Compositional Bias
238..261; Basic and acidic residues; 353..369; Polar residues
Domain (CC)
Histamine activates the receptor by forming hydrogen bonds with transmembrane domains 3 and 6, squashing the ligand-binding pocket on the extracellular side and opening the cavity for G-protein engagement on the intracellular side.
