Inositol polyphosphate kinase (IPK) is a family of enzymes that have a similar 3-dimensional structure. All members of the family catalyze the transfer of phosphate groups from ATP to various inositol phosphates. Members of the family include inositol-polyphosphate multikinases, inositol-hexakisphosphate kinases, inositol-trisphosphate 3-kinases, and inositol-pentakisphosphate 2-kinase, which is more distantly related to the others
