Molecular pharmacology of G protein-coupled receptors in the Bräuner-Osborne group
The Bräuner-Osborne group focus on pharmacological and physiological characterization of G protein-coupled receptors bridging from development of novel pharmacological tool compounds by integration of pharmacology, medicinal chemistry and computer modeling to understand the physiological role and therapeutic prospects of the receptors.
A main focus of my group is development of ligands with novel pharmacological profiles at G protein-coupled receptors. Another interest is to understand ligand-receptor interactions, subtype selectivity, activation mechanisms and signaling pathways at the molecular/mechanistic level.
Another focus area is orphan receptors for which the endogenous ligands remains to be identified. We have identified putative endogenous and/or surrogate ligands for a range of orphan receptors including GPRC6A, GPR139, GPR15 and GPR132.
Finally, the group work with clinicians and geneticists with the aim of understand molecular mechanisms of disease and improve treatments via personalized medicine.
