  • Title: Cytoplasmic compartmentalization of the protein and ribonucleic acid species of vesicular stomatitis virus.
    Author: Wagner RR, Kiley MP, Snyder RM, Schnaitman CA.
    Journal: J Virol; 1972 Apr; 9(4):672-83. PubMed ID: 4336563.
    Abstract:
    The cytoplasmic sites of synthesis in L cells of the protein and ribonucleic acid species of vesicular stomatitis virus were studied by polyacrylamide gel electrophoresis after fractionation of membrane and other cytoplasmic components by the Caliguiri-Tamm technique. The viral spike protein (glycoprotein G) was found primarily associated with a smooth membrane fraction which is rich in plasma membrane; the G protein was also present in fractions containing rough endoplasmic reticulum. The nonglycosylated envelope protein S (also called M) was found in the smooth membrane fractions but was more abundant in endoplasmic reticulum-enriched fractions. Longer labeling resulted in detection of nucleoprotein N, as well as other minor nucleocapsid proteins L and NS(1), in the cellular membrane fractions. The N protein appeared to be made in membrane-free cytoplasm along with progeny ribonucleic acid and later became associated with membrane containing G and S viral proteins.
