Poly-combing the genome for RNA
Abstract
An unresolved question in mammalian epigenetic regulation is how ubiquitously expressed chromatin-modifying complexes such as Polycomb group complex 2 (PRC2) find their specific target sites across an intricate choreography of localization events in time and space. Two recent studies now provide critical new insights into an intriguing genome-wide role for RNA in PRC2 regulation.
