Guanine Nucleotide-Binding Protein G(I)/G(S)/G(T) Subunit Beta-2

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit beta-2 (340 aa, ~37 kDa) is encoded by the human GNB2 gene. This protein is involved in transmembrane signaling through the regulation of G protein alpha subunits and the integration of signals between receptors and effector proteins.

**Synonyms:** - G Protein Subunit Beta-2 - G Protein, Beta-2 Subunit - GNB2 - Guanine Nucleotide Binding Protein Beta 2 - Guanine Nucleotide-Binding Protein G(I)/G(S)/G(T) Beta Subunit 2 - Signal-Transducing Guanine Nucleotide-Binding Regulatory Protein Beta Subunit - Transducin Beta Chain 2
