COMMENT     REVIEWED REFSEQ: This record has been curated by NCBI staff. The
            reference sequence was derived from DA060305.1, DB260851.1,
            D26070.1, AK293752.1, AK294594.1, AB208868.1, BQ006717.1 and
            On Nov 26, 2009 this sequence version replaced NP_002213.4.
            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. [provided by RefSeq,
            Nov 2009].
            Transcript Variant: This variant (2) lacks an alternate in-frame
            exon in the central coding region, compared to variant 1, resulting
            in a shorter isoform (2), compared to isoform 1.
            Publication Note:  This RefSeq record includes a subset of the
            publications that are available for this gene. Please see the Gene
            record to access additional publications.
