FIGURE 3:

Identifying loci in the claudin-19 transmembrane domain important for its interaction with claudin-16. (A) Helical-wheel view of the four TM domains in claudin-19. The positions of alanine insertion are labeled with arrows. (B, C) Effects of alanine insertion into claudin-19 TM domains on the claudin-16 and -19 interaction assayed with the Y2H β-gal reporter gene. The loci with β-gal reporter activity <20% of the wild-type interaction level are labeled with asterisks.
