Abstract
<jats:p> The mating response of the budding yeast <jats:italic>Saccharomyces cerevisiae</jats:italic> is mediated by a prototypical heterotrimeric GTP-binding protein (G protein) and mitogen-activated protein kinase (MAPK) cascade. Although signal transmission by such pathways has been modeled in detail, postreceptor down-regulation is less well understood. The pheromone-responsive G protein α subunit (Gα) of yeast down-regulates the mating signal, but its targets are unknown. We have found that Gα binds directly to the mating-specific MAPK in yeast cells responding to pheromone. This interaction contributes both to modulation of the mating signal and to the chemotropic response, and it demonstrates direct communication between the top and bottom of a Gα-MAPK pathway. </jats:p>
