Abstrakt: The article looks at the creation of carboxyl terminal (C-terminal) fragments of the Alzheimer amyloid β-protein precursor (APP) by cleavage by the γ-secretase enzyme, with particular focus on amino acid lengths of C-terminal fragments related to familial Alzheimer's disease (FAD) genetic mutations of APP and presenilin 1 protein. It is suggested that FAD mutations inhibit the cleavage activity of γ-secretase and promote the pathogenesis of Alzheimer's disease.
