Function

Gasdermin-DPrecursor of a pore-forming protein that plays a key role in host defense against pathogen infection and danger signals (PubMed:26375003, PubMed:26375259, PubMed:26611636, PubMed:27383986, PubMed:27385778, PubMed:27418190). This form constitutes the precursor of the pore-forming protein: upon cleavage, the released N-terminal moiety (Gasdermin-D, N-terminal) binds to membranes and forms pores, triggering pyroptosis (PubMed:26375003, PubMed:26375259, PubMed:26611636, PubMed:27383986, PubMed:27385778, PubMed:27418190).Gasdermin-D, N-terminalPromotes pyroptosis in response to microbial infection and danger signals (PubMed:26375003, PubMed:26375259, PubMed:26611636, PubMed:27383986, PubMed:27385778, PubMed:27418190, PubMed:32820063). Produced by the cleavage of gasdermin-D by inflammatory caspases CASP1 or CASP4/CASP11 in response to canonical, as well as non-canonical (such as cytosolic LPS) inflammasome activators (PubMed:26375003, PubMed:26375259, PubMed:26611636, PubMed:27383986, PubMed:27385778, 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:27383986, PubMed:27339137). Homooligomerizes within the membrane and forms pores of 10-15 nanometers (nm) of inner diameter, allowing the release of mature IL1B and triggering pyroptosis (PubMed:27383986). Exhibits bactericidal activity (PubMed:27383986). 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:27383986). Under cell culture conditions, also active against intracellular bacteria, such as Listeria monocytogenes (PubMed:27383986). Also active in response to MAP3K7/TAK1 inactivation by Yersinia toxin YopJ, which triggers cleavage by CASP8 and subsequent activation (PubMed:30361383, PubMed:30381458). Strongly binds to bacterial and mitochondrial lipids, including cardiolipin. Does not bind to unphosphorylated phosphatidylinositol, phosphatidylethanolamine nor phosphatidylcholine (PubMed:27383986).

Activity summary

GSDMD also known as gasdermin D is a protein known for its role in pyroptosis a form of programmed cell death. Its molecular weight is approximately 53 kDa. Mechanically GSDMD operates by forming pores in cell membranes. These pores disrupt cellular homeostasis and eventually lead to cell lysis. GSDMD is mainly expressed in immune cells including macrophages and neutrophils. Researchers frequently use GSDMD Western blot and GSDMD ELISA for its detection and quantification in various studies.

Biological function summary

Gasdermin D functions in the execution of immune responses against infections. It acts as an effector molecule that participates directly in pyroptosis by disrupting mitochondrial membranes. GSDMD operates as part of a larger inflammasome complex initiated by inflammatory signals. The inflammasome activates inflammatory caspases that cleave GSDMD enabling its active form to execute pyroptosis. This process releases cytokines like IL-1β enhancing the inflammatory response.

Pathways

GSDMD is important in the pyroptosis pathway initiated by the inflammasome. This process involves Caspase-1 a protease responsible for cleaving pro-inflammatory cytokines and initiating pyroptosis. Another significant pathway includes NLRP3 inflammasome which acts upstream to activate Caspase-1 and subsequently GSDMD establishing the overall inflammatory response in the innate immune system. Through these pathways GSDMD interacts closely with proteins like IL-18 an essential inflammatory mediator.

Associated diseases and disorders

Gasdermin D has links to inflammatory diseases such as rheumatoid arthritis and sepsis. In rheumatoid arthritis the excessive activation of GSDMD leads to chronic joint inflammation mediated by activated immune cells. In sepsis over-activation of the pyroptosis pathway may cause severe systemic inflammation driven by GSDMD activity exacerbating cytokine release. Connections exist between GSDMD and other proteins such as Caspase-11 which can also initiate GSDMD cleavage independently and has roles in non-canonical inflammasome pathways influencing these conditions.
