N formyl Hexapeptide Receptor

A Family of G-Protein-Coupled Receptors that was originally identified by its ability to bind N-formyl Peptides such as N-Formylmethionine Leucyl-Phenylalanine. Since N-formyl Peptides are found in Mitochondria and Bacteria, this class of receptors is believed to play a Role in mediating cellular responses to cellular damage and Bacterial invasion. However, non-formylated peptide Ligands have also been found for this receptor class.
