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.
  • Trx C,M,X,Y are found in prokaryotes.
  • Trx F,H,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].

Structural highlights

The is involved in the reduction of disulfide bonds in proteins[4]
