RGS Protein

RGS protein inhibitors act on regulators of G protein signaling that switch off active Gα subunits. Regulator of G protein signaling (RGS) proteins share a conserved RGS domain that binds the GTP-bound Gα subunit. In 1996, RGS4 and the Gα-interacting protein (GAIP) were shown to be GTPase-activating proteins for the Gi subfamily of Gα subunits. By speeding GTP hydrolysis, RGS proteins shorten the signals sent by many G protein-coupled receptors (GPCRs). CCG-4986 came from a 2007 flow cytometry screen for compounds that disrupt binding between RGS4 and Gα. CCG-63802 and CCG-63808, described in 2010, are reversible inhibitors that act at an allosteric site. CCG 50014 is listed as an RGS4 inhibitor, and the set also includes RGS10 and RGS14 modulators.

    RGS10 modulator-1

    RGS10 modulator-1 functions as a potent modulator of the RGS10 protein, exhibiting significant biological activity by reversing interferon-gamma (IFNγ)-induced expression of RGS10 protein and mRNA. Additionally, this compound effectively reduces the levels of COX-2 mRNA and inducible nitric oxide synthase (iNOS) expression that are stimulated by IFNγ. RGS10 modulator-1 is a valuable tool for research exploring the regulatory mechanisms of RGS10 in inflammatory responses and related signaling pathways.
