TLDR
It is reported here that human METTL14 catalyzes m6A RNA methylation, and together with METTL3, the only previously known m 6A methyltransferase, these two proteins form a stable heterodimer core complex ofMETTL3-14 that functions in cellular m6 a deposition on mammalian nuclear RNAs.Abstract:
Certain adenosine residues within mammalian RNAs undergo reversible N6 methylation. Two methyltransferase enzymes, METTL3 and METTL14, as well as the splicing factor WTAP are identified as core components of the multiprotein complex that deposits RNA N6-methyladenosine (m6A) in nuclear RNAs.read more

TL;DR: In a unified mechanism of m(6)A-based regulation in the cytoplasm, YTHDF2-mediated degradation controls the lifetime of target transcripts, whereasYTHDF1-mediated translation promotion increases translation efficiency, ensuring effective protein production from dynamic transcripts that are marked by m( 6)A.

Post-transcriptional gene regulation by mRNA modifications
TL;DR: N6-adenosine methylation directs mRNAs to distinct fates by grouping them for differential processing, translation and decay in processes such as cell differentiation, embryonic development and stress responses.

TL;DR: 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.
