PRDX2 Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides and as sensor of hydrogen peroxide-mediated signaling events. Might participate in the signaling cascades of growth factors and tumor necrosis factor-alpha by regulating the intracellular concentrations of H(2)O(2). Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
