Abstract Appropriate control of the transcriptome is essential to regulate different aspects of gene expression during development and in response to environmental stimuli. Fast accumulating reports are recognizing and functionally characterizing several types of modifications across transcripts, which have created a new field of RNA study named epitranscriptomics. The most abundant modification found in messenger RNA (mRNA) is N6‐methyladenosine (m 6 A). m 6 A addition is achieved by a large methyltransferase complex (MTC). The m 6 A‐MTC is composed of the methyltransferases METTL3 and METTL14 as the catalytic core, and several protein factors necessary for its correct catalysis, which include WTAP, RBM15, VIRMA, HAKAI, and ZC3H13. To fully appreciate the relevance of this modification, it is important to dissect the basis for the MTC function as well as to define its interaction with other cellular partners. Here, we summarize previous and recent knowledge on these issues to provide a guide for future research and put forward ideas on the flexibility and specificity of this process.
