Formyl peptide receptors (FPR) are G protein-coupled receptors that are activated by different agonists included N- formylated peptides originating from bacteria and mitochondria. In humans, the FPR family includes the high affinity FPR1, the low affinity FPR2/ALX (previously known as FPRL1 or ALX) and FPR3. Human FPR1 is important for phagocyte chemotaxis, superoxide production, and degranulation, and helps direct phagocytes to sites of infection. Functional FPR1expression has been demonstrated on fibroblasts, bone marrow mesenchymal stem cells, A549 lung cells, HEP-G2 hepatoma cells, and on several types of epithelial cells. FPR2 (Formyl Peptide Receptor 2) is a Protein Coding gene. Diseases associated with FPR2 include Diamond-Blackfan Anemia 2 and Prion Disease. Among its related pathways are Class A/1 (Rhodopsin-like receptors) and GPCR downstream signalling. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and N-formyl peptide receptor activity. An important paralog of this gene is FPR3.
