    basic FUNCTION
  • involved in endothelial dysfunction and atherosclerosis
  • mediating calcium-dependent recognition of phosphatidylserine and apoptotic cells
  • scavenger receptor that plays a central role in the pathogenesis of atherosclerosis
  • cell surface lectin-like receptor for oxidized low density lipoproteins (ox-LDL), plays a pivotal role in host defense resulting from a broad ligand-binding spectrum
  • Ca2+-dependent phospholipid receptor, revealing novel recognition of phospholipids by mammalian lectins
  • promotes growth and migration of macrophages and induces their transformation into foam cells
  • involved in CRP-induced complement activation, and thus may serve to locate the site of CRP-induced complement activation and inflammation
  • crucial role of OLR1 and NFE2L2 in the pathogenesis of preeclampsia
  • may play a crucial role in the pathophysiological processes of intrahepatic cholestasis of pregnancy (ICP) caused by over-apoptosis of trophocytes
  • implicated in cytoskeletal organization and growth of cardiac fibroblasts
  • endothelial scavenger receptor that is important for oxidized low-density lipoprotein uptake
  • contributes, at least in part, to the process of fibroblast senescence and may be viewed as a new aging maker
  • association of CCL2 with OLR1 and LPA may play a role in modulating monocyte trafficking during atherogenesis
  • pivotal role as an immune modulatory protein
    PHYSIOLOGICAL PROCESS cardiovascular
    a component
  • constituent of the NK (natural killer) complex
  • homodimer formed by an intermolecular disulfide bond
    small molecule
  • molecular OLR1/LOXIN interaction and formation of non-functional hetero-oligomers
  • ROCK2 dynamically associate with OLR1 in the presence of Oxidatively modified low-density lipoprotein (OxLDL)
  • stimulates PPARG and subsequently enhances CD36 and inhibits MSR1 in macrophages
  • is the main endothelial receptor for oxidized low density lipoprotein (OxLDL), and is involved in the induction of endothelial dysfunction
  • enhancement of MSR1 via inhibition of PPARG appears to be the most likely basis of sustained ox-LDL uptake in the absence or presence of OLR1
  • OLR1 binds CCL2 and the OLR1-bound CCL2 retains its ability to recruit monocytes
  • promotes migration and adhesion of bone marrow-derived mesenchymal stem cells via regulation of CCL2 expression
  • OLR1 and PCSK9 positively influence each other's expression, especially during an inflammatory reaction
  • is, at least in part, responsible for the inhibitory effect of oxidized low-density lipoprotein (ox-LDL) on macrophage migration and this process involves CAPN1 and CAPN2
  • TICAM1 regulated foam cell formation via regulation of the expression levels of CCL2, F3, OLR1
  • cell & other

    palmitoylated and both cysteine 36 and cysteine 46 were necessary for the recruitment of OLR1 into raft microdomains and for its ligand uptake ability

  • LOX-1 KO mice have low levels of the immunoglobulins in the heart (vs. the WT mice) and the expression of these immunoglobulins in the LOX-1 KO mice is upregulated several-fold when the mice are infused with Angiotensin II
