Applications N6-Methyladenosine is the most common internal modification of eukaryotic mRNA. The result of this modification is specifically recognized mRNA in the cytoplasm which regulates mRNA stability.N6-Methyladenosine is made when a protein complex containin the writer enzyme METTL3 adds a methyl group to adenosine. Two different eraser enzymes ALKBH5 and FTO can remove a methyl group to turn m6A bach into adenosine.
