Authors: Christopher H S Aylett / Evelyn Sauer / Stefan Imseng / Daniel Boehringer / Michael N Hall / Nenad Ban / Timm Maier / Abstract: Target of rapamycin (TOR), a conserved protein kinase and central controller of cell growth, functions in two structurally and functionally distinct complexes: TORC1 and TORC2. Dysregulation of ...Target of rapamycin (TOR), a conserved protein kinase and central controller of cell growth, functions in two structurally and functionally distinct complexes: TORC1 and TORC2. Dysregulation of mammalian TOR (mTOR) signaling is implicated in pathologies that include diabetes, cancer, and neurodegeneration. We resolved the architecture of human mTORC1 (mTOR with subunits Raptor and mLST8) bound to FK506 binding protein (FKBP)-rapamycin, by combining cryo-electron microscopy at 5.9 angstrom resolution with crystallographic studies of Chaetomium thermophilum Raptor at 4.3 angstrom resolution. The structure explains how FKBP-rapamycin and architectural elements of mTORC1 limit access to the recessed active site. Consistent with a role in substrate recognition and delivery, the conserved amino-terminal domain of Raptor is juxtaposed to the kinase active site. | |||||||||

Details | Poor quality micrographs were rejected by eye, based on the extent and regularity of the Thon rings observed in the contrast transfer function. Estimation of the contrast transfer function was carried out for each image using CTFFIND3, particles were selected semi-automatically using boxer and batchboxer. |
