CC   -!- FUNCTION: Involved in the activation cascade of caspases
CC       responsible for apoptosis execution. At the onset of apoptosis it
CC       proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a
CC       '216-Asp-|-Gly-217' bond. Cleaves and activates sterol regulatory
CC       element binding proteins (SREBPs) between the basic helix-loop-
CC       helix leucine zipper domain and the membrane attachment domain.
CC       Cleaves and activates caspase-6, -7 and -9. Involved in the
CC       cleavage of huntingtin (By similarity).
CC   -!- CATALYTIC ACTIVITY: Strict requirement for an Asp residue at
CC       positions P1 and P4. It has a preferred cleavage sequence of Asp-
CC       Xaa-Xaa-Asp-|- with a hydrophobic amino-acid residue at P2 and a
CC       hydrophilic amino-acid residue at P3, although Val or Ala are also
CC       accepted at this position.
CC   -!- SUBUNIT: Heterotetramer that consists of two anti-parallel
CC       arranged heterodimers, each one formed by a 17 kDa (p17) and a 12
CC       kDa (p12) subunit (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- PTM: Cleavage by granzyme B, caspase-6, caspase-8 and caspase-10
CC       generates the two active subunits. Additional processing of the
CC       propeptides is likely due to the autocatalytic activity of the
CC       activated protease. Active heterodimers between the small subunit
CC       of caspase-7 protease and the large subunit of caspase-3 also
CC       occur and vice versa (By similarity).
CC   -!- PTM: S-nitrosylated on its catalytic site cysteine in unstimulated
CC       human cell lines and denitrosylated upon activation of the Fas
CC       apoptotic pathway, associated with an increase in intracellular
CC       caspase activity. Fas therefore activates caspase-3 not only by
CC       inducing the cleavage of the caspase zymogen to its active
CC       subunits, but also by stimulating the denitrosylation of its
CC       active site thiol (By similarity).
CC   -!- SIMILARITY: Belongs to the peptidase C14A family.
