Human TRAIL R2, also called DR5 and TRICK 2 is a type 1, TNF R family, membrane protein which is a receptor for TRAIL (APO2 ligand). In the new TNF superfamily nomenclature, TRAIL R2 is referred to as TNFRSF10B. TRAIL R2 cDNA encodes a 440 amino acid residue precursor protein containing extracellular cysteine-rich domains, a transmembrane domain and a cytoplasmic death domain. Among TNF receptor family proteins, TRAIL R2 is most closely related to TRAIL R1/DR4, sharing 55% amino acid sequence identity. Binding of trimeric TRAIL to TRAIL R2 induces apoptosis. The induction of apoptosis likely requires oligomerization of the receptor. The human TRAIL R2/Fc chimera neutralizes the ability of TRAIL to induce apoptosis. Besides TRAIL R2, an additional TRAIL R1/DR4, which tranduces apoptosis signaling, and two TRAIL decoy receptors, which antagonize TRAIL-induced apoptosis, have been reported.

Human TRAIL R2/TNFRSF10B Antibody Induces Apoptosis of Jurkat Cells.
Human TRAIL R2/TNFRSF10B Monoclonal Antibody induces apoptosis of the Jurkat human acute T cell leukemia cell line in a dose-dependent manner, as measured by Resazurin (Catalog # AR002). The ED50 for this effect is typically 2-12 ng/mL.
Detection of Human TRAILR2/TNFRSF10B by Western Blot
Cleavage of FRET probe is indicative of caspase activation.Cells were treated with (A) 0–300 ng/ml TRAIL for 2.5 hours or (B) 0–50 µg/ml anti-DR5 antibody for 20 h. The resultant cells were analyzed by western blotting using antibodies specific to caspase 3 (C3), caspase 8 (C8), and CFP/YFP.

MB231_CFP-YFP cells retain sensitivity to TRAIL and anti-DR5 antibody.(A) Parental MB231 (filled black) and MB231_CFP-YFP (open clear) cells were treated with TRAIL (0–100 ng/ml) for 2.5 h or anti-DR5 antibody (0–200 µg/ml) for 20 h, at the indicated concentrations. Cell viability was determined by MTT assay. (B) Cells were treated as in A and analyzed for apoptosis by flow cytometry after staining with Annexin-V-APC and propidium iodide (PI). p-values were determined using a Student’s t-test. EC50 values were determined using nonlinear curve fitting as described in the Materials and Methods section. For each EC50 value, 95% confidence intervals reflecting the statistical accuracy are reported in Table 1.

Cell-based FRET biosensor provides a quantifiable response to treatments of death receptor targeted cancer therapies.MB231_CFP-YFP cells were treated with (A) 0–300 ng/ml TRAIL for 2.5 h and (B) 0–100 µg/ml anti-DR5 antibody for 20 h. FRET was calculated and is represented using bar graphs on the left side of the panel. EC50 values were determined by nonlinear curve fitting to normalized FRET values plotted against the log values of TRAIL and anti-DR5 antibody concentration in molar (right side of the panel). (C) Confocal microscopy images showing changes in FRET in MB231_CFP-YFP cells treated with 0–25 ng/ml TRAIL for 2.5 h. A pronounced shift from YFP acceptor emission (yellow) to CFP donor emission (cyan) can be observed for cells treated with increasing concentration of TRAIL, with an excitation setting = 458 nm. Statistical analysis was performed as in Fig. 1 and 2.
