Mitochondrially encoded cytochrome c oxidase III (MT-CO3; COX3) is encoded by the mitochondrial DNA and localizes to the inner mitochondrial membrane. COX3 is generally mentioned as COXIII.
Immunogen
Synthetic peptide directed towards the C terminal region of human COX3
Application
Anti-COX3 antibody produced in rabbit is suitable for western blotting at a concentration of 1.0μg/ml.
Biochem/physiol Actions
Cytochrome oxidases make up the terminal complex of the electron transport chain in the mitochondria. Deletions in mitochondrially encoded cytochrome c oxidase III (MT-CO3; COX3) gene are associated with rhabdomyolysis. Mutation in COX3 is linked to maternally inherited diabetes and deafness associated with nephropathy. COX3 mutations have been observed in asthenozoospermic infertile men, patients with MELAS (mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes) and Leber hereditary optic neuropathy. Hepatitis B virus X protein interacts with COX3 and the intercation might be crucial for hepatocarcinoma tumorigenesis.

Mitochondrial diabetes (MD) is a heterogeneous disorder characterized by a chronic hyperglycemia, maternal transmission and its association with a bilateral hearing impairment. Several studies reported mutations in mitochondrial genes as potentially pathogenic for diabetes, since mitochondrial oxidative phosphorylation plays an
We report a patient with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) who harbored a novel missense mutation at mtDNA position 9957 in the gene specifying subunit III of cytochrome c oxidase (COX III). This T-->C transition converted Phe-251

The hepatitis B virus (HBV) X protein (HBx) plays an important pathogenetic role in hepatocarcinoma tumorigenesis. As HBx does not have the ability to bind to double-stranded DNA (dsDNA), protein-protein interaction is crucial for HBx functions. In a previous study
