Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human RGS4 protein.
Background
Regulators of G protein signaling (RGS) are a family of about 40 proteins that determine the signaling amplitude and duration of G protein-coupled receptor signaling via modulation of the GTPase activity of G proteins (1-3). Each RGS has a distinct structure, expression pattern, and regulation, resulting in preferential interactions with receptors, G proteins, and other signaling proteins, as well as a unique function (4).
Regulator of G-protein signaling 4 (RGS4) is a small RGS (23 kDa) that belongs to the R4 subfamily of heterotrimeric G-protein regulators. RGS4 contains a short amino-terminus that may be responsible for its functional specificity towards G-protein-coupled receptors, and a conserved RGS domain responsible for GAP activity (1). The RGS4 protein shares activity at both Gαq and Gαi/o proteins (5,6). Degradation of RGS4 is regulated by opioid receptor-mediated ubiquitination following stimulation by opioid receptor agonists, such as the DAMGO synthetic opioid peptide (7). RGS4 modulates the action of morphine and other opiates in vivo (8).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
