dc.description.abstract | The R2TP/Prefoldin-like co-chaperone, in concert with HSP90, facilitates assembly and cellular stability of RNA polymerase II, and complexes of PI3-kinase-like kinases such as mTOR. However, the mechanism by which this occurs is poorly understood. Here we use cryo-EM and biochemical studies on the human R2TP core (RUVBL1-RUVBL2-RPAP3-PIH1D1) which reveal the distinctive role of RPAP3, distinguishing metazoan R2TP from the smaller yeast equivalent. RPAP3 spans both faces of a single RUVBL ring, providing an extended scaffold that recruits clients and provides a flexible tether for HSP90. A 3.6 Å cryo-EM structure reveals direct interaction of a C-terminal domain of RPAP3 and the ATPase domain of RUVBL2, necessary for human R2TP assembly but absent from yeast. The mobile TPR domains of RPAP3 map to the opposite face of the ring, associating with PIH1D1, which mediates client protein recruitment. Thus, RPAP3 provides a flexible platform for bringing HSP90 into proximity with diverse client proteins. | es_ES |

Preliminary work used the platforms of the Grenoble Instruct-ERIC Center (ISBG: UMS 3518 CNRS-CEA-UGA- EMBL) with support from FRISBI (ANR-10-INSB-05-02) and GRAL (ANR-10-LABX-49- 01) within the Grenoble Partnership for Structural Biology (PSB). The electron micro- scope facility is supported by the Rhône-Alpes Region, the Fondation Recherche Medicale (FRM), the funds FEDER, the CEA, and the GIS-Infrastrutures en Biologie Sante et Agronomie (IBISA). We also acknowledge the help of Guy Schoehn (IBS-Grenoble). INSTRUCT and iNEXT supported access to the cryo-EM facilities. We thank the EM Units of the CIB-CSIC and the CNIO for support in preparing and screening the grids. | es_ES |
