    Summary
    Predicted to be involved in mitochondrial electron transport, cytochrome c to oxygen. Located in mitochondrial crista. Part of respiratory chain complex IV. Is expressed in several structures, including adult head; adult heart; anterior endoderm; embryonic/larval midgut primordium; and mesoderm. Used to study cytochrome-c oxidase deficiency disease. Orthologous to human COX4I2 (cytochrome c oxidase subunit 4I2). [provided by Alliance of Genome Resources, Dec 2024]
