Recombinant Human FPRL1 (Formyl Peptide Receptor-Like 1)

WebThe formyl peptide receptors (FPRs) are a group of G protein-coupled chemoattractant receptors that play important roles in host defense and inflammation [ 1, 2 ]. They are so named because their cognate agonists are peptides bearing formylated methionine (fMet), such as those derived from bacterial and mitochondrial proteins [ 3, 4 ]. WebAlthough formylated peptides are the principal agonistic ligands for FPR1, FPR2 can also be activated by cathelicidins, such as human LL37 and murine CRAMP, which are highly cationic antimicrobial proteins stored within the secretory lysosomes of macrophages and neutrophils (Zanetti, 2004).
