Description

Predicted to enable inositol 1,4,5 trisphosphate binding activity and inositol 1,4,5-trisphosphate-gated calcium channel activity. Acts upstream of or within atrioventricular canal development; cranial skeletal system development; and determination of heart left/right asymmetry. Predicted to be located in endoplasmic reticulum and membrane. Is expressed in Purkinje cell; cerebellum; granule cell; hindbrain; and optic tectum. Used to study congenital heart disease. 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).
