GSE122696: The NuRD complex suppresses transcriptional noise during lineage commitment [RNA-Seq]

• Organsim mouse
• Type RNASEQ
• Target gene
• Project ARCHS4

Here we set out to define the biochemical and functional diversity encoded by one such group of proteins within the mammalian Nucleosome Remodelling and Deacetylation (NuRD) complex: Mta1, Mta2 and Mta3. We find that, in contrast to what has been described in somatic cells, MTA proteins are not mutually exclusive within ES cell NuRD and, despite subtle differences in chromatin binding and biochemical interactions, serve largely redundant functions. ES cells lacking all three MTA proteins represent a complete NuRD null and are viable, allowing us to identify a highly previously unreported function for NuRD in reducing transcriptional noise, which is essential for maintaining a proper differentiation trajectory during early stages of lineage commitment.
