Descripción

General description

Granzyme B (GzmB) is a serine protease which is stored in granules of activated cytotoxic T cells and NK cells. GZMB codes for granzyme B.

Biochem/physiol Actions

Granzyme B is considered as the marker of activated CTLs (cytotoxic T-cells), which mediates target-cell apoptosis. It induces apoptosis in caspase-dependent and caspase-independent manner. After contact with target cells, granzyme B is directionally exocytosed, and then enters the target cell with assistance from perforin. Granzyme B specifically cleaves after Asp residues, and particularly processes and activates various pro-caspases. This induces apoptosis in the target cell.

Unit Definition

One unit is defined as the amount of enzyme that hydrolyzes 1 pmol/min of IETD-AFC per min at 37°C in 50 mM HEPES, pH 7.5 containing 10 mM CaCl₂.

Physical form

Lyophilized powder, containing HEPES buffer (original solution at pH 7.5)
