Background
C1 is the first complement component in the classical pathway of complement. C1 binds to and is activated by antibodies bound to antigens (immune complexes) yielding a protease that initiates the cascade. C1 is actually a non-covalent complex of three different proteins (C1q, C1r and C1s) bound together in a calcium-dependent complex. The globular heads of the C1q bind to the Fc-fragment of IgM or IgG on the surface of a pathogen, resulting in the activation of C1r. The activated C1r is able to activate C1s which in turn activates C2 and C4, leading to the production of the C4b-C2a form of C3-convertase. C1 deficiency is generally associated with severe immune complex disease of systemic lupus erythematosus and glomerulonephritis.
