title: The functional domains of the phosphoprotein (NS) of vesicular stomatitis virus (Indiana serotype).
abstract: A full-length cDNA clone of the mRNA encoding the phosphoprotein (NS) of the Indiana serotype of vesicular stomatitis virus was inserted into the SP6 transcription vector. By in vitro transcription of the inserted gene followed by translation of the mRNA in a rabbit reticulocyte lysate, NS protein was synthesized. The biological activity of the protein was demonstrated by RNA synthesis in vitro by reconstitution with L protein and N-RNA template purified from virions. Using oligonucleotide-directed RNase H cleavage of the full-length NS mRNA, a series of deleted RNAs were made which gave rise to corresponding size classes of truncated NS protein after translation in vitro. The N-RNA template binding site was located at the C-terminal domain (21 amino acids) of the NS protein and the L-protein binding site was present within 14 amino acids spanning the NH2-terminal side of the N-RNA binding site. These results are similar to that obtained with the NS protein of the New Jersey serotype of VSV, indicating conservation of the functional domains within the VSV serotypes.
