Treacle controls the nucleolar response to rDNA breaks via TOPBP1 recruitment and ATR activation
Abstract
DNA double-strand breaks in ribosomal DNA repeats is associated with repression of ribosomal RNA synthesis. Here the authors reveal a cooperation between TOPBP1 and Treacle in the signaling cascade that triggers transcriptional inhibition and nucleolar segregation in response to rDNA breaks.
