IHPK2

Inositol hexakisphosphate kinase 2 is an enzyme that in humans is encoded by the IP6K2 gene.
This gene encodes a protein that belongs to the inositol phosphokinase family. This protein is likely responsible for the conversion of inositol hexakisphosphate to diphosphoinositol pentakisphosphate. It may also convert 1,3,4,5,6-pentakisphosphate to PP-InsP4 and affect the growth suppressive and apoptotic activities of interferon-beta in some ovarian cancers. Alternative splicing results in multiple transcript variants encoding different isoforms.
