Summary: Enables several functions, including alcohol binding activity; identical protein binding activity; and inositol 1,4,5-trisphosphate-gated calcium channel activity. Involved in G protein-coupled receptor signaling pathway; cellular response to cAMP; and positive regulation of cytosolic calcium ion concentration. Located in several cellular components, including apical plasma membrane; brush border; and nuclear outer membrane. Is active in endoplasmic reticulum membrane and presynapse. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease and type 1 diabetes mellitus. Orthologous to human ITPR3 (inositol 1,4,5-trisphosphate receptor type 3).

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.
