Metabolite Identification
Common Namemyo-Inositol 1,4,5-trisphosphate
Descriptionmyo-Inositol 1,4,5-trisphosphate (CAS: 20298-95-7), also known as Ins(1,4,5)P3 or InsP3, is an intracellular messenger formed by the action of phospholipase C on phosphatidylinositol 4,5-bisphosphate, which is one of the phospholipids that make up the cell membrane (PMID: 22453946 ). It is released into the cytoplasm where it releases calcium ions from internal stores within the cell's endoplasmic reticulum. These calcium ions stimulate the activity of B kinase or calmodulin (PMID: 15189149 ). Its transient accumulation is due both to the enhanced metabolism via the Ca2+-calmodulin-sensitive Ins(1,4,5)P3 kinase, as well as a down-regulation of phosphatidylinositol 4,5-bisphosphate hydrolysis (PMID: 3041962 ). It is a major regulator of apoptotic signalling driving calcium (Ca2+) transients from the endoplasmic reticulum to mitochondria, thereby establishing a functional and physical link between these organelles. It also regulates autophagy through the interaction with Beclin 1 complex, and in particular, its inhibition/depletion strongly induces macroautophagy (PMID: 19325567 ). In addition, recent evidence suggests that the penetrating sperm delivers into mammalian eggs a novel isoform of phospholipase C (PLC), which promotes the formation of inositol 1,4,5-trisphosphate (PMID: 15362223 ).
