Atomic structure of Hsp90-Cdc37-Cdk4 reveals that Hsp90 traps and stabilizes an unfolded kinase
Open accessPublished version of a preprint
Abstract
Holding kinases at the ready: About 60% of kinases only reach their active state in the presence of the molecular chaperone Hsp90 and its co-chaperone Cdc37. It is unclear how the chaperones facilitate kinase function or why only some kinases are chaperone-dependent. Verba et al. determined a 3.9 Å cryo–electron microscopy structure of Hsp90:Cdc37 in complex with the kinase Cdk4. Together, Hsp90 and Cdc37 trap the kinase in an open, partially unfolded state. Taking on this state probably has direct functional benefits. Science , this issue p. 1542

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
