![]() | ![]() タイトル: EGOC inhibits TOROID polymerization by structurally activating TORC1. 著者: Manoël Prouteau / Clélia Bourgoint / Jan Felix / Lenny Bonadei / Yashar Sadian / Caroline Gabus / Savvas N Savvides / Irina Gutsche / Ambroise Desfosses / Robbie Loewith / ![]() ![]() ![]() 要旨: Target of rapamycin complex 1 (TORC1) is a protein kinase controlling cell homeostasis and growth in response to nutrients and stresses.

In Saccharomyces cerevisiae, glucose depletion triggers a redistribution of TORC1 from a dispersed localization over the vacuole surface into a large, inactive condensate called TOROID (TORC1 organized in inhibited domains). However, the mechanisms governing this transition have been unclear. Here, we show that acute depletion and repletion of EGO complex (EGOC) activity is sufficient to control TOROID distribution, independently of other nutrient-signaling pathways. The 3.9-Å-resolution structure of TORC1 from TOROID cryo-EM data together with interrogation of key interactions in vivo provide structural insights into TORC1-TORC1' and TORC1-EGOC interaction interfaces. These data support a model in which glucose-dependent activation of EGOC triggers binding to TORC1 at an interface required for TOROID assembly, preventing TORC1 polymerization and promoting release of active TORC1. | |||||||||||||||

Next, we employed the localrec module in Scipion to crop and re-center the signal subtracted particles in a smaller box of 300 pixels, as well as assigning to each particle a refined defocus based on the helical geometry. Single-particle analysis of the subtracted particles using 3D refinement in RELION2.0, while imposing D1 symmetry, resulted in a map with a resolution of 4.5 Angstrom (FSC = 0.143). We then imported the particles from the RELION2.0 refinement in cryoSPARC 3.01. After 2D classification and class selection, a set of 213808 selected particles was used for Non-Uniform refinement in cryoSPARC 3.01, employing a dynamic mask, imposing D1 symmetry, using the option to keep particles from the same helix in the same half-set, and allowing high-order aberration estimation and correction, which resulted in a final map with a resolution of 3.87 Angstrom (FSC = 0.143). 対称性のタイプ: POINT | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Homology models of Tor2, Lst8 and Kog1 were first manually placed in the final 3D map followed by rigid-body fitting in Chimera. The rigid-body fitted models were subsequently subjected to a round of flexible fitting using Imodfit followed by automatic molecular dynamics flexible fitting using NAMDINATOR. The flexibly fitted structure was then refined using the Phenix software package. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
