Class B1 GPCR activation by an intracellular agonist

Expression and purification of human PTH1R The plasmid encoding human PTH1R (GenBank identifier: U17418.1; residues 27–491) was constructed and purified as previously reported17. The construct was expressed in HEK293 GnTI (N-acetylglucosaminyltransferase I-negative) cells (American Type Culture Collection, CRL-3022) using the BacMam system (Thermo Fisher Scientific), and the cells were grown…
