背景信息

AXIN2 (Axis Inhibition Protein 2) is a key regulatory protein in the Wnt/β-catenin signaling pathway, which plays a critical role in embryonic development, tissue homeostasis, and stem cell maintenance. It functions as a scaffold protein in the β-catenin destruction complex, facilitating the phosphorylation and subsequent degradation of β-catenin. This process tightly regulates Wnt signaling activity, ensuring controlled cell proliferation and differentiation. Dysregulation of AXIN2 is implicated in various diseases, including colorectal cancer, hepatocellular carcinoma, and fibrotic disorders, where aberrant Wnt signaling drives uncontrolled cell growth.

Structurally, AXIN2 contains multiple domains for protein-protein interactions, including a regulator of G-protein signaling (RGS) domain that binds adenomatous polyposis coli (APC), a β-catenin-binding region, and a DIX domain mediating oligomerization. Its expression is both constitutive and inducible; Wnt activation itself upregulates AXIN2 via a negative feedback loop, making it a transcriptional target and biomarker of active Wnt signaling.

Recombinant AXIN2 protein is engineered in vitro using expression systems like *E. coli* or mammalian cells, often tagged with affinity markers (e.g., His-tag) for purification. It is widely used in biochemical assays to study Wnt pathway mechanisms, screen therapeutic inhibitors, or reconstitute protein complexes. Researchers also leverage recombinant AXIN2 to explore tissue regeneration, as Wnt signaling modulation influences stem cell behavior. Mutations in AXIN2 are linked to familial tooth agenesis and osteopathies, highlighting its developmental importance. Its dual role as a pathway component and feedback regulator makes it a compelling target for therapeutic intervention in cancer and regenerative medicine.
