Cytokine that binds to TNFRSF6/FAS, a receptor that transduces the apoptotic signal into cells. May be involved in cytotoxic T-cell mediated apoptosis and in T-cell development. TNFRSF6/FAS-mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. Binding to the decoy receptor TNFRSF6B/DcR3 modulates its effects.
Specificity
Natural and recombinant Human Tumor necrosis factor ligand superfamily member 6
Subcellular Location
Cell membrane Single-pass type II membrane protein Secreted Cytoplasmic vesicle lumen Lysosome lumen May be released into the extracellular fluid, probably by cleavage form the cell surface. Is internalized into multivesicular bodies of secretory lysosomes after phosphorylation by FGR and monoubiquitination.
