TLDR
Non-coding RNAs seem to be particularly abundant in roles that require highly specific nucleic acid recognition without complex catalysis, such as in directing post-transcriptional regulation of gene expression or in guiding RNA modifications.
Abstract
Non-coding RNA (ncRNA) genes produce functional RNA molecules rather than encoding proteins. However, almost all means of gene identification assume that genes encode proteins, so even in the era of complete genome sequences, ncRNA genes have been effectively invisible. Recently, several different systematic screens have identified a surprisingly large number of new ncRNA genes. Non-coding RNAs seem to be particularly abundant in roles that require highly specific nucleic acid recognition without complex catalysis, such as in directing post-transcriptional regulation of gene expression or in guiding RNA modifications.

Chromatin signature reveals over a thousand highly conserved large non-coding RNAs in mammals

TL;DR: It is demonstrated that specific lincRNAs are transcriptionally regulated by key transcription factors in these processes such as p53, NFκB, Sox2, Oct4 (also known as Pou5f1) and Nanog, defining a unique collection of functional linc RNAs that are highly conserved and implicated in diverse biological processes.

Modular regulatory principles of large non-coding RNAs

TL;DR: This work synthesizes studies to provide an emerging model whereby large ncRNAs might achieve regulatory specificity through modularity, assembling diverse combinations of proteins and possibly RNA and DNA interactions.

Intron-encoded, antisense small nucleolar RNAs: The characterization of nine novel species points to their direct role as guides for the 2'-O-ribose methylation of rRNAs

TL;DR: Nine additional members of the snoRNAs identified are intron-encoded, contain the characteristic box C and box D motifs and exhibit long complementarities to conserved sequences in mature rRNAs, supporting the conclusion that the duplex structure provides the 2'-O-methyltransferase with the appropriate site-specificity on the substrate.

Classical and novel approaches to the detection and localization of the numerous modified nucleotides in eukaryotic ribosomal RNA.

TL;DR: Progress is outlined towards developing a method whereby reverse transcription shows characteristic pausing at most of the 2'-O-methylation sites in human and Xenopus 18S rRNA, which is likely to be applicable to vertebrate and yeast ribosomes.

No evidence that mRNAs have lower folding free energies than random sequences with the same dinucleotide distribution

TL;DR: This work investigates whether mRNA has a lower estimated folding free energy than random sequences, and shows that the predicted free energy is not significantly different from random sequences with the same dinucleotide distribution.

Mapping to nucleotide resolution of pseudouridine residues in large subunit ribosomal RNAs from representative eukaryotes, prokaryotes, archaebacteria, mitochondria and chloroplasts.

TL;DR: The juxtaposition of the conserved sites for psi with the two important functions of the ribosomes, codon recognition and peptide bond formation, implies an important role for psi in ribosome function.

A computational approach to identify genes for functional RNAs in genomic sequences.

TL;DR: This work developed a machine learning approach using neural networks and support vector machines to extract common features among known RNAs for prediction of new RNA genes in the unannotated regions of prokaryotic and archaeal genomes and achieved a significant improvement in accuracy.
