Supplementary information

The ILF3 protein also known as Interleukin enhancer-binding factor 3 plays an important role in cellular mechanisms. It has a molecular mass of approximately 90 kDa and is expressed broadly in various tissues such as the liver kidney and spleen. ILF3 is part of the double-stranded RNA-binding proteins and it engages in regulating RNA metabolism processes. Scientists also refer to ILF3 as NF90 and it is known for its function in modulating gene expression by interacting with RNA.
Biological function summary

ILF3 interacts with RNA and proteins within the cell to control the stability and translation of mRNA. It acts as a component of various ribonucleoprotein complexes indicating its role in post-transcriptional regulation. ILF3 can bind to double-stranded RNA and single-stranded RNA motifs affecting the proliferation and differentiation of cells in which it is expressed. It also contributes significantly in cellular stress responses impacting how cells respond to environmental changes.

Pathways

ILF3 is involved in important cellular pathways such as RNA processing and antiviral defense mechanisms. In the RNA processing pathway ILF3 associates with proteins such as Drosha impacting microRNA biogenesis. Additionally in antiviral responses it identifies and binds viral RNAs initiating defensive cellular responses. These pathways position ILF3 as integral to maintaining cellular homeostasis during stress and infection.

ILF3 has connections to cancer and viral infections. Aberrations in ILF3 expression or function are observed in certain cancers where it influences tumor progression by interacting with oncogenic pathways. In viral infections like those caused by hepatitis C virus ILF3 contributes to host defense by modulating immune responses. It interacts with proteins like RIG-I in the context of viral infections facilitating antiviral signaling pathways to control disease progression.

Target data

RNA-binding protein that plays an essential role in the biogenesis of circular RNAs (circRNAs) which are produced by back-splicing circularization of pre-mRNAs. Within the nucleus, promotes circRNAs processing by stabilizing the regulatory elements residing in the flanking introns of the circularized exons. Plays thereby a role in the back-splicing of a subset of circRNAs (PubMed : 28625552). As a consequence, participates in a wide range of transcriptional and post-transcriptional processes. Binds to poly-U elements and AU-rich elements (AREs) in the 3'-UTR of target mRNAs (PubMed : 14731398). Upon viral infection, ILF3 accumulates in the cytoplasm and participates in the innate antiviral response (PubMed : 21123651, PubMed : 34110282). Mechanistically, ILF3 becomes phosphorylated and activated by the double-stranded RNA-activated protein kinase/PKR which releases ILF3 from cellular mature circRNAs. In turn, unbound ILF3 molecules are able to interact with and thus inhibit viral mRNAs (PubMed : 21123651, PubMed : 28625552).. (Microbial infection) Plays a positive role in HIV-1 virus production by binding to and thereby stabilizing HIV-1 RNA, together with ILF3.
