Perforin, originally cloned from mouse cytotoxic T-lymphocyte (CTL), is a 555-amino acid protein with a 21-amino acid signal peptide and is a potent cytolytic pore-forming protein.
It is a specific marker of functionally active cytotoxic T-lymphocytes (CTLs) and natural killer (NK) cells.
Fas ligand and perforin are the two key effector mechanisms in T cell-mediated cytotoxicity.
These molecules mediate cytolysis of target cells by membrane damage and apoptosis, an important mechanism in the immune defense against tumors and virus infection.
Perforin expression is constitutive on NK cells, but increases in resting XD8+ cytotoxic cells upon activation.
