Description
Granzyme B, also known as Gzmb, is a member of the granzyme family of cell death-inducing serine proteases specially expressed in the granules of cytotoxic T lymphocytes (CTLs) and NK cells. It plays crucial role for target cell lysis in cell-mediated immune responses. This protein is linked to an activation cascade of caspases (aspartate-specific cysteine proteases) responsible for apoptosis execution. It cleaves caspase-3, -7, -9 and 10 to give rise to active enzymes mediating apoptosis. Recombinant mouse Granzyme B, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques
