背景信息

**Background of PXDN Recombinant Protein**

Peroxidasin (PXDN), also known as Vascular Peroxidase 1 (VPO1), is a multidomain extracellular matrix (ECM)-associated enzyme belonging to the heme peroxidase family. It is encoded by the *PXDN* gene and is evolutionarily conserved across species. PXDN is structurally characterized by its N-terminal leucine-rich repeats (LRRs), a immunoglobulin (Ig) domain, and a C-terminal peroxidase domain, which collectively enable its diverse functional roles.

Originally identified for its peroxidase activity, PXDN catalyzes the formation of sulfilimine bonds, critical cross-links that stabilize the collagen IV network in basement membranes. This enzymatic function is essential for maintaining ECM integrity, particularly in tissues such as the kidney glomerulus and ocular structures. Dysregulation of PXDN has been implicated in pathological conditions, including congenital eye disorders (e.g., microcoria), fibrosis, and cancer progression, where aberrant ECM remodeling occurs.

Recombinant PXDN protein is engineered to study its biochemical properties and mechanisms in vitro. Produced using expression systems like mammalian cells or insects (to ensure proper post-translational modifications), the recombinant form retains enzymatic activity and structural fidelity. Researchers employ it to investigate interactions with ECM components, redox signaling pathways, and its role in oxidative stress responses. Notably, PXDN-generated hypohalous acids may contribute to ECM modification and inflammatory processes, linking it to age-related diseases.

In cancer biology, PXDN overexpression correlates with tumor invasiveness and metastasis, potentially serving as a biomarker or therapeutic target. Its recombinant variant aids in high-throughput screening for inhibitors and elucidating its dual roles in tissue homeostasis and disease. Overall, PXDN recombinant protein is a vital tool for dissecting ECM biology and developing interventions for PXDN-associated disorders.
