Target

  • Function
    Transcription factor that activates the expression of the EIF2S1 (EIF2-alpha) gene. Links the transcriptional modulation of key metabolic genes to cellular growth and development. Implicated in the control of nuclear genes required for respiration, heme biosynthesis, and mitochondrial DNA transcription and replication.
  • Tissue specificity
    Ubiquitously expressed with strongest expression in skeletal muscle.
  • Sequence similarities
    Belongs to the NRF1/Ewg family.
  • Post-translational
    modifications
    Phosphorylation enhances DNA binding.
  • Cellular localization
    Nucleus.
