Abstract

Plethora of Secretory Amyloids: Protein aggregation and the formation of amyloids are associated with several dozen pathological conditions in humans, including Alzheimer's disease, Parkinson's disease, and type II diabetes. In addition, a few functional amyloid systems are known: the prions of fungi, the bacterial protein curli, the protein of chorion of the eggshell of silkworm, and the amyloid protein Pmel-17 involved in mammalian skin pigmentation. Now Maji et al. (p. 328 , published online 18 June) propose that endocrine hormone peptides and proteins are stored in an amyloid-like state in secretory granules. Thus, the amyloid fold may represent a fundamental, ancient, and evolutionarily conserved protein structural motif that is capable of performing a wide variety of functions contributing to normal cell and tissue physiology.

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.
