Amyloid beta (A4) precursor protein degradation products

... two ways. Α-secretase pathway: (1), also known as non-amyloid formation routes. Followed by the alpha, gamma secretase cutting, resulting in the exocytosis of APP (s APP alpha), P3 ~ 40 (A beta 17 or A beta 17 ~ 42) fragment and APP intracellular domain fragment. The role of the α-secretase enzyme ...
