Abstract
Redox signaling is one of way to regulate growth and death of cell in response to change of redox of proteins. To search whether translation is regulated by redox, we attempted in vitro translation assay under condition with or without DTT. Interestingly in vitro translation activity was increased up to 40% In the presence of dithiothreitol (DTT). Then we checked whether this positive effect by DTT was further accelerated by addition of thioredoxin (Trx). When a Trx purified from Saccharomyces cerevisiae was added to the in vitro translation extract, we observed a dose-dependent increase in translational activity. These results suggest the possibility of translation factors being redox-regulated via Trx in vivo.
