DEFINITION
  • DNA topoisomerase I (765 aa, ~91 kDa) is encoded by the human TOP1 gene. This protein plays a role in the regulation of DNA topology.NCI
DesignNote
  • DNA topoisomerases I and II relax negative and positive supercoils; TOP1 breaks single DNA strands, TOP2 breaks duplex DNA. Specifically inhibited by the antitumor plant alkaloid CPT, when TOP1 breaks the DNA backbone bond it forms a protein-DNA link (a tyrosyl oxygen joins to a DNA strand end phosphorus).
