Assembly of five bluetongue virus proteins expressed by recombinant baculoviruses: inclusion of the largest protein VP1 in the core and virus-like proteins.
Bluetongue virus (BTV) VP1 protein, a component of the viral RNA-directed RNA polymerase, but not the VP4 or VP6 proteins, was specifically incorporated into baculovirus expressed BTV core-like particles (composed of VP3 and VP7) and BTV virus-like particles (composed of VP2, VP3, VP5, and VP7). The VP1 protein has been shown to be associated with subcore particles composed of VP3. The data suggest that the VP1 protein of BTV has both enzymatic and structural roles in the virus life cycle.
