RGS4 Antibody recognizes endogenous levels of total RGS4 protein.
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Cys33 of human RGS4 protein. Antibodies are purified by protein A and peptide affinity chromatography.
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).
RGS4 is a small RGS of 23 kDa that belongs to the R4 subfamily of RGS. It harbors a short N-terminus thought to be critical for its functional specificity towards GPCRs and a RGS homology domain (RH domain) (5). RGS4 shares activity at both Gαq (6) and Gαi/o proteins (7).
RGS4 degradation is regulated by opioid receptor-mediated ubiquitination after stimulation by opioid receptor agonists such as DAMGO (8); and RGS4 modulates the action of morphine and other opiates in vivo (9).
