Systematic name:



Caspase-10 is an initiator caspase, as are caspase-2 (EC, caspase-8 (EC and caspase-9 (EC [1]. Like caspase-8, caspase-10 contains two tandem death effector domains (DEDs) in its N-terminal prodomain, which play a role in procaspase activation [1]. The enzyme has many overlapping substrates in common with caspase-8, such as RIP (the cleavage of which impairs NF-κB survival signalling and starts the cell-death process) and PAK2 (associated with some of the morphological features of apoptosis, such as cell rounding and apoptotic body formation) [2]. Bid, a Bcl2 protein, can be cleaved by caspase-3 (EC, caspase-8 and caspase-10 at Lys-Gln-Thr-Asp┼ to yield the pro-apoptotic p15 fragment. The p15 fragment is N-myristoylated and enhances cytochrome c release from mitochondria (which initiatiates the intrinsic apoptosis pathway). Bid can be further cleaved by caspase-10 and granzyme B but not by caspase-3 and caspase-8 at Ile-Glu-Thr-Asp┼ to yield a p13 fragment that is not N-myristoylated [2]. Belongs in peptidase family C14.
