Shining light on drug discovery: optogenetic screening for TopBP1 biomolecular condensate inhibitors

Abstract Human topoisomerase IIβ binding protein 1 (TopBP1) is a scaffold protein involved in DNA replication initiation, DNA repair, transcription regulation, and checkpoint activation. TopBP1 forms nuclear condensates that act as a molecular switch to amplify ATR activity and promote the activatio...
