title: Interactions of plus and minus strand leader RNAs of the New Jersey serotype of vesicular stomatitis virus with the cellular La protein.
abstract: The New Jersey serotype of vesicular stomatitis virus (VSV-NJ) was found to synthesize a minus strand leader RNA of 44-46 bases long and a plus strand leader RNA of 47-50 bases long in infected cells. The minus strand leader RNA of VSV-NJ was found associated with the host cell La protein in infected cells by immunoprecipitation with antisera from patients with systemic lupus erythematosus. These results differ from those reported previously (J. Wilusz , M. G. Kurilla , and J. D. Keene (1983). Proc. Natl. Acad. Sci. USA 80, 5827-5831) for the similarly sized species of minus strand leader RNA made by the Indiana serotype of VSV (VSV-IND). Despite sequence differences between the 3' ends of the plus strand leader RNAs of the two serotypes, the plus strand leader RNA of VSV-NJ was found to have a pattern of La protein accumulation similar to that reported previously for the plus strand leader RNA of VSV-IND. These results provide additional support for a role for La protein in VSV replication and help further delineate the sequence requirements for La protein binding to VSV leader RNAs.
