Background

  • Function

    Thiol protease that plays a key role in programmed cell death by acting as a molecular switch for apoptosis, necroptosis and pyroptosis, and is required to prevent tissue damage during embryonic development and adulthood (PubMed:23516580, PubMed:35338844, PubMed:35446120, PubMed:8681376, PubMed:8681377, PubMed:8962078, PubMed:9006941, PubMed:9184224). Initiator protease that induces extrinsic apoptosis by mediating cleavage and activation of effector caspases responsible for FAS/CD95-mediated and TNFRSF1A-induced cell death (PubMed:23516580, PubMed:35338844, PubMed:35446120, PubMed:8681376, PubMed:8681377, PubMed:8962078, PubMed:9006941, PubMed:9184224). Cleaves and activates effector caspases CASP3, CASP4, CASP6, CASP7, CASP9 and CASP10 (PubMed:16916640, PubMed:8962078, PubMed:9006941). Binding to the adapter molecule FADD recruits it to either receptor FAS/TNFRSF6 or TNFRSF1A (PubMed:8681376, PubMed:8681377). The resulting aggregate called the death-inducing signaling complex (DISC) performs CASP8 proteolytic activation (PubMed:9184224). The active dimeric enzyme is then liberated from the DISC and free to activate downstream apoptotic proteases (PubMed:9184224). Proteolytic fragments of the N-terminal propeptide (termed CAP3, CAP5 and CAP6) are likely retained in the DISC (PubMed:9184224). In addition to extrinsic apoptosis, also acts as a negative regulator of necroptosis: acts by cleaving RIPK1 at 'Asp-324', which is crucial to inhibit RIPK1 kinase activity, limiting TNF-induced apoptosis, necroptosis and inflammatory response (PubMed:31827280, PubMed:31827281). Also able to initiate pyroptosis by mediating cleavage and activation of gasdermin-C and -D (GSDMC and GSDMD, respectively): gasdermin cleavage promotes release of the N-terminal moiety that binds to membranes and forms pores, triggering pyroptosis (PubMed:32929201, PubMed:34012073). Initiates pyroptosis following inactivation of MAP3K7/TAK1 (By similarity). Also acts as a regulator of innate immunity by mediating cleavage and inactivation of N4BP1 downstream of TLR3 or TLR4, thereby promoting cytokine production (By similarity). May participate in the Granzyme B (GZMB) cell death pathways (PubMed:8755496). Cleaves PARP1 and PARP2 (PubMed:8681376). Independent of its protease activity, promotes cell migration following phosphorylation at Tyr-380 (PubMed:18216014, PubMed:27109099); Lacks the catalytic site and may interfere with the pro-apoptotic activity of the complex; Lacks the catalytic site and may interfere with the pro-apoptotic activity of the complex; Lacks the catalytic site and may interfere with the pro-apoptotic activity of the complex (Probable). Acts as an inhibitor of the caspase cascade (PubMed:12010809); Lacks the catalytic site and may interfere with the pro-apoptotic activity of the complex

    Generation of the p10 and p18 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 (PubMed:20937773). Phosphorylation on Tyr-380 by SRC is mediated by interaction with the SRC SH2 domain and does not affect dimerization or recruitment to the death-inducing signaling complex (DISC) but negatively regulates DISC-mediated processing and activation of CASP8, down-regulating its proapoptotic function (PubMed:16619028, PubMed:27109099). Phosphorylation on Tyr-380 also enhances localization to lamellipodia in migrating cells (PubMed:18216014);(Microbial infection) ADP-riboxanation by C.violaceum CopC blocks CASP8 processing, preventing CASP8 activation and ability to mediate extrinsic apoptosis;(Microbial infection) Proteolytically cleaved by the cowpox virus CRMA death inhibitory protein

  • Subunit

    Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 18 kDa (p18) and a 10 kDa (p10) subunit (PubMed:10508784). Component of the death-induced signaling complex (DISC) composed of cell surface receptor FAS/CD95 or TNFRSF1A, adapter protein FADD and the CASP8 protease; recruitment of CASP8 to the complex is required for processing of CASP8 into the p18 and p10 subunits (PubMed:8681376, PubMed:8681377, PubMed:9184224). Component of the AIM2 PANoptosome complex, a multiprotein complex that drives inflammatory cell death (PANoptosis) (By similarity). Interacts with CFLAR and PEA15 (PubMed:10442631). Interacts with TNFAIP8L2 (By similarity). Interacts with CASP8AP2 (PubMed:16378960). Interacts with RFFL and RNF34; negatively regulate CASP8 through proteasomal degradation (PubMed:15069192). Interacts with NOL3; decreases CASP8 activity in a mitochondria localization- and phosphorylation-dependent manner and this interaction is dissociated by calcium (PubMed:15509781). Interacts with UBR2ca (PubMed:28602583). Interacts with RIPK1 (By similarity). Interacts with stimulated TNFRSF10B; this interaction is followed by CASP8 proteolytic cleavage and activation (PubMed:18846110). Interacts (phosphorylated on Tyr-380) with PIK3R1 (PubMed:27109099)
