OrganismSaccharomyces cerevisiae (replicative)
Aging PhenotypeNo effect on life-span
Allele TypeDeletion
DescriptionDeletion has no effect on mean or maximum life span (Kennedy et al., 1995).
Gene FunctionG-protein beta-subunit. Involved in signal transduction by pheromones. Required for response to mating pheromone (Bardwell, et al., 1994).
Other PhenotypesMutants are sterile (Hartwell, 1980).
