Small-molecule heterobifunctional degraders can effectively control protein levels and are useful research tools. We assembled proteolysis targeting chimeras (PROTACs) from a cereblon (CRBN) and a von-Hippel-Lindau (VHL) ligase ligand and demonstrated a PROTAC-induced heterodimerization of the two E3 ligases leading to unidirectional and efficient degradation of CRBN.
