Phosphatidylinositol 4-phosphate

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.

[1] This three molecule complex recruits proteins that need to be carried to the cell membrane.

[2] There is now evidence that PI-4-P is capable of deforming lipid systems into tightly curved assemblies,[3][4] this is consistent with similar behaviour observed in phosphatidylinositol.
