Substance Name: Inositol 1,4,5-trisphosphate
RN: 85166-31-0
UNII: MU34XVK5NR
InChIKey: MMWCIQZXVOZEGG-HOZKJCLWSA-N
Note
- 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. Inositol 1,4,5-trisphosphate 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.
