A Broken α-Helix in Folded α-Synuclein
Open accessAbstract
alpha-Synuclein is a small cytosolic protein of presynaptic nerve terminals composed of seven 11-residue repeats and a hydrophilic tail. alpha-Synuclein misfolding and dysfunction may contribute to the pathogenesis of Parkinson's disease and neurodegenerative dementias, but its normal folding and function are unknown. In solution, alpha-synuclein is natively unstructured but assumes an alpha-helical conformation upon binding to phospholipid membranes. We now show that this conformation of alpha-synuclein consists of two alpha-helical regions that are interrupted by a short break. The structural organization of the alpha-helices of alpha-synuclein was not anticipated by sequence analyses and may be important for its pathogenic role.

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.
