m6A modification of non-coding RNA and the control of mammalian gene expression.
Coker H., Wei G., Brockdorff N.
The biology of non-coding RNA (ncRNA) and the regulation of mammalian gene expression is a rapidly expanding field. In this review, we consider how recent advances in technology, enabling the precise mapping of modifications to RNA transcripts, has provided new opportunities to dissect post-transcriptional gene regulation. With this has come the realisation that in the absence of translation, the modification of ncRNAs may play a fundamental role in their regulation, protein interactome and subsequent downstream effector functions. We focus upon modification of RNA by N6-methyladenosine (m6A); its readers, writers and erasers, before considering the differing role of m6A modified lncRNAs MALAT1 and Xist.
