| Abstract: | A mutant of Moloney murine leukemia virus was generated in which the UAG termination codon at the 3' end of the gag gene was changed to a CAG codon encoding glutamine. Cells carrying the mutant provirus constitutively express the gag-pol fusion protein and no detectable gag protein. The precursor is stable, is not processed by the protease domain within the precursor, and does not induce assembly and release of virion particles. |
