Inositol phosphates are a group of mono- to polyphosphorylated inositols. They play crucial roles in diverse cellular functions, such as cell growth, apoptosis, cell migration, endocytosis, and cell differentiation. The group comprises:

• inositol monophosphate
• inositol trisphosphate
• inositol pentakisphosphate
• inositol hexaphosphate

[edit] Functions

[edit] Inositol triphosphate

Inositol trisphosphates act on the inositol triphosphate receptor to release calcium into the cytoplasm. Further reading: Function of calcium in humans

[edit] Other

Inositol tetra-, penta-, and hexa-phosphates have been implicated in gene expression^[1] and Steger^[2] (both in Science Magazine).
