Binds to the promoter region of genes encoding proteolipid proteins of the central nervous system. May play a role in the development of neurons and oligodendroglia in the CNS. May regulate a critical transition point in oligodendrocyte lineage development by modulating oligodendrocyte progenitor proliferation relative to terminal differentiation and up-regulation of myelin gene transcription (By similarity). Interacts with STEAP3. Isoform 1 is more predominant than isoform 2 at all stages of development and adulthood. Expressed in differentiated neurons especially at higher levels in newly generated ones. Isoform 1 is detected in the earliest born neurons. At 9.5 dpc it is detected in the ventrolateral part of the spinal cord, which later become motor neurons and is also detected in the dispersed cells of the alar plate interneurons. During spinal cord development, the expression is highest in the latest born neurons (the subventricular zone). Detected in the early differentiated neurons within the neuroepithelium and the neural crest cells at 9.5 dpc. At 12.5 dpc, detected in the differentiated neurons within the forebrain, midbrain, and hindbrain. In these neurons, the expression level is highest in the latest born neurons and is also detected in the differentiated neurons of the sensory organs and the peripheral ganglia. Contains 7 zinc fingers of the C2HC class arranged in two widely separated clusters. These two domains of DNA binding can function independently and recognize the same DNA sequence. Belongs to the MYT1 family.
