Stereo view of the PTPRG^CA·CNTN4^Ig1-4 interface.
This view is in the same orientation as the right view in Fig.
5. Residues are shown as ball-and-sticks with transparent gray
spheres for those involved in van der Waals contacts. Dashed
lines indicate potential hydrogen bonds and salt bridges.
Residues from CNTN4^Ig2, CNTN4^Ig3, and PTPRG^CA are colored
green, gold, and magenta, respectively.
