Description
This gene is a member of the tumor necrosis factor superfamily. The primary function of the encoded transmembrane protein is the induction of apoptosis triggered by binding to FAS. The FAS/FASLG signaling pathway is essential for immune system regulation, including activation-induced cell death (AICD) of T cells and cytotoxic T lymphocyte induced cell death. It has also been implicated in the progression of several cancers. Defects in this gene may be related to some cases of systemic lupus erythematosus (SLE). Alternatively spliced transcript variants have been described.
Bio-activity
Measured by its ability to induce apoptosis of Jurkat human acute T cell leukemia cells. The ED50 for this effect is 0.25-1.5 μg/mL in the presence of 10 μg/mL of a cross-linking antibody Mouse Anti-polyHistidine Monoclonal Antibody. This soluble Recombinant Mouse Fas Ligand/TNFSF6 has weak cytotoxic activity. It has no effects on A20 mouse B cell lymphoma cells which express mouse Fas. This is one of multiple forms available for this protein. Check R&D Systems' website, www.RnDSystems.com, for a complete listing of the products.
