'''Gasdermin''' (GSDM)  is the substrate of the inflamamatory [[Caspase]] downstream from inflamasomes which activate caspase.  Inflammasomes are supramolecular signaling  assemblies activating the lytic process against exogenous pathogens. GSDM is required for cytokine release and pyroptosis <ref>PMID:31451512</ref>.  Pyropptosis is the regulated lytic cell death mediated by GSMD pore formation.  GSDM D contains 2 domains: the N-terminal fragment which is pore-forming and the repressive C-terminal.  The GSDM family contains 6 members in human.
