It cleaves after Asp. Once delivered into the target cell, acts by catalyzing cleavage of gasdermin-E (GSDME), releasing the pore-forming moiety of GSDME, thereby triggering pyroptosis and target cell death. Seems to be linked to an activation cascade of caspases (aspartate-specific cysteine proteases) responsible for apoptosis execution. Cleaves caspase-3, -9 and -10 (CASP3, CASP9 and CASP10, respectively) to give rise to active enzymes mediating apoptosis. Cleaves and activates CASP7 in response to bacterial infection, promoting plasma membrane repair\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDomain- and isoform-aware assay design to improve biological interpretation across model systems.\u003c\/li\u003e\n\u003cli\u003eQuantitative workflows emphasizing calibration standards, spike-in controls, and cross-lot comparability.\u003c\/li\u003e\n\u003cli\u003eIn vitro binding\/kinetics profiling (SPR\/BLI) to connect biochemical interactions with cellular phenotypes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrepare aliquots of GZMB for reproducible in vitro assays (minimize freeze–thaw).\u003c\/li\u003e\n\u003cli\u003eUse GZMB as a calibration standard in quantitative assays (standard curve setup).\u003c\/li\u003e\n\u003cli\u003eMeasure binding interactions to GZMB by SPR\/BLI (kinetic profiling in vitro).\u003c\/li\u003e\n\u003cli\u003eGenerate antibodies to GZMB and benchmark specificity in ELISA\/WB (control samples).\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret results in the context of the biological system, assay format, and any known domain\/isoform constraints for the target.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider species- and isoform-specific differences when comparing results across models or homologs.\u003c\/li\u003e\n\u003cli\u003eFor quantitative assays, include appropriate negative controls and matrix-matched spike-in concepts to assess non-specific signal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProtKB entry (P10144) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/P10144 - NCBI Gene search (GZMB) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=GZMB - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=GZMB - Reactome pathway browser — Reactome: https:\/\/reactome.org\/ - InterPro protein family resource — EMBL-EBI: https:\/\/www.ebi.ac.uk\/interpro\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53059295740269,"sku":"CSB-EP010082HUc7-1MG","price":1812.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059435463021,"sku":"CSB-EP010082HUc7-100UG","price":419.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059435495789,"sku":"CSB-EP010082HUc7-20UG","price":224.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP010082HUc7-SDS.jpg?v=1772280327","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-granzyme-b-gzmb-bhp10515757","provider":"BioHippo","version":"1.0","type":"link"}
