The interaction of alpha-synuclein with membranes and its implication in parkinsońs disease: A literature review

Abstract

Alpha-synuclein belongs to the class of intrinsically disordered proteins lacking a well-folded structure under physiological conditions. The conversion of alpha-synuclein from a soluble monomer to an insoluble fibril may underlie the neurodegeneration associated with Parkinson's disease (PD). Although the exact mechanism of alpha-synuclein toxicity is still unknown, it has been proposed that alpha-synuclein disturbs membrane structure, leading to increased membrane permeability and eventual cell death. This review highlights the significant role played by fluorescence techniques in unraveling the nature of interactions between alpha-synuclein and membranes and its implications in PD.
