Mechanisms Overwhelming Protein and Organelle Quality Control in Parkinson’s Disease

2020-Present

Parkinson’s disease, at the molecular level, results from the failure of cellular quality control (QC) mechanisms, and finding ways to maintain (or augment) QC capacity will provide new therapeutic strategies for PD and possibly other neurodegenerative disorders. Using powerful molecular visualization and discovery tools in disease-relevant cells, we will elucidate how individual types of protein aggregates linked with PD strains (including patient-derived aggregates) alter cellular pathways, including effects on cell survival and function. We will also use genetic approaches to understand what cellular proteins promote the processing of PD-related aggregates.

Q-DOAS: A Proximity Quenching Assay for Real-Time Detection of Early Protein Aggregation Events

Accurate measurement of protein aggregation is essential for studying neurodegenerative diseases. The standard ThT assay reports on amyloid formation but is blind to early oligomers and is prone to interference. We describe Q-DOAS, a plate-reader assay that quantifies protein self-assembly in real time via proximity-quenching of a single, site-specifically conjugated...
