Research

My research goal is to uncover the molecular principles of how Hsp90/Hsp70 chaperone machinery regulates the activity of the glucocorticoid receptor (GR). With a joint effort with Chari Noddings, we are using a hybrid approach combining cryo-EM and Rosetta structural modeling tools to determine atomic structures of GR-bound chaperone machinery in two critical states on the chaperone-assisted protein maturation pathway –– the client-loading and client-maturation complexes. Furthermore, we are applying a combination of in vitro biochemical and biophysical approaches to elucidate how Hsp90’s two events of ATP hydrolysis are coupled to GR’s conformational remodeling and to the assembly/disassembly of the Hsp90/Hsp70 chaperone machinery. It's been extremely fun with quite a lot of surprises and excitement so far.
