Ste5 and Far1 function as prototypical scaffold proteins activating a MAP-kinase cascade and polarizing yeast cells in response to pheromones. Here we show that Pkc1-dependent phosphorylation of conserved serine residues in their RING-H2 domains down-regulates pheromone induced signaling upon mechan...
