Purity > 90% as determined by SDS-PAGE. MW: 41.5kDa. Full Length: 1-126aa. N-terminal GST-tagged. Homo sapiens (Human). Inhibits the Wnt/Wingless pathway by binding to CTNNB1/beta-catenin and inhibiting beta-catenin-mediated transcriptional activation through competition with TCF/LEF transcription factors. Has also been shown to play a role in regulating the intracellular trafficking of polycystin-2/PKD2 and possibly of other intracellular proteins. Promotes adipocyte and cardiomyocyte differentiation.
