  • early growth response 3 family
  • EGR family of C2H2-type zinc-finger proteins
  • CATEGORY transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • may be a critical regulator of endogenous GABRA4 during development
  • may also plays a role in muscle development
  • transcriptional regulator, essential for normal hippocampal long-term potentiation (LTP) and for hippocampal and amygdala dependent learning and memory
  • has an essential role in learning and memory processing that appears to be partly distinct from the role of EGR1
  • EGR1, EGR2, EGR3, are essential for conversion of the mitogenic signal of epidermal growth factor into a proliferative response
  • is a critical determinant of VEGF signaling in activated endothelial cells
  • transcription factor regulated by NGF signaling in sympathetic neurons that is essential for normal SNS development
  • role for Egr3 in mediating sympathetic target tissue innervation that is independent of neuron survival or neurotrophin deregulation
  • EGR2 and EGR3 regulate B and T cell function in adaptive immune responses and homeostasis by promoting antigen receptor signaling and controlling inflammation
  • nerve growth factor (NGF)-induced transcriptional regulator that is essential for normal sympathetic nervous system development
  • has an essential role in regulating sympathetic neuron dendrite morphology and terminal axon branching, but not in regulating sympathetic axon guidance to their targets
  • EGR2 and EGR3 are the unique regulators for systemic autoimmunity
  • CELLULAR PROCESS nucleotide, transcription, regulation

  • binding GABRA4
  • downstream target for calcineurin
  • BDNF uses CREB1 and EGR3 to regulate NMDA receptor levels in cortical neurons
  • cell & other
    activated by light in the ventral SCN,a structure implicated to "entrainment",i.e the precise adaptation to the 24hlight-dark cycle
    induced by DAG1 and AGRN (AGRN with lamin and DAG1, influence EGR3 levels and therefore may play an important role in spindle fiber differentiation)
    NRG1, that induces expression of the muscle spindle-specific gene EGR3 by stimulating the transcriptional activity of CREB1 and SRF
    Other suppressed by cyclosporin A in T cells

    Therapy target
    represents a potential therapeutic target in VEGF-mediated vasculopathic diseases
  • sensory ataxia and muscle spindle (encapsulated muscle fibers conservated by specialized motor and sensory axons) agenesis,suggesting that type I myotubes are dependent upon Egr3 mediated transcription for proper spindle development
  • germline Egr3-deficient mice have physiologic dysautonomia characterized by apoptotic sympathetic neuron death and abnormal innervation to many target tissues
