GMP IFN-gamma Protein, Human

IFN-gamma Protein is a dimeric soluble cytokine. It exerts antibacterial, antiviral and antitumor effects through JAK-STAT, mTOR, MAPK and PI3K/AKT signaling pathways. GMP IFN-gamma Protein, Human is the recombinant human-derived IFN-gamma protein, expressed by E. coli , with tag free. The total length of GMP IFN-gamma Protein, Human is 143 a.a., with molecular weight of ~16.7 kDa.

IFN-gamma is a dimeric soluble cytokine that is the only member of type II interferon IFN-gamma is produced by immune cells T cells and NK cells and plays an important role in antimicrobial, antiviral and anti-tumor responses by activating effector immune cells and enhancing antigen presentation. IFN-gamma influences gene regulation by interacting with its receptor IFNGR1 through the JAK-STAT pathway, and can also trigger mTOR, MAPK, and PI3K/AKT signaling pathways. IFN-gamma plays a role in the Class I antigen presentation pathway by inducing the substitution of the catalytic proteasome subunit for the immune proteasome subunit. IFN-gamma upregulates the MHC II complex on the cell surface by promoting the expression of several key molecules such as pepsin B/CTSB, H/CTSH, and L/CTSL. IFN-gamma is involved in the regulation of hematopoietic stem cells under developmental and homeostasis conditions by influencing the development, quiescence and differentiation of hematopoietic stem cells^{[1][2][3][4][5]}.
