– Abundant protease in the cytosolic granules of cytotoxic T-cells and NK-cells which activates caspase-independent pyroptosis when delivered into the target cell through the immunological synapse. It cleaves after Lys or Arg. Cleaves APEX1 after ‘Lys-31’ and destroys its oxidative repair activity. Cleaves the nucleosome assembly protein SET after ‘Lys-189’, which disrupts its nucleosome assembly activity and allows the SET complex to translocate into the nucleus to nick and degrade the DNA. Granzyme A/GZMA Protein, Mouse, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 31.6 kDa and the accession number is P11032.
