The structure of Death Receptor 4 (DR4) in complex with TNF-related apoptosis-inducing ligand (TRAIL) has been determined at 3 Å resolution and compared with those of previously determined DR5-TRAIL complexes. Consistent with the high sequence similarity between DR4 and DR5, the overall arrangement of the DR4-TRAIL complex does not differ substantially from that of the DR5-TRAIL complex. However, subtle differences are apparent. In addition, solution interaction studies were carried out that show differences in the thermodynamics of binding DR4 or DR5 with TRAIL.
