ILF2 (Interleukin Enhancer Binding Factor 2), also known as NF45 or NFAR2. is a multifunctional protein involved in transcriptional regulation, RNA processing, and DNA repair. Initially identified as a component of the nuclear factor of activated T cells (NF-AT) complex, ILF2 forms a heterodimer with ILF3 (NF90/NF110) to stabilize RNA-DNA hybrids and regulate gene expression. It contains a conserved double-stranded RNA-binding domain (dsRBD), enabling interactions with RNA and DNA, which underlies its roles in mRNA stabilization, alternative splicing, and microRNA processing.
ILF2 plays critical roles in immune regulation, particularly in T-cell activation and cytokine production. It also participates in the DNA damage response by interacting with repair proteins like Ku70/Ku80. linking it to genomic stability. Dysregulation of ILF2 has been implicated in cancer, where its overexpression correlates with tumor progression, metastasis, and chemoresistance in various malignancies (e.g., hepatocellular carcinoma, breast cancer). Additionally, ILF2 serves as a host factor for viral replication, including HIV and hepatitis B virus (HBV), making it a potential antiviral target.
Recombinant ILF2 protein is produced via heterologous expression systems (e.g., E. coli, mammalian cells) for functional studies. Its purified form enables investigations into protein-RNA/DNA interactions, structural analysis, and screening for therapeutic agents. Tags such as His or GST are often added to facilitate purification and detection. Research using recombinant ILF2 continues to elucidate its molecular mechanisms in disease pathways and its utility as a diagnostic or therapeutic biomarker.
