Target Data

Function Associates with IFNAR1 to form the type I interferon receptor. Receptor for interferons alpha and beta. Involved in IFN-mediated STAT1, STAT2 and STAT3 activation
Gene References into Functions
  1. The findings underline the roles of UL36USP-IFNAR2 interaction in counteracting the type I IFN-mediated signaling pathway and reveal a novel evasion mechanism of antiviral innate immunity by HSV-1. PMID: 29997210
  2. Report lowered serum IFNAR2 levels in multiple sclerosis patients are elevated on treatment with interferon-beta. PMID: 27613121
  3. this study shows that the surface expression levels of the common IFN-alpha/beta receptor subunit 2 are significantly higher on plasmacytoid dendritic cells from females in comparison to males PMID: 27891600
  4. A very small percentage of the pancreatic tumors showed strong expression of the IFNAR-2c. PMID: 25072284
  5. Lack of expression of functional IFNAR2 does not seem to be the major cause of interferon resistance in hepatitis C virus patients receiving standard interferon therapy. PMID: 26176069
  6. The effects of two functional polymorphisms, type I interferon receptor 2 gene (IFNAR2)-F8S and interleukin-10 receptor subunit beta gene (IL10RB)-K47E, on chronic hepatitis B virus (HBV) infection, were investigated. PMID: 23745570
  7. IFNAR2 overexpression was observed in various histological types of lung cancer, and appears to be associated with lung cancers that behave aggressively. PMID: 22236545
  8. In this study we have characterized the Stat2-IFNaR2 interaction and examined its role in IFNalpha signaling PMID: 11786546
  9. STAT3 activation by type I interferons is dependent on specific tyrosines located in the cytoplasmic domain of interferon receptor chain 2c PMID: 12105218
  10. Expression and signaling activity of interferon alpha/beta receptors modulates dendritic cell (DC) responsiveness during terminal maturation and differentiation of monocyte-derived DCs. PMID: 12218119
  11. Subunit 2 of the interferon alpha receptor (IFNaR2) is bound more avidly to Stat2 than is phosphorylated IFNaR1. PMID: 12220192
  12. Administration as a complex with sIFNAR-2 may provide a method of enhancing the delivery and effectiveness of type I interferons in Burkitt lymphoma in scid mice. PMID: 14980076
  13. IFNaR2, a subunit of the type I IFN receptor, is proteolytically cleaved in a regulated manner. PMID: 15286706
  14. Dynamics of the IFNAR2 extracellular domain binding site reveal highly flexible loop segments and a malleable binding surface interacting with the IFN ligand supported by a more rigid scaffold which stabilizes the binding site conformation. PMID: 15287740
  15. A dynamic model for the IFN-alpha/receptor complex predicts that IFNAR2 and IFNAR1 are probably anchored in close proximity on the cell surface and that upon IFN binding, the complex assumes a closed form, resulting in activation of intracellular kinases. PMID: 15449939
  16. IFNaR2 intracellular domain transcriptional modulation is dependent upon the carboxyl-terminal transactivation domain of Stat2. PMID: 15717316
