    basic FUNCTION
  • mediating chemotaxis and inducing leukocyte activation
  • receptor for n-formyl-methionyl peptides, which are powerful neutrophils chemotactic factors
  • novel role for FPR1 stimulation in enhancing intestinal epithelial cell restitution through PI3K-dependent activation of RAC1 and CDC42
  • expression of FPR1 in myeloid cells is developmentally regulated
  • lens epithelial cell FPR1 may be involved in development and maintenance of the lens
  • role for FPR1 to chemotaxis and superoxide production of resting and pro-inflammatory M1 macrophages
  • fundamental difference between the two neutrophil FPR1 and FPR2, regarding their sensitivities to third intracellular loop pepducins
  • FPR1, FPR2, FPR3, are critical for normal healing of the sterile skin wound by mediating the first wave of neutrophil infiltration
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • FPR2 might exist as homo- or heterodimer with FPR1 or FPR3 (the two other family members) and operate in a ligand-biased fashion
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • coupling with Gs alpha protein and activating adenylate cyclase, leukocyte membrane glycoprotein
  • possible signaling role for ANXA1 in mitogen-activated proliferation of breast tumor epithelial cells that is mediated via activation of FPR1 and FPR2
  • different structural determinants are used by FPR1 and FPR2 to interact with formyl peptides
