Current research interest

Quality-control proteins work by avoiding and reverting protein misfolding and aggregation. Although extensive studies have been made to describe the way these potent machines perform their function, it is still unclear how the combination of different ATP states relates to the proteins’ conformation and their mechanism of action. Therefore, my current interests are to elucidate the mechanism by which AAA+ remodeling machines perform their function of rescuing damaged proteins from aggregated state. I will focus on Hsp104, which is a potent unfoldase and disaggregase chaperone, and its interaction with the general folding factor Hsp70. I will use structural techniques (X-ray crystallography and EM) and single-molecule biochemistry to get a better mechanistic understanding of the 104-70 interplay and its role in protein (mis)folding diseases.
