Regulation of Dynein-Driven Microtubule Sliding by the Radial Spokes in Flagella
Abstract
The regulation of microtubule sliding in flagellar axonemes was studied with the use of Chlamydomonas mutants and in vitro assays. Microtubule sliding velocities were diminished in axonemes from mutant cells missing radial spoke structures but could be restored upon reconstitution with dynein from axonemes with wild-type radial spokes. These experiments demonstrate that the radial spokes activate dynein's microtubule sliding activity.

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.
