The C‐Terminus of the β Protein is Critical in Amyloidogenesisa
Abstract
The β amyloid protein found in extracellular deposits in Alzheimer's disease (AD) is heterogeneous at its C‐terminus; proteins ending at residues 40, 42, and 43 have been identified in neuritic deposits, while protein in vascular amyloid appears to end at residue 39 or 40. Studies of synthetic β proteins (β1–39, β1–40, β1–42), and model peptides (β26–39, β26–40, β26–42, β26–43) demonstrate that amyloid formation is a nucleation‐dependent phenomenon. Peptides ending at residues 39 or 40 were kinetically soluble for hours to days, while peptides ending at residues 42 or 43 aggregated immediately; all eventually reached similar thermodynamic solubility. The kinetically soluble variants could be seeded with the kinetically insoluble variants. The secondary structure of β26–39 fibrils was different from that of β26–42 fibrils, however, seeding β26–39 with β26–42 produces mixed fibrils with structure similar to β26–42. These results suggest that neuritic plaques may be seeded by their minor component; this may determine the structure and properties of amyloid in AD.

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.
