WebPerforin is a monomeric pore-forming protein that is inactive when located within granules, but undergoes a conformational activation, which is Ca2 + dependent. It is related both structurally and functionally to the complement component C9, which forms the membrane attack complex. Web(A) Direct CTL-mediated killing requires cell–cell contact and commonly results from the release of cytolytic enzymes such as granzyme B. Perforin, released by the CTL, forms pores in the membrane of a juxtaposed target cell allowing passive inward diffusion of granzyme B, which then triggers apoptosis of the targeted cell.
