Enables actin binding activity; peptide-methionine (R)-S-oxide reductase activity; and zinc ion binding activity. Involved in actin filament polymerization. Acts upstream of or within protein repair. Located in mitochondrion. Is expressed in several structures, including brown fat; heart; inner ear; skeletal muscle; and testis. Orthologous to human MSRB2 (methionine sulfoxide reductase B2).
