Summary: Involved in regulation of postsynaptic cytosolic calcium ion concentration and regulation of postsynaptic membrane neurotransmitter receptor levels. Acts upstream of or within long-term synaptic depression. Located in synapse. Is active in cerebellar granule cell to Purkinje cell synapse; parallel fiber to Purkinje cell synapse; and postsynaptic density, intracellular component. Orthologous to human GRID2IP (Grid2 interacting protein). [provided by Alliance of Genome Resources, Nov 2024]

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.
