Five granzymes are expressed in human NK cells (Grz A, B, H, K and M)
GrzA and GrzK are trypsins (cleaving at basic residues arginine and lysine)
GrzB is an aspase, cleaving after aspartic acid residues, and GrzH is a chymase, cleaving after hydrophobic residues such as phenylalanine.
GrzM has a unique enzyme specificity, preferring cleavage after methionine, leucine, or isoleucine.

VAV1 induces granule exocytosis of granzyme A probably via RAC1-ERK pathway. The absence of Vav1 results in defective granule exocytosis and reduced ability to lyse tumor targets.
