Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and E-box binding activity. Acts upstream of or within nervous system development and positive regulation of neurogenesis. Predicted to be active in nucleus. Is expressed in several structures, including glioblast; nervous system; neural keel; neural plate; and neural tube. Orthologous to human OLIG2 (oligodendrocyte transcription factor 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
