14. Human pneumococcal glycolytic enzyme enolase, a nonclassical cell surface and plasminogen-binding protein, is a pneumococcal C4BP-binding protein. PMID: 22925928
15. NC4 Domain of cartilage-specific collagen IX inhibits complement directly due to attenuation of membrane attack formation and indirectly through binding and enhancing activity of complement inhibitors C4B-binding protein and factor H. PMID: 21659506
16. C4BP is recruited to the S. aureus surface where it functions to inhibit C4 complement effectors, suggesting a previously undescribed immune evasion strategy for this pathogen. PMID: 22333221
17. Human pentraxin 3 binds to the complement regulator c4b-binding protein. PMID: 21915248
18. Serum C4BP level in 89 patients showed a strong association with the clinical staging of non small cell lung carcinoma. PMID: 21262398
19. C4BPB/C4BPA is a new susceptibility locus for venous thrombosis with unknown protein S-independent mechanism: results from genome-wide association and gene expression analyses followed by case-control studies. PMID: 20212171
20. Binding of the classical pathway inhibitor, C4b-binding protein (C4bp), to three genospecies of B. burgdorferi sensu lato, is demonstrated. PMID: 20022381
21. Data show that C4BP does not bind CD40, but it forms stable high molecular weight complexes with soluble CD40 ligand (sCD154). PMID: 17225862
22. structural requirements for the intracellular subunit polymerization PMID: 12135356
23. Localization of binding sites for a number of C4BP ligands in relation to well-established and novel functions of C4BP. Review PMID: 15179322
24. To determine the regions of C4b contributing to C4BP binding, the binding of the C4c and C4dg subfragments of C4b to C4BP was examined. PMID: 16819837
25. Non-small cell lung cancer (NSCLC) cells produce soluble complement inhibitors factor I (FI) and C4b-binding protein (C4BP). PMID: 17548110
26. The binding sites to Neisseria gonorrhoeae Por1A protein have been mapped within complement control protein domain 1 of C4BP. PMID: 17579075
27. A novel non-synonymous polymorphism (p.Arg240His) in C4b-binding protein is associated with atypical hemolytic uremic syndrome and leads to impaired alternative pathway cofactor activity. PMID: 18424762
28. C4BP binds to dead brain cells and Abeta peptide in vitro, is present in CSF and possibly protects against excessive complement activation in AD brains. PMID: 18556068
29. These results reinforce the case for the occupation of some of the seven arms of C4BP in a multivalent interaction with DNA or surface bound glycosaminoglycans while other arms engage C4b or C3b. PMID: 18715646
30. Mainly the central core of C4BP mediates binding to small leucine-rich repeat proteins (SLRPs). Binding of SLRPs to C4BP does not not affect its ability to inhibit complement. PMID: 19155499
