Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp270 of human Gasdermin E protein.
Background
The gasdermin family, which includes GSDMA, GSDMB, GSDMC, GSDMD, and GSDME, has been shown to play a role in inflammation and cell death. Gasdermin D has been reported to have a critical role as a downstream effector of pyroptosis (1,2). Pyroptosis is a lytic type of cell death triggered by inflammasomes, multiprotein complexes assembled in response to pathogen-associated molecular patterns (PAMPs) or danger-associated molecular patterns (DAMPs) that result in the activation of caspase-1 and subsequent cleavage of pro-inflammatory cytokines IL-1β and IL-18 (3). Gasdermin D was identified by two independent groups as a substrate of inflammatory caspases, caspase-1 and caspase-11/4/5, producing two fragments: GSDMD-N and GSDMD-C. Cleavage results in release of an intramolecular inhibitory interaction between the N- and C-terminal domains, allowing the N-terminal fragment GSDMD-N to initiate pyroptosis through the formation of pores on the plasma membrane (4-7).
Gasdermin E (GSDME), also known as DFNA5, was originally identified as a genetic cause of nonsyndromic hearing loss (8). Like other gasdermin family members, Gasdermin E contains an amino-terminal pore forming domain that triggers pyroptosis. Cleavage of Gasdermin E at Asp270 is induced by apoptotic-associated Caspase-3, converting apoptotic signals to pyroptosis (9). In addition, cleavage of Gasdermin E can be induced by Granzyme B secreted by NK cells and contributes to tumor suppressive activity (10). Gasdermin E expression is suppressed in several types of cancer including gastric, colorectal, and breast carcinoma, and may be associated with decreased survival (11-13). In contrast, an increase in Gasdermin E, including the amino-terminal pore-forming fragment, is associated with conditions of excessive inflammation (14-16).
