TIGAR, also known as TP53-induced glycolysis and apoptosis regulator, is a 270 amino acid protein induced by the p53 tumor suppressor pathway that functions to protect against oxidative stress. TIGAR specifically functions to block glycolysis, leading the pathway to the pentose phosphate shunt and decreasing the intracellular concentration of reactive oxygen species. These facts indicate that TIGAR may act to modulate the apoptotic response to p53, thereby allowing cells to survive mild or transient stresses. Recombinant human TIGAR protein, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography techniques.
