Masters Theses

Molecular chaperones play a key role in maintaining a healthy cellular proteome by performing protein quality control. Heat shock protein 70s (Hsp70s) are a diverse class of evolutionarily conserved chaperones that interact with short hydrophobic sequences presented in unfolded proteins, promoting productive folding, and preventing proteins from aggregation. Most of the extensive research on chaperone examines mechanism, substrate promiscuity, and engagement with many co-chaperones. Only recently were chaperones recognized to be frequent targets of post-translational modifications (PTMs). Despite the recent rise in PTMs identified, the impact of these modifications on chaperone function, whether singular or in concert with other modifications, …
