タイトル: Atomic structure of Hsp90-Cdc37-Cdk4 reveals that Hsp90 traps and stabilizes an unfolded kinase.

要旨: The Hsp90 molecular chaperone and its Cdc37 cochaperone help stabilize and activate more than half of the human kinome. However, both the mechanism by which these chaperones assist their "client" ...The Hsp90 molecular chaperone and its Cdc37 cochaperone help stabilize and activate more than half of the human kinome. However, both the mechanism by which these chaperones assist their "client" kinases and the reason why some kinases are addicted to Hsp90 while closely related family members are independent are unknown. Our structural understanding of these interactions is lacking, as no full-length structures of human Hsp90, Cdc37, or either of these proteins with a kinase have been elucidated. Here we report a 3.9 angstrom cryo-electron microscopy structure of the Hsp90-Cdc37-Cdk4 kinase complex. Surprisingly, the two lobes of Cdk4 are completely separated with the β4-β5 sheet unfolded. Cdc37 mimics part of the kinase N lobe, stabilizing an open kinase conformation by wedging itself between the two lobes. Finally, Hsp90 clamps around the unfolded kinase β5 strand and interacts with exposed N- and C-lobe interfaces, protecting the kinase in a trapped unfolded state. On the basis of this structure and an extensive amount of previously collected data, we propose unifying conceptual and mechanistic models of chaperone-kinase interactions.

画像解析

詳細Image stacks were corrected for motion and summed as described previously, resulting in binned sums (1.315A/pix). For particle picking the images were binned to 5.2A/pix and Gaussian bandpass filtered between 15A and 500A using EMAN2. SamViewer template based picking was then used to pick particles from all the micrographs, followed by manual review of all the picks. After such procedure 802877 particles were picked in total and extracted from images binned to 2.6A/pix. CTFFIND4 was used to estimate defocus parameters for all the images. Relion 1.4 was used for all the following steps unless noted otherwise. Reference free 2D classification into 300 classes for 75 iterations was performed followed by manual examination of the resulting class averages. Low resolution/signal to noise/feature class averages and contributing particles were discarded, resulting in 670000 particles left. The resulting particles were 3D classified into 4 classes resulting in two classes having high-resolution features (390000 particles). At this stage particles were extracted from 1.315A/pix micrographs and all the following processing was done with these particles. Using 3D Auto-refine in Relion 1.4, a reconstruction was obtained from 390000 particles resulting from 3D classification above (using highest resolution 3D class as initial model, low pass filtered to 20A). Using the resulting parameters, the particles were further drift corrected per particle and dose weighted using the Particle Polishing feature. The B-factor weighing curve was fit by a polynomial (with a rationale that such a curve should be smooth) and used to generate new weighting parameters for Particle Polishing, with which 390000 particles were then polished. All further data processing was done using the polished particles. Re-refinement of the 390000 particles after polishing yielded the map at about 4A resolution (determined using gold standard FSC in the PostProcessing tab). Raw particles were sharpened with a B-factor of -50, low pass filtered with Gaussian filter to 3A and the refinement was continued for 10 more iterations (until convergence) with these particles (the rationale was that due to extremely low noise levels of K2 direct detector, this would yield more accurate alignments due to presence of more high resolution data in the images). This resulted in similar resolution but one with visually sharper features.

EMDBのIDの桁数の変更

  • EMDBエントリに付与されているアクセスコード(EMDB-ID)は4桁の数字(例、EMD-1234)でしたが、間もなく枯渇します。これまでの4桁のID番号は4桁のまま変更されませんが、4桁の数字を使い切った後に発行されるIDは5桁以上の数字(例、EMD-12345)になります。5桁のIDは2019年の春頃から発行される見通しです。
  • EM Navigator/万見では、接頭語「EMD-」は省略されています。
