**Background of Recombinant Human DDX42 Protein**
The DEAD-box helicase DDX42 is a member of the DEAD-box protein family, characterized by the conserved Asp-Glu-Ala-Asp (DEAD) motif, which enables ATP-dependent RNA or DNA unwinding. DDX42 plays versatile roles in RNA metabolism, including transcription, splicing, RNA editing, and ribosome biogenesis. It also participates in DNA damage repair and innate immune responses by interacting with viral RNAs or regulating antiviral signaling pathways. Dysregulation of DDX42 has been linked to cancers, neurodegenerative disorders, and viral infections, underscoring its importance in cellular homeostasis.
Recombinant human DDX42 protein is engineered via heterologous expression systems (e.g., *E. coli* or mammalian cells) to produce a purified, functionally active form. This recombinant tool facilitates *in vitro* studies on DDX42's enzymatic activities, structural features, and molecular interactions. Researchers employ it to dissect its roles in genome stability, stress responses, and virus-host interactions. Additionally, it serves as a potential therapeutic target for drug discovery, particularly in diseases associated with RNA processing defects or aberrant helicase activity. Its application spans basic research, diagnostics, and targeted therapy development.
