Protein
Guanine nucleotide-binding protein subunit beta
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Implicated in the 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. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.
Similarity
Belongs to the WD repeat G protein beta family.
