Phosphatidylinositol-4-phosphate-binding protein that may antagonize the action of GOLPH3 which is required for the process of vesicle budding at the Golgi and anterograde transport to the plasma membrane.
Subcellular locations: Golgi apparatus, Golgi stack membrane, Golgi apparatus, Trans-Golgi network membrane
Phosphatidylinositol 4-phosphate (PtdIns4P)-binding mediates recruitment to Golgi membranes.
