WebbAside from its central role in the initiation of cell death, ... According to the action mechanism, apoptotic caspases are classified into initiator caspases and executioner caspases. Caspase-3 and caspase-9 belong to the apoptotic caspase group; caspase-3 is an executioner and caspase-9 is an initiator. 17. Webb5 apr. 2024 · There are two types of apoptotic caspases: initiator (apical) caspases and effector (executioner) caspases. Caspases also have a role in inflammation, whereby it directly processes pro-inflammatory cytokines such as pro-IL1β. Caspases also play a role in cell proliferation, tumor inhibition, cell differentiation, neurodevelopment and aging.

Webbv-FLIPs are viral proteins that were first identified as modulators of apoptosis; they contain two death effector domains, which are also found in some initiator caspases such as procaspase-8. These v-FLIP proteins can be recruited to the DISC through the binding of the death effector domain to similar domains in the adaptor proteins, but are otherwise … WebbThe proximity-driven dimerization model describes how initiator caspases respond to induced proximity and offers an explanation for their activation. Regardless of how …

WebbInitiator caspases (e.g., CASP2, CASP8, CASP9, and CASP10) cleave inactive pro-forms of effector caspases, thereby activating them. Effector caspases (e.g., CASP3, CASP6, CASP7) in turn cleave other protein substrates within the cell, to trigger the apoptotic process. The initiation of this cascade reaction is regulated by caspase inhibitors. WebbCaspases are cysteine proteases that are normally activated in apoptosis through proteolytic cleavage by other caspase molecules and formation of active dimers. Both initiator and executioner caspases can be inhibited by inhibitors of apoptosis (IAPs). While inactive initiator caspases are monomers, inactive executioner caspases are …
