The G protein of vesicular stomatitis virus is a transmembrane glycoprotein that is transported from its site of synthesis in the rough endoplasmic reticulum to the plasma membrane via the Golgi apparatus. Pulse-chase experiments suggest that G is transported to the cell surface in two successive waves of clathrin-coated vesicles. The oligosaccharides of G protein carried in the early wave are of the "high-mannose" (G1) form, whereas the oligosaccharides in the second, later wave are of the mature "complex" (G2) form. the early wave is therefore proposed to correspond to transport of G in coated vesicles from the endoplasmic reticulum to the Golgi apparatus, and the succeeding wave to transport from the Golgi apparatus to the plasma membrane. The G1- and G2-containing coated vesicles appear to be structurally distinct, as judged by their differential precipitation by anticoated vesicle serum.
