SEQUENCE SIMILARITIES

Belongs to the type II cytokine receptor family.

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.

POST-TRANSLATIONAL MODIFICATION

Ubiquitinated, leading to its internalization and degradation. Polyubiquitinated via 'Lys-48'-linked and 'Lys-63'-linked ubiquitin chains, leading to receptor internalization and lysosomal degradation. The 'Lys-63'-linked ubiquitin chains are cleaved off by the BRISC complex.; Phosphorylated on serine residues in response to interferon binding; this promotes interaction with FBXW11 and ubiquitination. Phosphorylated on tyrosine residues by TYK2 tyrosine kinase. Phosphorylated on tyrosine residues in response to interferon.; Palmitoylation at Cys-463 is required for the activation of STAT1 and STAT2.

SUBCELLULAR LOCATION

Cell membrane, Late endosome, Lysosome.

FUNCTION

The type I interferons (IFNs), α and β, are a group of structurally and functionally related proteins that are induced by either viruses or double stranded RNA and defined by their ability to confer an antiviral state in cells. The α and β IFNs appear to compete with one another for binding to a common cell surface receptor, while immune IFN (IFNγ) binds to a distinct receptor. The latter protein, IFN-αR, is only weakly responsive to type I interferons in contrast to IFN-α/βR, which binds to and responds effectively to IFN-β and to several of the IFN-? subtypes. Moreover, IFN-α/βR is physically associated with the cytoplasmic tyrosine kinase JAK1 and thus, in addition to ligand binding, appears to be functionally involved in signal transduction. IFN-αR1 is a receptor for IFN-α/β and is present as the full chain (IFN-αR1a) and as a splice-variant (IFN-αR1). The IFN-γ receptor complex consists of an alpha subunit (IFN-γRα) and a beta subunit that is 332 amino acids in length (mouse) and 337 amino acids in length (human).
