CC -!- FUNCTION: Component of the receptor for type I interferons, including
CC interferons alpha, IFNB1 and IFNW1. Functions in general as heterodimer
CC with IFNAR2. Type I interferon binding activates the JAK-STAT signaling
CC cascade, and triggers tyrosine phosphorylation of a number of proteins
CC including JAKs, TYK2, STAT proteins and the IFNR alpha- and beta-
CC subunits themselves (By similarity). Can form an active IFNB1 receptor
CC by itself and activate a signaling cascade that does not involve
CC activation of the JAK-STAT pathway (By similarity).
CC {ECO:0000250|UniProtKB:P17181, ECO:0000250|UniProtKB:P33896}.
CC -!- SUBUNIT: Heterodimer with IFNAR2. Interacts with STAT1 and STAT2; the
CC interaction requires its phosphorylation at Tyr-467. Interacts with
CC TYK2. Interacts (serine-phosphorylated form) with FBXW11, the substrate
CC recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-
CC protein ligase complex. Interacts with SHMT2; this promotes interaction
CC with ABRAXAS2 and the BRISC complex. Interacts with TRIM10; this
CC interaction prevents association between IFNAR1 and TYK2.
CC {ECO:0000250|UniProtKB:P17181}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P17181};
CC Single-pass type I membrane protein {ECO:0000250|UniProtKB:P17181}.
CC Late endosome {ECO:0000250|UniProtKB:P17181}. Lysosome
CC {ECO:0000250|UniProtKB:P17181}. Note=Interferon binding triggers
CC internalization of the receptor from the cell membrane into endosomes
CC and then into lysosomes. {ECO:0000250|UniProtKB:P17181}.
CC -!- TISSUE SPECIFICITY: Expressed in the endometrium. Expressed in all
CC tissues examined except conceptus at day 15 of pregnancy.
CC {ECO:0000269|PubMed:8981227, ECO:0000269|PubMed:9348203}.
CC -!- PTM: Ubiquitinated, leading to its internalization and lysosomal
CC degradation. The 'Lys-63'-linked ubiquitin chains are cleaved off by
CC the BRISC complex; this prevents receptor internalization and
CC degradation. Probable ubiquitination sites have been identified in
CC human, but are poorly conserved across species.
CC {ECO:0000250|UniProtKB:P17181}.
CC -!- PTM: Phosphorylated on serine residues in response to interferon
CC binding; this promotes interaction with FBXW11 and ubiquitination.
CC Phosphorylated on tyrosine residues by TYK2 tyrosine kinase.
CC {ECO:0000250|UniProtKB:P17181}.
CC -!- PTM: Palmitoylation at Cys-464 is required for the activation of STAT1
CC and STAT2. {ECO:0000250|UniProtKB:P17181}.
CC -!- SIMILARITY: Belongs to the type II cytokine receptor family.
CC {ECO:0000305}.
