Graphical representation of the Caver3.0 results. The first and the second tunnels are represented in blue and green, respectively. The three phosphorylated serine residues are always depicted in magenta as spatial references. In the cases of Ser-264-α-P and Ser-271-α-P, in which the tunnels have a common pathway, only one color is used to depict the common part.
