    Cells use a network of mitogen-activated protein kinases (MAPKs) to coordinate responses to diverse extracellular signals. Here, we examine the role of docking interactions in determining connectivity of the yeast MAPKs Fus3 and Kss1. These closely related kinases are activated by the common upstream MAPK kinase Ste7 yet generate distinct output responses, mating and filamentous growth, respectively. We find that docking interactions are necessary for communication with the kinases and that they can encode subtle differences in pathway-specific input and output. The cell cycle arrest mediator Far1, a mating-specific substrate, has a docking motif that selectively binds Fus3. In contrast, the shared partner Ste7 has a promiscuous motif that binds both Fus3 and Kss1. Structural analysis reveals that Fus3 interacts with specific and promiscuous peptides in conformationally distinct modes. Induced fit recognition may allow docking peptides to achieve discrimination by exploiting subtle differences in kinase flexibility.
