Summary: Enables calcium channel regulator activity and group II metabotropic glutamate receptor activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within gene expression; intracellular glutamate homeostasis; and long-term synaptic depression. Located in neuron projection. Is active in glutamatergic synapse and postsynaptic membrane. Is expressed in brain; cerebellum internal granule cell layer; and telencephalon. Orthologous to human GRM2 (glutamate metabotropic receptor 2). [provided by Alliance of Genome Resources, Dec 2024]

Here we show that glutamate signals through metabotropic glutamate receptor 2 (mGluR2) to induce Erk phosphorylation in SC. mGluR2-elicited Erk phosphorylation requires ErbB2/3 receptor tyrosine kinase phosphorylation to limit the signaling cascade that promotes phosphorylation of Erk, but not Akt.

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.
