Gene: ITPR1
Alternate names for this Gene: ACV|CLA4|INSP3R1|IP3R|IP3R1|PPP1R94|SCA15|SCA16|SCA29
Gene Summary: This gene encodes an intracellular receptor for inositol 1,4,5-trisphosphate. Upon stimulation by inositol 1,4,5-trisphosphate, this receptor mediates calcium release from the endoplasmic reticulum. Mutations in this gene cause spinocerebellar ataxia type 15, a disease associated with an heterogeneous group of cerebellar disorders. Multiple transcript variants have been identified for this gene.
Gene is located in Chromosome: 3
Location in Chromosome : 3p26.1
Description of this Gene: inositol 1,4,5-trisphosphate receptor type 1
Type of Gene: protein-coding
