==Summary==

===Protein Function ===
Caspases (cysteine-aspartic acid protease (caspase) family) are a family of cysteine proteases that have important intracellular roles in inflammation and apoptosis. Activation of caspases ensures that the cellular components are degraded in a controlled manner, carrying out cell death with minimal effect on surrounding tissues. Caspases exist as inactive proenzymes composed of a prodomain, a large protease subunit, and a small protease subunit. Activation of caspases requires proteolytic processing at conserved internal aspartic residues to generate a heterodimeric enzyme consisting of the large and small subunits. 
Caspase-8 activates downstream caspases which are unable to carry out autocatalytic processing and activation. Caspase-8 is designated as an initiator caspase and is believed to sit at the apex of the Fas- or TNF-mediated apoptotic cascade. This protein is involved in the programmed cell death induced by Fas and various apoptotic stimuli. The N-terminal FADD-like death effector domain of this protein suggests that it may interact with Fas-interacting protein FADD. This protein was detected in the insoluble fraction of the affected brain region from Huntington disease patients but not in those from normal controls, which implicated the role in neurodegenerative diseases.
 

===Cys Function & Property===
The catalytic triad in caspase-8 comprises Cys360, His317 and the backbone carbonyl oxygen atom of Arg258, which points towards the Nϵ atom of His317.
