ß-Sheet-rich aggregates of α-synuclein (αS) characterize Parkinson's disease (PD) and recent work suggests that αS exists as α-helix-rich tetramers and related low-nmultimers in normal cells. Here the authors show that αS mutations associated with familial PD decrease the intraneuronal tetramer:monomer ratio and are correlated with neurotoxicity.
