Modulation of phosphatidylinositol 4 phosphate levels by cabp7 controls cytokinesis in mammalian


Phosphatidylinositol 4-phosphate (PtdIns4P, PI-4-P, PI4P, or PIP) is a precursor of phosphatidylinositol (4,5)-bisphosphate. PtdIns4P is prevalent in the membrane of the Golgi apparatus.

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.
