Cullin-RING ligases (CRLs) compose the largest class of E3 ubiquitin ligases. CRLs are modular, multisubunit enzymes, comprising interchangeable substrate receptors dedicated to particular Cullin-RING catalytic cores. Recent structural studies have revealed numerous ways in which CRL E3 ligase activities are controlled, including multimodal E3 ligase activation by covalent attachment of the ubiquitin-like protein NEDD8, inhibition of CRL assembly/activity by CAND1, and several mechanisms of… CONTINUE READING
