The membrane attack complex (MAC) or terminal complement complex (TCC) is a complex of proteins typically formed on the surface of pathogen cell membranes as a result of the activation of the host's complement system, and as such is an effector of the immune system. Antibody-mediated … See more MAC is composed of a complex of four complement proteins (C5b, C6, C7, and C8) that bind to the outer surface of the plasma membrane, and many copies of a fifth protein (C9) that hook up to one another, forming a … See more Similar hydrophobic sites on C8 and C9 molecules are exposed when they bind to the complex, so they can also insert into the bilayer. See more Deficiencies of C5 to C9 components do not lead to a generalized susceptibility to infections but only to an increased susceptibility to Neisseria infections, since Neisseria have a thin See more • Media related to Complement membrane attack complex at Wikimedia Commons • Complement+Membrane+Attack+Complex at the U.S. National Library of Medicine Medical Subject Headings See more The membrane attack complex is initiated when the complement protein C5 convertase cleaves C5 into C5a and C5b.
