is a negative regulator of the Wnt pathway, which is critical in stem cell signaling, morphogenesis, the mesenchymal-epithelial transition, and many cancers. Axin functions as a tumor suppressor. Probably facilitates the phosphorylation of beta-catenin and APC by GSK3B, leading to their ubiquitination and subsequent proteolysis. Is downregulated during progression of esophageal squamous cell carcinoma. Axin1/2 mediate cross-talk between TGF-beta and Wnt signaling pathways.
