UniprotKB/SwissProt ID: P38013 (P38013)
Gene Name:
AHP1
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: 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. Preferentially eliminates organic peroxides rather than hydrogen peroxide (PubMed:10391912, PubMed:10681558, PubMed:9988687). Relays alkyl hydroperoxides as a signal to the transcription factor CAD1/YAP2 by inducing the formation of intramolecular disulfide bonds in CAD1, which causes its nuclear accumulation and activation (PubMed:20145245). Involved in cellular Mn(2+) homeostasis (PubMed:10635552)
