Research interests

    The main research interest of the laboratory has always been focused on the study of structural and functional properties of seven-transmembrane receptors (GPCRs) and their coupled heterotrimeric G proteins. Though the years several aspects of GPCR/G protein biology have been investigated, ranging from post-translational modifications to partitioning in membrane domains, receptor dimerization, and signaling. Currently, we study the oxytocin GPCR in relationship to synapse formation in the hippocampal neurons and the role of the heterotrimeric G15 protein in pancreatic cancer. Our experimental models are primary neuronal cultures or cell lines wild type or transfected with various cDNAs. We combine multiple techniques, such as biochemistry, cell and molecular biology, high-resolution imaging analysis using immunofluorescence and confocal biology, and fluorescence resonance energy transfer (FRET) proximity assay to detect protein-protein interactions in living cells.
