From: Unraveling the molecular architecture of a G protein-coupled receptor/β-arrestin/Erk module complex

Complete complex model. The model can accommodate the presence of Clathrin and the SH2 domain of c-Src.
The color code for the main complex is the same as in Fig. 3. Possible geometry of the complex including the β-arrestin/Erk1 module, including SH2 domain of c-Src (in orange) and clathrin (in marine blue).
