A TATA complex that forms on the hsp70 promoter has been found to depend on sequence-specific interactions that occur at the transcription start and regions further downstream. The complex was detected with a gel shift assay and further characterized with interference assays. Antibodies reveal that the TATA-binding protein is in the complex. Interference assays localize specific contacts in the TATA element, the start site, and in a region approximately 25 bp downstream of the start site that contribute to either the assembly or the maintenance of the complex. Contact at the TATA element is made in the minor groove, as has been reported for the recombinant TATA-binding protein. Mutation in the TATA element or the start site of hsp70 causes complex formation to be more strongly dependent on contacts in the +25 region than in the normal core promoter. Examination of the hsp26 and histone H4 genes indicates that similar contacts contribute to the TATA complexes that form on these promoters. The results suggest that specific contacts downstream of the TATA element could play a key role in establishing the transcriptional potential of a gene by contributing to the interaction of the TATA-binding protein.
