Predicted to be involved in several processes, including mitochondrial cytochrome c oxidase assembly; positive regulation of cytochrome-c oxidase activity; and protein stabilization. Predicted to act upstream of or within intrinsic apoptotic signaling pathway. Predicted to be located in matrix side of mitochondrial inner membrane. Predicted to be active in mitochondrion. Human ortholog(s) of this gene implicated in cytochrome-c oxidase deficiency disease. Orthologous to human COA8 (cytochrome c oxidase assembly factor 8).
