Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and E-box binding activity. Involved in oligodendrocyte development. Acts upstream of or within neuron fate commitment. Predicted to be part of transcription regulator complex. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; embryo mesenchyme; future diencephalon; sensory organ; and testis.

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.
