The long non-coding RNA Cerox1 is a post transcriptional regulator of mitochondrial complex I catalytic activity.

To generate energy efficiently, the cell is uniquely challenged to co-ordinate the abundance of electron transport chain protein subunits expressed from both nuclear and mitochondrial genomes. How an effective stoichiometry of this many constituent subunits is co-ordinated post-transcriptionally remains poorly understood. Here we show that Cerox1Cerox1Cerox1Cerox1
