Although the enzymes responsible for farnesyl and palmitoyl lipid addition have been described, the mechanism by which these modifications contribute to the subcellular localization of Ras is not known. Following addition of the farnesyl group, Ras associates with the endoplasmic reticulum (ER), where palmitoylation occurs in Saccharomyces cerevisiae. The subsequent translocation of Ras from the ER to the plasma membrane does not require the classical secretory pathway or a functional Golgi apparatus. Vesicular and nonvesicular transport pathways for Ras proteins have been proposed, but the pathway is not known. Here we describe a genetic screen designed to identify mutants defective in Ras trafficking in S. cerevisiae. The screen implicates, for the first time, the class C VPS complex in Ras trafficking. Vps proteins are best characterized for their role in endosome and vacuole membrane fusion. However, the role of the class C Vps complex in Ras trafficking is distinct from its role in endosome and vacuole vesicle fusion, as a mitochondrial involvement was uncovered. Disruption of class C VPS genes results in mitochondrial defects and an accumulation of Ras proteins on mitochondrial membranes. Ras also fractionates with mitochondria in wild-type cells, where it is detected on the outer mitochondrial membrane by virtue of its sensitivity to protease treatment. These results point to a previously uncharacterized role of mitochondria in the subcellular trafficking of Ras proteins."xsd:string |
