Product Description	Recombinant Human IFN alpha/beta R1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Lys28-Lys436.
Product Background	IFN-alpha / beta R1, also known as IFNAR1, belongs to the class II cytokine receptor family of proteins. Class II cytokine receptors form heterodimeric receptor complexes that mediate class II cytokine signals. Subunits of the different receptor complexes are shared and serve multiple functions.Functions in general as heterodimer with IFNAR2. Type I interferon binding activates the JAK-STAT signaling cascade, and triggers tyrosine phosphorylation of a number of proteins including JAKs, TYK2, STAT proteins and the IFNR alpha- and beta-subunits themselves.
Product Category	Recombinant Protein
