WebSynchronization of mitochondrial and cytoplasmic translation rates is critical for the maintenance of cellular fitness, with cancer cells being especially vulnerable to translational uncoupling. Although alterations of cytosolic protein synthesis are common in human cancer, compensating mechanisms in mitochondrial translation remain elusive. WebJan 15, 2002 · In all cases known, imported tRNAs originate from nuclear genes encoding cytosolic, eukaryotic-type tRNAs involved in cytosolic translation . An extreme situation is found in the trypanosomatids, which have lost their entire set of mitochondrial tRNA genes and therefore must import all tRNAs necessary for organellar protein synthesis (5, 6).
