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. Has a role in telomere silencing, which is the repression of chromatin structure which leads to a stop in the transcription of nearby genes. Also has a role in the regulation of telomere length. Acts as an alkyl-hydroperoxide reductase in the nucleus during post-diauxic growth. Preferentially reduces alkyl-hydroperoxides rather than hydrogen peroxide. Acts as an antioxidant necessary for stationary phase survival.
