Death receptor 4 (DR4), also known asTRAIL receptor 1 (TRAILR1) andtumor necrosis factor receptor superfamily member 10A (TNFRSF10A), is acell surface receptor of theTNF-receptor superfamily that bindsTRAIL and mediatesapoptosis.[5][6]
The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is activated by tumor necrosis factor-related apoptosis inducing ligand (TNFSF10/TRAIL), and thus transduces cell death signal and induces cell apoptosis.[7]
Studies with FADD-deficient mice suggested thatFADD, a death domain containing adaptor protein, is required for the apoptosis mediated by this protein.[8]
TNFRSF10A has been shown tointeract withDAP3.[9]
