    • A previous study using RNA interference to reduce mitofusin levels in rat cells concluded that mitofusins function in cis (on a single mitochondrial membrane) (18). These authors found that fusion of wild-type and mitofusin knockdown cells resulted in significant fusion of mitochondria. However, it is clear that the RNA interference in that study failed to completely deplete both mitofusins, because residual mitochondrial fusion was observed even in cell hybrids between double mitofusin knockdown cells [figure 5 of (18)]. In our study, the use of genetically defined, Mfn-null cells leads to definitive results. Yeast mitochondrial fusion also requires Fzo1 on adjacent membranes, on the basis of an in vitro mitochondrial fusion assay (19).
