描述
Diphosphoinositol pentakisphosphate (InsP7) contains an inositol polyphosphate that contains a pyrophosphate bond. InsP7 is formed from inositol hexakisphosphate (InsP6) by a family of three inositol hexakisphosphate kinases (InsP6K). (PMID: 15533939). It is an intracellular signaling molecule that regulates many cellular processes including endocytosis, vesicle trafficking, apoptosis, and DNA repair. (PMID 15316027) [HMDB]
