Research Description

The University of Wisconsin Transmembrane Protein Center (TMPC) will function as a collaborative project within the PSI:Biology Network. The collective experience of our already-assembled research team suggests that application of many techniques will be needed to expand the chances for success with the broad range of membrane proteins expected from participation in the PSI:Biology Network. This project is well poised to provide the expertise and leadership needed to successfully advance the goals of the PSI:Biology Network, including outreach to new participants in this large-scale endeavor. We have experience in the expression, production, and characterization of membrane proteins, proven ability to solve structures of complicated membrane proteins, and a strong track record of studying the interactions of membrane proteins with their protein partners and biological ligands. We also have strong grounding in the use of bioinformatics and bioanalytical techniques. Every participant brings unique experience with the function of membrane proteins, including assay development, preparation methods, or studies with either purified proteins and living organisms. This emphasis on merging the production of membrane proteins for structure determination with the power of functional characterizations is the central philosophy of TMPC. Our primary goal is determining a founding structure for unique target classes. Our second goal is to establish an efficient membrane protein production pipeline so that increases in throughput may be progressively obtained. We expect to improve our ability to create protein variants, to refine screening based on functional and biophysical characterizations, and to improve sorting between multiple expression pathways to find the best way produce a protein of interest. Emphasis on small-scale purification screening, and further integration of automation into our efforts will increase efficiency. Expanded options for crystallization screening, access to synchrotrons, and improvements in software used to solve structures will also contribute to the increased throughput necessary to achieve PSI:Biology goals.
