靶點詳情

  • 功能:
    Pore-forming protein that plays a key role in secretory granule-dependent cell death, and in defense against virus-infected or neoplastic cells. Plays an important role in killing other cells that are recognized as non-self by the immune system, e.g. in transplant rejection or some forms of autoimmune disease. Can insert into the membrane of target cells in its calcium-bound form, oligomerize and form large pores. Promotes cytolysis and apoptosis of target cells by facilitating the uptake of cytotoxic granzymes.
  • 基因功能參考文獻:
    1. Perforin binds to membranes and undergoes substantial structural re-arrangement to form pores that enable diffusion of granzyme into the target cell [Review]. PMID: 28757431
    2. findings show that N-linked glycosylation of the perforin C-terminus at Asn549 within the endoplasmic reticulum inhibits oligomerisation of perforin monomers and protects the host cell from premature pore formation; studies reveal a post-translational regulatory mechanism essential for maintaining perforin in an inactive state until its secretion from the inhibitory acidic environment of the secretory granule PMID: 28808112
    3. Study focuses on the role of perforin in both protecting and promoting human disease.

[review] PMID: 28757574
    4. Our studies suggest that although moderate levels of expression can result in partial amelioration of the hemophagocytic lymphohistiocytosis (HLH)phenotype, high levels of perforin expression per cell are required for complete correction of HLH. PMID: 27471778
