Human Guanine nucleotide-binding protein G(I);G(S);G(T) subunit beta-1,GNB1 ELI

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.
