Out of the ˜29 CRL4 substrate receptors reported, the DDB1- and CUL4- ...The cullin-4-based RING-type (CRL4) family of E3 ubiquitin ligases functions together with dedicated substrate receptors. Out of the ˜29 CRL4 substrate receptors reported, the DDB1- and CUL4-associated factor 1 (DCAF1) is essential for cellular survival and growth, and its deregulation has been implicated in tumorigenesis. We carried out biochemical and structural studies to examine the structure and mechanism of the CRL4 ligase. In the 8.4 Å cryo-EM map of CRL4 , four CUL4-RBX1-DDB1-DCAF1 protomers are organized into two dimeric sub-assemblies. In this arrangement, the WD40 domain of DCAF1 mediates binding with the cullin C-terminal domain (CTD) and the RBX1 subunit of a neighboring CRL4 protomer. This renders RBX1, the catalytic subunit of the ligase, inaccessible to the E2 ubiquitin-conjugating enzymes. Upon CRL4 activation by neddylation, the interaction between the cullin CTD and the neighboring DCAF1 protomer is broken, and the complex assumes an active dimeric conformation. Accordingly, a tetramerization-deficient CRL4 mutant has higher ubiquitin ligase activity compared to the wild-type. This study identifies a novel mechanism by which unneddylated and substrate-free CUL4 ligases can be maintained in an inactive state. | |||||||||
