A Triple-Emission Fluorescent Probe Reveals Distinctive Amyloid Fibrillar Polymorphism of Wild-Type α-Synuclein and Its Familial Parkinson’s Disease Mutants

8 Jul 2009

Abstract excerpt

Intracytoplasmic neuronal deposits containing amyloid fibrils of the 140-amino acid presynaptic protein alpha-synuclein (AS) are the hallmark of Parkinson's (PD) disease and related neurodegenerative disorders. Three point mutations (A53T, A30P, and E46K) are linked to early onset PD. Compared to the wild-type (WT) protein, the mutants aggregate faster in vitro, but their fibrillar products are quite similar....
