Perforin also referred to as PRF1 is a pore-forming protein that plays an important role in immune response. It appears as a 67-kDa protein and is mainly expressed in cytotoxic T cells and natural killer (NK) cells. The function of perforin involves the formation of transmembrane pores in the membranes of target cells aiding in the delivery of pro-apoptotic molecules. This mechanism is essential for the destruction of virus-infected cells and tumor cells. Techniques like perforin IHC and perforin ELISA are suitable for detecting and quantifying this protein in various samples.

Biological function summary

Perforin helps the immune system respond effectively against infected or malignant cells. It works in conjunction with granzymes forming a complex that perforates target cell membranes allowing granzymes to enter and induce apoptosis. Perforin's role in immune surveillance prevents the propagation of harmful cells within the body. Deficiency or malfunction in perforin can lead to compromised immune function or immune cell dysregulation.

Pathways

Perforin integrates into the cytotoxic T lymphocyte (CTL) and NK cell-mediated cytotoxicity pathways. These pathways include critical interactions with proteins like granzymes and Fas ligand (FasL) which orchestrate the apoptosis of abnormal cells. Through these pathways perforin ensures the body's ability to identify and eliminate threats. The granule exocytosis pathway in particular heavily depends on perforin's activity to execute effective immune responses.

Mutations or defects in perforin are linked to familial hemophagocytic lymphohistiocytosis (FHL) and some types of cancer. These conditions arise when perforin's ability to function correctly is impaired. For instance in FHL defective perforin hampers the immune cells' ability to kill target cells leading to uncontrolled immune activation. Furthermore in the context of cancer the proper functioning of perforin alongside proteins like granzyme B is critical for the surveillance and elimination of tumor cells.

靶点信息

Pore-forming protein that plays a key role in granzyme-mediated programmed cell death, and in defense against virus-infected or neoplastic cells (PubMed : 20889983, PubMed : 21037563, PubMed : 24558045, PubMed : 9058810, PubMed : 9164947). 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 (PubMed : 9058810). Can insert into the membrane of target cells in its calcium-bound form, oligomerize and form large pores (PubMed : 20889983, PubMed : 21037563). Promotes cytolysis and apoptosis of target cells by mediating the passage and uptake of cytotoxic granzymes (PubMed : 20038786, PubMed : 20225066, PubMed : 24558045, PubMed : 32299851). Facilitates the delivery of cationic cargo protein, while anionic or neural proteins are not delivered efficiently (PubMed : 24558045). Perforin pores allow the release of mature caspase-7 (CASP7) into the extracellular milieu (By similarity).
