RESUMO

We investigated whether the T antigen of the simian virus 40-transformed human cell line simian virus 80 ( SV80 ) specifically recognizes DNA sequences of its own template, i.e, the viral sequences integrated in the SV80 cellular genome. In vitro DNA binding experiments clearly indicated that, in contrast to wild-type T antigen, SV80 T antigen does not specifically bind to sites on the integrated viral DNA in SV80 cells.
