Abstract
It is now evident that transcriptional gene regulation usually requires the re-organization of chromatin architecture. Increasing evidence suggested various kinds of RNAs are involved in this process. Especially the nascent RNAs retained at their site of transcription can serve as a scaffold for organizing transcriptionally either favorable or unfavorable chromatin structures. An emerging concept of phase separation explains how these chromatin structures can be maintained as physically discrete subcompartments within membrane-less nucleoplasm. Evidences that support the crucial role of nascent RNAs in the formation of phase-separated condensates are now rapidly growing.
