Twin [CX.sub.9]C proteins were found to be conserved across the organisms included in the study, except for three obligate intercellular parasites that contain mitosomes. The evolutionary conservation across organisms containing true mitochondria suggested that these [CX.sub.9]C proteins are important in mitochondrial function and, indeed, members of this family operate as subunits in complexes I and IV of the electron transport chain (ETC), as cytochrome c oxidase (COX) assembly factors, and they participate in mitochondrial protein import, structure, and function.
