Summary: Enables DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; and identical protein binding activity. Involved in negative regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including adult feeding behavior; adult locomotory behavior; and brain development. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; central nervous system; embryo ectoderm; limb bud; and sensory organ. Orthologous to human DMBX1 (diencephalon/mesencephalon homeobox 1). [provided by Alliance of Genome Resources, Apr 2022]

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.
