Protein function

Component of the receptor for type I interferons, including interferons alpha, IFNB1 and IFNW1 (PubMed:2153461, PubMed:7665574, PubMed:10049744, PubMed:14532120, PubMed:15337770, PubMed:21854986). Functions in general as heterodimer with IFNAR2 (PubMed:7665574, PubMed:10049744, PubMed:21854986). 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:7665574, PubMed:21854986). Can form an active IFNB1 receptor by itself and activate a signaling cascade that does not involve activation of the JAK-STAT pathway (By similarity). .

Protein tissue specificity

IFN receptors are present in all tissues and even on the surface of most IFN-resistant cells. Isoform 1, isoform 2 and isoform 3 are expressed in the IFN-alpha sensitive myeloma cell line U266B1. Isoform 2 and isoform 3 are expressed in the IFN-alpha resistant myeloma cell line U266R. Isoform 1 is not expressed in IFN-alpha resistant myeloma cell line U266R. .

Protein sequence and domain

Belongs to the type II cytokine receptor family. ; Contains 4 fibronectin type-III domains.

Protein post-translational 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 serine residues in response to interferon binding; this promotes interaction with FBXW11 and ubiquitination (PubMed:14532120, PubMed:15337770, PubMed:24075985). Phosphorylated on tyrosine residues by TYK2 tyrosine kinase (PubMed:7526154). Phosphorylated on tyrosine residues in response to interferon (PubMed:10049744). .; Palmitoylation at Cys-463 is required for the activation of STAT1 and STAT2. .

Protein cellular localization

Isoform 1: Cell membrane ; Single-pass type I membrane protein . Late endosome . Lysosome . Note=Interferon binding triggers internalization of the receptor from the cell membrane into endosomes and then into lysosomes. .
