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. Homotrimer (Probable). Interacts with ARHGAP9, BAIAP2L1, BTK, CACNB3, CACNB4, CRK, DLG2, DNMBP, DOCK4, EPS8L3, FGR, FYB, FYN, HCK, ITK, ITSN2, KALRN, LYN, MACC1, MIA, MPP4, MYO15A, NCF1, NCK1, NCK2, NCKIPSD, OSTF1, PIK3R1, PSTPIP1, RIMBP3C, SAMSN1, SH3GL3, SH3PXD2B, SH3PXD2A, SH3RF2, SKAP2, SNX33, SNX9, SORBS3, SPTA1, SRC, SRGAP1, SRGAP2, SRGAP3, TEC, TJP3 and YES1. Belongs to the tumor necrosis factor family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
