    Protocol

    Specificity / Sensitivity

    Phospho-Prdx1 (Tyr194) (D1T9C) Rabbit mAb recognizes endogenous levels of Prdx1 protein only when phosphorylated at Tyr194. This antibody may cross react with other activated receptor tyrosine kinases including EGFR.

    Species Reactivity:

    Human

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Mouse, Rat

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr194 of human Prdx1 protein.

    Background

    Prdx1 belongs to a family of non-seleno peroxidases that function as H2O2 scavengers. All 6 Prdx isoforms share a conserved N-terminal cysteine (Cys51) that is oxidized by H2O2 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 H2O2 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).
    The transient phosphorylation of Prdx1 at Tyr194 leads to inactivation of Prdx1 that in turn promotes localized hydrogen peroxide accumulation (8). Evidence suggests that the Tyr194 phosphorylation of Prdx1 is prominent at the wound edge during repair of cutaneous injury in mice (8,9).
