Predicted to enable peptide-methionine (R)-S-oxide reductase activity and zinc ion binding activity. Predicted to be involved in protein repair. Predicted to be located in endoplasmic reticulum and mitochondrion. Predicted to be active in cytoplasm. Is expressed in several structures, including heart; inner ear; jaw; limb; and skeleton. Used to study autosomal recessive nonsyndromic deafness 74. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 74. Orthologous to human MSRB3 (methionine sulfoxide reductase B3). [provided by Alliance of Genome Resources, Apr 2022]
