Re: what is the role of the protein peroxiredoxin and what are the functions

Peroxiredoxin is a cytoplasmic homodimeric protein involved in redox regulation of the cell. It reduces peroxides by reducing equivalents provided through the thioredoxin system but not from glutaredoxin. It may play an important role in eliminating peroxides generated during metabolism, and might participate in the signaling cascades of growth factors and tumor necrosis factor-alpha by regulating the intracellular concentrations of H(2)O(2)(peroxide).
