KCTD5, a pentameric substrate receptor protein consisting of an N-terminal BTB domain and a C- ...Heterotrimeric G proteins can be regulated by posttranslational modifications, including ubiquitylation. KCTD5, a pentameric substrate receptor protein consisting of an N-terminal BTB domain and a C-terminal domain, engages CUL3 to form the central scaffold of a cullin-RING E3 ligase complex (CRL3) that ubiquitylates Gβγ and reduces Gβγ protein levels in cells. The cryo-EM structure of a 5:5:5 KCTD5/CUL3/Gβγ assembly reveals a highly dynamic complex with rotations of over 60° between the KCTD5/CUL3 and KCTD5/Gβγ moieties of the structure. CRL3 engages the E3 ligase ARIH1 to ubiquitylate Gβγ in an E3-E3 superassembly, and extension of the structure to include full-length CUL3 with RBX1 and an ARIH1~ubiquitin conjugate reveals that some conformational states position the ARIH1~ubiquitin thioester bond to within 10 Å of lysine-23 of Gβ and likely represent priming complexes. Most previously described CRL/substrate structures have consisted of monovalent complexes and have involved flexible peptide substrates. The structure of the KCTD5/CUL3/Gβγ complex shows that the oligomerization of a substrate receptor can generate a polyvalent E3 ligase complex and that the internal dynamics of the substrate receptor can position a structured target for ubiquitylation in a CRL3 complex. #1: ![]() タイトル: Structure and dynamics of a pentameric KCTD5/Cullin3/G beta gamma E3 ubiquitin ligase complex 著者: Nguyen, D.M. / Rath, D.H. / Devost, D. / Petrin, D. / Rizk, R. / Ji, A.X. / Narayanan, N. / Yong, D. / Zhai, A. / Kuntz, D.A. / Mian, M.U.Q. / Pomroy, N.C. / Keszei, A.F.E. / Benlekbir, S. / ...著者: Nguyen, D.M. / Rath, D.H. / Devost, D. / Petrin, D. / Rizk, R. / Ji, A.X. / Narayanan, N. / Yong, D. / Zhai, A. / Kuntz, D.A. / Mian, M.U.Q. / Pomroy, N.C. / Keszei, A.F.E. / Benlekbir, S. / Mazhab-Jafari, M.T. / Rubinstein, J.L. / Hebert, T.E. / Prive, G.G. #2: ![]() タイトル: Structure and dynamics of a pentameric KCTD5/Cullin3/G beta gamma E3 ubiquitin ligase complex 著者: Nguyen, D.M. / Rath, D.H. / Devost, D. / Petrin, D. / Rizk, R. / Ji, A.X. / Narayanan, N. / Yong, D. / Zhai, A. / Kuntz, D.A. / Mian, M.U.Q. / Pomroy, N.C. / Keszei, A.F.E. / Benlekbir, S. / ...著者: Nguyen, D.M. / Rath, D.H. / Devost, D. / Petrin, D. / Rizk, R. / Ji, A.X. / Narayanan, N. / Yong, D. / Zhai, A. / Kuntz, D.A. / Mian, M.U.Q. / Pomroy, N.C. / Keszei, A.F.E. / Benlekbir, S. / Mazhab-Jafari, M.T. / Rubinstein, J.L. / Hebert, T.E. / Prive, G.G. | ||||||
