Summaries for MSRB3 Gene

Entrez Gene Summary for MSRB3 Gene

  • The protein encoded by this gene catalyzes the reduction of methionine sulfoxide to methionine. This enzyme acts as a monomer and requires zinc as a cofactor. Several transcript variants encoding two different isoforms have been found for this gene. One of the isoforms localizes to mitochondria while the other localizes to endoplasmic reticula. [provided by RefSeq, Jul 2010]

GeneCards Summary for MSRB3 Gene

MSRB3 (Methionine Sulfoxide Reductase B3) is a Protein Coding gene. Diseases associated with MSRB3 include Deafness, Autosomal Recessive 74 and Autosomal Recessive Non-Syndromic Sensorineural Deafness Type Dfnb. Among its related pathways are Protein repair and Metabolism of proteins. Gene Ontology (GO) annotations related to this gene include peptide-methionine (R)-S-oxide reductase activity. An important paralog of this gene is MSRB2.

UniProtKB/Swiss-Prot for MSRB3 Gene

  • Catalyzes the reduction of free and protein-bound methionine sulfoxide to methionine. Isoform 2 is essential for hearing.

  • Deafness, autosomal recessive, 74 (DFNB74) [MIM:613718]: A form of non-syndromic sensorineural deafness characterized by prelingual, bilateral, profound hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. {ECO:0000269 PubMed:21185009}. Note=The disease is caused by mutations affecting the gene represented in this entry. A nonsense mutation affecting exclusively mitochondrial isoform 2 is sufficient to produce hearing loss.
