Biography

Research

The Wedekind lab investigates the mechanisms of action of non-protein-coding (nc)RNAs. We are interested especially in the elegant, three-dimensional architectures of these RNAs, and how they bind to specific small molecules or peptides, leading to conformations that alter biological function. Model systems include: (i) metabolite-sensing riboswitches that regulate protein translation, and (ii) the application of lab-evolved proteins to target HIV-1 RNA. This work is relevant to the development of new antibiotics and anti-retroviral therapies. This work is funded by NIH/NIGMS grants R01 GM063162 and R01 GM123864.

Our lab employs a variety of biochemical, biophysical, and structural approaches, such as X-ray crystallography. We greatly acknowledge NIH/NCRR award S10 RR026501 for supporting this instrumentation. For access or further information see: https://www.urmc.rochester.edu/structural-biology-biophysics.aspx
