Involvement of cell surface glycosyl-phosphatidylinositol-linked aspartyl proteases in alpha-secretase-type cleavage and ectodomain solubilization of human Alzheimer beta-amyloid precursor protein in yeast.

Abstract excerpt

Human beta-amyloid precursor protein (APP) introduced into yeast undergoes alpha-secretase-type cleavage, suggesting that yeast have alpha-secretase-like protease(s). Here we report that two structurally and functionally related glycosyl-phosphatidylinositol-linked yeast aspartyl proteases, Mkc7p and Yap3p (collectively termed yapsin), are responsible for alpha-secretase-type cleavage of APP expressed in yeast,...
