ABSTRACT:
The application identifies fragments of alpha-synuclein in patients with Lewy Body Disease (LBD) and transgenic animal models thereof. These diseases are characterized by aggregations of alpha-synuclein. The fragments have a truncated C-terminus relative to full-length alpha-synuclein. Some fragments are characterized by a molecular weight of about 12 kDa as determined by SDS gel electrophoresis in tricine buffer and a truncation of at least ten contiguous amino acids from the C-terminus of natural alpha-synuclein. The site of cleavage preferably occurs after residue 117 and before residue 126 of natural alpha-synuclein. The identification of these novel fragments of alpha-synuclein has a number of application in for example, drug discovery, diagnostics, therapeutics, and transgenic animals.
