**Background of DPEP2 Recombinant Protein**
Dipeptidase 2 (DPEP2), a member of the membrane-bound metallo-dipeptidase family, is a zinc-dependent enzyme implicated in hydrolyzing dipeptides and regulating bioactive peptide metabolism. It is primarily expressed in immune cells, such as neutrophils and macrophages, as well as in specific epithelial tissues, suggesting roles in immune modulation and tissue homeostasis. The DPEP2 gene resides on chromosome 16q24.3. and its protein structure includes a conserved catalytic domain with metallopeptidase activity.
Recombinant DPEP2 protein is engineered using expression systems (e.g., mammalian, insect, or bacterial cells) to produce purified, functional protein for research. Its production enables mechanistic studies on enzymatic activity, substrate specificity, and interactions with physiological or synthetic inhibitors. DPEP2 has gained attention for its potential involvement in inflammatory diseases and cancer. For instance, it is overexpressed in certain malignancies, including pancreatic ductal adenocarcinoma, where it may influence tumor microenvironment signaling.
In immunology, DPEP2 is proposed to modulate neutrophil recruitment and inflammation resolution, linking it to autoimmune disorders like rheumatoid arthritis. Structural studies of recombinant DPEP2 aid in designing targeted therapies, such as small-molecule inhibitors or antibody-based drugs. However, its precise physiological substrates and pathological mechanisms remain partially unclear, necessitating further functional characterization.
Current research focuses on elucidating DPEP2's dual roles in homeostasis and disease, leveraging recombinant protein tools to explore diagnostic or therapeutic applications. Its unique expression patterns and enzymatic properties position DPEP2 as a promising biomarker and intervention target in inflammation-driven pathologies and oncology.
