  • 功能：
    Component of the cytochrome c oxidase, the last enzyme in the mitochondrial electron transport chain which drives oxidative phosphorylation. The respiratory chain contains 3 multisubunit complexes succinate dehydrogenase (complex II, CII), ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII) and cytochrome c oxidase (complex IV, CIV), that cooperate to transfer electrons derived from NADH and succinate to molecular oxygen, creating an electrochemical gradient over the inner membrane that drives transmembrane transport and the ATP synthase. Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Electrons originating from reduced cytochrome c in the intermembrane space (IMS) are transferred via the dinuclear copper A center (CU(A)) of subunit 2 and heme A of subunit 1 to the active site in subunit 1, a binuclear center (BNC) formed by heme A3 and copper B (CU(B)). The BNC reduces molecular oxygen to 2 water molecules using 4 electrons from cytochrome c in the IMS and 4 protons from the mitochondrial matrix.

    1. Study shows that higher COX-2 and ALOX5 expression in colorectal cancer (CRC) tissues was correlated with poorer prognosis in patients with CRC. Also, MiR-216a-3p was shown to directly bind to there 3'-UTR and inversely regulates their protein levels modulating CRC cell proliferation. PMID: 28786533
    2. Data suggest that mutations in MT-CO2 and MT-ND5 can be involved in MIDD (maternally inherited diabetes and deafness); a Tunisian family (mother, daughter, son) with clinical features of MIDD associated with retinopathy exhibit mutations in MT-CO2 (m.8241T>G - p. F219C) and MT-ND5 (m.13276G>A - p. M314V); these two mutations could explain retinopathy in some family members. (MT-ND5 = NADH dehydrogenase subunit 5) PMID: 27422531

The sequencing analysis revealed the presence of 17 variants, mostly causing non-synonymous changes in conserved amino acid residues, typically distributed in the MT-CO2 gene of MUTYH-associated polyposis patients (P < 0.0001), who frequently carried the hot spot m.7763G>A variant. PMID: 26138249
    7. Results find that COA6 associates with COX2 and is crucial for its maturation and complex IV biogenesis. Also, COA6 interacts with the copper chaperone SCO1 which indicates that COA6 is intrinsically involved in the copper delivery process for COX2. PMID: 26160915
