Biochem/physiol Actions QS11 is an inhibitor of GTPase activating protein of ADP-ribosylation factor 1 (ARFGAP1), as well as a synergizer of the Wnt/β-catenin signaling pathway. The Wnt/β-catenin signaling pathway regulates cell morphology, motility, proliferation, and differentiation during development. The GTPase activating protein of ADP-ribosylation factors (ARFGAPs) regulates the small GTPase ADP-ribosylation factors (ARFs) that mediate a number of biological processes, including vesicle trafficking and cytoskeleton reorganization. QS-11 binds and inhibits GTPase activating protein of ADP-ribosylation factor1 (ARFGAP1). Inhibition of ARFGAPs increases the level of activated ARF and subsequent β-catenin translocation leading to pathway activation. |
