PROTAC (proteolysis-targeting chimeras) is a rapidly evolving technology to target undruggable targets. The mechanism by which this happens is when a bifunctional molecule binds to a target protein and also brings an E3 ubiquitin ligase in proximity to trigger ubiquitination and degradation of the target protein. Yet, in-silico-driven approaches to design these heterobifunctional molecules that have the desired functional properties to induce proximity between the target protein and E3 ligase remain to be established. In this paper, we present a novel in-silico method for PROTAC design and to demonstrate the validity of our approach, we show that for a BRD4-VHL-PROTAC-mediated ternary complex known in the literature, we are able to reproduce the PROTAC binding mode, the structure of the ternary complex formed therein, and the free energy (ฮ Show less
