  1. Shown are the computed minimal intervention sets to activate ERK and deactivate PI3K in presence of ErbB1, ErbB2, and ErbB3 (see Figure 2B). “1” means constitutive activation whereas “0” indicates a required deactivation. Interventions for species with fixed values (i.e., ErbB1, ErbB2, ErbB3) and the target species ERK and PI3K have not been considered.
