Saccharomyces cerevisiae α factor pheromone arrest growth of cells of the a mating type (MAT a) at the G1 phase of the cell cycle. When treatment of MAT a cells with α factor was carried out in the presence of anticalmodulin drugs, trifluoperazine or chlorpromazine, the extent of cell growth arrest induced by α factor was reduced or even became undetectable. These results lend support to the hypothesis that calmodulin plays a role as mediator in the action of α factor on MAT a cells.
