Function
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. -
Tissue specificity
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. -
Involvement in disease
Defects in CASP8 are the cause of caspase-8 deficiency (CASP8D) [MIM:607271]. CASP8D is a disorder resembling autoimmune lymphoproliferative syndrome (ALPS). It is characterized by lymphadenopathy, splenomegaly, and defective CD95-induced apoptosis of peripheral blood lymphocytes (PBLs). It leads to defects in activation of T-lymphocytes, B-lymphocytes, and natural killer cells leading to immunodeficiency characterized by recurrent sinopulmonary and herpes simplex virus infections and poor responses to immunization. -
Sequence similarities
Belongs to the peptidase C14A family.
Contains 2 DED (death effector) domains. -
Domain
Isoform 9 contains a N-terminal extension that is required for interaction with the BCAP31 complex. -
Post-translational
modificationsGeneration 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.
Phosphorylated upon DNA damage, probably by ATM or ATR. -

All lanes : HRP Anti-Caspase-8 antibody [E7] (ab194145) at 1/5000 dilution
Lane 1 : Wild-type HAP1 whole cell lysate
Lane 2 : CASP8 knockout HAP1 whole cell lysate
Lysates/proteins at 20 µg per lane.
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 55 kDa
Exposure time: 20 minutesab194145 was shown to specifically react with Caspase-8 in wild-type HAP1 cells as signal was lost in CASP8 knockout cells. Wild-type and CASP8 knockout samples were subjected to SDS-PAGE. ab194145 was incubated overnight at 4oC at 1/5000 dilution. Blots were developed with ECL technique.

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 55 kDa
Observed band size: 55 kDa
Exposure time: 20 minutesThis blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab194145 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.
