MeSH definition : GTP-BINDING PROTEINS that contain three non-identical subunits. They are found associated
with members of the seven transmembrane domain superfamily of G-PROTEIN-COUPLED RECEPTORS.
Upon activation the GTP-BINDING PROTEIN ALPHA SUBUNIT of the complex dissociates leaving
a dimer of a GTP-BINDING PROTEIN BETA SUBUNIT bound to a GTP-BINDING PROTEIN GAMMA
SUBUNIT.;
