TRAIL-R2 (DR5) Proteins

Protein Information

DR5 (Apo2, TRAIL-R2, TRICK2, KILLER) is a recently identified death domain containing receptor for TRAIL, which mediates TRAIL induced apoptosis. DR5 is a member of the TNF-receptor superfamily, and contains an intracellular death domain. DR5 can be activated by tumor necrosis factor-related apoptosis inducing ligand (TNFSF10/TRAIL/APO-2L), and transduces an apoptosis signal. Studies with FADD-deficient mice suggested that FADD, a death domain containing adaptor protein, is required for the apoptosis mediated by DR5. Two transcript variants encoding different isoforms of DR5 and one non-coding transcript have been found. Overexpression of DR5 induces apoptosis and activates NF-kappa-B. DR5 is expressed in a number of cell types, and to particularly high levels in lymphocytes and spleen. Diseases associated with DR5 dysfunction include squamous cell carcinoma, and diffuse infiltrative lymphocytosis syndrome.
