WebFeb 12, 2001 · Granzyme B is the most powerful pro-apoptotic member of the granzyme family. Like caspases, cysteine proteases that play an important role in apoptosis, it can cleave proteins after acidic residues, especially aspartic acid. Other granzymes may serve additional functions, and some may not induce apoptosis. WebMay 1, 2001 · GzmA and GzmB cleave laminB in isolated nuclei independently of caspase activation. (a and b) Four-fold dilutions of GzmA ranging from 0.4 to 200 nM were added to isolated HeLa nuclei for the indicated times. Full-length laminB is indicated by a black arrowhead, the C-terminal 25-kDa laminB fragment by a white arrowhead, and the N …
