Membrane Proteins and Cell Signaling
Membranes and membrane proteins participate in some of the most important and interesting cellular processes. Energy transduction, cell signaling, membrane excitability, secretion and immune recognition are examples of a few of the processes mediated by membrane proteins. However, the molecular mechanisms by which lipids and membrane proteins accomplish these tasks are largely unknown. We primarily use EPR spectroscopy and high-resolution NMR to investigate the structure and function of membrane proteins.
Our lab is fundamentally interested in understanding, from a structural and biophysical perspective, the functioning of proteins involved in regulating transcription, particularly those involved in the dysregulation associated with the development of cancer. Structural and functional characterization of the native forms of these proteins and their relevant complexes via NMR spectroscopy, X-ray crystallography, and a variety of other techniques provides a baseline of understanding.
