A deletion mutant of alpha-synuclein (amino acids 61-140). Syn61-140 was overexpressed in E. coli and was purified to apparent homogeneity by taking advantage of the thermosolubility of protein and by using conventional column chromatography techniques. Additional amino acid(Met) is attached at the N-terminus. Alternative Names: PARK 4 protein, SNCA protein, Alpha synuclein protein, PD1 protein, Non-A beta component of AD amyloid protein, PD 1 protein, Synuclein alpha protein, MGC64356 protein, precursor of PARK 1 protein, Non A4 component of amyloid precursor protein, PARK1 protein, NACP protein, Parkinson disease familial 1 protein, PARK4 protein, Non-A4 component of amyloid precursor protein, Non A beta component of AD amyloid protein, Alpha-synuclein isoform NACP140 protein, MGC110988 protein, alpha-Synuclein protein, , MGC127560 protein, Non-A-beta component of alzheimers disease amyloid protein, alphaSYN protein, MGC105443 protein
