DcR2 ( decoy receptor 2), also known as CD264, TRAILR4, and TRUNDD, is a Single-pass type I transmembrane protein of the TNF receptor superfamily (TNFRSF10D).  DcR2 contains an extracellular TRAIL-binding domain with 3 TNFR-cysteine repeats, a transmembrane domain, and a truncated cytoplasmic death domain. Therefore DcR2 does not induce apoptosis, and may play an inhibitory role in TRAIL-induced cell apoptosis. DcR2 is widely expressed, in particular in fetal kidney, lung and liver, and in adult testis and liver. It is also expressed in peripheral blood leukocytes, colon and small intestine, ovary, prostate, thymus, spleen, pancreas, kidney, lung, placenta and heart. Aberrant methylation of DcR2 is frequent in multiple tumor types. Overexpression of TRAIL R4 can protect cells bearing TRAILR1 and/or TRAILR2 from TRAIL­mediated apoptosis. The human soluble DcR2-Fc chimera neutralizes the ability of TRAIL to induce apoptosis.
