Description: Catalysis of the reaction: ATP + a phosphatidylinositol = ADP + a phosphatidylinositol 3-phosphate. This reaction is the addition of a phosphate group to an inositol lipid at the 3' position of the inositol ring to generate the 3-phosphoinositides: phosphatidylinositol-3-phosphate [PI(3)P], phosphatidylinositol-3,4-bisphosphate [PI(3,4)P2] and phosphatidylinositol-3,4,5-trisphosphate [PI(3,4,5)P3].
