TLDR
This study developed a cell-based crosslinking approach to determine at high resolution and transcriptome-wide the binding sites of cellular RBPs and miRNPs and revealed that these factors bind thousands of sites containing defined sequence motifs and have distinct preferences for exonic versus intronic or coding versus untranslated transcript regions.About:

TL;DR: It is found that a human circRNA, antisense to the cerebellar degeneration-related protein 1 transcript (CDR1as), is densely bound by microRNA (miRNA) effector complexes and harbours 63 conserved binding sites for the ancient miRNA miR-7.
Journal ArticleDOI
Predicting effective microRNA target sites in mammalian mRNAs
TL;DR: It is shown that recently reported non-canonical sites do not mediate repression despite binding the miRNA, which indicates that the vast majority of functional sites are canonical.
Journal ArticleDOI
The widespread regulation of microRNA biogenesis, function and decay.
TL;DR: This work has shown that the regulation of miRNA metabolism and function by a range of mechanisms involving numerous protein–protein and protein–RNA interactions has an important role in the context-specific functions of miRNAs.
Journal ArticleDOI
The multilayered complexity of ceRNA crosstalk and competition
TL;DR: Understanding this novel RNA crosstalk will lead to significant insight into gene regulatory networks and have implications in human development and disease.

TL;DR: It is shown that m6A is selectively recognized by the human YTH domain family 2 (YTHDF2) ‘reader’ protein to regulate mRNA degradation and established the role of YTH DF2 in RNA metabolism, showing that binding of Y THDF2 results in the localization of bound mRNA from the translatable pool to mRNA decay sites, such as processing bodies.

Conserved seed pairing, often flanked by adenosines, indicates that thousands of human genes are microRNA targets
TL;DR: In a four-genome analysis of 3' UTRs, approximately 13,000 regulatory relationships were detected above the estimate of false-positive predictions, thereby implicating as miRNA targets more than 5300 human genes, which represented 30% of the gene set.
Journal ArticleDOI
Most mammalian mRNAs are conserved targets of microRNAs
TL;DR: This work overhauled its tool for finding preferential conservation of sequence motifs and applied it to the analysis of human 3'UTRs, increasing by nearly threefold the detected number of preferentially conserved miRNA target sites.

TL;DR: These results suggest that metazoan miRNAs can reduce the levels of many of their target transcripts, not just the amount of protein deriving from these transcripts, and seem to downregulate a far greater number of targets than previously appreciated.
