Abstract


N6-methyladenosine (m6A) RNA methylation has become a progressively popular area of molecular research since the discovery of its potentially essential regulatory role amongst eukaryotes. m6A marks are observed in the 5'UTR, 3'UTR and coding regions of eukaryotes and its mediation has been associated with various human diseases, RNA stability and translational efficiency. To understand the implications of m6A methylation in molecular governance, its functionality and mechanism must be initially understood. m6A regulation through its readers, writers and erasers as well as an insight into the potential "cross-talk" occurring between m6A and previously well documented regulatory molecular mechanisms have been characterized. The majority of research to date has been limited to few species and has yet to explore the species- and tissue specific nature or mechanistic plasticity of m6A regulation. There is still a tremendous gap in our knowledge surrounding the mechanism and functionality of m6A RNA methylation. Here we review the formation, removal, and decoding of m6A amongst animals, yeast, and plants while noting potential "cross-talk" between various mechanisms and highlighting potential areas of future research.
