In mammals, fusion of the mitochondrial outer membrane is controlled by two DRPs, MFN1 and MFN2, that function in place of a single outer membrane DRP, Fzo1 in yeast. We addressed the significance of two mammalian outer membrane fusion DRPs using an in vitro mammalian mitochondrial fusion assay. We demonstrate that heterotypic MFN1/MFN2 trans complexes possess greater efficacy in fusion as compared to homotypic MFN1 or MFN2 complexes. In addition, we show that the soluble form of the pro-apoptotic Bcl2 protein, Bax, positively regulates mitochondrial fusion exclusively through homotypic MFN2 trans complexes. Together, these data demonstrate functional and regulatory distinctions between MFN1 and MFN2 and provide insight into their unique physiological roles.
