The Granier Lab aims at characterizing the molecular and structural mechanisms of GPCRs and PAQRs function. GPCRs and PAQRs present a seven transmembrane domain (7TM) which acts as a receptor and a transducer of extracellular signals within the cell to regulate a wide variety of physiological function.As such, they are the subject of intense studies both in academic labs and in industry with important drug discovery programs. Despite recents advance in the field, there is still an important lack of knowledge of 7TM signalling mechanisms and pharmacology. This is mainly due to the challenges associated with the characterization of membrane protein structure and function.

To fill this gap of knowledge, we are developing an innovative integrated strategy combining state-of-the-art molecular and structural pharmacology approaches including:


1) Molecular analyses of transmembrane signalling network using resonance energy transfer measurement in living cells and proteomic analyses
2) Structural analyses of receptors and signalling complexes using biochemistry, fluorescence, NMR spectroscopy and X-ray crystallography.
