Interferon receptor (IFNR) is a cell surface receptor which binds interferon. Interferon α/β receptor binds interferon-α and interferon-β. It is a heterodimer with subunits INFAR1 and INFAR2. Interferon γ receptor binds interferon-γ and is a heterodimer with subunits INFGR1 and INFGR2. Interferon δ receptor binds interferon-δ.
