In cell biochemistry: Targeting synergies in dynamic protein ensembles 
 
Thu, Dec 27, 2018,   12:00 PM to 01:00 PM at Seminar Room 34, 2nd Floor, Main Building

Abstract:

Cellular chemistry relies on an ensemble of  dynamic, transient protein-protein interactions in crowded, compartmentalized cellular environments. Aberrant protein-protein interactions are very often implicated in debilitating or fatal diseases such as diabetes, neurodegenerative diseases, and cancer. Chemical and synthetic biology approaches to target disease states have focused on the function of individual proteins or stable protein complexes, and cannot address emergent behavior stemming from multiple transient interactions. My laboratory uses DNA nanotechnology scaffolds and protein engineering to investigate and target synergies in dynamic protein assemblies in cells (http://proteinacrobaticslab.umn.edu/). The seminar talk will highlight recent advances using these technologies to dissect G protein-coupled receptor signaling and biophysical regulation of cytoskeletal molecular motors.
