PRF1
This gene encodes a protein with structural similarities to complement component C9 that is important in immunity.
Full Name
Perforin 1
Function
Pore-forming protein that plays a key role in secretory granule-dependent cell death, and in defense against virus-infected or neoplastic cells (PubMed:9058810, PubMed:9164947, PubMed:20889983, PubMed:21037563).
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 facilitating the uptake of cytotoxic granzymes (PubMed:20038786, PubMed:20225066, PubMed:32299851).

Cellular Location
Cytolytic granule
Secreted
Cell membrane
Endosome lumen
Stored in cytolytic granules of cytolytic T-lymphocytes and secreted into the cleft between T-lymphocyte and target cell (PubMed:20038786).
Inserts into the cell membrane of target cells and forms pores (PubMed:20889983).
Membrane insertion and pore formation requires a major conformation change (PubMed:20889983).
May be taken up via endocytosis involving clathrin-coated vesicles and accumulate in a first time in large early endosomes (PubMed:20038786).

Involvement in disease
Hemophagocytic lymphohistiocytosis, familial, 2 (FHL2):
A rare disorder characterized by immune dysregulation with hypercytokinemia, defective function of natural killer cell, and massive infiltration of several organs by activated lymphocytes and macrophages. The clinical features of the disease include fever, hepatosplenomegaly, cytopenia, and less frequently neurological abnormalities ranging from irritability and hypotonia to seizures, cranial nerve deficits and ataxia.
