Figure 1. Cross-eyed stereo view of the context of the CBM of Couet et al [6] seen in the rat Gi1α protein (PDB code 1CIP; [51]).

The β-hairpin structure of the motif is shown as a cartoon, coloured from blue to red, and the aromatic residues drawn as sticks (Phe189 is blue, Phe191 is cyan, Phe196 is yellow and Phe199 is red). The third strand of the three-stranded sheet to which the motif belongs is also shown in pink. The remainder of the protein is shown as lines and surface, the latter coloured green where contributed by side chains of the aromatic residues.
