IWR-1-endo (4-[(3aR,4S,7R,7aS)-1,3,3a,4,7,7a-Hexahydro-1,3-dioxo-4,7-methano-2H-isoindol-2-yl]-N-8-quinolinylbenzamide)
Biochemicals Storage: 4C/-20CShipping: Blue Ice
Potent and reversible cell permeable Wnt pathway signaling inhibitor. Inhibits Wnt-induced accumulation of -catenin, leading to proteasomal degradation of this protein through a destruction complex which consists of Apc, Axin2, CK1 and GSK-3 . Stabilizes the destruction complex, increasing the level of Axin2 protein without changing the levels of Apc or GSK-3 . Tankyrase-1 (TNKS1/PARP5a) and Tankyrase-2 (TNKS2/PARP5b) inhibitor (in vitro auto-PARsylation assay).
