Plays a role in the innate immune response. Binds to the lipid A moiety of bacterial lipopolysaccharides (LPS), a glycolipid present in the outer membrane of all Gram-negative bacteria. Acts as an affinity enhancer for CD14, facilitating its association with LPS. Promotes the release of cytokines in response to bacterial lipopolysaccharide. Partial recombinant protein corresponding to aa304-414 from human Lipopolysaccharide-binding protein, fused to 10X His-GST-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E.coli.
