Webb1 dec. 2002 · Initiator caspases may directly process and activate executioner caspases 3, 6, and 7 (for review, see Hengartner, 2000). Caspases can selectively be inhibited by small peptides, mimicking the substrate recognition site, carrying electrophiles such as aldehydes, nitriles, or ketones at their C terminus that react with the active site Cys. Webb10 apr. 2024 · Caspases are divided into two classes use caspases that play a role in apoptosis and inflammation.

WebbCaspase 7 is an executioner caspase that was identified based on its homology with caspases 1 and 3, as well as the C. elegans cell death protein CED-3. Alternative splicing of Caspase-7 mRNA results in the production of 3 distinct isoforms. Caspase-7 activity can be directly inhibited by XIAP expression. WebbCaspases are central components of the machinery through cleavage at specific internal Asp residues that responsible for apoptosis. Recent structural and bio-separate the large and small subunits (Figure 1). The chemical studies on procaspases, IAPs, Smac/DIA-initiator caspases, however, are autoactivated

Once activated, initiator caspases such as Caspase 9 will cleave and activate other executioner caspases. This leads to degradation of cellular components for apoptosis. Extrinsic apoptopic pathway: The caspase cascade is also activated by extracellular ligands, via cell surface Death Receptors.
