Thioredoxin (Trx) is a redox protein of approximately 12 kDa. Its primary domain is conserved across a number of Trx family members and contains a conserved catalytic site Cys-Gly-Pro-Cys. It is ubiquitous and found in many organisms from bacteria to mammals. Trx has been shown to function in cell proliferation, redox signaling and inhibition of apoptosis.
