  2. Natural killer cell-enhancing factor B
  3. PRP

  5. Thiol-specific antioxidant protein
  6. Thioredoxin peroxidase 1
  7. Thioredoxin-dependent peroxide reductase 1
Gene Name PRDX2
Protein Type Unknown
Biological Properties
General Function Involved in antioxidant activity
Specific Function Involved in redox regulation of the cell. Reduces peroxides with reducing equivalents provided through the thioredoxin system. It is not able to receive electrons from glutaredoxin. May play an important role in eliminating peroxides generated during metabolism. Might participate in the signaling cascades of growth factors and tumor necrosis factor-alpha by regulating the intracellular concentrations of H(2)O(2).
