Background
Human Complement Component 7 (C7) is an 821 amino acid (aa) single-chain glycoprotein with a molecular weight of about 92.4 KD. The N terminus of C7 shares 23-30% aa sequence identity with human Complement Components C8 and C9. C7 is essential for formation of the membrane attack complex (MAC) and is activated non-proteolytically by binding to recently-formed C5b, C6 complexes at the cell membrane. C7 is one of five complement proteins C5b, C6, C7, C8, and C9 that assemble on pathogen membranes to form the lethal membrane attack complex. It serves as a membrane anchor for the C5b-7 complex. C7 deficiency exhibits an increased susceptibility to Neisseria meningitides infections and recurrent meningococcal disease.
