Related Product Information for TRAIL active protein

TRAIL, also called Apo2L, is a member of the tumor necrosis factor family (TNF). In contrast to other family members such as TNFa/TNFR1 and FasL/Fas, TRAIL and its receptors DR4 and DR5 are widely expressed in many human tissues. TRAIL activates rapid apoptosis in many transformed cell lines but not in normal tissues, even though TRAIL and its receptors DR4 and DR5 are expressed on both cell  types. A glycophospholipid-anchored cell surface protein designated decoy receptor 1 (DcR1 or TRID) acts as a decoy to inhibit TRAIL signaling. Thus, TRAIL and its signaling pathways may have direct applications in selective tumor cell death and cancer research.

NCBI Description

The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This protein preferentially induces apoptosis in transformed and tumor cells, but does not appear to kill normal cells although it is expressed at a significant level in most normal tissues. This protein binds to several members of TNF receptor superfamily including TNFRSF10A/TRAILR1, TNFRSF10B/TRAILR2, TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4, and possibly also to TNFRSF11B/OPG. The activity of this protein may be modulated by binding to the decoy receptors TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4, and TNFRSF11B/OPG that cannot induce apoptosis. The binding of this protein to its receptors has been shown to trigger the activation of MAPK8/JNK, caspase 8, and caspase 3. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]
