Interferon-α/β Receptor 1 is a dimeric, disulfide-linked protein that binds human interferons α and β. This receptor also interacts with Tyr kinase JAK1, and thereby regulates cellular signaling across the membranes . Anti-Interferon-α/β Receptor 1 is specific for recombinant human IFN-α/β R1 and does not react with recombinant human IFN-γ RI and IFN-γ RII.
