Project B06 – Dynamic modulation of adhesion GPCR function through complex formation

The activity profile and signaling capacity of adhesion GPCRs (aGPCR) may be modulated through crosstalk between different cell surface molecules and may be triggered and/or modulated by mechanical input. We will identify ligand-receptor complexes of aGPCRs through in vitro and in vivo orthogonal labeling and photo-crosslinking as well as intermolecular FRET approaches, respectively. In a further tier of experiments, we will investigate if putative interactors affect aGPCR signaling in a mechano-dependent fashion, test if mechanical stimuli serve as a switch for aGPCR dimerization/oligomerization and investigate how the viscoelastic properties of these interactions correlate with aGPCR activity.
