Summary: Enables group II metabotropic glutamate receptor activity and scaffold protein binding activity. Involved in several processes, including behavioral response to nicotine; positive regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction; and regulation of amine transport. Located in astrocyte projection and axon. Is active in presynaptic membrane. Used to study heroin dependence. Biomarker of schizophrenia. Orthologous to human GRM2 (glutamate metabotropic receptor 2). [provided by Alliance of Genome Resources, Dec 2024]

studies illustrate the significant contribution of mGluR2 to the antipsychotic-like, sleep and EEG effects of drugs acting on group II mGluRs; however, we also provide evidence of a role for mGluR3 activity in the control of sleep and wake cortical theta and gamma oscillations

Whereas both glutamate metabotropic receptor 2 and glutamate metabotropic receptor 4 couple to G proteins, G protein activation is mediated by mGlu4 heptahelical domain (HD) exclusively in glutamate metabotropic receptor 2-4 heterodimers.
Title: Allosteric control of an asymmetric transduction in a G protein-coupled receptor heterodimer.
Although assumed to form exclusive homodimers, 16 possible heterodimeric mGluRs have been proposed but their existence in native cells remains elusive. Study identified mGlu2-4 specific pharmacological fingerprints that were also observed in a neuronal cell line and in lateral perforant path terminals naturally expressing mGlu2 and mGlu4. Results show the existence of mGlu2-4 heterodimers in native cells.

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.
