Proprotein convertase activity contributes to the processing of the Alzheimer's beta-amyloid precursor protein in human cells: evidence for a role of the prohormone convertase PC7 in the constitutive alpha-secretase pathway.

Abstract excerpt

The physiological maturation of the beta-amyloid precursor protein (betaAPP) leads to the secretion of a fragment termed APPalpha, after cleavage by a proteolytic enzyme called-secretase. In Alzheimer's disease, betaAPP undergoes exacerbated proteolytic attacks by beta- and gamma-secretases, which liberate a readily aggregatable 40-42-amino acid peptide called AP. We show here that overexpression of the...
