Granzyme B is a 27 kDa serine protease stored in granules of activated cytotoxic T cells and NK cells. Upon target cell contact,granzyme B is directionally exocytosed and assisted by perforin,enters the target cell. With its unique substrate specificity (granzyme B cleaves after Asp),granzyme B processes and activates various pro-caspases thereby inducing apoptosis in the target cell.
