    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • may be acting as a transcriptional activator
  • modulating vascular smooth muscle cell proliferation
  • playing a role in spontaneous and accelerated atherosclerosis
  • required for T-cells receptor mediated apoptosis of immature thymocytes
  • playing a necessary role for oxidative metabolism in skeletal muscle
  • its up-regulation plays a key role in thrombin-induced endothelial cell growth
  • mediating vascular smooth muscle cell proliferation
  • is involved in the regulation of the survival response of endothelial cells to hypoxia via the upregulation of CIAP2
  • downstream effector of HIF-1 signaling
  • essential mediator of neuroprotection after exposure to neuropathological stress
  • key downstream mediator of CREB1-induced neuroprotection
  • mediates monocyte adhesion by inducing VCAM1 and intercellular adhesion molecule-1 expression in endothelial cells
  • induction of NR4A1, NR4A2, NR4A3 in activated mast cells and NR4A family nuclear receptors are implicated in the regulation of mast cell function
  • is a novel positive transcriptional regulator of SKP2 expression and downstream CDKN1B degradation in vascular smooth muscle cells
  • specific requirement of NR4A3 for SKP2 expression during neointima formation in response to vascular injury
  • NR4A1, NR4A2, NR4A3 have key roles in determining CD4(+) T cell fates in the thymus and thus contribute to immune homeostasis
  • NR4A1, NR4A2, NR4A3 are regulated by different physiological and pathophysiological settings known to be associated with marked alterations in glucose metabolism and energy status

  • direct target of RUNX1 and restoration of NR4A3 expression in acute myelogenous leukemia partially reduced the clonogenic potential of patient progenitors
  • SKP2 is a direct transcriptional target for NR4A1
  • PIN1 is a novel binding partner of NR4A1, NR4A2, NR4A3
  • mutual antagonism between NR4A3 and NR3C1 to be a key rheostat for peripheral metabolic signals to centrally control energy balance
  • NKX6-1 induces expression of NR4A1 and NR4A3 orphan nuclear receptors, and these factors are both necessary and sufficient for NKX6-1-mediated beta-cell proliferation

    Variant & Polymorphism
    Candidate gene
  • pathognomic rearrangement of NR4A3 is a useful diagnostic feature in identifying cellular extraskeletal myxoid chondrosarcoma
  • Therapy target
    blockage of NR4A3 could be useful to prevent vascular effects triggered by thrombin
    identification of pro-apoptotic agents inducing NR4A expression or acting as agonists suggests that these members could serve as potential targets for cancer therapy
  • expression increased in diabetic mice that exhibit elevated gluconeogenesis
  • Nor1 deficiency reduces hypercholesterolemia-induced atherosclerosis formation in apoE(-/-) mice by decreasing the macrophage content of the lesion
