TheSaccharomyces cerevisiaeG protein βγ dimer, Ste4p/Ste18p, acts downstream of theasubunit, Gpalp, to activate the pheromone response pathway and therefore must interact with a downstream effector. Synthetic sterile mutants that exacerbate the phenotype ofste4-tsmutations were isolated to identify proteins that functionally interact with Ste4p. The identification of astel8mutant indicated that this screen could identify proteins that interact directly with Ste4p. The other mutations were inSTE5and theSTE20kinase gene, which act near Ste4p in the pathway, and a new gene calledSTE21. ste20null mutants showed residual mating, suggesting that another kinase may provide some function. Overexpression of Ste5p under galactose control activated the pheromone response pathway. This activation was dependent on Ste4p and Ste18p and partially dependent on Ste20p. These results cannot be explained by the linear pathway of Ste4p → Ste20p → Ste5p. Overexpression of Cdc42p resulted in a slight increase in pheromone induction of a reporter gene, and overexpression of activated forms of Cdc42p resulted in a further twofold increase. Mutations in pheromone response pathway components did not suppress the lethality associated with the activatedCDC42mutations, suggesting that this effect is independent of the pheromone response pathway.
