Ligand-binding domain of GABAb receptors which are metabotropic transmembrane receptors for gamma-aminobutyric acid (GABA). GABA is the major inhibitory neurotransmitter in the mammalian CNS and like glutamate and other transmitters acts via both ligand gated ion channels (GABAa receptors) and G-protein coupled receptors (GABAb). GABAa receptors are members of the ionotropic receptor superfamily which includes alpha-adrenergic and glycine receptors. The GABAb receptor is a member of a receptor superfamily which includes the mGlu receptors. The GABAb receptor is coupled to G alpha_i proteins and activation causes a decrease in calcium an increase in potassium membrane conductance and inhibition of cAMP formation. The response is thus inhibitory and leads to hyperpolarization and decreased neurotransmitter release for example.

This family includes extracellular ligand binding domains of a wide range of receptors. This family also includes the bacterial amino acid binding proteins of known structure.

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.
rpsblast_cdd gnl|CDD|153137 43 302 + 260 Gaps:26 85.23 298 24.80 5e-28 cd06269 PBP1_glutamate_receptors_like Family C G-protein couples receptors (GPCRs) membrane bound guanylyl cyclases such as the family of natriuretic peptide receptors (NPRs) and the N-terminal leucine/isoleucine/valine- binding protein (LIVBP)-like domain of the ionotropic glutamate receptors. This CD represents the ligand-binding domain of the family C G-protein couples receptors (GPCRs) membrane bound guanylyl cyclases such as the family of natriuretic peptide receptors (NPRs) and the N-terminal leucine/isoleucine/valine- binding protein (LIVBP)-like 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).

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.
