Plant UVR8 Photoreceptor Senses UV-B by Tryptophan-Mediated Disruption of Cross-Dimer Salt Bridges
Open accessAbstract
Donuts Dissociate: In Arabidopsis , the UVR8 protein responds to ultraviolet-B (UV-B) light by dissociating into monomers, which are then available to interact with downstream factors that enact the plant's response to light. Christie et al. (p. 1492 , published online 9 February; see the cover and see the Perspective by Gardner and Correa ) have now determined the crystal structure of UVR8. Without ultraviolet-B light, UVR8 dimerizes, with two donut-shaped monomers joined by a network of salt bridges. Close-packing of a pyramid of tryptophan residues permits exciton coupling that is key to UV-B perception. Electron transfer after UV-B perception could dissociate the salt bridges that hold the dimer together and release monomeric UVR8 to initiate light-induced signaling.

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.
