Formyl peptide receptor

The formyl peptide receptors are a members of a class of G protein-coupled receptors involved in chemotaxis. These receptors where originally identified by their ability to bind N-formyl peptides such as N-formylmethionine produced by the degradation of either bacterial or host cells. Hence formyl peptide receptors are involved in mediating immune cell response to infection. These receptors may also act to suppress the immune system under certain conditions.
