GSDME (Gasdermin E) is a member of the gasdermin family of pore-forming proteins that regulate programmed cell death and inflammatory signaling. Encoded by the GSDME gene, the full-length protein contains an N-terminal pore-forming domain and a C-terminal autoinhibitory domain. Under apoptotic conditions, activation of caspase-3 leads to proteolytic cleavage of GSDME, releasing the N-terminal fragment, which oligomerizes and inserts into the plasma membrane to form pores. This process can convert non-lytic apoptosis into a lytic, inflammatory form of cell death resembling pyroptosis, resulting in membrane rupture and release of intracellular contents. GSDME has been implicated in cancer biology, chemotherapy response, and tissue injury, and was originally identified in association with autosomal dominant hearing loss (historically referred to as DFNA5). Detection of cleaved GSDME is commonly used as a marker of caspase-3-mediated pore formation and inflammatory cell death.
