Previous GeneCards Identifiers for FPR1 Gene
This gene encodes a G protein-coupled receptor of mammalian phagocytic cells that is a member of the G-protein coupled receptor 1 family. The protein mediates the response of phagocytic cells to invasion of the host by microorganisms and is important in host defense and inflammation.[provided by RefSeq, Jul 2010]
GeneCards Summary for FPR1 Gene
FPR1 (Formyl Peptide Receptor 1) is a Protein Coding gene. Diseases associated with FPR1 include Susceptibility To Localized Juvenile Periodontitis and Periodontitis. Among its related pathways are Signaling by GPCR and Peptide ligand-binding receptors. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and RAGE receptor binding. An important paralog of this gene is FPR2.
UniProtKB/Swiss-Prot Summary for FPR1 Gene
High affinity receptor for N-formyl-methionyl peptides (fMLP), which are powerful neutrophil chemotactic factors (PubMed:2161213, PubMed:2176894, PubMed:10514456, PubMed:15153520). Binding of fMLP to the receptor stimulates intracellular calcium mobilization and superoxide anion release (PubMed:2161213, PubMed:1712023, PubMed:15153520). This response is mediated via a G-protein that activates a phosphatidylinositol-calcium second messenger system (PubMed:1712023, PubMed:10514456). Receptor for TAFA4, mediates its effects on chemoattracting macrophages, promoting phagocytosis and increasing ROS release (PubMed:25109685).
The formyl peptide receptor family, FPR1, FPR2 and FPR3 (formerly FPR, FPRL1 and FPRL2 respectively) are Gi-protein-coupled receptors that are expressed mainly by mammalian phagocytic leukocytes. FPRs are involved in antibacterial host defence and inflammation.
