Description | Inositol phosphates are a family of water-soluble intracellular signalling molecules derived from membrane inositol phospholipids. They undergo a variety of complex interconversion pathways, and their levels are dynamically regulated within the cytosol in response to a variety of agonists. Their biological actions can be quite specific to particular inositol phosphates. D-myo-Inositol 3,4,5,6-tetrakisphosphate, also known as Ins(1,4,5,6)P4 is phosphorylated by inositolphosphate-multikinase (IMPK). Ins(1,4,5,6)P4 has been shown to regulate Cl- transport, to be a phosphoinositide 3-kinase antagonist, and to bind tightly to some pleckstrin homology domains. It may also contribute to transcriptional regulation (PMID: 16376887 , 10720331 , 8809047 , 9405634 ). |
