We generated a plasmid library containing randomly mutagenized Ste4 ORFs, followed by phenotypic selection of ste4p mutants by altered alpha pheromone response in yeast cells. Subsequently, we analyzed mutant ste4-10 which has a replacement of the almost universally conserved leucine 132 by phenylalanine. This residue lies in the first blade of the beta propeller structure proposed by crystallographic analysis. By overexpression experiments we found that mutant ste4p subunit triggers the mating pathway at wild type levels in both wild type and receptorless strains. When expressed in a ste4 background, however, the mutant G protein is activated inefficiently by mating pheromone in both a and alpha cells. The mutant ste4-10p was tested in the two-hybrid system and found to be defective in its interaction with the Gpa1p, but has a normal association with the C-termini end of the Ste2p receptor. These observations strongly suggest that the Leu-132 of the Ste4p subunit is essential for efficient activation of the G protein by the pheromone-stimulated receptor and that this domain could be an important point for physical interaction between the Gbeta and the Galpha subunits."xsd:string |
