    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • ribonuclease L, 2', 5'-oligoisoadenylate dependent, interferon regulated pathway, playing a role in mediating resistance to virus infection and apoptosis
  • plays an important role in the antiviral and antiproliferative activities of IFN and contributes to innate immunity and cell metabolism (Bisbal 2007)
  • key enzyme in the interferon induced antiviral and anti-proliferate pathway (Madsen 2008)
  • intracellular enzyme that is vital in innate immunity, but also is a tumor suppressor candidate (Al Ahmadi 2009)
  • RNASEL is an essential regulator of adipogenesis via the regulation of DDIT3 mRNA
  • novel function of RNASEL as an inducer of autophagy that affects viral yields
  • novel role of RNASEL in inducing autophagy affecting the outcomes of viral pathogenesis
  • regulates the expression of certain inflammatory genes
  • contributes to innate immunity through regulating macrophage functions
  • is closely connected with the pathogenesis and development of esophageal carcinoma, which act through the cellular pathways of RNASEL
  • RNA cleavage events catalyzed by RNASEL are required for optimal inflammasome activation during viral infections
  • is an antiviral endonuclease activated in virus-infected cells and cleaving viral and cellular single-stranded RNAs to produce small double-stranded RNAs with roles in amplifying host responses
  • is a regulated endoribonuclease that functions in the interferon antiviral response
  • is a negative regulator of cell migration
    PHYSIOLOGICAL PROCESS immunity/defense
    a component
  • heterodimer with ABCE1, ABCE1 protein inhibits the IFN-depended RNASEL system and regulates a broad range of biological functions including viral infection, tumor cell proliferation, and antiapoptosis
    small molecule
  • interaction between the androgen receptor and RNASEL mediates a cross-talk between the interferon and androgen signaling pathways
  • DDIT3 is a specific RNASEL target
  • IFN regulation by RNASEL is suggested to contribute to tissue protection and survival during viral infections
  • tristetraprolin (TTP) and RNASEL proteins interacted in cells suggesting that RNASEL is directed to cleave TTP-bound RNAs as a mechanism of substrate specificity
  • interaction between the antiviral endoribonuclease RNASEL and the actin-binding protein FLNA that enhances host defense by preventing viral entry into naive cells
  • can bind to several cytoskeletal proteins, including FLNA, an actin-binding protein that collaborates with RNASEL to maintain the cellular barrier to viral entry
  • interaction of RNASEL with the E3 ubiquitin ligase and scaffolding protein LNX1, a regulator of tight junction proteins
  • RNASEL inhibitor, ABCE1 is currently recognized as an essential translation factor involved in several stages of eukaryotic translation and ribosome biogenesis
  • cell & other
    activated by the binding of unusual oligoadenylates (2-5A) and acts as the effector enzyme of the 2-5A system, an interferon-induced anti-virus mechanism
