Abstract
α‐Synuclein (α‐syn) protein has been found in association with the pathological lesions of a number of neurodegenerative diseases. Recently, mutations in the α‐syn gene have been reported in families susceptible to an inherited form of Parkinson's disease. We report here that human wild‐type α‐syn, PD‐linked mutant α‐syn(Ala30Pro) and mutant α‐syn(Ala53Thr) proteins can self‐aggregate and form amyloid‐like filaments. The mutant α‐syn forms more β‐sheet and mature filaments than the wild‐type protein. These findings suggest that accumulation of α‐syn as insoluble deposits of amyloid may play a major role in the pathogenesis of these neurodegenerative diseases.Keywords
