    Summary
    Predicted to enable DNA topoisomerase type I (single strand cut, ATP-independent) activity. Predicted to be involved in DNA replication and DNA topological change. Predicted to be located in mitochondrion and nucleoplasm. Predicted to be active in mitochondrial nucleoid. Orthologous to human TOP1MT (DNA topoisomerase I mitochondrial).

    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.
