Rabbit anti-Human GNB3 Polyclonal Antibody

Uniprot Id

P16520

Target Species

Human

Target Name

GNB3

Target Full Name

Guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit beta-3

Target Function

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.

Target Involvement

Night blindness, congenital stationary, 1H (CSNB1H)

Target Protein Families

WD repeat G protein beta family

Target Synonyms

G protein beta 3 subunit; GBB3_HUMAN; GNB3; GNB3 guanine nucleotide binding protein (G protein), beta polypeptide 3; GTP binding regulatory protein beta 3 chain; Guanine nucleotide binding protein (G protein) beta polypeptide 3; Guanine nucleotide binding protein G; Guanine nucleotide binding protein G(I)/G(S)/G(T) beta subunit 3; Guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit beta-3; Hypertension associated protein; IG; SG; Transducin beta chain 3; Tsubunit beta 3

Target Background

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 which belongs to the WD repeat G protein beta family. 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. Alternative splicing results in multiple transcript variants. Additional alternatively spliced transcript variants of this gene have been described, but their full-length nature is not known.
