    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • regulating the transcription at the level of mRNA elongation
  • involved in retaining cellular transcripts in intranuclear foci and can regulate the export of mRNA to the cytoplasm
  • exert influence on mRNA trafficking and the modulation of translation rates and may constitute an innate immune translational surveillance mechanism important in host defense counter measures against virus infection
  • may be involved in the transcription and/or stabilization of selected mRNAs such as IL2 and MYOD
  • regulates inducible IL2 transcription, mRNA stability, and gene expression in T cells
  • potentially inhibits influenza virus replication during the early phase of infection through direct interaction with viral nucleoprotein
  • functional role in co- or post-transcriptional gene regulation may contribute to the neoplastic phenotype
  • constitute a novel, conserved mechanism of host defense used by the cell to detect and impede aberrant translation events
  • ILF3/ILF2 complex is a regulator of DNA damage repair mediated by DNA-dependent protein kinase (DNA-PK), suggesting that structured RNA may modulate this process
  • CELLULAR PROCESS nucleotide, transcription
    a component
  • subunit of the nuclear factor of activated T cells, heterodimerizing with ILF2
  • ILF3-ILF2 complex functions as a negative regulator in the microRNA processing pathway
    small molecule
  • ILF2
  • SERBP1 and ILF3 were identified as NR5A2 interacting partners
  • like ADARB1, underlying sequences in dsRNA may influence how ILF3 recognizes its target RNAs
