The recent discovery of reversible mRNA methylation has opened a new realm of 
post-transcriptional gene regulation in eukaryotes. The identification and 
functional characterization of proteins that specifically recognize RNA 
N6-methyladenosine (m6A) unveiled it as a modification that cells utilize to 
accelerate mRNA metabolism and translation. 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. Other mRNA modifications, including 
N1-methyladenosine (m1A), 5-methylcytosine (m5C) and pseudouridine, together 
with m6A form the epitranscriptome and collectively code a new layer of 
information that controls protein synthesis.
