CC -!- FUNCTION: Component of the receptor for type I interferons, including
CC interferons alpha, IFNB1 and IFNW1 (PubMed:2153461, PubMed:7665574,
CC PubMed:10049744, PubMed:14532120, PubMed:15337770, PubMed:21854986).
CC Functions in general as heterodimer with IFNAR2 (PubMed:7665574,
CC PubMed:10049744, PubMed:21854986). Type I interferon binding activates
CC the JAK-STAT signaling cascade, and triggers tyrosine phosphorylation
CC of a number of proteins including JAKs, TYK2, STAT proteins and the
CC IFNR alpha- and beta-subunits themselves (PubMed:7665574,
CC PubMed:21854986, PubMed:32972995). Can form an active IFNB1 receptor by
CC itself and activate a signaling cascade that does not involve
CC activation of the JAK-STAT pathway (By similarity).

CC -!- SUBUNIT: Heterodimer with IFNAR2 (PubMed:7665574, PubMed:10049744,
CC PubMed:21854986). Interacts with STAT1 and STAT2; the interaction
CC requires its phosphorylation at Tyr-466 (PubMed:9121453). Interacts
CC with TYK2 (PubMed:7526154, PubMed:15337770, PubMed:24704786). Interacts
CC (serine-phosphorylated form) with FBXW11, the substrate recognition
CC component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein
CC ligase complex (PubMed:14532120, PubMed:15337770, PubMed:18056411).
CC Interacts with SHMT2; this promotes interaction with ABRAXAS2 and the
CC BRISC complex (PubMed:24075985). Interacts with TRIM10; this
CC interaction prevents association between IFNAR1 and TYK2

CC -!- TISSUE SPECIFICITY: IFN receptors are present in all tissues and even
CC on the surface of most IFN-resistant cells. Isoform 1, isoform 2 and
CC isoform 3 are expressed in the IFN-alpha sensitive myeloma cell line
CC U266B1. Isoform 2 and isoform 3 are expressed in the IFN-alpha
CC resistant myeloma cell line U266R. Isoform 1 is not expressed in IFN-
CC alpha resistant myeloma cell line U266R. {ECO:0000269|PubMed:8307198}.
CC -!- PTM: Ubiquitinated, leading to its internalization and degradation
CC (PubMed:14532120, PubMed:15337770). Polyubiquitinated via 'Lys-48'-
CC linked and 'Lys-63'-linked ubiquitin chains, leading to receptor
CC internalization and lysosomal degradation (PubMed:18056411). The 'Lys-
CC 63'-linked ubiquitin chains are cleaved off by the BRISC complex
CC (PubMed:24075985). {ECO:0000269|PubMed:14532120,
CC ECO:0000269|PubMed:15337770, ECO:0000269|PubMed:18056411,
CC ECO:0000269|PubMed:24075985}.
CC -!- PTM: Phosphorylated on serine residues in response to interferon
CC binding; this promotes interaction with FBXW11 and ubiquitination
CC (PubMed:14532120, PubMed:15337770, PubMed:24075985). Phosphorylated on
CC tyrosine residues by TYK2 tyrosine kinase (PubMed:7526154).
CC Phosphorylated on tyrosine residues in response to interferon
CC (PubMed:10049744). {ECO:0000269|PubMed:10049744,

CC ECO:0000269|PubMed:7526154}.
CC -!- PTM: Palmitoylation at Cys-463 is required for the activation of STAT1
CC and STAT2. {ECO:0000269|PubMed:19561067}.
CC -!- MISCELLANEOUS: [Isoform 2]: Incomplete sequence. {ECO:0000305}.
CC -!- MISCELLANEOUS: [Isoform 3]: Incomplete sequence. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the type II cytokine receptor family.
CC {ECO:0000305}.
