Background:
CCG-50014 is a potent and small molecule RGS inhibitor (IC50= 30 nM for RGS4, more than 20 fold selectivity for RGS4 over other RGS proteins). It is a GTPase activating protein that binds to the Gα –subunits of activated heterotrimeric G-proteins and boost GTP hydrolysis rate. [1][2]
RGS (regulator of G protein signaling) inactivates G proteins by promoting GTPase hydrolysis ability of the alphas subunit, thus inhibits the G protein signaling transduction.
In living HEK293T cells, CCG-50014 inhibited Gαo-dependent membrane translocation of GFP-RGS4. HEK293T cell transfected with GFP-RGS4 and Gαo with vehicle (0.1% DMSO) did not changed the membrane localization of RGS4, CCG-50014 (100 μM) reversed the membrane localization of RGS. [1]
