FTO-Mediated Formation of N6-Hydroxymethyladenosine and N6-Formyladenosine in Mammalian RNA

N(6)-methyladenosine is a prevalent internal modification in messenger RNA and non-coding RNA affecting various cellular pathways. Here we report the discovery of two additional modifications, N(6)-hydroxymethyladenosine (hm(6)A) and N(6)-formyladenosine (f(6)A), in mammalian messenger RNA. We show that Fe(II)- and α-ketoglutarate-dependent fat mass and obesity-associated (FTO) protein oxidize ...

N6-Methyladenosine in Nuclear RNA is a Major Substrate of the Obesity-Associated FTO

We report here that fat mass and obesity-associated protein (FTO) has efficient oxidative demethylation activity targeting the abundant N6-methyladenosine (m(6)A) residues in RNA in vitro. FTO knockdown with siRNA led to increased amounts of m(6)A in mRNA, whereas overexpression of FTO resulted in decreased amounts of m(6)A in human cells. We further show the partial colocalization of FTO with ...

Identification of N6,N6-dimethyladenosine in transfer RNA from Mycobacterium bovis Bacille Calmette-Guérin.

There are more than 100 different ribonucleoside structures incorporated as post-transcriptional modifications, mainly in tRNA and rRNA of both prokaryotes and eukaryotes, and emerging evidence suggests that these modifications function as a system in the translational control of cellular responses. However, our understanding of this system is hampered by the paucity of information about the co...

Dual Fluorescence from N6,N6-Dimethyladenosine

The adenosine derivative N6,N6-dimethyladenosine (DMA) shows dual fluorescence in solvents of different polarity. In addition to the “normal” fluorescence at 330 nm, another band is observed at 500 nm. The long wavelength emission dominates in aprotic solvents but is dynamically quenched by protic solvents. Steady-state and lifetime measurements show that the emissions originate from two excite...

N6-methyladenosine Modulates Messenger RNA Translation Efficiency

N(6)-methyladenosine (m(6)A) is the most abundant internal modification in mammalian mRNA. This modification is reversible and non-stoichiometric and adds another layer to the dynamic control of mRNA metabolism. The stability of m(6)A-modified mRNA is regulated by an m(6)A reader protein, human YTHDF2, which recognizes m(6)A and reduces the stability of target transcripts. Looking at additional...
