8.A.92.1.2
G-protein complex with subunits α, β, γ1 and γ2. Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction (Mudgil et al. 2009).
