IFN-gamma R1/CD119, Human (HEK293, hFc)

IFN-gamma R1 (CD119), one of the subunit of IFN-gamma receptor, is a receptor for IFN-gamma. IFN-gamma R1 forms the functional receptor with IFN-gamma R2. Upon binding with IFN-gamma, IFN-gamma R1 and IFN-gamma R2 oligomerize and transphosphorylate[1]. Then, JAK1 and JAK2 are phosphorylated and activated, and STAT1 is recruited to the receptor complex. Phosphorylated STAT1 translocates to the nucleus, where it regulates the expression of IFN-responsive genes (e.g. CD54) [2]. IFN-gamma R1/CD119 Protein, Human (HEK293, hFc) is a recombinant human IFN-gamma R1 (E18-G245) with C-terminal hFc tag, which is produced in HEK293 cells.
