CV Dr. Peter Schmidt

Research Area

Since 2006, I have been investigating the Y1 and Y2 receptors as member of the Daniel Huster lab. I have established the recombinant expression of the receptor proteins using E. coli and we are also developing cell-free expression systems for efficient isotope labeling for NMR studies. My expertise is the functional folding of the Y receptors in different phospholipid and detergent environments. Finally, I study the interaction of the Y receptors in interaction with their natural ligand NPY using solid-state as well as solution NMR techniques.
