Purity > 85% as determined by SDS-PAGE. MW: 26.5kDa. Partial: 102-280aa. N-terminal 10xHis-tagged. Macaca fascicularis (Crab-eating macaque) (Cynomolgus monkey). Cytokine that binds to TNFRSF6/FAS, a receptor that transduces the apoptotic signal into cells. Involved in cytotoxic T-cell-mediated apoptosis, natural killer cell-mediated apoptosis and in T-cell development. Initiates fratricidal/suicidal activation-induced cell death in antigen-activated T-cells contributing to the termination of immune responses. TNFRSF6/FAS-mediated apoptosis has also a role in the induction of peripheral tolerance. Binds to TNFRSF6B/DcR3, a decoy receptor that blocks apoptosis.Tumor necrosis factor ligand superfamily member 6, soluble form: Induces FAS-mediated activation of NF-kappa-B, initiating non-apoptotic signaling pathways. Can induce apoptosis but does not appear to be essential for this process.FasL intracellular domain: Cytoplasmic form induces gene transcription inhibition.
