Summary: Enables DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and identical protein binding activity. Acts upstream of or within several processes, including nervous system development; regulation of transcription by RNA polymerase II; and suckling behavior. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including brain; future midbrain; genitourinary system; mandible; and nose. Orthologous to human HELT (helt bHLH transcription factor). [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.
