    basic FUNCTION
  • positively regulating the genes under the control of corticotropin-releasing hormone (CRM) and CRM II promoters
  • playing a role in mammalian neurogenesis by regulating their diverse patterns of gene expression
  • BRN2 and its phosphorylation are involved in the migration and proliferation of cells of the melanocyte lineage
  • POU3F3 and POU3F2 (Brn1 and Brn2) are known to label postmitotic upper-layer cells, and are redundantly required for their production
  • important for hypothalamic development and function, and controls oxytocin expression in the hypothalamic neuroendocrine preoptic area

    INTERACTION
    DNA
  • binding prefenrentially to the recognition sequence consisting of two distinct half sites (GCAT and TAAT), separated by a non-conserved spacer region of 0 or 2 or 3 nucleotides
  • binding to the octamer sequence ATGCAAAT
  • RNA
    small molecule
    protein
  • class III POU factor Brn-4
  • PQBP1
  • POU3F2, POU3F3 influence multiple stages of neurogenesis by suppressing Notch effector HES5, and promoting the expression of proneural transcription factors EOMES and TBR1
  • in the astrocyte lineage, ZBTB20 directly represses the expression of POU3F2, which encodes a protein necessary for upper-layer neuron specification
