Summary
Our laboratory focuses on understanding and modulating the signaling of class A G protein-coupled receptors (GPCRs). We use a multi-disciplinary approach incorporating peptide and chemical synthesis, NMR spectroscopy, computer-assisted modeling, chemical biology, molecular biology, pharmacology, physiology, and neuroscience to develop novel molecular probes to investigate ligand-receptor interactions and design new tool molecules that can be utilized in developing therapies for obesity, weight management, and pain.
