basic FUNCTION
  • is an important player in ventral mesencephalic neural fate specification
  • is a novel WNT-dependent transcription factor required for early cortical development and that it may regulate initial cortical patterning by promoting dorsal midline signaling center formation and thereby helping to establish the graded expression of the other transcription regulators of cortical identity
  • plays likely pivotal roles in the early development of the telencephalon via the formation of the cortical hem, a source of WNTs, and also in the maintenance of neural progenitors as a downstream of the WNT pathway
  • DMRTA2 appears to be necessary for proper differentiation of oogonia, prior to entry into meiosis
  • transcription factor key to the development of the dorsal telencephalon
  • plays an important role in maintaining neural progenitor cells (NPCs) in the cell cycle
  • is a novel regulator of the neuron-glia cell-fate switch in the developing hippocampus
    • CELLULAR PROCESS nucleotide, transcription, regulation

  • DMRTA2 upregulates DMRT3 expression and negatively regulates its own expression, which may stabilize the level of DMRTA2, and likely DMRTA2, together with DMRT3, regulate patterning of the cerebral cortex
  • DMRTA2 function is linked to the regulation of HES1 and other proneural genes, as demonstrated by genome-wide RNA-seq and direct binding of DMRTA2 to the HES1 genomic locus
  • link between DMRTA2 modulation of HES1 expression and the maintenance of NPCs during cortical development
  • LHX2 binds a highly conserved putative enhancer of DMRTA2, suggesting an evolutionarily conserved regulatory relationship between these factors
