Background

Interferon-alpha/beta receptor 1 (IFN-alpha / beta R1), also known as IFNAR1, is a member of the class II cytokine receptor family of proteins. These proteins form heterodimeric receptor complexes that mediate class II cytokine signals and subunits of the different receptor complexes are shared and serve multiple functions (1). Mature human IFN-alpha / beta R1 consists of an extracellular domain (ECD) with three tandem fibronectin type III repeats, a transmembrane segment, and a cytoplasmic domain (2). Within the ECD, human IFN-alpha / beta R1 shares 47% and 50% amino acid sequence identity with mouse and rat IFN-alpha / beta R1, respectively. Alternative splicing generates two additional isoforms that lack the transmembrane segment and either all or a portion of the cytoplasmic domain. IFN-alpha / beta R1, in association with IFN-alpha / beta R2, is required for propagating anti-microbial signal transduction triggered by the type 1 interferons such as IFN-alpha and IFN-beta (3, 4). IFN-alpha / beta R1 interacts very weakly or not at all with type 1 interferons and does not stably interact with IFN-alpha / beta R2. Ligands preferentially associate with IFN-alpha / beta R2, and this complex subsequently forms a stable ternary assembly with IFN-alpha / beta R1 (5-7). IFN-alpha / beta R1 also associates with IFN-gamma R2 even in the absence of IFN-gamma stimulation (3). IFN-alpha / beta R1 activation depends on tyrosine phoshorylation as well as palmitoylation of its cytoplasmic domain (8, 9). Rapid down-regulation of the receptor is accomplished by ligand‑dependent or -independent pathways (e.g. VEGF R signaling, TLR signaling, or cellular stress) which induce its serine phosphorylation, ubiquitination, and degradation (10-13).
