Funkcija

uredi

Kaspaza-7 je član porodice proteina kaspaza (cistein [[asparaginska kiselinas|aspartat proteaza) i pokazalo se da je stražarski protein apoptoza. Sekvencijalna aktivacija kaspaza igra centralnu ulogu u fazi izvršenja ćelije apoptoza. Kaspaze postoje kao neaktivni proenzimi koji se podvrgavaju proteolitskoj obradi uzvodnim kaspazama (kapaza-8,9) na konzerviranim asparaginskim ostacima, kako bi se dobile dvije podjedinice, velika i mala, koje se dimeriziraju i formiraju aktivni enzim u obliku heterotetramer. Prekursor ove kaspaze cepaju kapazu-3, kapazu-10 i kapazu-9. Aktivira se na podražaje ćelijske smrti i inducira apoptozu. Alternativna prerada RNK rezultira u četiri varijante transkripta, kodirajući tri različite izoforme.[6]
