Perforin-1 is a pore forming cytolytic protein. It is found in the granules of cytotoxic T lymphocytes and natural killer cells that drive to osmotic lysis of the target cells and subsequently empower granzymes to enter the target cells and stimulate apoptosis. The lytic membrane-inserting part of perforin is the MACPF domain. Perforin-1 has structural and functional similarities to complement component 9. It has been evaluated that perforin-1 acts by creating holes in the plasma membrane which generate an influx of calcium and begins membrane repair mechanisms. These repair mechanisms bring perforin-1 and granzymes into early endosomes. The expression of perforin-1 is reportedly upregulated in activated CD8+ T-cells, natural killer cells and some CD4+ T-cells.
