Fig. 3: Lipids accommodated in the pockets between paddle domains.

a The cone-shaped pocket formed by three adjacent paddle domains (blue, purple, and cyan) in the membrane (indicated by dashed lines). Within the pocket, there is a bulky lipid density (gray mesh). The kink point in TM3, G160, is shown as black balls. b Zoomed-in views of the lipid density (as boxed in a) in the pocket. R120 and Q100 seem to directly interact with the lipid headgroup.
