GITR Ligand/TNFSF18 (C-6His) (recombinant cynomolgus)

Protein Construction: Recombinant Cynomolgus TNF Superfamily Member 18 is produced by our Mammalian expression system and the target gene encoding Glu74-Ser199 is expressed with a 6His tag at the C-terminus. Sequence: Glu74-Ser199. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 15-20 kDa. Protein function: TNFSF18 is a single-pass type II membrane protein. It is expressed at high levels in the small intestine, ovary, testis, kidney and endothelial cells. TNFSF18 cytokine binds to TNFRSF18/AITR/GITR. It regulates T-cell responses, and functions as costimulator and lower the threshold for T-cell activation and T-cell proliferation. It is Important for interactions between activated T-lymphocytes and endothelial cells and Promotes leukocyte adhesion to endothelial cells. TNFSF18 mediates activation of NF-kappa-B. As Triggers increased phosphorylation of STAT1 and up-regulates expression of VCAM1 and ICAM1. It also regulates migration of monocytes from the splenic reservoir to sites of inflammation.
