Function

FHBP_NEIMB A bacterial surface lipoprotein that binds host (human) complement factor H (fH, gene CFH), binding contributes to the avoidance of complement-mediated lysis by N.meningitidis. Binding of fH to the bacteria surface is independent of bacterial sialic acid moieties (PubMed:16751403). fH binding affinity is high enough that it may sequester plasma fH, depleting its circulating levels and de-regulating complement in the host (Probable). This protein induces high levels of bactericidal antibodies in mice (PubMed:12642606, PubMed:15039331, PubMed:15664958, PubMed:21753121, PubMed:23133374).^{[1] [2] [3] [4] [5] [6] [7]}
