Death receptor 5
Death receptor 5, also known as TRAIL receptor 2 and tumor necrosis factor receptor superfamily member 10B, is a cell [surface receptor] of the TNF-receptor superfamily that binds TRAIL and mediates apoptosis.
Function
The protein encoded by this gene is a member of the TNF-receptor superfamily, and contains an intracellular death domain. This receptor can be activated by tumor necrosis factor-related apoptosis inducing ligand, and transduces apoptosis signal. Mice have a homologous gene, tnfrsf10b, that has been essential in the elucidation of the function of this gene in humans. Studies with FADD-deficient mice suggested that FADD, a death domain containing Signal transducing [adaptor protein|adaptor protein], is required for the apoptosis mediated by this protein.Interactions
DR5 has been shown to interact with:- Caspase 8,
- Caspase 10,
- FADD, and
- TRAIL.
Cancer therapy
Luminescent iridium complex-peptide hybrids, serving as TRAIL mimics, have been designed, which target the death receptors DR4 and DR5 on cancer cells and induce their apoptosis.
