Mutations in Hsap\SNCA (based on a structure-based design rationale) which increase neurotoxicity, show reduced fibril and β-structure formation and increased soluble oligomers in vitro.
The expression of Hsap\SNCAA56P.Scer\UAS.cKa under the control of Scer\GAL4Ddc.PL results in significant decreases in adult lifespan, as compared to controls.
