摘要： Provided are methods of identifying inhibitors of β-secretase that employ modified β-secretase substrates. The modified β-secretase substrates have β-secretase cleavage sites that are altered from wild type. The amino acid sequences of the altered β-secretase cleavage sites contain different amino acids in at least one of the positions P2-P1-P1′-P2′ of the β-secretase cleavage site. Many of the modified β-secretase substrates are more efficient substrates for β-secretase than are corresponding substrates having wild-type sequences, that is, these modified substrates are more susceptible to enzymatic breakdown by β-secretase. Recombinant polynucleotide molecules encoding the modified β-secretase substrates are provided. Antibodies that recognize cleavage products of the modified β-secretase substrates are provided. Stable cell lines expressing the modified β-secretase substrates are provided. Transgenic animals expressing the modified β-secretase substrates are provided.

摘要： Polypeptide substrates based on modifications or fragments of the various APP isoforms, assay methods based on the use of these substrates, and screening methods directed toward identifying inhibitors of γ-secretase activity. The assay methods and the screening methods are adapted for use in high throughput multi-well plate assay apparatuses. In many embodiments the substrate polypeptides are labeled for ease of detection, and/or may bind specific ligands that themselves are labeled. Generally the labels promote high specificity as well as high sensitivity of detection. These features render the assay and screening methods that employ the labeled substrates especially suited for use in high throughput assay formats. This disclosure further identifies small polypeptides based on a subsequence motif of Aβ that are shown herein to be potent inhibitors of the activity of γ-secretase.
