Aptamer and N-Degron Ensemble (AptaGron) as a Target Protein Degradation Strategy.

ABSTRACT: Target protein degradation (TPD) is a promising strategy for catalytic downregulation of target proteins through various cellular proteolytic pathways. Despite numerous reports on novel TPD mechanisms, the discovery of target-specific ligands remains a major challenge. Unlike small-molecule ligands, aptamers offer significant advantages, owing to their SELEX-based systematic screening method. To fully utilize aptamers for TPD, we designed an aptamer and N-degron ensemble system (AptaGron) that circumvents the need for synthetic conjugations between aptamers and proteolysis-recruiting units. In our AptaGron system, a peptide nucleic acid containing an N-degron peptide and a sequence complementary to the aptamer was designed. Using this system, we successfully degraded three target proteins,
