MRNA PROTACs: engineering PROTACs for high-efficiency targeted protein degradation.

ABSTRACT: Proteolysis-targeting chimeras (PROTACs) are essential bifunctional molecules that target proteins of interest (POIs) for degradation by cellular ubiquitination machinery. Despite significant progress made in understanding PROTACs' functions, their therapeutic potential remains largely untapped. As a result of the success of highly flexible, scalable, and low-cost mRNA therapies, as well as the advantages of the first generation of peptide PROTACs (p-PROTACs), we present for the first time an engineering mRNA PROTACs (m-PROTACs) strategy. This design combines von Hippel-Lindau (VHL) recruiting peptide encoding mRNA and POI-binding peptide encoding mRNA to form m-PROTAC and promote cellular POI degradation. We then performed proof-of-concept experiments using two m-PROTACs targeting two can
