Rabbit anti-Human GNB5 Polyclonal Antibody

Uniprot Id

O14775

Target Species

Human

Target Name

GNB5

Target Full Name

Guanine nucleotide-binding protein subunit beta-5

Target Function

Enhances GTPase-activating protein (GAP) activity of regulator of G protein signaling (RGS) proteins, hence involved in the termination of the signaling initiated by the G protein coupled receptors (GPCRs) by accelerating the GTP hydrolysis on the G-alpha subunits, thereby promoting their inactivation (Probable). Increases RGS9 GTPase-activating protein (GAP) activity, hence contributes to the deactivation of G protein signaling initiated by D(2) dopamine receptors. May play an important role in neuronal signaling, including in the parasympathetic, but not sympathetic, control of heart rate.

Target Involvement

Intellectual developmental disorder with cardiac arrhythmia (IDDCA); Language delay and attention deficit-hyperactivity disorder/cognitive impairment with or without cardiac arrhythmia (LADCI)

Target Subcellular Location

Membrane.

Target Protein Families

WD repeat G protein beta family

Target Tissue Specificity

Widely expressed.

Target Research Area

Signal Transduction

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. Beta subunits are important regulators of alpha subunits, as well as of certain signal transduction receptors and effectors. Alternatively spliced transcript variants encoding different isoforms exist.
