CC -!- FUNCTION: Thiol-specific peroxidase that catalyzes the reduction of
CC hydrogen peroxide and organic hydroperoxides to water and alcohols,
CC respectively. Plays a role in cell protection against oxidative stress
CC by detoxifying peroxides and as sensor of hydrogen peroxide-mediated
CC signaling events. Might participate in the signaling cascades of growth
CC factors and tumor necrosis factor-alpha by regulating the intracellular
CC concentrations of H(2)O(2). {ECO:0000269|PubMed:9497357}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-dithiol + a hydroperoxide = [thioredoxin]-
CC disulfide + an alcohol + H2O; Xref=Rhea:RHEA:62620, Rhea:RHEA-

CC Evidence={ECO:0000269|PubMed:8554614, ECO:0000269|PubMed:9497357};
CC -!- SUBUNIT: Homodimer; disulfide-linked, upon oxidation (PubMed:27892488).
CC 5 homodimers assemble to form a ring-like decamer (PubMed:27892488).
CC Interacts with TIPIN (PubMed:17141802). {ECO:0000269|PubMed:17141802,

CC IsoId=P32119-1; Sequence=Displayed;
CC Name=2;
CC IsoId=P32119-2; Sequence=VSP_042924;
CC -!- PTM: The enzyme can be inactivated by further oxidation of the cysteine
CC sulfenic acid (C(P)-SOH) to sulphinic acid (C(P)-SO2H) instead of its
CC condensation to a disulfide bond. It can be reactivated by forming a
CC transient disulfide bond with sulfiredoxin SRXN1, which reduces the
CC cysteine sulfinic acid in an ATP- and Mg-dependent manner.
CC {ECO:0000250|UniProtKB:Q06830, ECO:0000269|PubMed:11904290,
CC ECO:0000269|PubMed:12853451}.
CC -!- MISCELLANEOUS: The active site is a conserved redox-active cysteine
CC residue, the peroxidatic cysteine (C(P)), which makes the nucleophilic
CC attack on the peroxide substrate. The peroxide oxidizes the C(P)-SH to
CC cysteine sulfenic acid (C(P)-SOH), which then reacts with another
CC cysteine residue, the resolving cysteine (C(R)), to form a disulfide
CC bridge. The disulfide is subsequently reduced by an appropriate
CC electron donor to complete the catalytic cycle. In this typical 2-Cys
CC peroxiredoxin, C(R) is provided by the other dimeric subunit to form an
CC intersubunit disulfide. The disulfide is subsequently reduced by
CC thioredoxin. {ECO:0000305|PubMed:27892488}.
CC -!- MISCELLANEOUS: [Isoform 2]: Due to intron retention. May be produced at
CC very low levels due to a premature stop codon in the mRNA, leading to
CC nonsense-mediated mRNA decay. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
CC {ECO:0000305}.
