CC -!- FUNCTION: Involved in the activation cascade of caspases responsible
CC for apoptosis execution. At the onset of apoptosis it proteolytically
CC cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-|-Gly-217'
CC bond. Cleaves and activates sterol regulatory element binding proteins
CC (SREBPs) between the basic helix-loop-helix leucine zipper domain and
CC the membrane attachment domain. Cleaves and activates caspase-6, -7 and
CC -9. Triggers cell adhesion in sympathetic neurons through RET cleavage
CC (By similarity). Cleaves IL-1 beta between an Asp and an Ala, releasing
CC the mature cytokine which is involved in a variety of inflammatory
CC processes (By similarity). Cleaves and inhibits serine/threonine-
CC protein kinase AKT1 in response to oxidative stress. Acts as an
CC inhibitor of type I interferon production during virus-induced
CC apoptosis by mediating cleavage of antiviral proteins CGAS, IRF3 and
CC MAVS, thereby preventing cytokine overproduction. Cleaves XRCC4 and
CC phospholipid scramblase proteins XKR4, XKR8 and XKR9, leading to
CC promote phosphatidylserine exposure on apoptotic cell surface (By
CC similarity). {ECO:0000250|UniProtKB:P42574,
CC ECO:0000250|UniProtKB:P70677}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Strict requirement for an Asp residue at positions P1 and P4.
CC It has a preferred cleavage sequence of Asp-Xaa-Xaa-Asp-|- with a
CC hydrophobic amino-acid residue at P2 and a hydrophilic amino-acid
CC residue at P3, although Val or Ala are also accepted at this
CC position.; EC=3.4.22.56; Evidence={ECO:0000250|UniProtKB:P42574};
CC -!- SUBUNIT: Heterotetramer that consists of two anti-parallel arranged
CC heterodimers, each one formed by a 17 kDa (p17) and a 12 kDa (p12)
CC subunit. Interacts with BIRC6/bruce. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm.
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 of
CC caspase-7 protease and the large subunit of caspase-3 also occur and
CC vice versa (By similarity). {ECO:0000250}.
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 caspase
CC activity. Fas therefore activates caspase-3 not only by inducing the
CC cleavage of the caspase zymogen to its active subunits, but also by
CC stimulating the denitrosylation of its active site thiol (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase C14A family. {ECO:0000305}.
