Rabbit anti-Human GSDMD Polyclonal Antibody | anti-GSDMD antibody
GSDMD Antibody
Phosphate buffered saline, pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
IHC: 1:50-1:200
Western Blot (WB)
(Western blot analysis of extracts of Jurkat cells, using GSDMD antibody.)
Immunohistochemistry (IHC)
(MBS9603503 at 1/100 staining Human lymph node tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary.)
Subunit Structure: In response to a canonical inflammasome stimulus, such as nigericin, recruited to NLRP3 inflammasone with similar kinetics to that of uncleaved CASP1 precursor. Although this recruitment is also observed in the absence of PYCARD, it is more efficient in its presence (By similarity). Gasdermin-D, N-terminal forms disulfide-linked homooligomers (16-mers) in a Ca(+2)-independent manner. Oligomerization occurs in the presence of membranes; cytosolic Gasdermin-D, N-terminal remains monomeric (PubMed:27281216).
Post-translational Modifications: Cleavage at Asp-275 by CASP1 (mature and uncleaved precursor forms) or CASP4 relieves autoinhibition and is sufficient to initiate pyroptosis (PubMed:26375003). Cleavage at Asp-87 by CASP3 (PubMed:28045099).
Similarity: Intramolecular interactions between N-and C-terminal domains may be important for autoinhibition in the absence of cleavage by inflammatory caspases CASP1 or CASP4. The intrinsic pyroptosis-inducing activity is carried by gasdermin-D, N-terminal, that is released upon cleavage by inflammatory caspases. Belongs to the gasdermin family.
NCBI and Uniprot Product Information
Predicted: 53 kDa
NCBI Description
Gasdermin D is a member of the gasdermin family. Members of this family appear to play a role in regulation of epithelial proliferation. Gasdermin D has been suggested to act as a tumor suppressor. Alternatively spliced transcript variants have been described. [provided by RefSeq, Oct 2009]
Uniprot Description
Gasdermin-D, N-terminal: Promotes pyroptosis in response to microbial infection and danger signals. Produced by the cleavage of gasdermin-D by inflammatory caspases CASP1 or CASP4 in response to canonical, as well as non-canonical (such as cytosolic LPS) inflammasome activators (PubMed:26375003, PubMed:26375259, PubMed:27418190). After cleavage, moves to the plasma membrane where it strongly binds to inner leaflet lipids, including monophosphorylated phosphatidylinositols, such as phosphatidylinositol 4-phosphate, bisphosphorylated phosphatidylinositols, such as phosphatidylinositol (4,5)-bisphosphate, as well as phosphatidylinositol (3,4,5)-bisphosphate, and more weakly to phosphatidic acid and phosphatidylserine (PubMed:27281216). Homooligomerizes within the membrane and forms pores of 10 - 15 nanometers (nm) of inner diameter, possibly allowing the release of mature IL1B and triggering pyroptosis (PubMed:27418190, PubMed:27281216). Exhibits bactericidal activity. Gasdermin-D, N-terminal released from pyroptotic cells into the extracellular milieu rapidly binds to and kills both Gram-negative and Gram-positive bacteria, without harming neighboring mammalian cells, as it does not disrupt the plasma membrane from the outside due to lipid-binding specificity (PubMed:27281216). Under cell culture conditions, also active against intracellular bacteria, such as Listeria monocytogenes (). Strongly binds to bacterial and mitochondrial lipids, including cardiolipin. Does not bind to unphosphorylated phosphatidylinositol, phosphatidylethanolamine nor phosphatidylcholine (PubMed:27281216).
