靶點詳情

  • 功能：
    Plays a central role in virus morphogenesis and assembly. Acts as a viroporin and self-assembles in host membranes forming pentameric protein-lipid pores that allow ion transport. Also plays a role in the induction of apoptosis. Activates the host NLRP3 inflammasome, leading to IL-1beta overproduction.
  • 基因功能參考文獻：
    1. A structural model of a SARS-CoV E construct in LMPG micelles shows unequivocal intermolecular nuclear Overhauser effects. The C-terminal domain is mostly alpha-helical, and extramembrane intermolecular NOEs suggest interactions that may affect the TM channel conformation. PMID: 29474890
    2. distinct oligomeric forms of IBV E, one essential for assembly and the other with a role in disruption of the secretory pathway. PMID: 26136577
    3. Data show that the E protein has only one transmembrane (TM) domain in micelles, whereas the predicted beta-coil-beta motif forms a short membrane-bound alpha-helix connected by a disordered loop to the TM domain. PMID: 24668816
    4. These results suggested that the lipids are functionally involved in E protein ion channel activity, forming a protein-lipid pore. PMID: 22832120
    5. We showed that the SARS-CoV E protein is targeted to the Golgi region in HeLa cells and colocalizes most closely with GM130, which is a cis-Golgi protein. PMID: 21450821
    6. Data suggest that hijacking of PALS1 by SARS-CoV E plays a determinant role in the disruption of the lung epithelium in SARS patients. PMID: 20861307
    7. results show that the envelope (E) protein of severe acute respiratory syndrome-associated coronavirus can induce membrane permeability changes when expressed in Escherichia coli PMID: 15522242
    8. The E protein is not glycosylated. PMID: 15831954
    9. A novel molecular mechanism of T-cell apoptosis that contributes to the SARS-CoV-induced lymphopenia observed in most SARS patients is reported. PMID: 16048439
    10. expression of the SARS-CoV E protein in mammalian cells alters the membrane permeability of these cells; Systematic mutagenesis studies confirm that the membrane permeabilizing activity of the E protein is associated with its transmembrane domain PMID: 16507314
    11. The N- and C-termini of the SARS-CoV E protein are exposed to the cytoplasmic side of the membranes (N(cyto)C(cyto)). PMID: 16684538
    12. the expression of the structural protein, envelope (E), was down-regulated by 8b but not 8a or 8ab. PMID: 16876844
    13. analysis of the viroporin activity of SARS-CoV E protein PMID: 17037530
    14. conformational flexibility required during ion channel function PMID: 18658207
    15. both E and N proteins must be coexpressed with M protein for the efficient production and release of virus-like particles by transfected Vero E6 cells. PMID: 18753196
    16. Both the transmembrane domains of E protein are required to interact with M protein, while either of the hydrophilic regions (a.a. 1-10 or 60-76) is dispensable as shown by co-immunoprecipitation assay. PMID: 19322648
