Peroxiredoxin-6 is a protein that in humans is encoded by the PRDX6 gene.[1][2]


The protein encoded by this gene is a member of the thiol-specific antioxidant protein family. This protein is a bifunctional enzyme with two distinct active sites. It is involved in redox regulation of the cell; it can reduce H(2)O(2) and short chain organic, fatty acid, and phospholipid hydroperoxides. It may play a role in the regulation of phospholipid turnover as well as in protection against oxidative injury.[2]

Model organisms[edit]

Model organisms have been used in the study of PRDX6 function. A conditional knockout mouse line, called Prdx6tm1a(EUCOMM)Wtsi[7][8] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[9][10][11]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[5][12] Twenty five tests were carried out on mutant mice but no significant abnormalities were observed.[5]
