Fig. 2. Structure of sErbB4. (A) Ribbon diagram of sErbB4.
Domains I, II, III, and IV are colored blue, green, yellow, and
red, respectively. The N and C termini are indicated by the
letters N and C. (B) Surface representation of sErbB4. The
intramolecular contact between domains II and IV is boxed. (C)
Domain II/IV contact in ligand-binding sErbBs. Residues at the
tether between domains II and IV of sErbB4 are shown in green
(domain II) and red (domain IV). The equivalent residues from
tethered sErbB1 and sErbB3 are shown in gray and white,
respectively (3, 6). The buried surface areas and the surface
complementarity coefficients for each tether are indicated in
the legend.
