heterotrimeric G-protein complexImported
Any of a family of heterotrimeric GTP-binding and hydrolyzing proteins - they belong to a superfamily of GTPases that includes monomeric proteins such as EF-Tu and RAS. Heterotrimeric G-proteins consist of three subunits - the alpha subunit contains the guanine nucleotide binding site and possesses GTPase activity - the beta and gamma subunits are tightly associated and function as a beta-gamma heterodimer - extrinsic plasma membrane proteins (cytoplasmic face) that function as a complex to transduce signals from G-protein coupled receptors to an effector protein.
