General description

Regulator of G-protein signaling 2 (UniProt: P41220; also known as RGS2, Cell growth-inhibiting gene 31 protein, G0/G1 switch regulatory protein 8) is encoded by the RGS2 (also known as G0S8, GIG31) gene (Gene ID: 5997) in human. RGS2 is shown to regulate G protein-coupled receptor signaling cascades. It inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits, thereby driving them into their inactive GDP-bound form. It also plays a role in the regulation of blood pressure in response to signaling via G protein-coupled receptors and GNAQ. RGS2 is reported to play a role in regulating the constriction and relaxation of vascular smooth muscle and also has a protective effect against myocardial hypertrophy and atrial arrhythmias. It inhibits beta-adrenergic receptor-induced cardiomyocyte hypertrophy. Overexpression of RGS2 reduces the activity of isoproterenol-induced ERK1/2 and prevents AKT activation. Four isoforms of RGS2 have been reported that are produced by alternative splicing. (Ref.: Nunn, C et al. (2010). Cell Signal 22(8); 1231-1239).
