Phosphatidylinositol 4-phosphate (PI4P) is the most abundant monophosphoinositide in eukaryotic cells. Humans have four phosphatidylinositol 4-kinases (PI4Ks) that synthesize PI4P, among which are PI4K II beta and PI4K II alpha. In this study, two crystal structures are presented: the structure of human PI4K II beta and the structure of PI4K II alpha containing a nucleoside analogue. The former, a complex with ATP, is the first high-resolution (1.9 angstrom) structure of a PI4K. These structures reveal new details such as high conformational heterogeneity of the lateral hydrophobic pocket of the C-lobe and together provide a structural basis for isoform-specific inhibitor design.
