A Parkinson's disease-related double mutant (A30P/A53T) of alpha-synuclein. The recombinant protein was purified to apparent homogeneity by taking advantage of the thermosolubility of the protein and by using conventional column chromatography techniques. Alternative Names: NACP protein, SNCA protein, PD1 protein, precursor of PARK 1 protein, alpha-Synuclein protein, Non-A4 component of amyloid precursor protein, , Non A4 component of amyloid precursor protein, Synuclein alpha protein, Non A beta component of AD amyloid protein, alphaSYN protein, PD 1 protein, Alpha synuclein protein, PARK4 protein, MGC110988 protein, PARK1 protein, Alpha-synuclein isoform NACP140 protein, MGC105443 protein, PARK 4 protein, MGC127560 protein, Non-A beta component of AD amyloid protein, Non-A-beta component of alzheimers disease amyloid protein, Parkinson disease familial 1 protein, MGC64356 protein
