Automated description from the Alliance of Genome Resources (Release 4.0)
Enables G protein-coupled neurotransmitter receptor activity involved in regulation of postsynaptic cytosolic calcium ion concentration. Involved in several processes, including positive regulation of MAPK cascade; regulation of sensory perception of pain; and sensory perception of pain. Acts upstream of or within L-glutamate import across plasma membrane and cellular response to electrical stimulus. Located in several cellular components, including dendrite; glutamatergic synapse; and postsynaptic density. Is active in Schaffer collateral - CA1 synapse. Is expressed in several structures, including appendicular skeleton; eye; nervous system; testis; and tongue. Used to study autosomal recessive spinocerebellar ataxia 13; skin melanoma; and uveal melanoma. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 13 and spinocerebellar ataxia 44. Orthologous to human GRM1 (glutamate metabotropic receptor 1).
