FunFam 14: Caspase 10, apoptosis-related cysteine peptidase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Caspase-10. [EC: 3.4.22.63]
Strict requirement for Asp at position P1 and has a preferred cleavage sequence of Leu-Gln-Thr-Asp-|-Gly.
  • Caspase-10 is an initiator caspase, as are caspase-2 (EC 3.4.22.55), caspase-8 (EC 3.4.22.61) and caspase-9 (EC 3.4.22.62).
  • Like caspase-8, it contains two tandem death effector domains (DEDs) in its N-terminal prodomain, which play a role in procaspase activation.
  • Has many overlapping substrates in common with caspase-8, such as RIP (the cleavage of which impairs NF-kappa-B survival signaling 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).
  • Bid, a Bcl2 protein, can be cleaved by caspase-3 (EC 3.4.22.56), 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.
  • Belongs to peptidase family C14.
