Summary	This nuclear gene encodes a mitochondrial member of the thioredoxin family, a group of small multifunctional redox-active proteins. The encoded protein may play important roles in the regulation of the mitochondrial membrane potential and in protection against oxidant-induced apoptosis. [provided by RefSeq, Jul 2008]
Protein Families	Protocol: Activity Assay 1. Prepare a 1 ml reaction cocktail into a suitable container : The final concentrations are 5mM Tris, 63mM sodium phosphate, 1mM DTT, 0.1% (w/v) insulin, 2mM EDTA. 2. Add 4 ug of recombinant thioredoxin2 into reaction cocktail and mix immediately. 3. Incubate at 25°C for 20 minutes. 4. Record the increase in A650nm for 15 minutes.
