Description
The GTP binding regulatory proteins (G proteins) consist of three subunits: α, β, and γ. These heterotrimeric proteins function at membranes to relay signals from cell surface receptors to intracellular effectors. The α subunit is unique for each G protein and contains the site of GTP binding and hydrolysis, as well as sites for receptor and effector interactions. The βγ subunit complex interacts directly with receptors and the α subunit. The Gα protein transducin (Gαt) contains 350 amino acids and has been extensively studied as a model for G protein function. Gαt requires GTP in order to bind to its effectors. In the process of effector-Gαt binding, GTP is hydrolyzed and the βγ subunits are displaced. The free Gαt-GDP then reassociates with the βγ subunits and re-loads GTP to repeat the cycle.
