DRACH motifs are in black and non-DRACH motifs in red. , 2003) when sequencing a mouse cDNA library. This Review discusses the state of currently available long non-coding RNA annotations and the impact of emerging technologies such as long-read sequencing. Long non-coding RNA (lncRNA) was originally defined as the representative of the non-coding RNAs and unable to encode. Studies using this method have already altered our view of the extent and complexity of eukaryotic transcriptomes. To infer functional regulation by known and newly characterized ncRNAs, we exploited pre-mRNA abundance estimates from total RNA sequencing, revealing 316 microRNAs and 3,310 long non-coding RNAs.
