摘要: Compositions comprising a novel protease capable of cleaving .beta.-amyloid precursor protein on the amino-terminal side of the .beta.-amyloid peptide therein are provided. The protease is designated .beta.-secretase. The .beta.-secretase may be used in screening assays to identify .beta.-secretase inhibitors, or the .beta.-secretase is combined with a suitable polypeptide substrate and cleavage of the substrate determined in the presence and absence of the test substance.

摘要: Compositions comprising a novel protease capable of cleaving β-amyloid precursor protein (APP) on the amino-terminal side of the β-amyloid peptide therein are provided. The protease is designated β-secretase. Reaction systems comprising β-secretase may be used in screening assays to monitor β-secretase modulated cleavage of APP and to identify β-secretase inhibitors, wherein the β-secretase is in the presence of a suitable polypeptide substrate and cleavage of the substrate determined in the presence and absence of the test substance. Antibodies are raised against peptides of β-secretase. Pharmaceutical compositions and methods comprise compounds identified by screening assays.
