Glutathione peroxidase-like protein that protects cells from phospholipid hydroperoxides and nonphospholipid peroxides during oxidative stress. Plays an important role in the oxidative stress-induced response in the presence of Ca(2+). Has peroxidase activity using preferentially thioredoxin as a reducing power. The redox state of the mitochondrial GPX2 is regulated by TRX1 and TRX2 (cytoplasmic thioredoxin), and by TRX3 (mitochondrial matrix thioredoxin). Involved in sporulation. GPX2 Protein, S. cerevisiae, Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 23.4 kDa and the accession number is P38143.
