Mitochondrial respiratory complexes are critical components of cellular energy production that require tight regulation to ensure optimal function. Rcf1 and Rcf2 are mitochondrial proteins that can physically associate with the yeast respiratory complexes III and IV, and the higher-ordered III-IV respiratory supercomplex that also contains the ADP/ATP translocase, AAC. Rcf1 can physically associate with both complex III and IV independently, and can be chemically crosslinked to AAC, indicating a close physical proximity to a predominant regulator of energy flux within the cell. It was therefore hypothesized that Rcf1, through its physical association with complexes III and IV, and its close …
