Recognition and reprogramming of E3 ubiquitin ligase surfaces by α-helical peptides | Nature Communications

Identification of molecules that induce novel interactions between proteins has been limited by the complexity of rationally designing interactions. The authors report a method to discover molecular glue-like “trimerizers” based on α-helically constrained peptides that can co-opt the surfaces of E3 ubiquitin ligases to bind therapeutically important proteins.

Here, we report a general and rapid method for discovering α-helically constrained (Helicon) polypeptides that cooperatively induce the
