Gene Information

human ... GNB3(2784)

General description

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. Beta subunits are important regulators of alpha subunits, as well as of certain signal transduction receptors and effectors. A single-nucleotide polymorphism (C825T) in this gene is associated with essential hypertension and obesity. This polymorphism is also associated with the occurrence of the splice variant GNB3-s, which appears to have increased activity. GNB3-s is an example of alternative splicing caused by a nucleotide change outside of the splice donor and acceptor sites. Additional splice variants may exist for this gene, but they have not been fully described. (provided by RefSeq)
The guanine nucleotide-binding proteins β-3 subunit (GNB3) codes for the β subunit of G protein heterotrimer (Gαβγ). This protein is composed of seven highly conserved repeating units (∼40 amino acid motifs) usually ending with Trp-Asp (WD). GNB3 is located on human chromosome 12p13.31.


GNB3 (AAH02454, 1 a.a. ~ 340 a.a) full-length recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.


Biochem/physiol Actions

The guanine nucleotide-binding proteins β-3 subunit (GNB3) participates in signal transduction pathways. It is associated with favorable antidepressant response. GNB3 is involved in G protein-coupled receptor signaling. Biallelic mutations in GNB3 result in autosomal-recessive Congenital stationary night blindness.
