A deficiency in caspase-9 largely affects the brain and its development. [27] The effects of having a mutation or deficiency in this caspase compared to others is detrimental. [27] The initiating role caspase-9 plays in apoptosis is the cause for the severe effects seen in those with an atypical caspase-9.
Caspase-3 is a caspase protein that interacts with caspase-8 and caspase-9. It is encoded by the CASP3 gene. ... Apoptosis & Caspase 3 – The Proteolysis Map-animation

CARDs were originally characterized based on their involvement in the regulation of caspase activation and apoptosis. [2] The basic six-helix structure of the domain appears to be conserved as far back as the ced-3 and ced-4 genes in C. elegans, the organism in which several components of the apoptotic machinery were first characterized.
During apoptosis, the apoptotic effector caspase, caspase-3, cleaves ICAD and thus causes CAD to become activated. [7] A nucleosome, consisting of DNA (grey) wrapped around a histone tetramer (coloured). In apoptotic DNA fragmentation, the DNA is cleaved in the internucleosomal linker region, which is the part of the DNA not wrapped around the ...
Caspase-3 is activated in the apoptotic cell. [9] Caspase-3 activation is a cell requirement during early stages of the skeletal myoblast differentiation. Its catalytic site involves sulfohydryl group of Cys-285 and the imidazole ring of its His-237. The caspase-3 His-237 stabilizes the target Aspartate causing the break of the association of ...
The precise mechanism for this reaction is still debated though work published by Guy Salvesen suggests that the apoptosome may induce caspase-9 dimerization and subsequent autocatalysis. [9] Activated caspase-9 stimulates the subsequent caspase cascade that commits the cell to apoptosis. [citation needed]
