How does amyloid beta form
WebBeta-amyloid is the product of the sequential proteolytic digestion of the transmembrane protein APP. In the amyloidogenic pathway, the cleavage of APP is mediated first by BACE1 and, subsequently, by γ-secretase leading to the release of β-amyloid monomers, which are actively degraded by IDE, NEP, and ECE enzymes.
