Recombinant Human Metabotropic glutamate receptor 4 (GRM4), Truncated

Uniprot Id

Q14833

Target Species

Human

Target Name

GRM4

Target Full Name

Metabotropic glutamate receptor 4

Target Function

G-protein coupled receptor for glutamate. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors. Signaling inhibits adenylate cyclase activity.

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

G-protein coupled receptor 3 family

Target Tissue Specificity

Strongly expressed in the cerebellum. Expressed at low levels in hippocampus, hypothalamus and thalamus. No expression detected in liver.

Target Synonyms

Glutamate receptor metabotropic 4; GPRC1D; Grm4; GRM4_HUMAN; Metabotropic glutamate receptor 4; mGlu4; mGluR4

Target Background

L-glutamate is the major excitatory neurotransmitter in the central nervous system and activates both ionotropic and metabotropic glutamate receptors. Glutamatergic neurotransmission is involved in most aspects of normal brain function and can be perturbed in many neuropathologic conditions. The metabotropic glutamate receptors are a family of G protein-coupled receptors, that have been divided into 3 groups on the basis of sequence homology, putative signal transduction mechanisms, and pharmacologic properties. Group I includes GRM1 and GRM5 and these receptors have been shown to activate phospholipase C. Group II includes GRM2 and GRM3 while Group III includes GRM4, GRM6, GRM7 and GRM8. Group II and III receptors are linked to the inhibition of the cyclic AMP cascade but differ in their agonist selectivities. Several transcript variants encoding different isoforms have been found for this gene.
