Function
Granzyme K (GzmK) is a serine protease that sits in the dense-core granules of cytotoxic T lymphocytes and NK cells. While its gene neighbors encode granzymes A–C, GzmK stands out by lacking the N-linked glycosylation motifs that decorate most family members; this minimalist design keeps it stable at the low pH of the granule and allows it to emerge in an immediately active form once perforin has punched entry holes in a target cell. Inside the cytosol, GzmK bypasses the canonical caspase cascade: it clips Bid to tBid, nicks the anti-apoptotic SET complex, and generates single-stranded DNA nicks that push the cell into a swift form of death intermediate between apoptosis and necrosis. In addition, any GzmK that leaks into the extracellular space can process pro-IL-1β and activate PAR-2 on macrophages and endothelial cells, turning a private hit into a broader inflammatory alert.

This data was developed using HA723826, the same antibody clone in a different buffer formulation.
Western blot analysis of Granzyme K on different lysates with Rabbit anti-Granzyme K antibody (HA723826) at 1/5,000 dilution.
Lane 1: NK-92 cell lysate (20 µg/Lane)
Lane 2: HeLa cell lysate (negative) (20 µg/Lane)
Predicted band size: 29 kDa
Observed band size: 27 kDa
Exposure time: 10 seconds; ECL: K1801;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA723826) at 1/5,000 dilution was used in primary antibody dilution (K1803) at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.

Immunohistochemical analysis of paraffin-embedded human NK/T lymphoma tissue with Rabbit anti-Granzyme K antibody (HA723826) at 1/1,000 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HA723826) at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
