The impaired ubiquitin-proteasome activity is believed to be one of the leading factors that contribute to Parkinson disease pathogenesis partially by causing alpha-synuclein aggregation. However, the relationship between alpha-synuclein aggregation and the impaired proteasome activity is yet unclear. In this study, we examined the effects of three soluble alpha-synuclein species (monomer, dimer, and protofibrils) on the degradation activity of the 26 S proteasome by reconstitution of… CONTINUE READING
