TRAIL (TNFSF10) was identified as a novel type II transmembrane protein of the TNF family, with its C-terminal extracellular domain forming a homotrimeric structure. Both full-length cell-surface TRAIL and picomolar concentrations of soluble TRAIL rapidly induce apoptosis in a wide variety of transformed cell lines. The TRAIL gene is located on chromosome 3q26. |

Apo-2L (TRAIL/TNFSF10) is a 281-amino acid type II transmembrane protein whose C-terminal extracellular region forms a homotrimeric subunit structure. Soluble Apo-2L induces apoptosis in lymphoid and non-lymphoid tumor cell lines through a receptor distinct from Fas/Apo-1 and TNF receptors, as soluble Fas and TNF receptors do not inhibit its activity. |

DR4 (TRAIL-R1), identified as the first receptor for TRAIL, is a member of the TNF-receptor family containing a cytoplasmic death domain capable of engaging the apoptotic machinery. DR4 could not use FADD to transmit the death signal (unlike Fas, TNFR-1, and DR3), suggesting use of distinct proximal signaling machinery. DR4 did not activate NF-κB in the system studied. |

TRAIL-R4 retains an incomplete death domain (one-third of consensus motif) and activates NF-κB similarly to TRAIL-R1/R2, but cannot induce apoptosis. Transient overexpression of TRAIL-R4 in TRAIL-sensitive cells conferred complete protection from TRAIL-mediated killing.

Three elongated DR5 receptors bind in long crevices between pairs of monomers of the trimeric ligand. The binding interface is divided into two distinct patches (near the membrane-proximal and membrane-distal ends), both containing residues critical for high-affinity binding. Comparison to the lymphotoxin-receptor complex revealed general principles of binding in the TNF receptor superfamily. |

FADD/MORT1 and caspase-8 are recruited to both TRAIL-R1 and TRAIL-R2 in a ligand-dependent manner to form the TRAIL death-inducing signaling complex (DISC). FADD/MORT1 and caspase-8 are recruited to the two TRAIL receptors independently of each other. FADD- and caspase-8-deficient Jurkat cells expressing only TRAIL-R2 were resistant to TRAIL-induced apoptosis, establishing that both proteins are essential for TRAIL-R2-mediated apoptosis. |
