Direct interaction between the transcriptional activation domain of human p53 and the TATA box-binding protein.

The human p53 tumor suppressor gene product can activate transcription by RNA polymerase II in the yeast, Saccharomyces cerevisiae, as well as in human cells. Several viral transcriptional activator proteins have been shown to directly contact TBP, the TATA box-binding subunit of the general initiation factor, TFIID. In this report, we use protein affinity chromatography to show that the cellular transcription factor, p53, interacts directly …
