C4BPB Recombinant Monoclonal Antibody

1. SAA, PROZ, and C4BPB may serve as new potential biomarkers for TB PMID: 28278182
2. Binding of complement inhibitor C4b-binding protein to a highly virulent Streptococcus pyogenes M1 strain is mediated by protein H and enhances adhesion to and invasion of endothelial cells. PMID: 24064215
3. crystallographic data on the structure of CD11c/CD18 and prediction of the secondary structure of the C4BP oligomerization domain, we show that epitopes bound by KIM185 in these proteins are unlikely to share any major structural similarity. PMID: 21856004
4. C4BP alpha7beta0 subunit [C4BP alpha7beta0 isoform lacking the beta-chain] induces a semimature, tolerogenic state on human monocyte-derived dendritic cells activated by a proinflammatory stimulus. PMID: 23390292
5. Since FI requires cofactors for its activity we also investigated the binding of purified cofactors C4BP and FH and found acquisition of both proteins, which retained their activity in FI mediated degradation of C3b and C4b. PMID: 22514678
6. Results demonstrate that successful secretion of complement regulatory protein C4b-binding protein beta-chains depends on intracellular complex formation with vitamin K-dependent protein S, but not on the alpha-chains. PMID: 20693287
7. Localized via protein S to the surface of apoptotic cells, C4BP is able to interact with complement protein C4b, thus retaining its physiological role in regulation of complement on the apoptotic cell surface. PMID: 12193728
8. C4BP is composed of seven alpha-chains and a unique beta-chain, each chain comprising repeating complement control protein (CCP) modules, the results suggest that the role of CCP2 in protein S binding is to orient and stabilize CCP1 PMID: 12492479
9. C4b-binding protein binds to necrotic cells and DNA, limiting DNA release and inhibiting complement activation. PMID: 15967823
10. analysis of structural basis for C4b-binding protein interaction with streptococcal M protein PMID: 16330538
11. review of multiple functional roles of the complex of protein S and cd4-binding protein beta chain, such as binding to apoptotoic cells, phagocytosis PMID: 17597997
12. C4BP levels are increased in patients suffering from primary Sjogren's syndrome PMID: 19284503
