Directing the Mediator Complex: Bivalent approaches to Reconstituting or Inhibiti

点击翻译按钮获取中文摘要

DESCRIPTION (provided by applicant): This project combines the expertise of three different investigators in an orchestrated effort to address the NCI Provocative Question #18: "Are there new technologies to inhibit traditionally 'undruggable' target molecules, such as transcription factors, that are required for the oncogenic phenotype?" To address this question, we will develop three distinct, but synergistic, chemistries to provide new molecules that perturb undruggable targets such as transcription factors. In concert, we will evaluate their access to targets within cells and define the structural features that code for cellular access. These concepts will be developed in the context of the p53 transcription factor, a quintessential anti-cancer target, and its effects on the MED17 subunit of the Mediator complex.
