Function Cytochrome c oxidase (COX, complex IV) is the terminal component of the mitochondrial respiratory chain that catalyzes the reduction of oxygen to water. Required for complex IV maintenance. {ECO:0000269PubMed:22902835}.
Subcellular Localization Mitochondrion inner membrane {ECO:0000269PubMed:23746447}; Peripheral membrane protein {ECO:0000269PubMed:23746447}; Matrix side {ECO:0000269PubMed:23746447}.
Disease Associations Leigh syndrome (LS) [MIM:256000]: An early-onset progressive neurodegenerative disorder characterized by the presence of focal, bilateral lesions in one or more areas of the central nervous system including the brainstem, thalamus, basal ganglia, cerebellum and spinal cord. Clinical features depend on which areas of the central nervous system are involved and include subacute onset of psychomotor retardation, hypotonia, ataxia, weakness, vision loss, eye movement abnormalities, seizures, and dysphagia. {ECO:0000269PubMed:23746447}. Note=The disease is caused by mutations affecting the gene represented in this entry.
