Topoisomerase III-β is required for efficient replication of positive-sense RNA viruses

28 Jul 2020

Abstract excerpt

Based on genome-scale loss-of-function screens we discovered that Topoisomerase III-β (TOP3B), a human topoisomerase that acts on DNA and RNA, is required for yellow fever virus and dengue virus-2 replication. Remarkably, we found that TOP3B is required for efficient replication of all positive-sense-single stranded RNA viruses tested, including SARS-CoV-2. While there are no drugs that specifically inhibit this...
