Enzyme Function 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:18455983, PubMed:30361383, PubMed:30381458, PubMed:31511692, PubMed:31748744, PubMed:33397971). Initiator protease that induces extrinsic apoptosis by mediating cleavage and activation of effector caspases responsible for the TNFRSF6/FAS mediated and TNFRSF1A induced cell death (PubMed:9654089, PubMed:9837723, PubMed:24813849, PubMed:24813850). Cleaves and activates effector caspases CASP3, CASP4, CASP6, CASP7, CASP9 and CASP10 (By similarity). Binding to the adapter molecule FADD recruits it to either receptor TNFRSF6/FAS mediated or TNFRSF1A (PubMed:29440439). The resulting aggregate called death-inducing signaling complex (DISC) performs CASP8 proteolytic activation (By similarity). The active dimeric enzyme is then liberated from the DISC and free to activate downstream apoptotic proteases (By similarity). Proteolytic fragments of the N-terminal propeptide (termed CAP3, CAP5 and CAP6) are likely retained in the DISC (By similarity). In addition to extrinsic apoptosis, also acts as a negative regulator of necroptosis: acts by cleaving RIPK1 at 'Asp-325', which is crucial to inhibit RIPK1 kinase activity, limiting TNF-induced apoptosis, necroptosis and inflammatory response (PubMed:31511692). Also able to initiate pyroptosis by mediating cleavage and activation of gasdermin-D (GSDMD): GSDMD cleavage promoting release of the N-terminal moiety (Gasdermin-D, N-terminal) that binds to membranes and forms pores, triggering pyroptosis (PubMed:30361383, PubMed:30381458). Initiates pyroptosis following inactivation of MAP3K7/TAK1 (PubMed:30361383, PubMed:30381458). Also acts as a regulator of innate immunity by mediating cleavage and inactivation of N4BP1 downstream of TLR3 or TLR4, thereby promoting cytokine production (PubMed:32971525). May participate in the Granzyme B (GZMB) cell death pathways (By similarity). Cleaves PARP1 (By similarity). {ECO:0000250|UniProtKB:Q14790, ECO:0000269|PubMed:18455983, ECO:0000269|PubMed:24813849, ECO:0000269|PubMed:24813850, ECO:0000269|PubMed:29440439, ECO:0000269|PubMed:30361383, ECO:0000269|PubMed:30381458, ECO:0000269|PubMed:31511692, ECO:0000269|PubMed:31748744, ECO:0000269|PubMed:32971525, ECO:0000269|PubMed:33397971, ECO:0000269|PubMed:9654089, ECO:0000269|PubMed:9837723}.

Post Translational Modification PTM: 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 (PubMed:31511692). GZMB and CASP10 can be involved in these processing events (By similarity). {ECO:0000250|UniProtKB:Q14790, ECO:0000269|PubMed:31511692}.; PTM: (Microbial infection) Proteolytically cleaved by the cowpox virus CRMA death inhibitory protein. {ECO:0000269|PubMed:9837723}.; PTM: Phosphorylation on Ser-389 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 (By similarity). {ECO:0000250|UniProtKB:Q14790}.
