Abstract

Cells transformed with bovine papilloma virus type 1 mutants in the E6 or E6/7 genes are resistant to high-copy-number amplification of wild-type DNA after supertransfection. Transient and stable replication assays demonstrate this effect. If the supertransfected DNA has a mutation in a newly defined gene (M), this cellular immunity to high-copy-number replication is overcome, resulting in transient replication of the input DNA. In contrast, the resident plasmid does not participate in amplification and is maintained at a constant low copy number. Cotransformation of M- mutants and wild-type DNA into these cells leads to shutoff of replication of both genomes. Thus, M- mutants define a trans-acting negative modulator that regulates viral replication. This function is distinct from the positive factors required for replication. We propose a model that explains why the loss of E6 and E6/7 function leads to immunity of the infected cell.
