Gene: Itpr1 (inositol 1,4,5-trisphosphate receptor, type 1) Rattus norvegicus
Symbol: Itpr1
Name: inositol 1,4,5-trisphosphate receptor, type 1
Description: Exhibits several functions, including identical protein binding activity; inositol 1,4,5-trisphosphate-sensitive calcium-release channel activity; and protein C-terminus binding activity. Involved in several processes, including cellular response to cAMP; generation of neurons; and liver regeneration. Localizes to several cellular components, including the GABA-ergic synapse; cytoplasm; and nuclear envelope. Used to study asthma. Biomarker of Huntington's disease; cardiac arrest; and transient cerebral ischemia. Human ortholog(s) of this gene implicated in spinocerebellar ataxia type 15 and spinocerebellar ataxia type 29. Orthologous to human ITPR1 (inositol 1,4,5-trisphosphate receptor type 1); PARTICIPATES IN acebutolol pharmacodynamics pathway; adrenergic beta receptor agonist and beta-blocker pharmacodynamics pathway; amiodarone pharmacodynamics pathway; INTERACTS WITH (RS)-amphetamine; (S)-10-[(DIMETHYLAMINO)METHYL]-4-ETHYL-4,9-DIHYDROXY-1H-PYRANO[3',4':6,7]INOLIZINO[1,2-B]-QUINOLINE-3,14(4H,12H)-DIONE; 11-CYCLOPROPYL-5,11-DIHYDRO-4-METHYL-6H-DIPYRIDO[3,2-B:2',3'-E][1,4]DIAZEPIN-6-ONE.
Type: protein-coding
RefSeq Status: REVIEWED
