背景(Background)
The protein encoded by this gene is an antioxidant enzyme and belongs to the peroxiredoxin family. The protein is localized to the cytoplasm. Peroxidases of the peroxiredoxin family reduce hydrogen peroxide and alkyl hydroperoxides to water and alcohol with the use of reducing equivalents derived from thiol-containing donor molecules. This protein has been found to play a regulatory role in the activation of the transcription factor NF-kapMAB. [provided by RefSeq, Jul 2008],
功能
catalytic activity:2 R'-SH + ROOH = R'-S-S-R' + H(2)O + ROH.,function:Probably involved in redox regulation of the cell. Regulates the activation of NF-kappa-B in the cytosol by a modulation of I-kappa-B-alpha phosphorylation.,miscellaneous:Irreversibly inactivated by overoxidation of Cys-124 (to Cys-SO(3)H) upon oxidative stress.,miscellaneous:The active site is the redox-active Cys-124 oxidized to Cys-SOH. Cys-SOH rapidly reacts with Cys-245-SH of the other subunit to form an intermolecular disulfide with a concomitant homodimer formation. The enzyme may be subsequently regenerated by reduction of the disulfide by thioredoxin.,similarity:Belongs to the ahpC/TSA family.,similarity:Contains 1 thioredoxin domain.,subunit:Homodimer or heterodimer with PRDX1; disulfide-linked, upon oxidation.,
