Gene Information

human ... BPI(671)

General description

BPI (Bactericidal permeability-increasing protein) gene is mapped on to human chromosome 20q11.23. It belongs to the family of lipid-transfer proteins. BPI is mainly present in the granules of neutrophils and on the surface of neutrophils and monocytes.

Immunogen

synthetic peptide corresponding to amino acids 61-75 of human BPI

Application

Anti-BPI (61-75) antibody produced in rabbit has been used in immunoprecipitation.

Biochem/physiol Actions

BPI gene encodes a membrane associated bactericidal permeability increasing protein. BPI possesses high affinity for lipopolysaccharide. It has antimicrobial activity against gram-negative organisms and is essential constituent of the innate immune system for destroying the microbes as well as modulates subsequent adaptive immune responses. The amino-terminal of BPI is responsible for antimicrobial cytotoxicity and endotoxin-neutralization. The carboxyl-terminal is mainly for BPI-dependent transfer of Gram-negative bacteria and cell free endotoxin-rich particles to specific host cells. Mutation in BPI gene or a decrease of plasma BPI level may lead to chronic obstructive pulmonary disease (acute pneumonia and cystic fibrosis).

Target description

BPI (61-75), bactericidal/permeability-increasing protein, encodes a lipopolysaccharide binding protein. It is associated with human neutrophil granules and has bactericidal activity on gram-negative organisms.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Neutrophils contain granules loaded with antimicrobial proteins and are regarded as impermeable organelles that deliver cargo via membrane fusion. However, during the formation of neutrophil extracellular traps (NETs), neutrophil elastase (NE) translocates from the granules to the nucleus via an

Gram-negative bacteria (GNB) and their endotoxin present a constant environmental challenge. Endotoxins can potently signal mobilization of host defenses against invading GNB but also potentially induce severe pathophysiology, necessitating controlled initiation and resolution of endotoxin-induced inflammation to maintain host integrity.
