Common Name1-phosphatidyl-1D-myo-inositol 4-phosphate
Description1-phosphatidyl-1D-myo-inositol 4-phosphate belongs to the class of organic compounds known as inositol phosphates. Inositol phosphates are compounds containing a phosphate group attached to an inositol (or cyclohexanehexol) moiety. Phosphatidylinositol-4-phosphate (PtdIns4P, PI-4-P, PI4P, or PIP) is a precursor of phosphatidylinositol (4,5)-bisphosphate. 1-phosphatidyl-1D-myo-inositol 4-phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). In humans, 1-phosphatidyl-1D-myo-inositol 4-phosphate is involved in mercaptopurine metabolism pathway. In the Golgi apparatus, PtdIns4P binds to the GTP-binding protein ARF and to effector proteins, including four-phosphate-adaptor protein 1 and 2 (FAPP1 and FAPP2). This three molecule complex recruits proteins that need to be carried to the cell membrane. There is now evidence that PI-4-P is capable of deforming lipid systems into tightly curved assemblies, this is consistent with similar behaviour observed in phosphatidylinositol. PtdIns4P is prevalent in the membrane of the Golgi apparatus.
