abstract：:γ-Secretase is a membrane-embedded protease complex with presenilin as the catalytic component. Cleavage within the transmembrane domain of the amyloid β-protein precursor (APP) by γ-secretase produces the C-terminus of the amyloid β-peptide (Aβ), a proteolytic product prone to aggregation and strongly linked to Alzhe...
