CC -!- FUNCTION: Associates with IFNAR1 to form the plasma membrane receptor
CC in the type I interferon signaling pathway (PubMed:26424569,
CC PubMed:28165510, PubMed:32972995). Directly involved in signal
CC transduction through its association with the TYR kinase JAK1
CC (PubMed:8181059, PubMed:7665574, PubMed:7759950). Involved in
CC interferon-mediated STAT1, STAT2 and STAT3 activation (PubMed:26424569,

CC transcriptional factors STAT1 and STAT2 (PubMed:9121453,
CC PubMed:28165510). Interacts with JAK1 (PubMed:8181059, PubMed:7759950).
CC Interacts with USP18; indirectly via STAT2, it negatively regulates the
CC assembly of the ternary interferon-IFNAR1-IFNAR2 complex and therefore
CC type I interferon signaling (PubMed:28165510).

CC -!- TISSUE SPECIFICITY: Isoform 3 is detected in the urine (at protein
CC level) (PubMed:8181059, PubMed:7759950). Expressed in blood cells.
CC Expressed in lymphoblastoid and fibrosarcoma cell lines.
CC {ECO:0000269|PubMed:7588638, ECO:0000269|PubMed:7759950,
CC ECO:0000269|PubMed:8181059}.
CC -!- PTM: Phosphorylated on tyrosine residues upon interferon binding.
CC Phosphorylation at Tyr-337 or Tyr-512 are sufficient to mediate
CC interferon dependent activation of STAT1, STAT2 and STAT3 leading to
CC antiproliferative effects on many different cell types.
CC {ECO:0000269|PubMed:11682488, ECO:0000269|PubMed:12105218,

CC -!- PTM: Glycosylated. {ECO:0000269|PubMed:8181059}.
CC -!- POLYMORPHISM: Genetic variations in IFNAR2 influence susceptibility to
CC hepatitis B virus (HBV) infection [MIM:610424].
CC -!- DISEASE: Immunodeficiency 45 (IMD45) [MIM:616669]: An autosomal
CC recessive disorder characterized by increased susceptibility to viral
CC infection due to impaired antiviral immunity, resulting in infection-
CC associated encephalopathy. Affected individuals are at risk for
CC developing fatal encephalitis after routine measles/mumps/rubella (MMR)
CC vaccination. {ECO:0000269|PubMed:26424569}. Note=The disease is caused
CC by variants affecting the gene represented in this entry.
CC -!- MISCELLANEOUS: [Isoform 3]: Soluble receptor. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the type II cytokine receptor family.
