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).
