Recombinant Mouse Complement Component 1, R Subcomponent B, His-tagged

Cat. No. : C1rb-453M
Product Overview : Recombinant Mouse C1rbprotein was expressed in Murine myeloma cell line. Met1-Asn707, witha C terminal 6 His tag.
Description : Theclassical complement pathway plays a major role in innate immunity againstinfection. This pathway is triggered by C1, a multimolecular complex composedof the recognition protein C1q and two serine proteases, C1r and C1s.Following the C1q recognition, C1r is autoactivated, and in turn activatesC1s, which cleaves C4 and C2, the C1 substrates. Both C1r and C1s activationinvolve cleavage of a specific ArgIle bond, converting the singlechain proenzymesinto active proteases composed of disulfidelinked heavy and light chains. Theheavy chain contains multiple domains in the order of CUB1EGFCUB2CCP1CCP2Activation Peptide. The light chain contains the serineprotease catalytic domain.
Source : Murinemyeloma cell line, NS0-derived.
