Summary
COX8A (cytochrome c oxidase subunit 8A, HGNC:2294) is a protein-coding gene on chromosome 11q13.1, encoding Cytochrome c oxidase subunit 8A, mitochondrial (P10176). Component of the cytochrome c oxidase, the last enzyme in the mitochondrial electron transport chain which drives oxidative phosphorylation.
The protein encoded by this gene is the terminal enzyme of the respiratory chain, coupling the transfer of electrons from cytochrome c to molecular oxygen, with the concomitant production of a proton electrochemical gradient across the inner mitochondrial membrane. In addition to 3 mitochondrially encoded subunits, which perform the catalytic function, the eukaryotic enzyme contains nuclear-encoded smaller subunits, ranging in number from 4 in some organisms to 10 in mammals. It has been proposed that nuclear-encoded subunits may be involved in the modulation of the catalytic function. This gene encodes one of the nuclear-encoded subunits.

Function. 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.
Subunit / interactions. Component of the cytochrome c oxidase (complex IV, CIV), a multisubunit enzyme composed of 14 subunits. The complex is composed of a catalytic core of 3 subunits MT-CO1, MT-CO2 and MT-CO3, encoded in the mitochondrial DNA, and 11 supernumerary subunits COX4I1 (or COX4I2), COX5A, COX5B, COX6A1 (or COX6A2), COX6B1 (or COX6B2), COX6C, COX7A2 (or COX7A1), COX7B, COX7C, COX8A and COXFA4, which are encoded in the nuclear genome. The complex exists as a monomer or a dimer and forms supercomplexes (SCs) in the inner mitochondrial membrane with NADH-ubiquinone oxidoreductase (complex I, CI) and ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII), resulting in different assemblies (supercomplex SCI(1)III(2)IV(1) and megacomplex MCI(2)III(2)IV(2)).
Subcellular location. Mitochondrion inner membrane.
Tissue specificity. Widely expressed.
Post-translational modifications. In response to mitochondrial stress, the precursor protein is ubiquitinated by the SIFI complex in the cytoplasm before mitochondrial import, leading to its degradation. Within the SIFI complex, UBR4 initiates ubiquitin chain that are further elongated or branched by KCMF1.
Disease relevance. Mitochondrial complex IV deficiency, nuclear type 15 (MC4DN15) [MIM:619059] An autosomal recessive mitochondrial disorder with onset in infancy. MC4DN15 is characterized by global developmental delay, poor feeding, metabolic acidosis, short stature, microcephaly, proximal muscle weakness, and distal spasticity. Additional manifestations include scoliosis, primary pulmonary hypertension, refractory seizures, and inability to walk. Serum and CSF lactate levels are increased. Patient tissues show decreased levels and activity of mitochondrial respiratory complex IV. The disease may be caused by variants affecting the gene represented in this entry.
Pathway. Energy metabolism; oxidative phosphorylation.
Similarity. Belongs to the cytochrome c oxidase VIII family.
