Proteins containing this N-terminal ...This entry represents the N-terminal domain found in several lipid-binding serum glycoproteins. The N- and C-terminal domains share a similar two-layer alpha/beta structure, but they show little sequence identity. Proteins containing this N-terminal domain include: Bactericidal permeability-increasing protein (BPI), Lipopolysaccharide-binding protein (LBP), Cholesteryl ester transfer protein (CETP), Phospholipid transfer protein (PLTP), Palate, lung and nasal epithelium carcinoma-associated protein (PLUNC). Bactericidal permeability-increasing protein (BPI) is a potent antimicrobial protein of 456 residues that binds to and neutralises lipopolysaccharides from the outer membrane of Gram-negative bacteria [1]. BPI contains two domains that adopt the same structural fold, even though they have little sequence similarity [2].
