Peptide methionine sulfoxide reductase is an enzyme that in humans is encoded by the MSRA gene.[1][2]
Function
This protein is ubiquitous and highly conserved. It carries out the enzymatic reduction of methionine sulfoxide to methionine. Human and animal studies have shown the highest levels of expression in kidney and liver. Its proposed function is the repair of oxidative damage to proteins to restore biological activity.[2]
Clinical significance
Deletion of this gene has been associated with insulin resistance in mice.[3]
