G-protein coupled receptors (GPCRs) represent one of the most evolutionarily diverse superfamilies of the human genome. My lab studies all aspects of GPCR structure and function ranging from the atomic-level analysis of ligand-receptor interactions to in vivo studies. Currently we are focused on members of the serotonin (5-hydroxytryptamine; 5-HT) and opioid receptor families and their accessory proteins.
Drug Discovery
We are actively engaged in drug discovery efforts via the shared resources of the National Institute of Mental Health's Psychoactive Drug Screening Program. Our goals are to discover and develop novel small molecule probes for in vitro and in vivo validation of molecular targets for therapeutic drug discovery. We have particular strengths with GPCR and ion-channels and are gradually expanding our capabilities to, eventually, screen the receptorome (the entire complement of receptors in the genome) and kinome (the entire complement of kinases in the genome) in massively parallel screening campaigns (see figure).
