GTP-bindande proteiner som innehåller tre olika underenheter. De förekommer tillsammans med någon av de sju G-proteinbundna receptorerna i transmembrandomänsuperfamiljen. Vid aktivering frigörs alfa-underenheten från det GTP-bindade proteinkomplexet, varvid återstår en dimer av beta-underenheten och gamma-underenheten.
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.
