ABSTRACT:
The invention provides polynucleotides and polypeptides encoding an isolated amyloid inhibitor protein (APIP) and compositions thereof. The polypeptides of the subject invention can be used to inhibit the catabolism or sequential cleavage of amyloid beta precursor protein (APP) by sequential cleavage of APP by beta secretase and gamma secretase.
