Web31 aug. 2024 · Therefore, the mitochondrial-specific translation has evolved to be coordinated by mitonuclear interactions to respond to the energetic demands of the cell, acquiring unique and mosaic features. However, mitochondrial-DNA-encoded genes are essential for the assembly of the respiratory chain complexes. The mitonuclear interaction governs the integrity of OXPHOS and ensuing metabolic functions, and therefore should be under intense selection.
