Abstract

Coupling between ATPase and track binding sites is essential for molecular motors to move along cytoskeletal tracks. In dynein, these sites are separated by a long coiled coil stalk that must mediate communication between them, but the underlying mechanism remains unclear. Here we show that changes in registration between the two helices of the coiled coil can perform this function. We locked the coiled coil at three specific registrations using oxidation to disulfides of paired cysteine residues introduced into the two helices. These trapped ATPase activity either in a microtubule-independent high or low state, and microtubule binding activity either in an ATP-insensitive strong or weak state, depending on the registry of the coiled coil. Our results provide direct evidence that dynein uses sliding between the two helices of the stalk to couple ATPase and microtubule binding activities during its mechanochemical cycle.

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.
