Definition: Heterotrimeric GTP-binding protein subunits that tightly associate with GTP-BINDING PROTEIN BETA SUBUNITS. A dimer of beta and gamma subunits is formed when the GTP-BINDING PROTEIN ALPHA SUBUNIT dissociates from the GTP-binding protein heterotrimeric complex. The beta-gamma dimer can play an important role in signal transduction by interacting with a variety of second messengers.
Other names gamma Subunit, G-Protein; Subunit, G-Protein gamma; GTP Binding Protein gamma Subunits; GTP Binding Protein gamma Subunit; G Protein gamma Subunit; GTP-Binding Protein gamma Subunit; G-Protein gamma Subunit
