General description

GSDMD (gasdermin D) also known as DFNA5L or Gasdermin domain-containing 1 (GSDMDC1), belongs to the gasdermin protein family of epithelial proliferation regulators. GSDMD is expressed in the upper gastrointestinal epithelium differentiating cells and has been suggested to act as a tumor suppressor since it is suppressed in high percentage of esophageal squamous cell carcinomas and gastric cancers. In the presence of lipopolysaccharide (LPS) from Gramnegative bacteria, inflammatory caspases including caspase-4/11 activates downstream pyroptotic cell death, interleukin-1β processing, and lethal septic shock. The absence of GSDMD, completely blocked LPS electroporation-triggered pyroptosis in studies performed using GSDMD siRNA knockdown or GSDMD knockout (both human HeLa cells and iBMDM mouse cells). It was also reported that Caspase-4/11 specifically cleaves GSDMD after Asp275, leading to gasdermin-N domain that bears intrinsic pyroptosisinducing activity. 4 Furthermore, GSDMD-mediated pyroptosis plays an important role in mature IL-1β release without affecting its maturation.

Monoclonal Anti-GSDMD recognizes human GSDMD.
Monoclonal Anti-GSDMD (mouse IgG1 isotype) is derived from the GSD-14hybridoma, produced by the fusion of mouse myeloma cells and splenocytes from a mouse immunized with synthetic peptide corresponding to the internal region of human GSDMD, conjugated to keyhole limpet hemocyanine (KLH). Gasdermin D (GSDMD) is also known as DFNA5L or gasdermin domain-containing 1 (GSDMDC1). It belongs to the gasdermin protein family of epithelial proliferation regulators and is expressed in the upper gastrointestinal epithelium differentiating cells.

Immunogen

Synthetic peptide of human GSDMD, conjugated to KLH

Application

The antibody is recommended to use in various immunological techniques, including Immunoblot (∼53 kDa) and Immunofluorescence.

Inflammatory caspases (caspase-1, -4, -5 and -11) are critical for innate defences. Caspase-1 is activated by ligands of various canonical inflammasomes, and caspase-4, -5 and -11 directly recognize bacterial lipopolysaccharide, both of which trigger pyroptosis. Despite the crucial role in

Intracellular lipopolysaccharide from Gram-negative bacteria including Escherichia coli, Salmonella typhimurium, Shigella flexneri, and Burkholderia thailandensis activates mouse caspase-11, causing pyroptotic cell death, interleukin-1β processing, and lethal septic shock. How caspase-11 executes these downstream signalling events is largely unknown. Here we
