Description
FzM1.8 is an allosteric agonist of the Frizzled receptor FZD4 with pEC50 of 6.4. FzM1.8 binds to FZD4 and activates the WNT/beta-catenin pathway, by promoting TCF/LEF transcriptional activity in the absence of any WNT ligand. FzM1.8 binding stabilizes FZD4 with an increased affinity for heterotrimeric G protein and stimulates the release of the Gbetagamma subunit that in turn activates PI3K
