Crosstalk between RNA metabolic pathways: an RNOMICS approach

Eukaryotic cells contain many different RNA species, Nuclear pre-mRNAs and cytoplasmic mRNAs carry genomic information to the protein synthesis machinery, whereas many stable RNA species have important functional roles. The mature, functional forms of these RNA species are generated by post-transcriptional processing, and evidence has been accumulating that there are functional links between the various processing pathways. This indicates that there are regulatory networks that coordinate different stages of RNA metabolism. This article describes the aims and results, to date, of the European RNOMICS project as an example of an integrated approach to investigate these links.
