This enzyme is necessary for target cell lysis in cell-mediated immune responses. It cleaves after Asp. Seems to be linked to an activation cascade of caspases (aspartate-specific cysteine proteases) responsible for apoptosis execution. Cleaves caspase-3, -7, -9 and 10 to give rise to active enzymes mediating apoptosis.
Belongs to the peptidase S1 family. Granzyme subfamily. Contains 1 peptidase S1 domain.
Cytoplasmic granule. Cytoplasmic granules of cytolytic T-lymphocytes and natural killer cells.
