Also known as: sox21; sox25; sox30; SRY-box
Summary: Enables DNA binding activity and DNA-binding transcription factor activity, RNA polymerase II-specific. Involved in dorsal/ventral pattern formation and negative regulation of transcription by RNA polymerase II. Acts upstream of or within response to steroid hormone. Predicted to be active in nucleus. Is expressed in several structures, including hindbrain neural plate; nervous system; neural rod; neural tube; and pleuroperitoneal region. Orthologous to human SOX21 (SRY-box transcription factor 21). [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.
