Summary
Protein Function
Caspase-2 proteolytically cleaves other proteins. It belongs to a family of cysteine proteases called caspases that cleave proteins only at an amino acid following an aspartic acid residue. Within this family, caspase-2 is part of the Ich-1 subfamily. It is one of the most conserved caspases in different species of animal. Caspase-2 has a similar amino acid sequence to initiator caspases, including caspase 1, caspase-4, caspase-5, and caspase-9. It is produced as a zymogen, which contains a long pro-domain that is similar to that of caspase-9 and contains a protein interaction domain known as a CARD domain. Pro-caspase-2 contains two subunits, p19 and p12. (From Wikipedia)
Caspase-2 was discovered as the first mammalian apoptotic caspase. Caspase-2 is engaged as an initiator in both the extrinsic and the intrinsic pathways of apoptosis. Additionally, Caspase-2 serves in neuronal cells both as the default initiator and the default executioner caspase. (PMID: 12920126)
Cys Function & Property
The catalytic triad in Caspase-3 comprises Cys320, His277 and the backbone carbonyl oxygen atom of Arg219, which points towards the Nϵ atom of His277.
