There are three native <scene name='72/721545/Disulfides/2'>disulfide bonds</scene> in the extracellular region.<ref name= "Chrencik"/> One of these bonds constrains the N terminal helix to extracellular loop 2. The <scene name='72/721545/N-terminus/2'>N-terminus</scene> functions like a cap on the extracellular side of the protein, packing tightly against ECL1 and ECL2. It also provides <scene name='72/721545/34_39_40/3'>polar amino acids</scene> that interact with the ligand when bound. | ||
