At the Golgi membrane, phosphatidylinositol-4-phosphate 3-kinase C2 domain-containing subunit alpha (PIK3C2A) (Domin et al. 2000, Arcaro et al. 2000) and phosphatidylinositol-4-phosphate 3-kinase C2 domain-containing subunit gamma (PIK3C2G) (Ono et al. 1998, Rozycka et al. 1998, Misawa et al. 1998) phosphorylate phosphatidylinositol 4-phosphate (PI4P) to phosphatidylinositol 3,4-bisphosphate (PI(3,4)P2). PIK3C2G phosphorylates phosphatidylinositol (PI) and PI4P but not phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2).
