Activation of C1

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1984
Abstract The first component of complement, C1, is a calcium-dependent complex of two loosely interacting subunits: C1q, responsible for the binding of activators to C1; C1r2—C1s2, which supports the autoactivation potential of C1, together with the proteolytic activity of activated C1 on its two substrates, C4 and C2.

C1s Bound in Macromolecular C1 Exists in Equilibrium with C1s Free in Serum

The Journal of Immunology, 1978
Abstract We have established the existence of an equilibrium between free C1s and C1s bound in macromolecular C1 in human serum. Untreated human sera were incubated for 35 hours at 4°C with 125I-C1s to allow the exchange between free and bound C1s to reach equilibrium.

A Method for Preparing Monospecific Antisera to C1 Esterase (C1s): Microheterogeneity of Purified C1s

The Journal of Immunology, 1970
Abstract Highly purified C1s has been obtained by immunization of rabbits using popliteal node injections of highly purified C1s followed by booster injections with gel segments containing C1s after disc-acrylamide gel electrophoresis.

The Cleavage of Two C1s Subunits by a Single Active C1r Reveals Substantial Flexibility of the C1s-C1r-C1r-C1s Tetramer in the C1 Complex

The Journal of Immunology, 2000
Abstract The activation of the C1s-C1r-C1r-C1s tetramer in the C1 complex, which involves the cleavage of an Arg-Ile bond in the catalytic domains of the subcomponents, is a two-step process. First, the autolytic activation of C1r takes place, then activated C1r cleaves zymogen C1s. The Arg463Gln mutant of C1r (C1rQI) is stabilized in
