The surface of the bluetongue virus core forms a T=13 quasiequivalent icosahedral protein shell with 260 trimers of a single gene product: VP7 protein. Underneath is a smooth layer, made up of VP3 protein, which appears to guide and nucleate the assembly of VP7 trimers. The contacts between the two shells are extensive but nonspecific, and construction of the T=13 icosahedral shell requires polymorphism in the association of the VP7 subunits, each of which has two domains that contribute to… CONTINUE READING
