• Post Translation Modifications
• Ubiquitinated, leading to its internalization and degradation (PubMed:14532120, PubMed:15337770).
  Polyubiquitinated via 'Lys-48'-linked and 'Lys-63'-linked ubiquitin chains, leading to receptor internalization and lysosomal degradation (PubMed:18056411).
  The 'Lys-63'-linked ubiquitin chains are cleaved off by the BRISC complex (PubMed:24075985).
  Phosphorylated on tyrosine residues in response to interferon-binding: phosphorylation by TYK2 tyrosine kinase creates docking sites for STAT proteins (PubMed:7526154, PubMed:10049744).
  Phosphorylated on serine residues in response to interferon binding; this promotes interaction with FBXW11 and ubiquitination (PubMed:14532120, PubMed:15337770, PubMed:24075985).
  Palmitoylation at Cys-463 is required for the activation of STAT1 and STAT2.

• Function
• Together with IFNAR2, forms the heterodimeric receptor for type I interferons (including interferons alpha, beta, epsilon, omega and kappa) (PubMed:2153461, PubMed:7813427, PubMed:10049744, PubMed:14532120, PubMed:15337770, PubMed:24075985, PubMed:21854986).
  Type I interferon binding activates the JAK-STAT signaling cascade, resulting in transcriptional activation or repression of interferon-regulated genes that encode the effectors of the interferon response (PubMed:7665574, PubMed:10049744, PubMed:21854986).
  Mechanistically, type I interferon-binding brings the IFNAR1 and IFNAR2 subunits into close proximity with one another, driving their associated Janus kinases (JAKs) (TYK2 bound to IFNAR1 and JAK1 bound to IFNAR2) to cross-phosphorylate one another (PubMed:7813427, PubMed:7665574, PubMed:21854986, PubMed:32972995).
  The activated kinases phosphorylate specific tyrosine residues on the intracellular domains of IFNAR1 and IFNAR2, forming docking sites for the STAT transcription factors (PubMed:7813427, PubMed:7526154, PubMed:7665574, PubMed:21854986, PubMed:32972995).
  STAT proteins are then phosphorylated by the JAKs, promoting their translocation into the nucleus to regulate expression of interferon-regulated genes (PubMed:7813427, PubMed:7665574, PubMed:9121453, PubMed:19561067, PubMed:21854986, PubMed:32972995).
  Can also act independently of IFNAR2: form an active IFNB1 receptor by itself and activate a signaling cascade that does not involve activation of the JAK-STAT pathway (By similarity).
