HMLALPHA2

ALPHA2, YCL067C
Silenced copy of ALPHA2 at HML; homeobox-domain protein that associates with Mcm1p in haploid cells to repress a-specific gene expression and interacts with a1p in diploid cells to repress haploid-specific gene expression
Saccharomyces cerevisiae (S288c)

SST2

GTPase-activating protein SST2, L000002093, YLR452C
GTPase-activating protein for Gpa1p; regulates desensitization to alpha factor pheromone; also required to prevent receptor-independent signaling of the mating pathway; member of the RGS (regulator of G-protein signaling) family

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Autocrine activation of the pheromone response pathway in matalpha2- cells is attenuated by SST2- and ASG7-dependent mechanisms.

Rivers DM, Sprague GF

Yeast mat alpha2 mutants express both mating pheromones and both mating pheromone receptors. They show modest signaling in the pheromone response pathway, as revealed by increased levels of FUS1 transcript, yet are resistant to pheromone treatment. Together, these phenotypes suggest that alpha2- cells undergo autocrine activation of the pheromone response pathway, which is subsequently attenuated. We constructed a regulatable version ...
