GRM8 is a 7 transmembrane (7TM) receptor belonging to the family 3 (also known as family C) of the G-protein-coupled receptors (GPCRs). Structurally they are composed of 4 elements; an N-terminal signal peptide; a large hydrophilic extracellular agonist-binding region; a region containing 7TM domains; and a C-terminal cytoplasmic domain of variable length.  Family 3 members include the metabotropic glutamate receptors (mGluRs), the extracellular calcium-sensing receptors (CASRs), the gamma-amino-butyric acid (GABA) type B receptors, and the vomeronasal type-2 receptors.  These GPCRs regulate many important physiological processes and many of them are promising targets for drug development. mGluRs are distinct from the ionotropic glutamate receptors and are coupled to G-proteins to stimulate the inositol phosphate/Ca2+ signaling pathway. At least 8 subtypes of mGluR (MGR1-8) have been identified and they differ in their agonist pharmacology and signal transduction pathways.  They can be divided into 3 groups: 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. GRM8 may participate in the central action of glutamate in the CNS, such as long-term potentiation and depression. 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.
