Authors: Xinyan Chen / Anat Raiff / Shanshan Li / Qiong Guo / Jiahai Zhang / Hualin Zhou / Richard T Timms / Xuebiao Yao / Stephen J Elledge / Itay Koren / Kaiming Zhang / Chao Xu / Abstract: The E3 ligase-degron interaction determines the specificity of the ubiquitin‒proteasome system.

We recently discovered that FEM1B, a substrate receptor of Cullin 2-RING ligase (CRL2), recognizes C-degrons containing a C-terminal proline. By solving several cryo-EM structures of CRL2 bound to different C-degrons, we elucidate the dimeric assembly of the complex. Furthermore, we reveal distinct dimerization states of unmodified and neddylated CRL2 to uncover the NEDD8-mediated activation mechanism of CRL2. Our research also indicates that, FEM1B utilizes a bipartite mechanism to recognize both the C-terminal proline and an upstream aromatic residue within the substrate. These structural findings, complemented by in vitro ubiquitination and in vivo cell-based assays, demonstrate that CRL2-mediated polyubiquitination and subsequent protein turnover depend on both FEM1B-degron interactions and the dimerization state of the E3 ligase complex. Overall, this study deepens our molecular understanding of how Cullin-RING E3 ligase substrate selection mediates protein turnover. | |||||||||
