    Summary
    Enables DNA topoisomerase type I (single strand cut, ATP-independent) activity and chromatin DNA binding activity. Involved in several processes, including cellular response to luteinizing hormone stimulus; nucleic acid metabolic process; and response to gamma radiation. Located in dense fibrillar component and fibrillar center. Orthologous to human TOP1 (DNA topoisomerase I). [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.
