Overview of the classification and molecular mechanisms of m6A methylation. m6A RNA methylation is regulated by 3 different key enzymes, corresponding writers, erasers, and readers, which perform the functions of adding, deleting, or recognizing m6A, respectively. The consequences of m6A methylation lead to multiple processes in RNA metabolism and expression, including RNA splicing, miRNA processing, nuclear export, translation, stability, and RNA decay.
