Figure 2. The structure of the rhodopsin-arrestin complex.
a, The structure of the rhodopsin-arrestin complex in four orientations. The relative dimensions of rhodopsin and arrestin are shown in the intracellular view. TM1-TM7 indicates rhodopsin transmembrane helices 1–7; H8 is intracellular Helix 8.
b, An overall view of the rhodopsin-arrestin complex shown with transparent solid surface. T4 Lysozyme (T4L) is omitted from this view.
c, Crystal packing diagram of the rhodopsin-arrestin complex with T4L as yellow ribbon model.
