While the basolateral membrane is in contact with the interstitial tissue, the apical membrane is in contact with the external environment and thus also acts as a barrier to prevent potential pathogens or toxic compounds from reaching the bloodstream. Finding small-molecule ligands in cryo-EM protein structures is never a sure thing (at least it isn't in 2022), so being able to pick out the lumacaftor density and work out its interactions with the protein is quite a feat.
