Project description
High-resolution analysis of protein aggregation
Under pathological situations proteins may misfold, forming aggregates that disrupt cellular functions and cause disease. The aggregation of alpha-synuclein (αSyn) is a hallmark of Parkinson’s disease and its deposition into Lewy bodies leads to neuronal dysfunction. Emerging evidence indicates that αSyn undergoes liquid-liquid phase separation, a reversible process where the protein solution separates into dense and dilute phases. High concentrations in the dense phase promote αSyn aggregation into amyloid fibrils. With the support of the Marie Skłodowska-Curie Actions programme, the IDP Assembly project aims to develop a novel method for high-resolution analysis of αSyn aggregation, paving the way for novel interventions.
Objective
Protein aggregation hallmarks several neurodegenerative diseases, including Alzheimer's and Parkinson's. In Parkinson's, aggregation of the intrinsically disordered protein (IDP) alpha-synuclein (Syn) leads to its intracellular deposition into Lewy bodies, which causes neuronal dysfunction. Recently it was discovered that Syn can undergo liquid-liquid phase separation (LLPS), whereby a protein solution spontaneously separates into a dense and a dilute phase. This process is initially reversible, but the high concentrations of the dense phase strongly favor the aggregation of Syn into amyloid fibrils. Structural characterization of the transient Syn conformations during LLPS and amyloid formation is therefore crucial for understanding the disease pathology on the molecular level. This project aims to develop a novel experimental concept for the high-resolution conformational analysis of Syn assembly and aggregation using scanning mutagenesis combined with cutting-edge high-throughput biophysical techniques and computational analysis. The core idea is to apply multiple biophysical assays to quantify the effects of hundreds of Syn mutations on the kinetics and thermodynamics of LLPS and amyloid formation. The resulting multidimensional experimental datasets will be processed within the phi-value analysis framework originally derived for protein folding and combined with molecular dynamics simulations. The integrated methodology will allow gaining important structural and mechanistic insights into the early-aggregation events of Syn at a single amino acid level of resolution. The project includes extensive training to enhance my scientific skills in modern experimental and computational methods. The proposed strategy is widely applicable to other IDP systems that can undergo LLPS and aggregation and paves the way for the design of rational and precisely tailored intervention strategies against the diseases associated with these phenomena.
