DNase footprinting analysis of the Sp1-hsp70 TATA promoter. The T-antigen (Tag)-mediated stimulation of the formation of the TA complex, shown in Fig. 2, was verified in similar binding studies analyzed by DNase footprinting. Increasing concentrations of TBP (0.5, 5, and 50 ng) were used in reactions with TFIIA, TFIIB, and T antigen (as indicated; also described in Materials and Methods).
