Like other GPCRs, it has a <scene name='72/721538/7tm_labeled_helicies/3'>7 trans-membrane </scene> helical domain (shown in blue) and a globular N-terminus <scene name='72/721538/Ecd/2'>extracellular domain</scene> (shown in magenta). As its name suggests, the 7tm is made up of alpha helices that pass through the membrane seven times. The extracellular domain has an α-β-β structure that consists of two antiparallel β-sheets and a N-terminal α-helix<ref>PMID:26227798</ref>. | ||
