  • Title: Glycoprotein gene relocation in rabies virus.
    Author: Wu X, Rupprecht CE.
    Journal: Virus Res; 2008 Jan; 131(1):95-9. PubMed ID: 17850911.
    Abstract:
    Unlike vesicular stomatitis virus, rabies virus glycoprotein gene has not been successfully relocated closer to promoter-proximal regions by reverse genetics. Here we describe an efficient system for the Evelyn-Rokitnicki-Abelseth (ERA) rabies virus with the glycoprotein gene switched with the matrix protein gene, creating a reshuffled virus ERAgm (gene order N-P-G-M-L). With the aid of an autogene plasmid, the T7 RNA polymerase containing a nuclear location signal from the SV40 large T antigen facilitated virus recovery. The rearranged ERAgm rabies virus replicated as well as the parental ERA (gene order N-P-M-G-L) virus, reaching 10(9) ffu/ml in infected BSR cells. The altered glycoprotein gene position in viral genome presented an alternative way to study the pathogenicity of rabies virus. This also provides a potential novel method for rabies vaccine development.
