Summary: Cytochrome c oxidase (COX) catalyzes the transfer of electrons from cytochrome c to molecular oxygen, which helps to maintain the proton gradient across the inner mitochondrial membrane that is necessary for aerobic ATP production. Human COX is a multimeric protein complex that requires several assembly factors; this gene encodes one of the COX assembly factors. The encoded protein is a metallochaperone that is involved in the biogenesis of cytochrome c oxidase subunit II. Mutations in this gene are associated with fatal infantile encephalocardiomyopathy and myopia 6. [provided by RefSeq, Oct 2014]

oxidative stress-induced glycolysis-to-OXPHOS switch is mediated by synthesis of cytochrome c oxidase 2 (SCO2). These findings demonstrate p53-mediated OXPHOS function as a compensatory alteration in Fanconi anemia (FA)hematopoietic stem cells to ensure a functional but mildly impaired energy metabolism and suggest a cautious approach to manipulating p53 signaling in FA.

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.
