    Summary
    Predicted to be involved in mitochondrial respirasome assembly and regulation of oxidative phosphorylation. Located in mitochondrial inner membrane. Part of respiratory chain complex IV. Is expressed in adult head and adult heart. Used to study cytochrome-c oxidase deficiency disease and epilepsy. Orthologous to several human genes including COX7A1 (cytochrome c oxidase subunit 7A1).
