  • 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.
  • Involvement in disease
    Familial hibernian fever
    Multiple sclerosis 5
  • Sequence similarities
    Contains 1 death domain.
    Contains 4 TNFR-Cys repeats.
  • Domain
    The domain that induces A-SMASE is probably identical to the death domain. The N-SMASE activation domain (NSD) is both necessary and sufficient for activation of N-SMASE.
    Both the cytoplasmic membrane-proximal region and the C-terminal region containing the death domain are involved in the interaction with TRPC4AP.
  • Post-translational
    The soluble form is produced from the membrane form by proteolytic processing.
  • Cellular localization
    Cell membrane. Golgi apparatus membrane. Secreted. A secreted form is produced through proteolytic processing and Secreted. Lacks a Golgi-retention motif, is not membrane bound and therefore is secreted.

Thank you for your enquiry regardingab19139 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody. After reading through the detailed protocol you kindly forwarded to Abcam, I would like to make the following comments/suggestions: 1) Secondary antibody - detection: Does the detection system work fine? Have you used it successfully with another primary antibody? Is the HRP still active? 2) Loading: Has the customer tried loading more total protein (HEK293) onto the gel 25-30 ug per lane to see if the signal is getting stronger or not. I hope this will be useful for you. Should you still have any problem with this antibody after following these suggestions, then please do not hesitate to contact our Technical Department again.
