Guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit beta-2 is a protein that in humans is encoded by the GNB2 gene.Heterotrimeric guanine nucleotide-binding proteins (G proteins) which integrate signals between receptors and effector proteins are composed of an alpha a beta and a gamma subunit. These subunits are encoded by families of related genes. This gene encodes a beta subunit.
