We have investigated the membrane remodeling capacity of the N-terminal membrane-binding domain of α-synuclein (α-Syn100). Using fluorescence correlation spectroscopy and vesicle clearance assays, we show that α-Syn100 fully tubulates POPG vesicles, the first demonstration that the amphipathic helix on its own is capable of this effect. We also show that at(More)
α-Synuclein is the primary protein found in Lewy bodies, the protein and lipid aggregates associated with Parkinson’s disease and Lewy body dementia. The protein folds into a uniquely long amphipathic α-helix (AH) when bound to a membrane, and at high enough concentrations, it induces large-scale remodeling of membranes (tubulation and vesiculation).
