NCIt definition : Activated caspase-3 (249 aa, 29 kDa) is encoded by the human CASP3 gene. This protein
plays a role in the promotion of apoptosis.;
NCIt note : Denitrosylation of the active site thiol of caspase-3 is induced by the Fas-dependent
apoptotic pathway and can also stimulate autocatalytic activity. (UniProt); Cleavage of caspase-3 by granzyme B, caspase-6, caspase-8 and caspase-10 generates
the two active subunits p17 and p12. Additional processing of caspase-3 propeptides
is likely due to the autocatalytic activity of the activated protease. (UniProt); Active heterodimers between the small subunit of caspase-7 protease and the large
subunit of caspase-3 and vice versa, also occur. (UniProt);
