VSIV enters the cell through partially clathrin-coated vesicles; virus-containing vesicles contain more clathrin and clathrin adaptor than conventional vesicles. Virus-containing vesicles recruit components of the actin machinery for their interaction, thus inducing its own uptake. VSIV G does not follow the same path as most vesicles because transport of the G protein from the ER to the plasma membrane is interrupted by incubation at 15 °C. Under this condition, the molecules accumulate in both the ER and a subcellular vesicle fraction of low density called the lipid-rich vesicle fraction. The material in the lipid-rich vesicle fraction appears to be a post-ER intermediate in the transport process to the plasma membrane (PM). After infection, the VSIV G gene is expressed and is commonly studied as a model for N-linked glycosylation in the endoplasmic reticulum (ER). It is translated into the rough ER where the Glc3-Man9-GlcNac2 oligosaccharide is added by a dolichol-containing protein, to an NXS motif on VSIV G. Sugars are removed gradually as the protein travels to the Golgi apparatus, and it becomes resistant to endoglycosidase H. When synthesized in polarized epithelial cells, the envelope glycoprotein VSV G is targeted to the basolateral PM. VSVG is also a common coat protein for lentiviral vector expression systems used to introduce genetic material into in vitro systems or animal models, mainly because of its extremely broad tropism. The VSIV L protein is encoded by half the genome, and combines with the phosphoprotein to catalyze replication of the mRNA.
