Activity summary

Peroxiredoxin 4 also known as Prdx4 is a protein that acts as an antioxidant enzyme and belongs to the peroxiredoxin family. It influences the reduction of hydrogen peroxide and organic hydroperoxides. The molecular mass of Prdx4 is approximately 31 kDa. It is expressed mainly in the endoplasmic reticulum but you can find some expression in the cytosol as well.

Biological function summary

Prdx4 plays a list of roles in cellular defense against oxidative stress. It not only reduces peroxides but also contributes to the maintenance of protein folding by modifying disulfide bonds in the endoplasmic reticulum. Prdx4 does not function as part of a larger complex but acts independently within its compartments. The protective functions of Prdx4 are important for cell survival and proper cellular function.

Pathways

Prdx4 interacts with oxidative stress response pathways. Specifically it participates in the redox signaling pathways that regulate cellular reactive oxygen species levels. Peroxiredoxin 4 is closely associated with proteins such as thioredoxin in these pathways. Together they regulate the cellular redox environment which is important for maintaining cellular homeostasis.

Associated diseases and disorders

Oxidative stress imbalance implicates Prdx4 in conditions like diabetes and cancer. For example in diabetes altered Prdx4 levels disturb normal cell function due to increased oxidative stress. In cancer Prdx4 can influence tumor progression by modulating the antioxidant capacity within cells. Prdx4 also shows a functional connection to proteins like glutathione peroxidase in regulating oxidative stress-related pathologies.
