Product Overview
CCG-63802 is a selective inhibitor of RGS4 with IC50 value of 1.9 μM. 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. CCG-63802 is a potent RGS 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-63802 treatment inhibited GAP activity of RGS4.When tested with HEK-293 cells, administration of CCG-63802 successfully reversed 8-Br-cGMP inhibition on BK via inhibiting RGS4
