Project Description
Identifying the activation mechanism of adhesion G protein-coupled receptors (aGPCRs) has been the main goal of this project. We were able to define a tethered agonist region, establish derived agonistic and antagonistic peptides and showed one possible way to achieve aGPCR activation in vivo and in vitro through an orchestrated sequence including binding of an extracellular interaction partner, mechanical force and tethered agonist-mediated activation of intracellular signaling cascades. We now aim to translate these findings into the characterization of the consequences of the deletion of an orphan aGPCR, the GPR133/ADGRD1 in zebrafish and mice in tissues that are known to respond to or work through mechanical forces, bone and heart.
