**Background of RNASE12 Recombinant Protein**
RNASE12. a member of the ribonuclease A (RNASE) superfamily, is a relatively understudied protein encoded by the *RNASE12* gene in humans. This gene is located on chromosome 14q11.2 and shares structural homology with other RNASE family members, characterized by conserved catalytic motifs involved in RNA hydrolysis. Unlike its well-characterized relatives (e.g., RNASE1 or RNASE2/angiogenin), the precise biological role of RNASE12 remains unclear. It is speculated to participate in RNA metabolism, host defense, or innate immunity, though experimental evidence is limited.
Recombinant RNASE12 refers to the protein produced *in vitro* using recombinant DNA technology, often expressed in bacterial (e.g., *E. coli*) or eukaryotic systems (e.g., mammalian cells). This approach enables large-scale production of the protein for functional studies. Researchers utilize recombinant RNASE12 to explore its enzymatic activity, substrate specificity, and potential interactions with cellular components. Preliminary studies suggest it may exhibit ribonucleolytic activity, albeit weaker than other RNASES, and could play a role in modulating inflammatory responses or RNA degradation pathways.
Interest in RNASE12 also stems from its potential clinical relevance. Altered expression of RNASE family proteins has been linked to pathologies such as cancer, neurodegeneration, and autoimmune diseases. Recombinant RNASE12 could serve as a tool to investigate its involvement in these conditions or to develop therapeutic strategies. However, challenges persist, including resolving its 3D structure, clarifying tissue-specific expression patterns, and defining its physiological substrates. Current research focuses on bridging these gaps to uncover its role in health and disease, leveraging recombinant protein technology for mechanistic and translational insights.
