**Background of RNASE13 Recombinant Protein**
RNASE13. a member of the ribonuclease A (RNASE) superfamily, is a vertebrate-specific enzyme implicated in RNA metabolism and host defense mechanisms. This protein family, characterized by conserved catalytic motifs and disulfide bond patterns, plays roles in cleaving RNA substrates, contributing to processes such as angiogenesis, immune regulation, and antimicrobial activity. RNASE13 is encoded by the *RNASE13* gene, which shares structural homology with other RNASEs but exhibits distinct tissue expression profiles and substrate preferences.
Recombinant RNASE13 refers to the engineered version of the protein produced using heterologous expression systems (e.g., *E. coli*, yeast, or mammalian cells*). Its production involves cloning the *RNASE13* gene into expression vectors, followed by purification via affinity chromatography to ensure high purity and bioactivity. Recombinant technology allows for scalable production, enabling functional studies and therapeutic exploration. Structurally, recombinant RNASE13 retains conserved features, including catalytic residues (e.g., His-Lys-His triad) and disulfide bonds critical for enzymatic stability.
Functionally, RNASE13 is hypothesized to participate in innate immunity by degrading pathogen-derived RNA or modulating host RNA to regulate inflammatory responses. Studies suggest its potential antimicrobial and antiviral properties, though detailed mechanisms remain under investigation. Additionally, aberrant RNASE13 expression has been linked to certain cancers and inflammatory diseases, highlighting its dual role in homeostasis and pathology.
Recombinant RNASE13 serves as a vital tool for elucidating its biological roles, screening inhibitors, and developing RNA-targeted therapies. Its applications span basic research (e.g., enzymatic assays, protein-RNA interaction studies) and translational medicine, including drug candidates for infections or immune disorders. Further research is needed to fully unravel its physiological significance and therapeutic potential.
