RelevanceFunction: May promote pyroptosis (Probable). Upon cleavage in vitro of genetically engineered GSDMA, the released N-terminal moiety binds to some types of lipids, such as possibly phosphatidylinositol (4,5)-bisphosphate. Homooligomerizes within the membrane and forms pores of 10 -15 nanometers (nm) of inner diameter, triggering cell death. Also binds to bacterial and mitochondrial lipids, including cardiolipin, and exhibits bactericidal activity (PubMed:27281216). The physiological relevance of these observations is unknown. Tissue specificity: Expressed predominantly in the gastrointestinal tract and, at a lower level, in the skin. Also detected in mammary gland. In the gastrointestinal tract, mainly expressed in differentiated cells, including the differentiated cell layer of esophagus and mucus-secreting pit cells of the gastric epithelium. Down-regulateded in gastric cancer cells. Similarity: Belongs to the gasdermin family. Domain: Intramolecular interactions between N- and C-terminal domains may be important for autoinhibition in the absence of activation signal. The intrinsic pyroptosis-inducing activity is carried by the N-terminal domain.

GSDMA was immunoprecipitated from 0.35 mg of HeLa (human epithelial cell line from cervix adenocarcinoma) cells stably transfected with human GSDMA expression vector, containing a DDDDK-tag, whole cell lysate with ab232254 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab232254 at 1/1,000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10,000 dilution.

Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 1 second.
The bands lower than 50 kDa are the degraded exogenous GSDMA protein.
The cells were kindly provided by our collaborator Dr. Feng Shao, NIBS.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab232254).
