TRANSCRIPTIONAL REPRESSION BY A SECONDARY DNA BINDING SURFACE OF DNA TOPOISOMERASE I SAFEGUARDS AGAINST HYPERTRANSCRIPTION

Transcriptional repression by a secondary DNA binding surface of DNA topoisomerase I safeguards against hypertranscription

Abstract Regulation of global transcription output is important for normal development and disease, but little is known about the mechanisms involved.DNA topoisomerase I (TOP1) is an enzyme well-known for its role in relieving DNA supercoils for enabling transcription.Here, we report a non-enzymatic Rack Accessories function of TOP1 that downregula
