  • basic FUNCTION
  • acting as a transcriptional repressor
  • involved in lymphoid malignancies through either chromosomal translocation or amplification
  • playing a direct role in globin gene regulation
  • might influence globin gene expression either directly by interacting with cis-regulatory elements within the beta-globin cluster or indirectly by affecting cell cycle or other pathways that ultimately impinge on HbF expression
  • may function as a modulator of the transcriptional repression activity of ARP1
  • functioning as a myeloid and B-cell proto-oncogene
  • central mediator of gamma-globin silencing and hemoglobin switching
  • repressor of gamma-globin gene expression in adult erythroid progenitors
  • is a critical component of a transcriptional network that regulates B cell fate by controlling V(D)J recombination
  • critical modulator of hemoglobin switching and HbF silencing

  • important role for the KLF1-BCL11A axis in erythroid maturation and developmental regulation of globin expression
  • transcription factor known to regulate lymphoid and erythroid developmen

  • is a novel NR2E1 coregulator that might be involved in NR2E1-dependent gene regulation in the brain
  • is essential for lymphopoiesis and negatively regulates TP53 activities
  • KDM1A/RCOR1 histone demethylase complex interacts with BCL11A and is required for full developmental silencing of gamma-globin genes in adult erythroid cells
