The complement system is part of our innate immune system. The classical complement pathway is triggered by activation of the C1 initiation complex upon binding to cell surfaces. C1, or C1qr2s2, consists of four proteases, C1r and C1s, that associate with C1q, which contains antibody-binding sites.|The reconstruction reveals densities for all C1q collagen-like triple helices and gC1q modules, C1r and C1s proteases |
