And the TMD is responsible for further interaction with the N-terminus of the ligand, which triggers receptor activation (Graaf et al., 2016)
Class B GPCRs typically bind their peptide ligands through a mechanism known as the two-domain model, in which ECD binds to the C-terminal helix of GLP-1, and the transmembrane domain (TMD) binds to the N-terminal region of GLP-1 (3, 4, 5)
