Evidence Summary from Illumina curation team: The ILF3 gene encodes two alternatively spliced and ubiquitously expressed RNA binding protein isoforms, NF110 and NF90. NF110 and NF90 have been shown to interact with viral RNAs and proteins to inhibit the replication of a number of viruses, including PV-RIPO, a chimeric poliovirus and human rhinovirus; HIV-1, and vesicular stomatitis virus (VSV) (reviewed Castella et al. 2015). Conversely, NF110 and NF90 have also been associated with the enhancement of viral replication in the case of DNA hepatitis B virus (HBV), ssRNA viruses from the Flaviviridae family, hepatitis C virus and influenza B (FLUBV) (reviewed Castella et al. 2015; Patzina et al, 2017). Recently, Watson et al (2020) demonstrated a role for the ILF3 isoforms in enhancing the translation of IFNB1 and ISGs in response to a viral infection. Depletion of NF90/NF110 from HeLa cells using siRNA resulted in an impaired antiviral activity with a reduction in the expression of ISG proteins and conditioned medium generated in ILF3-depleted cells conferred less resistance to Echovirus 7 infection. The specific depletion of NF110 was shown to cause a decrease in the association of IFNB1 mRNA with the polysomal fractions in poly(I:C) stimulated conditions (Watson et al. 2020).
