What structural hallmark characterizes executioner caspases (such as Caspase-3 and Caspase-7) compared to initiator caspases (such as Caspase-8 and Caspase-9)?

Executioner caspases possess short pro-domains and require cleavage by initiator caspases for activation Executioner caspases contain long N-terminal CARD or DED domains that facilitate auto-dimerization Executioner caspases operate independently of proteolytic cleavage by binding directly to Cytochrome c Executioner caspases function as constitutive active monomers inside healthy cells

Correct Answer:

Executioner caspases possess short pro-domains and require cleavage by initiator caspases for activation
