RESUMO

We developed an in vitro binding assay to study the specific interaction between human immunodeficiency virus type 1 (HIV-1) RNA and the Gag polyprotein. Binding of the in vitro-expressed protein to in vitro-transcribed RNA was determined by altered migration of the protein in polyacrylamide gels. We found that a Gag precursor lacking the matrix domain bound specifically to HIV-1 RNA, while deletion of both matrix and capsid domains diminished the specificity of binding. Among several regions of HIV-1 RNA tested, strongest binding was seen with the 5'-most 261 nucleotides, while antisense RNA from the same region did not bind.
