ターゲット情報

  • 機能
    Most upstream protease of the activation cascade of caspases responsible for the TNFRSF6/FAS mediated and TNFRSF1A induced cell death. Binding to the adapter molecule FADD recruits it to either receptor. The resulting aggregate called death-inducing signaling complex (DISC) performs CASP8 proteolytic activation. The active dimeric enzyme is then liberated from the DISC and free to activate downstream apoptotic proteases. Proteolytic fragments of the N-terminal propeptide (termed CAP3, CAP5 and CAP6) are likely retained in the DISC. Cleaves and activates CASP3, CASP4, CASP6, CASP7, CASP9 and CASP10. May participate in the GZMB apoptotic pathways. Cleaves ADPRT. Hydrolyzes the small-molecule substrate, Ac-Asp-Glu-Val-Asp-
    -AMC. Likely target for the cowpox virus CRMA death inhibitory protein. Isoform 5, isoform 6, isoform 7 and isoform 8 lack the catalytic site and may interfere with the pro-apoptotic activity of the complex.
  • 組織特異性
    Isoform 1, isoform 5 and isoform 7 are expressed in a wide variety of tissues. Highest expression in peripheral blood leukocytes, spleen, thymus and liver. Barely detectable in brain, testis and skeletal muscle.
  • 関連疾患
    Caspase-8 deficiency
  • 配列類似性
    Belongs to the peptidase C14A family.
    Contains 2 DED (death effector) domains.
  • ドメイン
    Isoform 9 contains a N-terminal extension that is required for interaction with the BCAP31 complex.
  • 翻訳後修飾
    Generation of the subunits requires association with the death-inducing signaling complex (DISC), whereas additional processing is likely due to the autocatalytic activity of the activated protease. GZMB and CASP10 can be involved in these processing events.
    Phosphorylation on Ser-387 during mitosis by CDK1 inhibits activation by proteolysis and prevents apoptosis. This phosphorylation occurs in cancer cell lines, as well as in primary breast tissues and lymphocytes.

    Thank you for your explanation. In the case of using a mouse Ab in IHC for mouse tissues, one can label the primary Ab with Biotin to avoid erroneous results. Your antibody is the only one I can found that only recognize cleaved caspase-8 fragment. So ...

    Thank you for your message. As it has not been tested yet with mouse tissue, we cannot provide any guarantees, but we would be very interested to hear how it works out for you if you do decide to try it. If you have any more questions, please do contac...

    Hi, From reading some of the earlier enquiries, I understand that this caspase-8 Ab (C502S) only recongnizes human p10 but not the proform of caspase-8. I am looking for a caspase-8 antibody that only recongnizes activated caspase-8 in tissue section b...

    Ab2553 has only been tested so far for cross-reactivity with human and tested in Western blotting and IP. I would not recommend this antibody to try with mouse samples in IHC - For immunohistochemistry, the primary antibody should be raised in a specie...

    Do these antibodies recognize both the active and the inactive forms of Caspase or only the active form? Could you please confirm it?

    Thank you for your enquiry. This antibody recognizes only the active form.

    I want to confirm that the sequence I am using is actually from human and not mouse caspase as you seem to think, in which case would you mind double checking that our sequences are not the same? Thanks

    The information I have on file and can release is that the immunogen is a 12 a.a peptide corresponding to the N-terminus of the p10 subunit of human caspase-8. I cannot release the exact sequence, but if customer is working on caspases, he or she can e...

    Thank you for your previous information on this enquiry. The customer understands that you m,ay not wish to reveal your sequence used but wondered if you tell her if her sequence (LSSPQTRYIPDE) is not the same. thanks

    The customer's sequence seems to be derived from mouse caspase-8. ab2553 utilizes the sequence derived from human. There are a few amino acids are different between human and mouse caspase-8.

    Thank you very much for the information. I have just placed an order for this Ab via my accounts department. Please could you tell me the sequence of the immunogen used to produce the Ab.

    The immunogen is the synthetic peptide corresponding to residues mapping at the N-terminus of the p10 fragment of caspase-8. Gloria

    Caspase 8 antibody (ab2553) clone C502S. Does this Ab detect the p10 only or does it also detect the proform and the other cleaved fragments? I am interested in an Ab which only detects p10 .

    Yes, the antibody only detects p10 fragment of the cleaved caspase-8.
