One hypothesis for the etiology of Parkinson's disease (PD) is that subsets of neurons are vulnerable to a failure in proteasome-mediated protein turnover. Here we show that overexpression of mutant alpha-synuclein increases sensitivity to proteasome inhibitors by decreasing proteasome function. Overexpression of parkin decreases sensitivity to proteasome(More)
Synphilin-1 has been shown to interact with alpha-synuclein, which in turn is associated with Parkinson's disease. However, the function of synphilin-1 is unknown. We have cloned mouse synphilin in an attempt to describe conserved and therefore likely functional domains. The deduced amino acid sequence of the protein shows extensive homology with its human(More)
