6M-MuLV mutants containing deldtions around the putative packaging signal were constructed by using recombinant DNA technique and transfected into NIH/3T3 cell. 2 of 6 mutants can not be packaged into virions even in the presence of the wild type helper virus. The boundary between the packagible and the non-packagible genome is located around Pvu I site, 421 nucleotide downstream from the 5' end of M-MuLV genome. 10 base pair inverted repeat sequence (GAGUCCAAAA) which can make stem structure around Pvu Isite could be the putative packaging signal.
