Granzyme B/GZMB Protein, Human (HEK293, His)
Based on 1 Customer Validation
Granzyme B (GZMB) is a cytosolic protease enriched in cytotoxic T cells and natural killer cells and is critical for immune defense. Upon delivery to target cells, GZMB activates caspase-independent pyroptosis by cleaving gasdermin-E (GSDME). Granzyme B/GZMB Protein, Human (HEK293, His) is the recombinant human-derived Granzyme B/GZMB protein, expressed by HEK293, with C-6*His labeled tag.

Description
Granzyme B (GZMB) is a cytosolic protease enriched in cytotoxic T cells and natural killer cells and is critical for immune defense. Upon delivery to target cells, GZMB activates caspase-independent pyroptosis by cleaving gasdermin-E (GSDME). Granzyme B/GZMB Protein, Human (HEK293, His) is the recombinant human-derived Granzyme B/GZMB protein, expressed by HEK293, with C-6*His labeled tag.
Background
Granzyme B (GZMB) is a highly abundant protease residing in the cytosolic granules of cytotoxic T-cells and natural killer cells, playing a pivotal role in immune defense mechanisms. Upon delivery into the target cell through the immunological synapse, GZMB activates caspase-independent pyroptosis by catalyzing the cleavage of gasdermin-E (GSDME). This results in the release of the pore-forming moiety of GSDME, triggering pyroptosis and ultimately leading to target cell death. GZMB exhibits a substrate specificity for cleavage after aspartate residues. Additionally, it is implicated in an activation cascade of caspases, including caspase-3, -9, and -10, thereby contributing to apoptosis execution. Moreover, GZMB is involved in the response to bacterial infection, where it cleaves and activates caspase-7, promoting plasma membrane repair. The multifaceted activities of GZMB highlight its crucial role in orchestrating immune responses and cellular defense mechanisms.
Verified Bioactivity
