Gene Gene information from NCBI Gene database.
Entrez ID 3708
Gene name Inositol 1,4,5-trisphosphate receptor type 1
Gene symbol ITPR1
Synonyms (NCBI Gene)
ACVCLA4INSP3R1IP3RIP3R1PPP1R94SCA15SCA16SCA29
Chromosome 3
Chromosome location 3p26.1
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
