Recombinant human DEFB136 protein is a synthesized form of the endogenous DEFB136 (Defensin Beta 136), a member of the β-defensin family. Defensins are small, cationic antimicrobial peptides integral to innate immunity, functioning in microbial defense, immune modulation, and wound healing. β-defensins, secreted primarily by epithelial cells, exhibit broad-spectrum antimicrobial activity against bacteria, viruses, and fungi by disrupting microbial membranes. DEFB136. located on chromosome 20. is less characterized compared to other β-defensins but is hypothesized to play roles in mucosal immunity, particularly in reproductive, respiratory, or dermal tissues.
Recombinant DEFB136 is produced using heterologous expression systems (e.g., *E. coli* or yeast) to enable scalable, high-purity yields for research and therapeutic exploration. Studies focus on elucidating its structural motifs, receptor interactions, and signaling pathways. Its potential applications span antimicrobial therapies, immune adjuvants, and regenerative medicine. Additionally, DEFB136 may contribute to pathological conditions, including chronic inflammation or cancer, underscoring its dual role in health and disease.
The recombinant protein overcomes challenges in studying endogenous DEFB136. which is low in natural abundance and difficult to isolate. However, ensuring proper post-translational modifications (e.g., disulfide bonds critical for stability) remains a technical hurdle. Ongoing research aims to validate its biological activities and harness its therapeutic potential while addressing scalability and functional consistency. DEFB136 exemplifies the complexity of defensins in host-pathogen interactions and their untapped promise as multifunctional immune modulators.
