Шаблон:Short description Шаблон:Infobox protein family Inositol polyphosphate kinase (IPK) is a family of enzymes[1] 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[2][3]

The discovery of the IPK family occurred in 1999, when a combination of biochemistry, sequence analysis, and genetics led to the classification of a family of inositol polyphosphate kinases. [4][5] In 2005, the first crystal structures of an IPK family protein were published for ITPKA.[6][7]

Subsequently, structures of the inositol polyphosphate multikinase and various IP6 kinases have expanded our structural understanding for how each enzyme catalyzes its specific reaction(s).
