== Function ==
[https://www.uniprot.org/uniprot/GBG2_BOVIN GBG2_BOVIN] 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.

== Publication Abstract from PubMed ==
The beta(1)-adrenergic receptor (beta(1)-AR) can activate two families of G proteins. When coupled to Gs, beta(1)-AR increases cardiac output, and coupling to Gi leads to decreased responsiveness in myocardial infarction. By comparative structural analysis of turkey beta(1)-AR complexed with either Gi or Gs, we investigate how a single G-protein-coupled receptor simultaneously signals through two G proteins. We find that, although the critical receptor-interacting C-terminal alpha5-helices on Galpha(i) and Galpha(s) interact similarly with beta(1)-AR, the overall interacting modes between beta(1)-AR and G proteins vary substantially. Functional studies reveal the importance of the differing interactions and provide evidence that the activation efficacy of G proteins by beta(1)-AR is determined by the entire three-dimensional interaction surface, including intracellular loops 2 and 4 (ICL2 and ICL4).
