Lupashin VV, et al. (1996) Biochemical requirements for the targeting and fusion of ER-derived transport vesicles with purified yeast Golgi membranes. J Cell Biol 132(3):277-89
Abstract: In order for secretion to progress, ER-derived transport vesicles must target to, and fuse with the cis-Golgi compartment. These processes have been reconstituted using highly enriched membrane fractions and partially purified soluble components. The functionally active yeast Golgi membranes that have been purified are highly enriched in the cis-Golgi marker enzymes alpha 1,6 mannosyltransferase and GDPase. Fusion of transport vesicles with these membranes requires both GTP and ATP hydrolysis, and depends on cytosolic and peripheral membrane proteins. At least two protein fractions from yeast cytosol are required for the reconstitution of ER-derived vesicle fusion. Soluble fractions prepared from temperature-sensitive mutants revealed requirements for the Ypt1p, Sec19p, Sly1p, Sec7p, and Uso1 proteins. A model for the sequential involvement of these components in the targeting and fusion reaction is proposed.
