Enhancing the arsenal of E3 ligases is important for PROTACs development. Here, the authors identify a non-inhibitory aptameric ligand to CRL2ZYG11B E3 ligase, and develop a general, modular, and straightforward aptamer-based PROTAC platform, termed ZATAC, providing insights for untapped E3 ligases.
