What is the activation mode of GLP1R?
The binding mode of GLP-1R and ligand is mainly the well-known "two-domain model". The C-terminus of the ligand first binds to the extracellular domain of the GLP-1R, which changes the spatial conformation of the GLP-1R and exposes the binding site of the core domain, and then the N-terminal end of the ligand binds to the core domain of the GLP-1R, which activates the GLP-1R. In general, the main role of the extracellular domain of the GLP-1R is to recognize specific ligands, while the core domain plays an important role in signal specificity transmission.
