Regulator of G-protein signaling (RGS) proteins in cancer biology

Biochem Pharmacol. 2009 Nov 15;78(10):1289-97. doi: 10.1016/j.bcp.2009.06.028. Epub 2009 Jun 25.


The regulator of G-protein signaling (RGS) family is a diverse group of multifunctional proteins that regulate cellular signaling events downstream of G-protein coupled receptors (GPCRs). In recent years, GPCRs have been linked to the initiation and progression of multiple cancers; thus, regulators of GPCR signaling are also likely to be important to the pathophysiology of cancer. This review highlights recent studies detailing changes in RGS transcript expression during oncogenesis, single nucleotide polymorphisms in RGS proteins linked to lung and bladder cancers, and specific roles for RGS proteins in multiple cancer types.
