Anti-TNF p55 Receptor

This antiserum has been heated to 56°C for 30 minutes.  The antiserum is directed against the extracellular domain of the cell bound human TNFRp55.  In general, this antibody also detects primate sTNFRp55.  The antibody does not recognize human sTNFRp75.  In ELISA formats and other immunoreactive assays, this antibody will detect the extracellular domain of the TNFRp55 found in human body fluids, particularly in the circulation, urine and supernatants of cells and synovial fluid. Protein function: Receptor for TNFSF2/TNF-alpha and homotrimeric TNFSF1/lymphotoxin-alpha. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate- specific cysteine proteases) mediating apoptosis. Contributes to the induction of non-cytocidal TNF effects including anti-viral state and activation of the acid sphingomyelinase. [The UniProt Consortium]
