Description : CCG-63808 is a selective inhibitor of RGS4 with IC50 value of 1.4 μM [1].RGS (regulators of G protein signaling) are multi-functional, GTPase-accelerating proteins and plays an important role in promoting GTP hydrolysis via heterotrimeric G proteins α subunit. RGS 4 is also known as RGP4 and plays a pivotal role in negatively regulating signaling upstream or at the level of the heterotrimeric G protein [2].CCG-63808 is a potent RGS4 inhibitor and is different from the reported RGS4 irreversibly inhibitor CCG-4986. Using the [32P] GTP single-turnover GAP assay, it was shown that CCG-63808 treatment inhibited GAP activity of RGS4 and the inhibition could be reversed by washing [1].References: [1].Blazer, L.L., et al., Reversible, allosteric small-molecule inhibitors of regulator of G protein signaling proteins.
