Synthesis and Biological Activity of Transmembrane Peptides Derived from FPR Family Receptors
Receptors, translocators and membrane enzymes exist as membrane integral proteins upon cellular surface. They are known to function as dimers or even higher oligomers. It is reported that transmembrane (TM) peptides derived from membrane integral protein modulated dimerization and consecutive function of parent proteins . Neutrophils act as the first line of defense against the invasion of microorganisms in the body. Bacterial metabolites such as N-formylmethionyl peptides are chemoattractants for neutrophils and bind to specific surface receptors, N-formyl peptide receptor (FPR) that trigger specific host defensive processes such as chemotactic migration and killing of microorganisms through superoxide and phagocytosis. Human FPR was first defined biochemically in 1976, as a high-affinity binding site on the surface of neutrophils for prototypic N-formyl peptide, formyl-Met-Leu-Phe-OH (fMLP) . FPR has the structure of seven membrane-spanning α-helical domains, and...
