Thioredoxin-2 Antibody

Thioredoxin-2 (Trx2), also known as mitochondrial Thioredoxin, belongs to the evolutionarily conserved Thioredoxin family. These proteins share the Thioredoxin fold containing the active site-CGPC motif. In their reduced form, the active site cysteine residues reduce protein disulfides. The resulting active site disulfide is subsequently reduced in a reaction catalyzed by a NADPH-dependent Thioredoxin reductase. Thioredoxin-2 contains an N-terminal 59 amino acid (aa) transit sequence that is cleaved upon translocation to mitochondria. The amino acid sequence of mature mouse Thioredoxin‑2 is identical to mature rat Thioredoxin-2 and 98% identical to human Thioredoxin-2. Thioredoxin-2 interacts with specific components of the mitochondrial respiratory chain and helps regulate the membrane potential. Thioredoxin-2 is ubiquitously but variably expressed and high expression confers resistance to oxidant‑induced apoptosis.
