    basic FUNCTION
  • playing a role in the extension of neurite-type cytoplasmic processes in developing cells
  • its expression leads to the abrogation of REST-mediated transcriptional repression and the resultant activation of neuronal-specific genes
  • HMG-domain protein, having a key role in the initiation of neuronal differentiation, through recruitment of MLL
  • activates REST (RE-1 silencing transcription factor)-responsive genes, playing a key role in the initiation of neuronal differentiation
  • CELLULAR PROCESS nucleotide, transcription
