Chromatin-associated RNA (caRNA) is a newly identified class of RNA stably linked to chromatin and responsible for maintaining the higher order structure of euchromatic regions in an accessible form (Schubert et al., Mol Cell 48, 434 - 444, 2012). This section provides a pipeline of ...
Here, we generate a resource of genome-wide RNA-DNA and DNA-DNA contact maps in human cells. These maps reveal the chromosomal domains demarcated by locally transcribed RNA, hereafter termed RNA-defined chromosomal domains. Further, the spreading of caRNA is constrained by the boundaries of ...
Intriguingly, NSUN5 directly interacts with and deposits m5C on CTNNB1 caRNA (chromatin-associated RNA). NSUN5-induced recruitment of TET2 to chromatin is independent of its methyltransferase activity. The m5C modification on caRNA is subsequently oxidized into 5-hydroxymethylcytosine (5hmC) by ...
However, the structural contribution of RNA to chromatin organization remains undisputed: a large proportion of chromatin by mass corresponds to RNA (Holmes et al., 1972), mostly belonging to the loosely termed chromatin-associated RNA (caRNA) class. The functional roles of caRNAs are hinted by...
