FIG. 5.

Correlation of transcriptional activation by T antigen and the stimulation of the formation of the TA complex on the four TATA elements. (A) T-antigen (T Ag)-mediated transcriptional activation of the promoters shown in Fig. 1 containing the hsp70, fos, SV40 early, and Ad E2A TATA elements. (B) T-antigen-mediated stimulation of the formation of the TA complex on the TATA elements of the four promoters shown in Fig. 1.
