Supplementary information

COX8A also known as Cytochrome c oxidase subunit 8A is a component of the cytochrome c oxidase complex which plays a vital role in the electron transport chain within mitochondria. This protein has a molecular mass of approximately 8.7 kDa. COX8A is highly expressed in tissues with high energy demands such as muscle and brain where efficient ATP production is needed.
Biological function summary

COX8A is an integral part of the large cytochrome c oxidase complex also known as Complex IV in the mitochondrial inner membrane. This complex is involved in oxidative phosphorylation where it catalyzes the reduction of oxygen to water a final step of the electron transport chain. COX8A contributes to the correct assembly and stability of the cytochrome c oxidase complex ensuring proper mitochondrial function and energy production.

Pathways

COX8A participates in the oxidative phosphorylation pathway and is an important player in the process that produces ATP from ADP and inorganic phosphate. It functions together with other subunits in Complex IV such as COX2 and COX3 to facilitate efficient electron transfer and proton pumping. Through its activity in these processes COX8A directly influences cellular respiration and energy metabolism which are critical for cellular homeostasis.

COX8A has connections to mitochondrial disorders such as Leigh syndrome and cytochrome c oxidase deficiency. These conditions arise from defects in mitochondrial oxidative phosphorylation affecting tissues with high metabolic demands. Alterations in COX8A along with other complex IV components like COX2 can contribute to the pathogenesis of these diseases as they disrupt ATP production and lead to energy deficits in affected cells.

Target data

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.
