IFNAR1, one of the subunit of IFN-α/β receptor, is a type I IFN receptor. IFNAR1 forms the heterodimeric receptor with IFNAR2. IFNAR1 mediates IFN-induced STAT signaling by interacting with tyrosine kinase 2 (Tyk2) [1] [2] . Upon activation by these IFNs, IFNAR1 and IFNAR2 undergo a conformational change to promote a cascade of downstream signaling events, including the phosphorylation of Tyk2 and JAK1, STAT1 and STAT2 [3] . IFNAR1 Protein, Mouse (HEK293, His) is a recombinant mouse IFNAR1 (M1-T429) with C-terminal His tag, which is produced in HEK293 cells.

IFNAR1, one of the subunit of IFN-α/β receptor, is a type I IFN receptor. IFNAR1 is expressed on peripheral blood B cells and monocytes, and mediates differentiation and activation of these cells [4] . IFNAR1 interacts with tyrosine kinase 2 (Tyk2), and the interaction is able to stabilize IFNAR1 on the plasma membrane [1] . Besides, IFNAR1 associates with TYK2 and initiates type I IFN-induced STAT signaling, but the activation needs IFNAR2 as a platform [2] . IFN-α/-β can induce association of the IFNAR1 and IFNAR2, and makes JAK1 and TYK2 form a functional signaling unit [1] . Upon activation by these IFNs, IFNAR1 and IFNAR2 undergo a conformational change to promote a cascade of downstream signaling events. The signaling events includes the phosphorylation of Tyk2 and JAK1, the signal transducers and activators of transcription STAT1 and STAT2, and the formation of the IFN-stimulated gene factor 3 (ISGF3) complex which consists of phosphorylated STAT1 and STAT2 and IRF9 [3] . The lack of IFNAR1 in mice makes mice highly susceptible to bacteria and parasites infection, IFNAR1-deficiency in mice also accelerates tumor growth [5] [6] . The sequence of amino acids in IFNAR1 differs in different species. Human IFNAR1 shares IFNAR1 mediates IFN-induced STAT signaling by interacting with tyrosine kinase 2 (Tyk2) [1] .
