Figure 5.
Model for oligomerization of the kinase domains of HER3 and inactive HER4 at the plasma membrane. (A) Flexible C-terminal tail/C-lobe interaction creates a possibility for the formation of branched HER3 or inactive HER4 oligomers, resulting in a 2D mesh. (B) Empirical estimates of binding free energy of the HER3/HER4 N-lobe homodimer, calculated using conformations obtained from an all-atom molecular dynamics simulation.
