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. Interacts with STEAP3. Mostly in developing nervous system. Expressed in neural progenitors and oligodendrocyte lineage cells. More highly expressed in oligodendrocyte progenitors than in differentiated oligodendrocytes. 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.
