Abstract
To identify RNA and protein sequences involved in packaging of human immunodeficiency virus type 1 (HIV-1), various mutations were introduced into the viral genome. Portions of the human immunodeficiency virus type 1 genome between the first splice donor site and the gag initiation codon were deleted to investigate the RNA packaging site (psi). Point mutations that alter cysteine residues in one or both zinc finger motifs of p7, a cleavage product of the gag precursor, were created to study the role of the gag zinc fingers in packaging. The psi site mutants and the gag mutants exhibited similar phenotypes. Cells transfected with the mutant genomes, while expressing normal levels of human immunodeficiency virus type 1 RNA and proteins, produced viral particles that were normal in protein content but lacked detectable viral RNA. These mutant virions were unable to productively infect cells. The combination of human immunodeficiency virus type 1 packaging mutations should minimize fortuitous assembly of infectious virus and may provide a means to produce noninfectious particles for candidate vaccines.
