Extended Data Fig. 6: Cryo-EM density fit of the outward-facing FLVCR2 model.
From: Structural and molecular basis of choline uptake into the brain by FLVCR2

Cryo-EM densities (semi-transparent surface) are superimposed on the structural elements of MmFLVCR2 including TM helices 1–12 and bound choline. All elements are shown in stick representation and coloured as in Fig. 2.
