    ..Genetical analysis revealed that the Mmr1p-Myo2p pathway is independent of the Ypt11p-Myo2p pathway, suggesting that an essential system for mitochondrial distribution is composed of two independent Myo2p pathways. ..

    ..Finally, we show that ERMES complexes are long-lived, and do not depend on the presence of Gem1. Our findings suggest that the ERMES complex may have primarily a structural role in maintaining mitochondrial morphology. ..
