Aph-1, Pen-2, and Nicastrin with Presenilin Generate an Active γ-Secretase Complex

Open access
De Strooper, Bart·2003·Neuron

Abstract

Gamma-Secretase cleaves the Amyloid Precursor Protein (APP) in its transmembrane domain, releasing the amyloid peptide Abeta. Abeta is the main constituent of the amyloid plaques in the brains of patients suffering from Alzheimer's disease. Several other type I integral membrane proteins are also cleaved by this protease. Recent work indicates that gamma-Secretase is a multiprotein complex consisting of Presenilin, Nicastrin, Aph-1, and Pen-2 and that all four proteins are necessary for full proteolytic activity. Since several paralogs and alternatively spliced variants of at least Presenilin and Aph-1 have been identified as well, it is anticipated that gamma-Secretase is not a homogeneous activity. Gamma-Secretase is an interesting but complex drug target that challenges classical thinking about proteolytic processing and intracellular 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.
