May constitute a glutathione peroxidase-like protective system against peroxide damage in sperm membrane lipids. Since the purified porcine enzyme has very little activity towards hydrogen peroxide or organic hydroperoxides the protective effect is not likely to be exerted by its enzymatic activity. Instead, may protect sperm from premature acrosome reaction in the epididymis by binding to lipid peroxides, which might otherwise interact with phospholipase A2 and induce the acrosome reaction. GPX5 Protein, Pig, Recombinant (His & Myc) is expressed in yeast with N-6xHis and C-Myc tag. The predicted molecular weight is 26.1 kDa and the accession number is O18994.
