My laboratory focuses on the structural and functional characterization of signaling peptides and proteins known to function without a well-defined folded structure. These molecules typically do not crystallize, but can be characterized by NMR spectroscopy and computational approaches. We are discovering that biological function is often associated with a change in both structure and flexibility. Most of our research involves NMR spectroscopy, computational biology and molecular biology. On-going projects focus on: neuropeptides and their precursor proteins; a protein inhibitor of yeast proteinase A; MARCKS, the major hippocampal substrate for PKC phosphorylation; mutacin 1140, a potent antibiotic; neuropeptide agonists and antagonists of melanocortin receptors. |
