Functioni

Component of the receptor for type I interferons, including interferons alpha, IFNB1 and IFNW1 (PubMed:1533935, PubMed:14532120, PubMed:23872679). Functions in general as heterodimer with IFNAR2 (By similarity). Type I interferon binding activates the JAK-STAT signaling cascade, and triggers tyrosine phosphorylation of a number of proteins including JAKs, TYK2, STAT proteins and the IFNR alpha- and beta-subunits themselves (PubMed:14532120). Can form an active IFNB1 receptor by itself and activate a signaling cascade that does not involve activation of the JAK-STAT pathway (PubMed:23872679). Contributes to modulate the innate immune response to bacterial lipopolysaccharide (PubMed:23872679).By similarity4 Publications

Post-translational modificationi

Ubiquitinated (PubMed:14532120). This leads to its internalization and lysosomal degradation. The 'Lys-63'-linked ubiquitin chains are cleaved off by the BRISC complex; this prevents receptor internalization and degradation. Probable ubiquitination sites have been identified in human, but are poorly conserved across species.By similarity1 Publication

Miscellaneousi

Miscellaneous

The interferon signaling pathway is not identical between species. Thus, the interaction with STAT1 and STAT2 may not be conserved in mouse; in human it requires phosphorylation at 'Tyr-466', but the mouse protein has a Phe at the equivalent position. Likewise, cysteine palmitoylation is required for the activation of STAT1 and STAT2 in human, but the Cys is not conserved in mouse.Curated
