Inositol phosphate

Phosphate group

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:


  • Functions 1
    • Inositol triphosphate 1.1
    • Other 1.2
  • References 2

Inositol triphosphate

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


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