背景信息

**Background of NFX1 Recombinant Protein**

NFX1 (Nuclear Transcription Factor, X-box Binding 1) is a protein encoded by the *NFX1* gene, which plays diverse roles in transcriptional regulation, cellular differentiation, and immune response modulation. Initially identified for its involvement in major histocompatibility complex (MHC) class II gene regulation, NFX1 interacts with conserved X-box promoter elements and collaborates with other transcription factors to modulate gene expression. It exists in multiple splice variants, with NFX1-123 and NFX1-91 being the most studied isoforms. NFX1-123. for instance, acts as a transcriptional repressor, while NFX1-91 exhibits E3 ubiquitin ligase activity, influencing protein degradation pathways.

The recombinant NFX1 protein is engineered through molecular cloning, typically expressed in bacterial (e.g., *E. coli*) or eukaryotic systems (e.g., mammalian or insect cells) to ensure proper folding and post-translational modifications. This recombinant form retains functional domains, such as the RING finger and leucine-rich repeats, critical for its interactions and enzymatic activities. Its production enables mechanistic studies on NFX1’s role in cellular processes, including telomerase regulation, viral pathogenesis (e.g., HPV and HIV), and cancer progression. For example, NFX1 suppresses telomerase by destabilizing *hTERT* mRNA, linking it to aging and oncogenesis.

Research utilizing recombinant NFX1 has advanced understanding of its dual roles in tumor suppression and viral replication, highlighting its therapeutic potential. Structural and functional analyses of this protein also aid in developing targeted therapies for cancers and infectious diseases. Overall, NFX1 recombinant protein serves as a vital tool for dissecting molecular pathways and validating drug candidates.
