FIG. 5.
BRV p15 is a nonstructural viral protein. The relative gel mobilities of the radiolabeled in vitro translation products of BRV S4, S4 ORF1 (15), and S4 ORF2 (16) were resolved by Tricine-SDS-16.5% PAGE and compared to the viral bands present in concentrated [3H]leucine-labeled BRV particles. The positions of the λ-, μ-, and σ-class reovirus proteins and of the p15 and p16 proteins encoded by the BRV S4 genome segment are shown on the left. The migration of molecular mass markers is indicated on the right.
