The complete sequence of genome segment 8 of bluetongue virus, serotype 1, which encodes the nonstructural protein, NS2.
Bluetongue virus has a ten-segment double-stranded RNA genome, of which segment 8 encodes a nonstructural protein NS2. This protein is the only bluetongue viral protein to be phosphorylated and also has the ability to bind single-stranded RNA. At present, the function of NS2 is unknown and in order to analyse its characteristics in more detail, it was first necessary to obtain a full-length cDNA clone of the genome segment.
