Function

Gasdermin-E. Precursor of a pore-forming protein that converts non-inflammatory apoptosis to pyroptosis (PubMed:27281216, PubMed:28459430, PubMed:33852854, PubMed:35594856, PubMed:36607699). This form constitutes the precursor of the pore-forming protein: upon cleavage, the released N-terminal moiety (Gasdermin-E, N-terminal) binds to membranes and forms pores, triggering pyroptosis (PubMed:28459430). Gasdermin-E, N-terminal. Pore-forming protein produced by cleavage by CASP3 or granzyme B (GZMB), which converts non-inflammatory apoptosis to pyroptosis or promotes granzyme-mediated pyroptosis, respectively (PubMed:27281216, PubMed:28459430, PubMed:32188940, PubMed:33852854, PubMed:35594856). After cleavage, moves to the plasma membrane, homooligomerizes within the membrane and forms pores of 10-15 nanometers (nm) of inner diameter, allowing the release of mature interleukins (IL1B and IL16) and triggering pyroptosis (PubMed:28459430, PubMed:32188940, PubMed:33852854, PubMed:35594856). Binds to inner leaflet lipids, bisphosphorylated phosphatidylinositols, such as phosphatidylinositol (4,5)-bisphosphate (PubMed:28459430). Cleavage by CASP3 switches CASP3-mediated apoptosis induced by TNF or danger signals, such as chemotherapy drugs, to pyroptosis (PubMed:27281216, PubMed:28459430, PubMed:32188940). Mediates secondary necrosis downstream of the mitochondrial apoptotic pathway and CASP3 activation as well as in response to viral agents (PubMed:28045099). Exhibits bactericidal activity (PubMed:27281216). Cleavage by GZMB promotes tumor suppressor activity by triggering robust anti-tumor immunity (PubMed:21522185, PubMed:32188940). Suppresses tumors by mediating granzyme-mediated pyroptosis in target cells of natural killer (NK) cells: cleavage by granzyme B (GZMB), delivered to target cells from NK-cells, triggers pyroptosis of tumor cells and tumor suppression (PubMed:31953257, PubMed:32188940). May play a role in the p53/TP53-regulated cellular response to DNA damage (PubMed:16897187). Gasdermin-E, N-terminal. (Microbial infection) Pore-forming protein, which promotes maternal placental pyroptosis in response to Zika virus infection, contributing to adverse fetal outcomes.

Activity summary

DFNA5 also known as GSDME (Gasdermin E) is a protein encoded by the GSDME gene. It has a molecular mass of approximately 59 kDa. The protein is expressed in various tissues including the cochlea in the inner ear and some epithelial tissues. Mechanically DFNA5/GSDME plays a role in inducing cell membrane pore formation leading to cell lysis. This activity relates to its involvement in processes like cell death specifically pyroptosis where the cell undergoes a form of programmed necrosis.

Biological function summary

DFNA5/GSDME serves as a pore-forming protein that facilitates pyroptotic cell death usually upon cleavage by caspase-3. This activity is important for innate immune response and the maintenance of cellular homeostasis. DFNA5/GSDME operates independently and does not form part of large protein complexes. The cleaved form inserts into the lipid bilayer of cell membranes contributing to the execution of cell death particularly under stress conditions or cellular insult.

Pathways

DFNA5/GSDME is involved in the pyroptosis and apoptosis pathways. It plays an essential role in the cellular response to inflammation and stress signals by interacting with caspase-3 a critical protease in the apoptosis pathway. The balance between apoptosis and pyroptosis decides cell fate with DFNA5/GSDME activation tipping towards pyroptotic cell death. The interconnection with other gasdermin family proteins such as GSDMD is notable as they share functional and structural similarities in promoting necrosis-like cell death processes.

Associated diseases and disorders

Mutations in the DFNA5 gene relate to progressive hearing loss (nonsyndromic sensorineural deafness). Dysregulation of GSDME has also been implicated in cancer where altered expression promotes tumorigenesis or tumor suppression depending on the context. In hearing loss GSDME's interaction with pathways influencing apoptosis highlights its pathogenic role while in cancer connections to caspase-3 show a potential dichotomy in cell survival and cell death regulation.

    Overlay histogram showing SHSY5Y cells stained with ab225520 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab225520, 1/5000 dilution) for 30 min at 22°C.

    Isotype control antibody (black line) was Rabbit IgG (monoclonal) Phycoerythrin (PE Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab209478) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

    Acquisition of >5,000 events were collected using a 50 mW Yellow/Green laser (561nm) and 586/15 bandpass filter.
