Overview	Apoptosisisanevolutionarilyconservedformofcellsuicide,whichfollowsaspecializedcellularprocess.Thecentralcomponentofthisprocessisacascadeofproteolyticenzymescalledcaspases.Theseenzymesparticipateinaseriesofreactionsthataretriggeredinresponsetopro-apoptoticsignalsandresultinthecleavageofproteinsubstrates,causingthedisassemblyofthecell(Arends&Wyllie1991). CaspaseshavebeenidentifiedinorganismsrangingfromC.eleganstohumans.Themammaliancaspasesplaydistinctrolesinapoptosisandinflammation.Inapoptosis,caspasesareresponsIBLeforproteolyticcleavagesthatleadtocelldisassembly(effectorcaspases),andareinvolvedinupstreamregulatoryevents(initiatorcaspases).Anactivecaspaseconsistsoftwolargeandtwosmallsubunitsthatformtwoheterodimerswhichassociateinatetramer(Sleeetal.1999;Salvesen&Dixit1997;Alnemrietal.1996).Incommonwithotherproteases,caspasesaresynthesizedasprecursorsthatundergoproteolyticmaturation,eitherautocatalyticallyorinacascadebyenzymeswithsimilarspecificity(Sleathetal.1990).
