caspase-8 is initially synthesized as a single-chain zymogen, procaspase-8, and activated by autocleavage at proteolytic sites Asp126, Asp216, Asp374, and Asp384 after recruitment to DISCs by N-terminal two tandem DEDs of procaspase-8. The proximity-driven dimerization of procaspase-8 is attributable to initiate autocleavage of procaspase-8 involving intra-dimeric and inter-dimeric attack. Dimerized procaspase-8 which achieves enzymatical competency specifically processes one another, while mature caspase-8 can cleave effector caspases and some other substrates. Dramatical conformation changes of the linker region undergo in order to bring cleavage sites, Asp374 and Asp384, to the vicinity of catalytic residue Cys283 from other protomer during dimerization of procaspase-8. Separation of the large and small subunit after intra-dimeric cleavage in the linker region between the large and small subunit renders the linker region between the large subunit and the prodomain of caspase-8 susceptible for the further inter-dimeric cleavage
the C- and N-terminal end, of linker region are released with cleavage at Asp374 and Asp384 before separation of the large and small subunit

Fas ligand, a type II transmembrane protein expressed on the surface of cells, induces apoptotic cell death by binding to its receptor Fas, resulting in recruitment of the Fas-associated death domain protein and caspase 8 zymogens to the receptor and the formation of the death-inducing signalling complex, after which the caspases cascade can be activated. Defects in the Fas/FasL apoptotic signalling pathway provide a survival advantage to cancer cells and may be implicated in tumorigenesis

initial activation of caspase-8 causes degradation of glutaredoxin-1, resulting in S-glutathionylation of Fas at cysteine 294, which subsequently enhances binding of FasL, aggregation of Fas, accumulation of Fas in lipid rafts, DISC assembly, and further activation of caspases, causing a propagation of apoptotic cell death. activation of caspases is required for degradation of glutaredoxin-1 and S-glutathionylation of Fas, engagement of Fas causes a rapid activation of caspase-8. Overexpression of Grx1 prevents increases in S-glutathionylation of Fas and attenuates caspase activation and apoptosis in response to receptor ligation. Cleaved caspase-8 and -3 demonstrate an association between active caspases and Grx1 in cells after ligation of Fas, whereas in control cells, these associations are not observed, regulation, overview

LRRK2-induced neuronal death is caspase-8-dependent. Fas death domain, FADD, recruits caspase-8 to LRRK2. FADD transduces death signals by binding to ligand-activated Fas via its DD and recruiting and activating caspase-8 via its death-effector domain, DED. The Parkinson disease protein leucine-rich repeat kinase 2 transduces death signals via Fas-associated protein with death domain and caspase-8 in a cellular model of neurodegeneration. In primary neuronal culture LRRK2-mediated neurodegeneration is prevented by the functional inhibition of FADD or depletion of caspase-8, two key elements of the extrinsic cell death pathway, overview

caspase-8 is dispensable for B-cell development, but its loss in B cells results in attenuated antibody production upon in vivo viral infection. Important role for caspase-8 in maintaining B-cell survival following stimulation of the Toll-like receptor (TLR)2, -3, and -4. In response to TLR4 stimulation, caspase-8 is recruited to a complex containing IKKalphabeta, and its loss results in delayed NFkappaB nuclear translocation and impaired NFkappaB transcriptional activity.
