Related Product Information for
anti-C1R antibody
C1r B chain is a serine protease that combines with C1q and C1s to form C1, the first component of the classical pathway of the complement system. C1r is a single-chain glycoprotein which can be cleaved into an A chain and a B chain upon activation. This antibody recognizes full-length C1r chain and the cleaved B chain.

NCBI Summary for C1R
This gene encodes a member of the peptidase S1 protein family. The encoded protein is a proteolytic subunit in the complement system C1 complex. The complement system acts as a mediator in the innate immune response by ultimately triggering phagocytosis, inflammation, and rupturing the bacterial cell wall. Mutations in this gene are associated with Ehlers-Danlos Syndrome. [provided by RefSeq, Dec 2018]

Research Articles on C1R
1. The serine protease domains of C1r and C1s are at the periphery of the C1r2s2 tetramer both when alone or within the nonactivated C1 complex. The C1 complex adopts a conformation incompatible with intramolecular activation of C1. Instead, intermolecular proteolytic activation between neighboring C1 complexes bound to a complement-activating surface occurs. Many structurally unrelated molecular patterns can activate C1.
