Figure 5: HELFIT analyses of LRR domains forming helical dimers-mouse CD14, human RI, and frog LGR4. Left and right figures of each dimer indicate side views and views along the axes of a helix, respectively. In the side views the direction of helix axis is in the direction of the arrows. In the along views the cross signs show that it is in a downward direction and also the dots show that it is in a upward direction. Black circles indicate the first unit.
