Scientific background: |
TNFRSF10A (Tumor Necrosis Factor Receptor Subfamily Member 10A), also known as APO2, DR4 or TRAILR1, is a protein that in humans is encoded by the TNFRSF10A gene. The protein encoded by this gene is a member of the TNF-receptor superfamily. By analysis of radiation hybrids, Marsters et al. (1997) mapped the DR4 gene to 8p21. The TRAIL receptor DR5, and 2 decoy receptors for TRAIL, DCR1, and DCR2, are located in the same region, suggesting that these receptors arose from recent gene duplication events. Pan et al. (1997) found that, as with FAS, TNFR1, and DR3, overexpression of DR4 induced apoptosis. However, unlike the other 3 death receptors, DR4 did not use FADD to transmit the death signal, suggesting the use of distinct proximal signaling machinery. |
