PRDX6 (peroxiredoxin 6) is a mammalian peroxidase belonging to the 1-Cys Prdx family, meaning it has 1-Cys at position 47 (Cys47). This protein is localized to cytoplasm, lysosomes, mitochondria, endoplasmic reticulum (ER) and plasma membrane. It is a homodimeric protein which is especially observed in mammalian lungs.†

生物化学的/生理学的作用
PRDX6 (peroxiredoxin 6) has both peroxidase and phospholipase A2 (PLA2) activities and thus, is a bifunctional protein. In liver, as a peroxidase it confers protection against damage from ROS (reactive oxygen species) during ischemia-reperfusion injury. As a PLA2 it is involved in lung surfactant metabolism. It is also essential for normal nicotinamide adenine dinucleotide phosphate-oxidase activity. In the livers of donors after brain death (DBD), this protein suppresses ischemia- and hypoxia-induced liver damage, and its expression is controlled by NF-κB (nuclear factor). In human and mouse neuronal cells, the delivery of PRDX6 protein leads to delay or suppression in oxidative stress-induced neuronal cell death.
Peroxiredoxin 6 contains a single redox-active cysteine and uses glutathione to catalyze the reduction of H2O2 and other organic peroxides. Overexpression of peroxiredoxin 6 in cells protects them against oxidative damage, whereas knockdown of this enzyme results in oxidative stress and apoptosis. The phospholipase A2 activity plays an important role in surfactant homeostasis. Peroxiredoxin 6 is a major antioxidant enzyme which functions in antioxidant defense and lung phospholipid metabolism.

Reactive oxygen species (ROS) play an important role in the development of various pathological conditions as well as aging. ROS oxidize DNA, proteins, lipids, and small molecules. Carbonylation is one mode of protein oxidation that occurs in response to the
