Journal ArticleDOI
Structural and Functional Analysis of SGT1 Reveals That Its Interaction with HSP90 Is Required for the Accumulation of Rx, an R Protein Involved in Plant Immunity
Marta Boter,Béatrice Amigues,Jack R. Peart,Christian Breuer,Yasuhiro Kadota,Catarina Casais,Geoffrey R. Moore,Colin Kleanthous,Françoise Ochsenbein,Ken Shirasu,Raphael Guerois +10 more
TL;DR: Structural and functional characterization of plant SGT1 proteins and biochemical reconstitution experiments suggest that RAR1 may function to enhance the SGT 1–HSP90 interaction by promoting ternary complex formation.
Journal ArticleDOI
RanGAP2 Mediates Nucleocytoplasmic Partitioning of the NB-LRR Immune Receptor Rx in the Solanaceae, Thereby Dictating Rx Function
Wladimir I. L. Tameling,Claudia Nooijen,Nora R. Ludwig,Marta Boter,E.J. Slootweg,Aska Goverse,Ken Shirasu,Matthieu H. A. J. Joosten +7 more
TL;DR: The data show that a balanced nucleocytoplasmic partitioning of Rx is required for proper regulation of defense signaling and indicate that RanGAP2 regulates this partitioning by serving as a cytop lasmic retention factor for Rx.
Journal ArticleDOI
Structural and functional coupling of Hsp90- and Sgt1-centred multi-protein complexes.
Minghao Zhang,Marta Boter,Kuoyu Li,Yasuhiro Kadota,Barry Panaretou,Chrisostomos Prodromou,Ken Shirasu,Laurence H. Pearl +7 more
TL;DR: It is shown that Sgt1 bridges the Hsp90 molecular chaperone system to the substrate‐specific arm of SCF ubiquitin ligase complexes, suggesting a role in SCF assembly and regulation, and providing multiple complementary routes for ubiquitination of Hsp 90 client proteins.
Journal ArticleDOI
TPR-Mediated Self-Association of Plant SGT1†
Afua Nyarko,Khédidja Mosbahi,Arthur J. Rowe,Andrew P. Leech,Marta Boter,Ken Shirasu,Colin Kleanthous +6 more
TL;DR: This study, which provides the first biophysical characterization of plant Sgt1, highlights how TPR domains can mediate self-association in solution and that sequence variation in the regions involved in oligomerization affects the propensity of TPR-containing proteins to dimerize.
Journal ArticleDOI
Biochemical Characterization of RAR1 Cysteine- and Histidine-Rich Domains (CHORDs): A Novel Class of Zinc-Dependent Protein−Protein Interaction Modules†
Charles T. Heise,Cécile S. Le Duff,Marta Boter,Catarina Casais,Joanne E. Airey,Andrew P. Leech,Béatrice Amigues,Raphaël Guerois,Geoffrey R. Moore,Ken Shirasu,Colin Kleanthous +10 more
TL;DR: This study provides the first biochemical and biophysical data on the zinc metalloprotein RAR1, defines its metal stoichiometry and that of its constituent CHORDs, and reveals that the metal ions are essential for structural integrity and specific protein-protein associations.
