MSRA is His-tagged at the N-terminal. MSRA (Methionine sulfoxide reductase, EC1.8.4.6) is ubiquitous and highly conserved. It carries out the enzymatic reduction of methionine-S-sulfoxide (MetSO) to methionine in thioredoxin-dependent manner. Human and animal studies have shown the highest levels of expression in kidney and nervous tissue. Its proposed function is the repair of oxidative damage to proteins to restore biological activity. The two known splice variants of the mammalian protein are located in mitochondria and the cytosol, respectively.
