MeSH definition : A calcium-dependent pore-forming protein synthesized in cytolytic LYMPHOCYTES and
sequestered in secretory granules. Upon immunological reaction between a cytolytic
lymphocyte and a target cell, perforin is released at the plasma membrane and polymerizes
into transmembrane tubules (forming pores) which lead to death of a target cell.;
