The impact of mutations affecting highly conserved amino acids in the simian immunodeficiency virus nucleocapsid protein on virion assembly, genomic RNA packaging and viral infectivity.

Abstract excerpt

The nucleocapsid (NC) domain of the retroviral Gag polyproteins mediates the incorporation of the viral genomic RNA into virions. Although SIV is widely used as a model for human immunodeficiency virus type 1 (HIV-1) infections, the SIV NC has been the subject of few studies which have provided discrepant data on the relative contribution of the two NC zinc finger motifs to genomic RNA encapsidation. Here, we...
