CC   -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are involved
CC       as a modulator or transducer in various transmembrane signaling
CC       systems. The beta and gamma chains are required for the GTPase
CC       activity, for replacement of GDP by GTP, and for G protein-effector
CC       interaction.
CC   -!- SUBUNIT: G proteins are composed of 3 units, alpha, beta and gamma.
CC   -!- SIMILARITY: Belongs to the WD repeat G protein beta family.
CC       {ECO:0000305}.
