In Silico Stability Analysis and Phosphorylation Induced Structural Simulation of Alpha-synuclein in Parkinson’s disease
Abstract: Alpha-synuclein (α-syn) is the major component of pathologic inclusions that characterizes neurodegenerative disorders such as Parkinson’s disease (PD), dementia with Lewy body disease, and multiple system atrophy. Mutations and phosphorylation of α-syn causes familial PD. Phosphorylation of α-syn at TYR125 and SER129 plays an important role in PD and enhances its partial digestion by calpains leading to its aggregation; however, the exact mechanism is unknown. The present study uses in …
