UniProtKB description: 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 (PubMed:10681558, PubMed:11741925, PubMed:15210711). Can act alternatively as peroxidase and molecular chaperone. Oxidative stress and heat shock exposure cause a reversible shift of the protein structure from low MW species to high MW complexes, triggering a peroxidase-to-chaperone functional switch. The chaperone function of the protein enhances resistance to heat shock (PubMed:15163410).
