Discovery of a Natural Ent-Kaurene Diterpenoid Oridonin as an E3 Ligase Recruiter for PROTACs.

PROTACs have emerged as a therapeutic modality for the targeted degradation of proteins of interest (POIs). Central to PROTAC technology are the E3 ligase recruiters, yet only a few of them have been identified due to the lack of ligandable pockets in ligases, especially among single-subunit ligases. We propose that binders of partner proteins of single-subunit ligases could be repurposed as new ligase recruiters.
