This antibody does not cross-react with Prdx2 protein. Species Reactivity: Human, Mouse, Rat, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Arg110 of human Prdx1 protein. Background Prdx1 belongs to a family of non-seleno peroxidases that function as H O scavengers. All 6 Prdx isoforms share a conserved N-terminal cysteine (Cys51) that is oxidized by H O to form cysteine-sulfenic acid (Cys51-SOH) and, in turn, reacts with Cys172-SH of another Prdx protein, forming a disulfide dimer and protecting it from degradation (1-3). Abnormally high levels of H O cause Prdx1 to form an oligomeric chaperone that loses its peroxidase activity (4). Prdx family members have been reported to bind to JNK and c-Abl and regulate their kinase activity (5,6). Prdx1 was shown to bind to PTEN and regulate its phosphatase activity in conditions of mild or no cellular stress, hence preventing Akt-driven transformation by protecting PTEN from oxidation-induced inactivation (7).
