Functional Description
Implicated in the pheromone A- and alpha-factor response pathway. The beta and gamma chains of the putative yeast mating response pathway G protein play a positive role in initiation of the mating response.
Sequence Annotation
Modified residue: 107 107 Cysteine methyl ester.
Protein Length
110 AA.
