Descriptions

Biochem/physiol Actions

Granzyme B is considered as the marker of activated CTLs (cytotoxic T-cells), which mediates target-cell apoptosis. It induces apoptosis in caspase-dependent and caspase-independent manner. After contact with target cells, granzyme B is directionally exocytosed, and then enters the target cell with assistance from perforin. Granzyme B specifically cleaves after Asp residues, and particularly processes and activates various pro-caspases. This induces apoptosis in the target cell.

General description
