We identified a novel, homozygous, loss-of-function mutation (p.Pro445Leufs*11) in the C1R gene. Using the Sanger method of DNA sequencing in 14 family members, we confirmed the presence of the mutation in 4 patients with early-onset systemic lupus erythematosus and in an asymptomatic 9-year-old girl. Complement levels were low in sera from patients with truncated C1r protein.
Periodontal Ehlers-Danlos Syndrome in at least the great majority of cases results from specific classes of heterozygous mutations in C1R and C1S (show C1S ELISA Kits).
We confirmed increased levels of C1R and VTN (show VTN ELISA Kits) in sera from patients with Joint hypermobility syndrome by western blot analyses
C1q exists as the C1 complex (C1qC1r2C1s2), and C1q binding to ligands activates the C1r/C1s (show C1S ELISA Kits) proteases. Incubation of nucleoli with C1 caused degradation of the nucleolar proteins nucleolin (show NCL ELISA Kits) and nucleophosmin 1 (show NPM1 ELISA Kits). T
C1r specificity is well suited to its cleavage targets and that efficient cleavage of C1s (show C1S ELISA Kits) is achieved through both active site and exosite contributions.
Analysis of its interaction properties by surface plasmon resonance shows that rC1q retains the ability of serum C1q to associate with the C1s (show C1S ELISA Kits)-C1r-C1r-C1s (show C1S ELISA Kits) tetramer, to recognize physiological C1q ligands such as IgG and pentraxin 3 (show PTX3 ELISA Kits)
a structural rearrangement as a switch between functional states of human C1r
These results provide further structural insights into the architecture of the C1 complex, and the interactions between C1r and C1s (show C1S ELISA Kits).
The modular C1r protein is the first protease activated in the classical complement pathway, a key component of innate immunity.
Detailed mapping of C1q post-translational modifications and insights into the C1r/C1s (show C1S ELISA Kits) binding sites.
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.
