The crystal structures of thalidomide and its derivatives bound to the E3 ligase subcomplex DDB1–CRBN are shown; these drugs are found to have dual functions, interfering with the binding of certain cellular substrates to the E3 ligase but promoting the binding of others, thereby modulating the degradation of cellular proteins.
