mt-Co3 Gene Summary [Mouse]
Predicted to contribute to cytochrome-c oxidase activity. Predicted to be involved in mitochondrial electron transport, cytochrome c to oxygen and respiratory chain complex IV assembly. Located in mitochondrion. Part of respiratory chain complex IV. Is active in mitochondrial inner membrane. Is expressed in several structures, including alimentary system; brain; heart; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in MELAS syndrome. Orthologous to human MT-CO3 (mitochondrially encoded cytochrome c oxidase III). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Mt-Co3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
