| Method | Details | Software |
| distance geometry/simmulated annealing | The structures are based on a total of 866 intramonomer and 46 intermonomer NOE-derived distance constraints and 34 TALOS-derived dihedral angle restraints. The monomer structure was calculated first and then the dimer was built from random monomer starting orientations. | VNMR |
