The formylpeptide receptors (nomenclature agreed by the NC-IUPHAR Subcommittee on the formylpeptide receptor family [26]) respond to exogenous ligands such as the bacterial product fMet-Leu-Phe (fMLP) and endogenous ligands such as annexin I (ANXA1, P04083) , cathepsin G (CTSG, P08311), amyloid β42, serum amyloid A and spinorphin, derived from β-haemoglobin (HBB, P68871).

Note that the data for FPR2/ALX are also reproduced on the leukotriene receptor page.
