  • seven transmembrane segments (7 TM) receptor
    interspecies homolog to murine Cmklr1
  • G-protein coupled receptor 1 family
  • CATEGORY receptor membrane G
    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • orphan receptor playing a role in bone metabolism
  • could be a chemotactic peptide receptor
  • may have a function in bone metabolism
  • acting as a coreceptor for immunodeficiency viruses that does not belong to the chemokine receptor family
  • playing a role in the mediation of the autocrine/paracrine effects of chemerin
  • serpentine receptor expressed by mononuclear phagocytes and dendritic cells
  • playing a role in the recruitment of blood NK cells and its ligand chemerin is a key factor for the colocalization of NK cells and dendritic cells subsets in pathologic peripheral tissues
  • potential critical role for CMKLR1:chemerin in shaping the nature (either proinflammatory or suppressive) in macrophage-mediated immune responses
  • involved in chemerin induced inflammatory response/chemotaxis and specific recruitment of antigen-presenting cells to inflammatory sites
  • regulates skeletal muscle cell myogenesis
  • roles for RARRES2/CMKLR1-mediated in dental epithelial-dental mesenchymal (DE-DM) signaling during tooth morphogenesis
  • G protein-coupled receptor found on select immune, epithelial, and dorsal root ganglion/spinal cord neuronal cells
  • role of CMKLR1 in the attraction of macrophages to inflamed tissue by RARRES2 and in the initiation of resolution of inflammation through resolvin E1-mediated repolarization of human M1 macrophages toward resolution-type macrophages
  • is a novel WNT responsive gene that functions in a negative feedback loop to limit osteoblastogenic WNT signaling
  • CMKLR1 exacerbated the proliferation and migration of vascular smooth muscle cells (VSMCs) by activating MAPK3/MAPK1
    a component RARRES2/CMKLR1 system has been implicated in mediating cellular migration under inflammatory condition
    small molecule
  • binding chemerin (RARRES2) on macrophages and plasmacytoid dendritic cells, and promotes chemotaxis
  • also serves as a receptor for resolvins and lipoxins
  • plasma protein-derived chemoattractant chemerin is a ligand for CMKLR1 and activation of CMKLR1 with chemerin induces the migration of macrophages and dendritic cells, suggesting a proinflammatory role
  • CCRL2 binds chemerin and increases local chemerin concentration to efficiently present it to CMKLR1 on nearby cells, providing a link between CCRL2 and CMKLR1
  • proteolytic activation of CMKLR1 by KLK7 breaks an ionic linkage and results in C-terminal rearrangement
  • is a new addition to the repertoire of cell surface molecules that are responsible for APP processing and clearance
  • cell & other
    activated by both lipid and peptide agonists, resolvin E1 and RARRES2, respectively

  • mesenchymal stem cell (MSC) from Cmklr1 knockout (-/-) mice exhibited similar dependency on Notch signaling to maintain osteoblastogenic differentiation
  • Cmklr1 null mice have a subtle skeletal muscle deficit beginning from embryonic life that persists during postnatal life
