Molecular dissection of amyloid disaggregation by human HSP70

The deposition of highly ordered fibrillar-type aggregates into inclusion bodies is a hallmark of neurodegenerative diseases such as Parkinson’s disease. The high stability of such amyloid fibril aggregates makes them challenging substrates for the cellular protein quality-control machinery1,2. However, the human HSP70 chaperone and its co-chaperones DNAJB1 and HSP110 can dissolve preformed fibrils of the Parkinson’s disease-linked presynaptic...
