Interferon alpha receptor 1 (IFN-alpha R1) is a class II cytokine receptor which belongs to type I human interferons (IFNs) family. IFNs plays a role in antiviral, antiproliferative, immunomodulatory, antitumor, and antiparasitic activities by inducing transcription of IFN-stimuated genes (ISGs) through activation of the Jak-STAT pathway. Specifically, IFN- R1 is a 135-kda signal transducing subunit of the IFN alpha/beta receptor complex (IFN-alpha R) (1). IFN-alpha R1 is phospholyated through PTK- and PKC-mediated phosphorylation, which initiates docking of STAT proteins to IFNs. This leads to activation of STAT proteins by PTK-mediated phosphorylation. The mechanism behind the amplification of IFN-alpha R complex mediated transmembrane signaling has been linked to tyrosine phosphorylation on IFN-alpha R1 (2).
