Summary
Enables several functions, including inositol 1,4,5 trisphosphate binding activity; inositol 1,4,5-trisphosphate receptor activity involved in regulation of postsynaptic cytosolic calcium levels; and protein homodimerization activity. Involved in several processes, including G protein-coupled receptor signaling pathway; positive regulation of insulin secretion; and protein homotetramerization. Acts upstream of or within several processes, including calcium ion transport; endoplasmic reticulum calcium ion homeostasis; and voluntary musculoskeletal movement. Located in endoplasmic reticulum; nucleus; and postsynaptic density. Part of calcineurin complex. Is active in Schaffer collateral - CA1 synapse. Is expressed in several structures, including brain; brown fat; genitourinary system; heart; and hemolymphoid system. Human ortholog(s) of this gene implicated in Gillespie syndrome; spinocerebellar ataxia type 15; and spinocerebellar ataxia type 29. Orthologous to human ITPR1 (inositol 1,4,5-trisphosphate receptor type 1). [provided by Alliance of Genome Resources, Dec 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.
