Cholesterol interaction scores for every residue, rendered on the membrane-facing surface (A) and a snake plot (B). Blue indicates no interaction with cholesterol, red indicates a high probability for cholesterol interaction. Inset of (A) shows the middle row from Fig. 1, to orient the viewer and to facilitate comparison to cholesterol densities. The highest-ranked locations are referred to in the text as h56i and h6o, and appear in the far right image. In (B), the residues of h6o are indicated as diamonds, and h56i as squares.
