anti-BPI antibody
The antimicrobial protein BPI is a 55kD protein found in the primary (azurophilic) granules of human neutrophils and has also been detected on surface of neutrophils, small intestinal and oral epithelial cells. BPI is a bactericidal compound that is present in polymorphonuclear cells (PMN) and in lower levels in the specific granules of eosinophils. BPI possesses high affinity toward the lipid A region of lipopolysaccharides (LPS) that comprise the outer leaflet of the gram-negative bacterial outer membrane. Binding of BPI to the lipid A moiety of LPS exerts multiple anti-infective activities against gram-negative bacteria: 1) cytotoxicity via sequential damage to bacterial outer and inner lipid membranes, 2) neutralization of gram-negative bacterial LPS, 3) opsonization of bacteria to enhance phagocytosis by neutrophils. Airway epithelial cells constitutively express the BPI gene and produce the BPI protein and, therefore, BPI may be a critical determinant in the development of LPS-triggered airways disease. Inflammation induced by LPS possibly contributes to the development of rapid airflow decline, a serious and often fatal complication of hematopoietic cell transplantation. Furthermore, a 21kD bioactive recombinant fragment of BPI, rBPI21, was shown to confer a survival advantage

UniProt Comments for BPI
Function: The cytotoxic action of BPI is limited to many species of Gram-negative bacteria; this specificity may be explained by a strong affinity of the very basic N-terminal half for the negatively charged lipopolysaccharides that are unique to the Gram-negative bacterial outer envelope.

Subunit structure: Monomer. Homodimer; disulfide-linked

Subcellular location: Secreted

By similarity. Cytoplasmic granule membrane

By similarity. Note: Membrane-associated in polymorphonuclear Leukocytes (PMN) granules

Tissue specificity: Restricted to cells of the myeloid series.

Domain: The N-terminal region may be exposed to the interior of the granule, whereas the C-terminal portion may be embedded in the membrane. During phagocytosis and degranulation, proteases may be released and activated and cleave BPI at the junction of the N- and C-terminal portions of the molecule, providing controlled release of the N-terminal antibacterial fragment when bacteria are ingested

Sequence similarities: Belongs to the BPI/LBP/Plunc superfamily. BPI/LBP family.
