Purity > 90% as determined by SDS-PAGE. MW: 27.5kDa. Full Length of Mature Protein: 21-247aa. N-terminal 6xHis-tagged. Homo sapiens (Human). This enzyme is necessary for target cell lysis in cell-mediated immune responses. It cleaves after Asp. Ses 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.
