Summary: Enables DNA-binding transcription factor activity and sequence-specific DNA binding activity. Acts upstream of or within several processes, including central nervous system myelination; pancreatic A cell differentiation; and regulation of oligodendrocyte differentiation. Located in nucleus. Is expressed in several structures, including 4-cell stage embryo; central nervous system; gut; neural ectoderm; and thymus. Human ortholog(s) of this gene implicated in spastic ataxia 8. Orthologous to human NKX6-2 (NK6 homeobox 2). [provided by Alliance of Genome Resources, Dec 2024]

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.
