Project A06 – Enzymology of autoproteolysis and signaling function of the GAIN domain in adhesion GPCRs

Signal transduction via the GAIN (GPCR autoproteolysis inducing) domain is a unique property of adhesion G protein-coupled receptors (aGPCRs). We will systematically investigate the role of active site residues of the GAIN autoprotease on GPCR proteolysis site (GPS) cleavage by expression of the isolated domain, entire ectodomain and full-length aGPCR. These experiments will characterize the influence and role of active site residues, and the complex formed with other extracellular folds and the 7TM part on GAIN autoproteolytic activity. We will determine crystal structures of ectodomains in the pre-cleavage and post-cleavage states. Furthermore, we will investigate how the structure and dynamics of the GAIN domain influences the activation of aGPCRs by release of the Stachel peptide acting as a tethered agonist.
