Peroxiredoxin-6 is a protein that in humans is encoded by the PRDX6 gene.^[5]^[6] It is a member of the peroxiredoxin family of antioxidant enzymes.

Function

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.^[6]
