Function
This enzyme is necessary for target cell lysis in cell-mediated immune responses. It cleaves after Lys or Arg. Cleaves APEX1 after 'Lys-31' and destroys its oxidative repair activity. Involved in apoptosis. -
Sequence similarities
Belongs to the peptidase S1 family. Granzyme subfamily.
Contains 1 peptidase S1 domain. -
Cellular localization
Secreted. Cytoplasmic granule. - Information by UniProt
