Parkin and Its Substrates

Abstract: Science 293, 224-225 (2001).

What causes the selective degeneration of nigrostriatal dopaminergic neurons in the brains of Parkinson's disease patients? A clue comes from new work showing that two proteins implicated in Parkinson's disease, parkin and {alpha}-synuclein, normally interact in healthy neurons. The authors speculate that defective targeting of {alpha}-synuclein for degradation by parkin results in the accumulation of toxic {alpha}-synuclein aggregates that selectively kill dopaminergic neurons.
