Peptides derived from cadherin and methods of use thereof
View Patent ↗The present invention provides polypeptides and peptides derived from cadherin. The polypeptides and peptides are useful in a method of inhibiting amyloid deposition and a method of inhibiting tumor metastasis. A method of determining susceptibility to Alzheimer's disease and a method of screening for agents that modify cadherin processing are also provided.
1. A peptide that binds to presenilin-1 and comprises the sequence EGGGE (SEQ ID NO: 5) wherein the peptide is from five to fifteen amino acids in length.
2. The peptide of claim 1 comprising a sequence selected from the group consisting of EGGGEEDQDFDL (SEQ ID NO: 1), EGGGEMDTTSYD (SEQ ID NO: 2), EGGGEEDQDYDLS (SEQ ID NO: 3) and EGGGEED (SEQ ID NO: 4).
3. A composition comprising the peptide of claim 1 .
4. A method of inhibiting Presenilin-1-mediated γ-secretase activity comprising contacting a cell capable of exhibiting such activity with the composition of claim 1 .
