| Mgi Type | protein coding gene |
| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) 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). PHENOTYPE: Most homozygotes for a targeted null mutation die in utero, while survivors exhibit severe ataxia, seizures, and lethality by weaning age. Homozygotes for a spontaneous mutation exhibit a postnatal phenotype similar to that of knockout mutants. [provided by MGI curators] |
