    Summary
    Enables actin binding activity; peptide-methionine (R)-S-oxide reductase activity; and zinc ion binding activity. Involved in actin filament polymerization and 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).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
