Target Details for FPR2

Target: FPR2 (Formyl Peptide Receptor 2 (FPR2))

Alternative Name: FPR2

Background: N-formyl peptide receptor 2, FMLP-related receptor I, FMLPX, Formyl peptide receptor-like 1, FPRL1, ALXR, Lipoxin A4 receptor, LXA4 receptor, LXA4R, RFP,Chemotactic factors from both Gram-positive and Gram-negative bacteria are short peptides with N-formyl methionine at the N-terminus (extensively reviewed in reference 1). These peptides are released from bacteria during infection and activate formyl peptide receptors (FPR), members of the G-protein coupled receptor (GPCR) superfamily. In humans, the FPR family consists mainly of three receptors, FPR1, FPR2/ALX (formerly FPRL1), and FPR3 (formerly FPRL2) which all couple to the Gi subtype of G-proteins and ultimately lead to the activation of phospholipase C and intracellular Ca2+ increase1,2.FPRL1, or FPR2/ALX as it is commonly called, is a seven transmembrane protein like all GPCRs. This receptor was originally cloned by screening a HL60 neutrophil cDNA library with a FPR1 cDNA probe3. FPR2/ALX shares 69 % identity with FPR1 and despite its high homology, it displays relatively low affinity for fmlf, the most potent N-formyl peptide released by bacteria3.FPR1 was originally found in neutrophils and later found to be distributed in myeloid and non-myeloid cells as is the case for FPR2/ALX and FPR3 (FPR3 though is not expressed in neutrophils). FPR1 is also expressed in multiple organs and tissues including epithelial cells in organs with secretory functions, endocrine cells, liver hepathocytes, smooth muscle cells and endothelial cells, brain spinal cord and both motor and sensory neurons4. FPR2/ALX has a similar tissue distribution to that of FPR1.While N-formyl peptides were the first peptides found to activate these receptors, the ligand diversity for FPR has proven to be quite broad and demonstrates to be both pro- and anti-inflammatory. They include peptidic ligands originating from bacterial and viral sources (including HIV), endogenous ligands such as chemokines and annexins, short peptides associated with inflammation and infection. Interestingly, β-amyloid peptide, a known marker for Alzheimer's disease activates FPR2/ALX thereby directly linking these receptors to the neurodegenerative disease. Lipoxin A4 (LXA4) is the first identified endogenous ligand for FPR2/ALX and is an eicosanoid with potent anti-inflammatory characteristics1.Considering that FPR2/ALX can be activated by two different types of ligands, this receptor can be categorized in two different GPCR subgroups: Formyl peptide receptors and Leukotriene receptors.
