Abstract

The human immunodeficiency virus type-1 (HIV-1) integrase protein (IN) mediates the insertion of linear double-stranded viral DNA into the host genome. Mutations in IN can have different effects on the virus life cycle. In this study, Gag-Pol polyprotein processing, Tat synthesis, and viral replication were investigated in integrase-defective HIV-1 mutants. In the absence of IN synthesis, the Gag-Pol polyprotein stability, packaging, and/or processing was reduced. There was limited expression of Tat observed in IN mutants, but no viral replication.
