Name :
Recombinant Human IP6K1/IHPK1 Protein (His & GST Tag)
Biological Activity :
Background :
IP6K1 (Inositol Hexakisphosphate Kinase 1) is a Protein Coding gene. 2 alternatively spliced human isoforms have been reported. IHPK1 is an inositol hexaphosphate kinase (IHPK) protein that belongs to the inositol phosphokinase (IPK) family. IHPK proteins are likely responsible for the conversion of inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7/PP-InsP5). IHPK1 may also convert 1,3,4,5,6-pentakisphosphate (InsP5) to PP-InsP4 and affect the growth-suppressive and apoptotic activities of interferon-beta in some ovarian cancers. During cell death, IHPK1 activity is enhanced, and the intracellular InsP7 level is augmented. The distribution of IHPK1 or another predisposing gene affected by the position effect of translocation may explain the T2DM phenotype at least in this family.
