N6-methyladenosine modification destabilizes developmental regulators in embryonic stem cells.

ABSTRACT: N(6)-methyladenosine (m(6)A) has been identified as the most abundant internal modification of messenger RNA in eukaryotes. m(6)A modification is involved in cell fate determination in yeast and embryo development in plants. Its mammalian function remains unknown but thousands of mammalian mRNAs and long non-coding RNAs (lncRNAs) show m(6)A modification and m(6)A demethylases are required for mammalian energy homeostasis and fertility. We identify two proteins, the putative m(6)A MTase, methyltransferase-like 3 (Mettl3; ref. ), and a related but uncharacterized protein Mettl14, that function synergistically to control m(6)A formation in mammalian cells. Knockdown of Mettl3 and Mettl14 in mouse embryonic stem cells (mESCs) led to similar phenotypes, characterized by lack of m(6)A RNA methyl
