    basic FUNCTION
  • playing a role in transcriptional repression in the central nervous system
  • may play an important role in brain development and function
  • potentially controls cell division of progenitor cells and regulates the survival of postmitotic cortical neurons
  • is expressed in postmitotic brain cells and inhibits brain tumor growth
  • is involved in control of neuronal progenitor cells and survival of cortical neurons, and is implicated with CEP170 as novel genes causative for corpus callosal abnormalities in patients with a terminal 1q deletion
  • may act to favor neuronal differentiation and brain growth by coherently repressing multiple proneurogenic genes in a timely manner
  • key regulator that controls the self-renewal and differentiation of neural stem cells (NSCs) and restriction of astrogenesis by repressing ID1, ID2, ID3, ID4 genes during corticogenesis
  • is essential for the growth and organization of the cerebellum and regulates the development of both GABAergic and glutamatergic neurons
  • key regulator of neuronal migration via multipolar-to-bipolar transition
  • functions in cell-autonomous multipolar-to-bipolar transition, independent of cell-cycle exit
  • is a key player in the transcriptional control of cell migration in the developing cerebral cortex

    protein
  • recruiting DNMT3A to HDAC1 to silence transcription
  • NEUROG2 is a direct upstream activator of ZBTB18 expression
  • ZBTB18 represses NEUROG2 transcription to regulate the NEUROG2-RND2 pathway
  • negative regulation of RND2 by ZNF238 was important for cortical cell migration
  • CTBP2 interacted with ZBTB18 to affect biological characteristics of GBM cells, and the tumor growth, which may be related to the SHH-GLI1 pathway
