Using Tax mutants that fail to activate either ATF -or NF-kappaB-dependent promoters and different 5' truncation mutants of the E2F-1 promoter , we show that the Tax -dependent transcriptional control of the E2F1 gene involves , at least in part , the ATF binding site located in the E2F-1 promoter .
