Summary: Enables G protein-coupled neurotransmitter receptor activity involved in regulation of postsynaptic cytosolic calcium ion concentration and G protein-coupled receptor activity involved in regulation of postsynaptic membrane potential. Involved in several processes, including positive regulation of MAPK cascade; regulation of sensory perception of pain; and synaptic signaling via neuropeptide. Acts upstream of or within L-glutamate import across plasma membrane and cellular response to electrical stimulus. Located in dendrite; nucleus; and postsynaptic density. Is active in Schaffer collateral - CA1 synapse and glutamatergic 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NM_001114333.3 → NP_001107805.1 metabotropic glutamate receptor 1 isoform beta precursor

See identical proteins and their annotated locations for NP_001107805.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) encodes the shorter isoform (beta). Isoform beta has a different subcellular distribution than isoform alpha and may be functionally distinct due to differential G-protein coupling of its novel C-terminal sequence. Variants 2 and 4 both encode the same isoform (beta).
