MID1, a novel Saccharomyces cerevisiae gene encoding a plasma membrane protein, is required for Ca2+ influx and mating.

By establishing a unique screening method, we have isolated yeast mutants that die only after differentiating into cells with a mating projection, and some of them are also defective in Ca2+ signaling. The mutants were classified into five complementation groups, one of which we studied extensively. This mutation defines a new gene, designated MID1, which encodes an N-glycosylated, integral plasma membrane protein with 548 amino acid residues. The mid1-1 mutant has low Ca2+ uptake activity, loses viability after receiving mating pheromones, and escapes death when incubated with high concentrations of CaCl2. The MID1 gene is nonessential for vegetative growth. The efficiency of mating between MATa mid1-1 and MAT alpha mid1-1 cells is low. These results demonstrate that MID1 is required for Ca2+ influx and mating.[1]
