Guanine nucleotide-binding protein subunit beta

UniProtKB accession:  P18851

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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.
