Recombinant human DNASE2 (rhDNASE2), also known as deoxyribonuclease II, is a lysosomal endonuclease that hydrolyzes DNA under acidic conditions, playing critical roles in nucleic acid degradation and cellular homeostasis. Unlike DNASE1. which functions at neutral pH, DNASE2 requires an acidic environment (pH 4.5–5.5) for activity and is calcium-independent. It is primarily involved in degrading DNA from apoptotic cells, ingested microbes, and endogenous sources within lysosomes, ensuring proper clearance of genetic material to prevent autoimmune responses. Dysregulation of DNASE2 is linked to pathologies such as systemic lupus erythematosus, chronic inflammation, and impaired embryonic development.
Produced via genetic engineering in eukaryotic systems (e.g., mammalian or insect cells), rhDNASE2 retains post-translational modifications essential for its stability and function. Its recombinant form enables studies on DNA degradation mechanisms, lysosomal biology, and autoimmune disorders. Therapeutic applications are being explored, including adjuvant therapies for diseases involving accumulated extracellular DNA, such as cystic fibrosis or cancer. Recent research also highlights its potential in mitigating neutrophil extracellular trap (NET)-related inflammation. The availability of rhDNASE2 has advanced both basic research and drug development, offering tools to dissect its biological roles and test novel treatment strategies.
