Supplementary Figure 2: Crystal structure of the plectin-calmodulin complex and selected best protein complex models obtained after the final HADDOCK docking step.

(a) Selected model after re-calculation using the correct distance restraints between residues. This model displayed the best HADDOCK score and XL score. (b) Selected model after re-calculation using the correct distance restraints between specific atoms. This model displayed the best combination of HADDOCK score and XL score. (c) Selected model as presented in our protocol, calculated using the erroneously short distance restraints. (d) Crystal structure of the plectin-calmodulin complex: PDB ID 4Q57. (a-d) The calmodulin chain is colored red
