Webmodifications of alpha-synuclein, including nitration and hyper-phosphorylation at Ser129, are known to increase its tendency to aggregate and misfold, as well as the presence of dopamine adducts, which could partly explain the selective susceptibility to dopaminergic neurons to the neurodegenerative process [13]. WebMay 1, 2013 · Alpha-synuclein (α-synuclein) is a small, acidic protein containing 140 amino acids, highly expressed in the brain and primarily localized in the presynaptic terminals. It is found in high concentrations in Lewy Bodies, proteinaceous aggregates that constitute a typical histopathologic hallmark of Parkinson's disease.
