Regulation of the G-protein-coupled alpha-factor pheromone receptor by phosphorylation.


The alpha-factor pheromone receptor activates a G protein signaling cascade that stimulates MATa yeast cells to undergo conjugation. The cytoplasmic C terminus of the receptor is not necessary for G protein activation but instead acts as a regulatory domain that promotes adaptation to alpha-factor. The role of phosphorylation in regulating the alpha-factor… (More)
