    SUBCELLULAR LOCALIZATION     intracellular
  • translocates to the nucleus in response to EGF-stimulation of certain cell types
  • basic FUNCTION
  • may be functioning as a general coactivator of gene transcription with ligand-independent regulation
  • playing an essential role in the development of midbrain dopamine cells and in the regulation of RET
  • implicated in the development of dopaminergic cells of the ventral tegmental area (VTA) and the substantia nigra (SN)
  • involved in the establishment and maintenance of the dopaminergic phenotype within specific central nervous system neuronal subpopulations including the nigrostriatal dopamine system
  • may also play a role in the pathogenesis of Parkinson disease
  • having a protective function in cartilage homeostasis by selectively repressing MMP gene expression during inflammation
  • plays a pivotal role for mediating cytokine production from pathogenic T cells
  • not only essential in the development of mensencephalic dopaminergic neurons and maintenance of their functions, but it may also play a role in the pathogenesis of Parkinson disease
  • enhances 3,5-cyclic adenosine 5prime-monophosphate-dependent UCP1 gene transcription
  • transcription factor essential for the development, survival, and functional maintenance of midbrain dopaminergic (DAergic) neurons
  • playing a role in neuronal/astrocytic differentiation of neural precursor
  • activating FABP5
  • can enhance RA-induced signaling of PPARbeta/delta and DHA-induced activation of RXR, via the up-regulation of FABP5
  • essential mediator of neuroprotection after exposure to neuropathological stress
  • key downstream mediator of CREB1-induced neuroprotection
  • NR4A1, NR4A2 modulate mesenchymal stromal cell migration
  • induction of NR4A1, NR4A2, NR4A3 in activated mast cells and NR4A family nuclear receptors are implicated in the regulation of mast cell function
  • NR4A2, NR4A1 functions directly at DNA repair sites by a process that requires phosphorylation by PRKDC, and represent an entirely novel component of DNA damage response in the process of DSB repair
  • EGF-stimulation of cells may be a mechanism for the priming of cells for the actions of NR4A2 through increased stability
  • NR4A2 and BDNF show a similar expression pattern during postnatal cerebellar development
  • essential for the nigral dopaminergic neuron phenotype and function maintenance
  • is necessary for both long-term memory for object location and object recognition
  • NR4A1 and NR4A2 differentially contribute to object location versus object recognition memory
  • NR4A1, NR4A2, NR4A3 have key roles in determining CD4(+) T cell fates in the thymus and thus contribute to immune homeostasis
  • functions mainly in transcriptional activation to regulate a battery of genes expressed in dopaminergic neurons
  • regulates key genes, including a battery of nuclear-encoded mitochondrial genes
  • selectively contributes to the maintenance of normal expression levels of nuclear-encoded genes involved in oxidative respiration, but not of any other functional categories of nuclear-encoded mitochondrial genes
  • is an orphan nuclear receptor best known for its essential role in the development and maintenance of midbrain dopaminergic (DA) neurons
  • key midbrain dopamine (mDA) regulators (NR4A2, PITX3, and LMX1A) play overlapping as well as distinct roles during neurogenesis and neurotransmitter phenotype determination of mDA neurons
  • NR4A1, NR4A2, NR4A3 are regulated by different physiological and pathophysiological settings known to be associated with marked alterations in glucose metabolism and energy status
  • plays a key role in embryonic development and maintenance of mesencephalic dopaminergic neurons in the substantia nigra
    a component
  • heterodimerizing with retinoic X receptor (RXR)
  • binding to FABP5 promoter
  • RNA
    small molecule
  • key regulators of CYP11B2 expression and of adrenal aldosterone production
  • cooperating with PITX3 to promote terminal maturation of the midbrain dopamine neuron phenotype in embryonic stem cell cultures
  • association between NR4A2 overexpression and upregulation of CDKN2C, suggesting a mechanism by which NR4A2 could regulate haematopoietic stem cells quiescence
  • NR4A1, NR4A2 interact with PRKDC and, upon exposure to DNA damage, translocate to DSB foci by a mechanism requiring the activity of PARP1
  • potential molecular target of MIR-132 (MIR-132 could directly regulate the expression of NR4A2)
  • is a downstream target of CREB1 and it is responsible for the NMDA-mediated increase in BDNF, which is necessary for the NMDA-mediated prosurvival effect on neurons
  • NR4A2-TOP2B interaction may shed light on the pathologic role of NR4A2 defect in the nigro-striatal pathway deficiency associated with Parkinson disease
  • PIN1 is a novel binding partner of NR4A1, NR4A2, NR4A3
  • in melanoma cells both CRH and UCN1 regulate TYRP1 gene expression via NR4A2/NR4A1 production, independent of pro-opiomelanocortin or alpha-melanocyte-stimulating hormone stimulation
  • NR4A2 represses TH expression via SIRT1 in human neural stem cells
  • FOXA2 acts as a co-activator potentiating expression of the NR4A2-induced dopamine (DA) phenotype via epigenetic regulation
  • PTH activates the orphan nuclear receptor NR4A2 to induce FGF23 transcription
  • NR4A2 is an orphan transcription factor that influences the expression of several key proteins of dopaminergic (DA) neurons, including tyrosine hydroxylase (TH), dopamine transporter (SLC6A3), and vesicular monoamine transporter (SLC18A1)
