What some of the names mean

Name Meaning Why? (phenotype)
Ste Sterile Null mutants cannot mate
Gpa1 G-protein alpha subunit Named after function
Cdc Cell division control Cell-cycle arrest at restrictive temperature
Fus Fusion Null mutants defective for cell fusion during mating
Bem Bud emergence Budding defect
Far Factor arrest Null mutants defective for pheromone-imposed cell-cycle arrest
Sst Supersensitive Null mutants are supersensitive to pheromone
Bar Barrier (to α-factor diffusion) Null mutants are supersensitive to α-factor pheromone
Kss1 Kinase-suppressor of Sst2 Multicopy suppressor of sst2 mutant; overproduction of Kss1 inhibits pheromone signaling
Dig Down-regulator of invasive growth Null mutants exhibit constitutive invasion and derepression of Ste12-regulated genes
Ptp Protein tyrosine phosphatase Named after function
Msg5 Multicopy suppressor of GPA1 deletion Overproduction of Mgs5 (a dual-specificity MAPK phosphatase) inhibits pheromone signaling
