Summary
Enables DNA-binding transcription factor activity and double-stranded DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Is expressed in brain; liver; spinal cord; and testis. Orthologous to human SP1 (Sp1 transcription factor). [provided by Alliance of Genome Resources, Apr 2025]

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.
