DE   1-phosphatidylinositol-4-phosphate 5-kinase.
AN   Diphosphoinositide kinase.
AN   Phosphatidylinositol 4-phosphate kinase.
AN   Phosphatidylinositol-4-phosphate 5-kinase.
AN   PIP kinase.
AN   PtdIns(4)P-5-kinase.
AN   Type I PIP kinase.
CA   ATP + 1-phosphatidyl-1D-myo-inositol 4-phosphate = ADP + 1-phosphatidyl-
CA   1D-myo-inositol 4,5-bisphosphate.
CC   -!- This enzyme can also phosphorylate PtdIns3P in the 4-position,
CC       and PtdIns, PtdIns3P and PtdIns(3,4)P(2) in the 5-position in vitro,
CC       but to a lesser extent.
CC   -!- The last of these reactions occurs in vivo and is physiologically
CC       relevant.
