The dimer interface of IL-6R showing the region of interaction by red, green, blue, purple, and cyan areas representing interdimeric distances (58) of less than 5, 4, 3, 2, and 1 Å, respectively. The view is rotated 180° relative to the view in Fig. 1; the crystal twofold axis is vertical, and the membrane is horizontal below the molecule.
