| Outline of Final Research Achievements |
Synthetic compounds that control the structural changes and interactions of intrinsically disordered proteins (IDPs) are expected to be a breakthrough that paves the way for new drug discovery. However, details of IDPs are still unknown, and almost no inhibitors that specifically disrupt IDP’s functions have been found. In this study, we focused on the Circadian Clock transcription factors Clock and Bmal 1 that are known as typical IDPs in which more than 30% in length are highly disordered. We obtained truncated version of recombinant Clock and Bmal1, and constructed a system of fluorescent polarization assay for heterodimer formation of Clock/Bmal 1. As a result of evaluation of low-molecular-weight aromatic compound library, we succeeded in finding a compound which significantly inhibits intermolecular interaction of Clock / Bmal1.
