
NPR-A. NPR-C, also termed the clearance receptor, binds
each of the natriuretic peptides and can alter
circulating levels of these peptides. The ligand binding
domain of the NPRs exhibits strong structural similarity
to the type I periplasmic binding fold protein family.

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.
