Allelic interference: a mechanism for trans-dominant transmission of loss of function in the neurodegeneration of familial Alzheimer's disease.

Abstract excerpt

Presenilins (PSs) are catalytic components of the γ-secretase complexes that promote the ε-cleavage of cell surface proteins producing cytosolic peptides shown to function in cell signaling and gene expression. In addition, secretase cleavages at γ-sites of amyloid precursor protein substrates produce the amyloid-β (Aβ) peptides found in all people. Aggregation of Aβ peptides form the amyloid fibrils found in...
