Purity > 90% as determined by SDS-PAGE. MW: 43.9kDa. Extracellular Domain: 18-262. N-terminal 6xHis-SUMO-tagged. Mus musculus (Mouse). May play a role in the immune syst processes. Protects cells from FAS-, TNF alpha- and FADD-induced apoptosis without increasing expression of the inhibitors of apoptosis BCL2 and BCLXL. Ses to activate an inhibitory pathway that prevents CASP8 activation following FAS stimulation, rather than blocking apoptotic signals downstream. May inhibit FAS-induced apoptosis by preventing CASP8 processing through CFLAR up-regulation.
