  • Beschreibung: The adhesion G protein–coupled receptor (aGPCR) GPR126/ADGRG6 plays an importantrole in several physiological functions, such as myelination or peripheral nerve repair. Thisrenders the receptor an attractive pharmacological target. GPR126 is a mechano-sensorthat translates the binding of extracellular matrix (ECM) molecules to its N terminus into ametabotropic intracellular signal. To date, the structural requirements and the character ofthe forces needed for this ECM-mediated receptor activation are largely unknown. In thisstudy, we provide this information by combining classic second-messenger detection withsingle-cell atomic force microscopy. We established a monoclonal antibody targeting the Nterminus to stimulate GPR126 and compared it to the activation through its known ECMligands, collagen IV and laminin 211. As each ligand uses a distinct mode of action, the Nterminus can be regarded as an allosteric module that can fine-tune receptor activation in acontext-specific manner.
