Weissman2,5,9,10* Transcriptional adaptation (TA) is a genetic robustness mechanism through which mutant messenger RNA (mRNA) decay induces sequence-dependent up-regulation of so-called adapting genes. How cytoplasmically generated mRNA fragments affect nuclear transcription remains poorly understood. Using genome-wide CRISPR screens, we uncover ILF3 as an RNA binding protein connecting cytoplasmic mRNA decay and transcription during TA and show that it is required for a range of TA substrates. …
