Description

Predicted to have inositol 1,4,5 trisphosphate binding activity and inositol 1,4,5-trisphosphate-sensitive calcium-release channel activity. Predicted to be involved in calcium ion transmembrane transport. Predicted to localize to endoplasmic reticulum and integral component of membrane. Human ortholog(s) of this gene implicated in Gillespie syndrome; spinocerebellar ataxia type 15; and spinocerebellar ataxia type 29. Is expressed in Purkinje cell; cerebellum; granule cell; hindbrain; and optic tectum. Orthologous to human ITPR1 (inositol 1,4,5-trisphosphate receptor type 1).
