    Summary
    Contributes to cytochrome-c oxidase activity. Involved in mitochondrial electron transport, cytochrome c to oxygen. Located in mitochondrion. Part of mitochondrial respiratory chain complex IV. Human ortholog(s) of this gene implicated in cytochrome-c oxidase deficiency disease. Orthologous to human COX4I1 (cytochrome c oxidase subunit 4I1).
