Recombinant Mouse TRAIL R2/TNFRSF10B Fc Chimera Protein, CF

Mouse TRAIL R2, also called DR5, TRICK 2, TNFRSF10B, and MK is a type 1 TNF R superfamily, membrane protein which is a receptor for TRAIL (APO2 ligand). Mouse TRAIL R2 cDNA encodes a 381 amino acid residue precursor protein containing an extracellular cysteine-rich domain, a transmembrane domain and a cytoplasmic death domain. Human and mouse TRAIL R2 share 49% amino acid sequence similarity. The death domains of human TRAIL R1 and TRAIL R2 share high homology with the death domain of mouse TRAIL R2, 76% and 79%, respectively. Binding of trimeric TRAIL to TRAIL R2 induces apoptosis. The induction of apoptosis likely requires oligomerization of the receptor. The mouse TRAIL R2/Fc chimera neutralizes the ability of rhTRAIL to induce apoptosis. Besides the death domain containing receptors TRAIL R2 and TRAIL R1/DR4, three TRAIL decoy receptors, TRAIL R3/DcR1, TRAIL R4/DcR2, and OPG, have been reported.
