Specificity of Rous sarcoma virus nucleocapsid protein in genomic RNA packaging.


Site-directed mutagenesis has shown that the nucleocapsid (NC) protein of Rous sarcoma virus (RSV) is required for packaging and dimerization of viral RNA. However, it has not been possible to demonstrate, in vivo or in vitro, specific binding of viral RNA sequences by NC. To determine whether specific packaging of viral RNA is mediated by NC in vivo, we… (More)
