Which shows a receptor with the N-terminal outside the cell, seven transmembrane spanning domains, 3 exoloops, 4 cytoloops and a C terminal inside the cell.
However, it is actually more compact with the seven transmembrane spanning domains forming a tight core.
Lower part = T4-lysozyme in place of cyto 3 Small green molecules = cholesterol; can just make out bound ligand in pocket
