Function
Thioredoxin (Trx) is an enzyme which facilitates, in its reduced form, the reduction of proteins by cysteine thiol-disulfide exchange[1]. They contain a CXXC motif.
- Trx-1 is a mammalian cellular protein.
- Trx-2 is mitochondria-specific.
In higher plants, Trx are divided to 6 groups based on their sequence. Trx M, X and Y are found in prokaryotes while F, H and O are found in eukaryotes.
Relevance
Serum Trx level is a predictor of steatohepatitis[2].
Disease
Trx is involved in a wide range of human diseases and conditions including cancer, viral diseases, aging, cardiac conditions and more[3].
