Description: | Bactericidal permeability-increasing protein (BPI) / Lipopolysaccharide-binding protein (LBP) / Cholesteryl ester transfer protein (CETP) C-terminal domain |
Interpro abstract (IPR001124): | This entry represents the C-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 C-terminal domain include:
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 [ (PUBMED:9188532) ]. BPI contains two domains that adopt the same structural fold, even though they have little sequence similarity [ (PUBMED:10843855) ]. Lipopolysaccharide-binding protein (LBP) is an endotoxin-binding protein that is closely related to, and functions in a co-ordinated manner with BPI to facilitate an integrated host response to invading Gram-negative bacteria [ (PUBMED:12887306) ]. Cholesteryl ester transfer protein (CETP) is a glycoprotein that facilitates the transfer of lipids (cholesteryl esters and triglycerides) between the different lipoproteins that transport them through plasma, including HDL, LDL, VLDL and chylomicrons. These lipoproteins shield the lipids from water by encapsulating them within a coating of polar lipids and proteins [ (PUBMED:17277799) ]. Phospholipid transfer protein (PLTP) exchanges phospholipids between lipoproteins and remodels high-density lipoproteins (HDLs) [ (PUBMED:12693940) ]. Palate, lung and nasal epithelium carcinoma-associated protein (PLUNC) is a potential host defensive protein that is secreted from the submucosal gland to the saliva and nasal lavage fluid. PLUNC aapears to be a secreted product of neutrophil granules that participates in an aspect of the inflammatory response that contributes to host defence [ (PUBMED:18245229) ]. Short palate, lung and nasal epithelium clone 1 (SPLUNC1) may bind the lipopolysaccharide of Gram-negative nanobacteria, thereby playing an important role in the host defence of nasopharyngeal epithelium [ (PUBMED:16364440) ]. |
