背景信息

Anterior Gradient 2 (AGR2), a member of the protein disulfide isomerase (PDI) family, is a secreted chaperone protein primarily localized in the endoplasmic reticulum (ER). First identified in *Xenopus laevis* for its role in embryonic development, AGR2 is evolutionarily conserved and plays critical roles in protein folding, ER stress response, and maintenance of epithelial tissue homeostasis. Structurally, it contains a thioredoxin-like domain with a CXXS motif, enabling redox activity and disulfide bond formation in substrate proteins, particularly those involved in mucus production and cellular adhesion.

AGR2 is highly expressed in secretory epithelial cells, such as those in the gastrointestinal tract, and is implicated in wound healing, inflammation, and cancer. It interacts with client proteins like intestinal mucin MUC2 and growth factor receptors, modulating their stability and function. Dysregulation of AGR2 is linked to pathologies including inflammatory bowel disease (IBD) and multiple cancers (e.g., breast, prostate, lung), where it often promotes tumor progression by enhancing cell survival, metastasis, and chemoresistance. Paradoxically, AGR2 also exhibits tumor-suppressive roles in certain contexts, highlighting its context-dependent functionality.

Recombinant AGR2 protein, typically produced in *E. coli* or mammalian expression systems, retains biological activity and is widely used to study its molecular mechanisms, develop diagnostic biomarkers, or explore therapeutic strategies. Its applications span *in vitro* assays (e.g., protein interaction studies), antibody development, and disease modeling. Research on AGR2 continues to unravel its dual roles in health and disease, positioning it as a potential therapeutic target or tool for regenerative medicine.
