  • FunctionGuanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.
  • Sequence similaritiesBelongs to the WD repeat G protein beta family.
    Contains 7 WD repeats.
  • Cellular localizationCytoplasm > perinuclear region.
