GZMB (human)

GZMB 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. By staphylococcal enterotoxin A (SEA) in peripheral blood leukocytes. Inactivated by the serine protease inhibitor diisopropylfluorophosphate. Belongs to the peptidase S1 family. Granzyme subfamily. Note: This description may include information from UniProtKB.
