gene geneOn this page
Summary
COA6 (cytochrome c oxidase assembly factor 6, HGNC:18025) is a protein-coding gene on chromosome 1q42.2, encoding Cytochrome c oxidase assembly factor 6 homolog (Q5JTJ3). Involved in the maturation of the mitochondrial respiratory chain complex IV subunit MT-CO2/COX2. It is a selective cancer dependency (DepMap: 28.1% of cell lines).
This gene encodes a member of the cytochrome c oxidase subunit 6B family. The encoded protein associates with cytochrome c oxidase may act has an cytochrome c oxidase mitochondrial respiratory complex VI assembly factor. Mutations in this gene may be associated with fatal infantile cardiomyopathy. Alternate splicing results in multiple transcript variants.

- Cooperation between COA6 and SCO2 in COX2 maturation during cytochrome c oxidase assembly links two mitochondrial cardiomyopathies. (PMID:25959673)
- 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)
- Data present the crystal structures of human Coa6 and the pathogenic (W59C)Coa6-mutant protein. These structures show that Coa6 has a 3-helical bundle structure, with the first 2 helices tethered by disulfide bonds, one of which likely provides the copper-binding site. Disulfide-mediated oligomerization of the (W59C)Coa6 protein provides a structural explanation for the loss-of-function mutation. (PMID:31515291)

Cytochrome c oxidase assembly factor 6 homolog — Q5JTJ3 (reviewed: Q5JTJ3)
All UniProt accessions (1): Q5JTJ3
UniProt curated annotations — full annotation on UniProt →
Function. Involved in the maturation of the mitochondrial respiratory chain complex IV subunit MT-CO2/COX2. Thereby, may regulate early steps of complex IV assembly. Mitochondrial respiratory chain complex IV or cytochrome c oxidase is the component of the respiratory chain that catalyzes the transfer of electrons from intermembrane space cytochrome c to molecular oxygen in the matrix and as a consequence contributes to the proton gradient involved in mitochondrial ATP synthesis. May also be required for efficient formation of respiratory supercomplexes comprised of complexes III and IV.
Subunit / interactions. Interacts with COA1. Found in a complex with TMEM177, COX20, MT-CO2/COX2, COX18, SCO1 and SCO2. Interacts with MT-CO2/COX2 and SCO2. Interacts with SCO1. Interacts with COX20 in a MT-CO2/COX2- and COX18-dependent manner. Interacts with COX16.
Subcellular location. Mitochondrion intermembrane space.
Disease relevance. Mitochondrial complex IV deficiency, nuclear type 13 (MC4DN13) [MIM:616501] An autosomal recessive, infantile disorder with a fatal course in the first weeks of life, characterized by hypertrophic cardiomyopathy, left ventricular non-compaction, lactic acidosis, metabolic hypotonia, and mitochondrial complex IV deficiency. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the cytochrome c oxidase subunit 6B family.
