引用 | ジャーナル: Nature / 年: 2020タイトル: NEDD8 nucleates a multivalent cullin-RING-UBE2D ubiquitin ligation assembly. 著者: Kheewoong Baek / David T Krist / J Rajan Prabu / Spencer Hill / Maren Klügel / Lisa-Marie Neumaier / Susanne von Gronau / Gary Kleiger / Brenda A Schulman / ![]() 要旨: Eukaryotic cell biology depends on cullin-RING E3 ligase (CRL)-catalysed protein ubiquitylation, which is tightly controlled by the modification of cullin with the ubiquitin-like protein NEDD8. ...Eukaryotic cell biology depends on cullin-RING E3 ligase (CRL)-catalysed protein ubiquitylation, which is tightly controlled by the modification of cullin with the ubiquitin-like protein NEDD8. However, how CRLs catalyse ubiquitylation, and the basis of NEDD8 activation, remain unknown. Here we report the cryo-electron microscopy structure of a chemically trapped complex that represents the ubiquitylation intermediate, in which the neddylated CRL1 promotes the transfer of ubiquitin from the E2 ubiquitin-conjugating enzyme UBE2D to its recruited substrate, phosphorylated IκBα. NEDD8 acts as a nexus that binds disparate cullin elements and the RING-activated ubiquitin-linked UBE2D. Local structural remodelling of NEDD8 and large-scale movements of CRL domains converge to juxtapose the substrate and the ubiquitylation active site. These findings explain how a distinctive ubiquitin-like protein alters the functions of its targets, and show how numerous NEDD8-dependent interprotein interactions and conformational changes synergistically configure a catalytic CRL architecture that is both robust, to enable rapid ubiquitylation of the substrate, and fragile, to enable the subsequent functions of cullin-RING proteins. | ||||||
