  • 产品描述:

    Human TNFRSF18 amino acids Gln26-Pro162, with a C-terminal hFc-tag as well as an N-terminal linker, were expressed in mammalian cells. The product is the recombinant human TNFRSF18 protein. The SDS-PAGE analysis determined its purity greater than 92% and showed a molecular weight band of about 45 kDa on the gel. It contains low levels of endotoxin, less than 1.0 EU/ug measured by the LAL method. Functional ELISA and LSPR assay of this TNFRSF18 protein showed that it is an active protein. This protein is in stock so that it will reach your lab bench faster.

    TNFRSF18, also known as GITR, is expressed on Tregs and some activated immune cells, including effector T lymphocytes, NK cells, and neutrophils. TNFRSF18 ligation with effector T cells can elicit a positive costimulatory signal and promote T cell activation and proliferation, while evocation of TNFRSF18 on Tregs blocks their inhibitory functions. Studies have shown that TNFRSF18/TNFSF18 signaling is implicated in the pathogenesis of inflammation, autoimmune diseases, and tumor.

  • 功能:
    Receptor for TNFSF18. Seems to be involved in interactions between activated T-lymphocytes and endothelial cells and in the regulation of T-cell receptor-mediated cell death. Mediated NF-kappa-B activation via the TRAF2/NIK pathway.
