Anti-IP6K2 [Clone 4F10] - 100 μg

Inositol hexakisphosphate kinase 2 (IP6K2) catalyzes the production of diphosphoinositol pentakisphosphate (IP7) and has a role as a proapoptotic gene sensitizing cancer cells to apoptosis by cell stressors and anticancer drugs all of which depend on IP6K2 catalytic activity. IP6K2 is located in the 3p21.31 chromosomal region, which often undergoes allele loss in a variety of human cancers. Some heat shock proteins, especially Hsp90, can be antiapoptotic and the targets of anticancer drugs. Hsp90 binds IP6K2 and inhibits its catalytic activity. Drugs and selective mutations that abolish HSP90-IP6K2 binding elicit activation of IP6K2, leading to cell death. Thus, the prosurvival actions of HSP90 reflect the inhibition of IP6K2, suggesting that selectively blocking this interaction could provide effective and safer modes of chemotherapy.
