Chemical screening of an inhibitor for gibberellin receptors based on a yeast two-hybrid system

Bioorg Med Chem Lett. 2013 Feb 15;23(4):1096-8. doi: 10.1016/j.bmcl.2012.12.007. Epub 2012 Dec 14.

Abstract

We applied a yeast two-hybrid (Y2H) system to the high-throughput monitoring of two proteins' interaction, a receptor for phytohormone gibberellin (GA) and its direct signal transducer DELLA. With this system, we screened inhibitors to the interaction. As a result, we discovered a chemical, 3-(2-thienylsulfonyl)pyrazine-2-carbonitrile (TSPC), and we confirmed that TSPC is an inhibitor for GA perception by in vitro and in planta evaluations.
