Accessory monomer expression levels can be used to transform a switch-on function to a switch-off function. For each panel, a network schematic is shown on the left, the protein expression levels for each hypothetical cell type are shown in the middle, and the input-output computations for each cell type are shown on the right. All input-output functions in (A)–(D) are displayed in unitless concentrations (seeSTAR Methods).
