Rabbit anti-Human LBP Polyclonal Antibody

Uniprot Id

P18428

Target Species

Human

Target Name

LBP

Target Full Name

Lipopolysaccharide-binding protein

Target Function

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.

Target Subcellular Location

Secreted. Cytoplasmic granule membrane.

Target Protein Families

BPI/LBP/Plunc superfamily, BPI/LBP family

Target Tissue Specificity

Detected in blood serum (at protein level).

Target Research Area

Immunology

Target Synonyms

BPI fold containing family D, member 2; Bpifd2; LBP; LBP_HUMAN; LBP1; Lipopolysaccharide binding protein; Lipopolysaccharide-binding protein; LPS binding protein; Ly88; MGC22233; OTTHUMP00000030965; RP23-407H16.4

Target Background

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).
