The Xist lncRNA Exploits Three-Dimensional Genome Architecture to Spread Across the X Chromosome


Mammalian genomes encode thousands of large noncoding RNAs (lncRNAs), many of which regulate gene expression, interact with chromatin regulatory complexes, and are thought to play a role in localizing these complexes to target loci across the genome. A paradigm for this class of lncRNAs is Xist, which orchestrates mammalian X-chromosome inactivation (XCI) by coating and silencing one X chromosome in ...
