Purity > 85% as determined by SDS-PAGE. MW: 23.6kDa. Full Length of Mature Protein: 2-199aa. N-terminal 6xHis-tagged. Cricetulus griseus (Chinese hamster) (Cricetulus barabensis griseus). 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 H2O2. Reduces an intramolecular disulfide bond in GDPD5 that gates the ability to GDPD5 to drive postmitotic motor neuron differentiation.
