Catalysis of the reaction: inositol tetrakisphosphate + ATP = inositol pentakisphosphate + ADP. Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to an alcohol group (acceptor). Catalysis of the phosphorylation of myo-inositol (1,2,3,5/4,6-cyclohexanehexol) or a phosphatidylinositol. Catalysis of the reaction: 1D-myo-inositol tetrakisphosphate + ATP = 1D-myo-inositol pentakisphosphate (containing 2-phosphate) + ADP.
