Target Information

The mammalian thioredoxin reductases (TrxRs) are a family of selenocysteine-containing pyridine nucleotide-disulfide oxidoreductases. All mammalian TrxRs are homologous to glutathione reductase with respect to primary structure, including the conserved redox catalytic site (-Cys-Val-Asn-Val-Gly-Cys-), but distinctively possess a C-terminal extension containing a catalytically active penultimate selenocysteine (SeCys) residue in the conserved sequence (-Gly-Cys-SeCys-Gly-).

TrxR is a homodimeric protein in which each monomer includes an FAD prosthetic group, a NADPH binding site, and a redox catalytic site. Electrons are transferred from NADPH via FAD and the active-site disulfide to the C-terminal SeCys-containing redox center, which then reduces substrates such as thioredoxin.

Members of the TrxR family are 55–58 kDa in molecular size and include three isoforms:

• Cytosolic TrxR1
• Mitochondrial TrxR2
• TrxR3 (also known as Trx and GSSG reductase, TGR)

TrxR plays a key role in protecting cells against oxidative stress and regulating transcription factors and various biological processes.
