- Lipopolysaccharide-binding protein
Lipopolysaccharide binding protein, also known as LBP, is a human
gene .cite web | title = Entrez Gene: LBP lipopolysaccharide binding protein| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=3929| accessdate = ]LBP is a soluble
acute phase protein that binds to bacteriallipopolysaccharide (or LPS) to elicit immune responses by presenting the LPS to important cell surfacepattern recognition receptor s calledCD14 and TLR4.

section_title =
summary_text = The protein encoded by this gene is involved in the acute-phase immunologic response to gram-negative bacterial infections. Gram-negative bacteria contain a glycolipid, lipopolysaccharide (LPS), on their outer cell wall. Together with bactericidal permeability-increasing protein (BPI), the encoded protein binds LPS and interacts with the CD14 receptor, probably playing a role in regulating LPS-dependent monocyte responses. Studies in mice suggest that the encoded protein is necessary for the rapid acute-phase response to LPS but not for the clearance of LPS from circulation. This protein is part of a family of structurally and functionally related proteins, including BPI, plasma cholesteryl ester transfer protein (CETP), and phospholipid transfer protein (PLTP). Finally, this gene is found on chromosome 20, immediately downstream of the BPI gene.cite web | title = Entrez Gene: LBP lipopolysaccharide binding protein| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=3929| accessdate = ]References
