 FPR3).FPR2 and FPR3 are termed formyl peptide receptors base on the similarities of their amino acid sequences to that of FPR1 rather than any preferences for binding formyl peptides.Indeed, FPR2 prefers a very different set of ligands and has some very different functions than FPR1 while FPR3 does not bind FMLP or many other N-formyl peptides which bind to FPR1 or FPR2.
