Furthermore, authors found that the cytosolic translation processes control mitochondrial translation uni-directionally––i.e. the nuclear genome coordinates mitochondrial, and cytosolic, translation to orchestrate the timely synthesis of OXPHOS complexes, representing an unappreciated regulatory layer that shapes the mitochondrial proteome. This interesting whole-cell genomic profiling approach (looking concomitantly at gDNA and mtDNA transcription) establishes a foundation for studies of global gene regulation in mitochondria.
