a, Stereo figure of the dimer interface. Representation of the interface residues (ball-and-stick) on a schematic secondary structure. The figure shows the plus face of subunit A (light yellow, orange interface residues) and the minus face of subunit B (light blue, pink interface side chains). b, Dimer interface interactions. Note that owing to the low conservation of these interfaces (Fig. 1) the actual interactions will not be conserved in any pentameric LGIC interface, but that in all receptors these topological regions are likely to form the interface.
