Gene: Top1 (DNA topoisomerase I) Rattus norvegicus
Symbol: Top1
Name: DNA topoisomerase I
RGD ID: 621246
Description: 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); PARTICIPATES IN irinotecan pharmacodynamics pathway; irinotecan pharmacokinetics pathway; INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 6-propyl-2-thiouracil; amitrole.
Type: protein-coding
RefSeq Status: VALIDATED
Previously known as: Ab2-086; DNA topoisomerase 1; topoisomerase (DNA) I
