Functioni

N6-methyltransferase that methylates adenosine residues of some mRNAs and acts as a regulator of the circadian clock and self-renewal of embryonic stem cells. N6-methyladenosine (m6A), which takes place at the 5'-[AG]GAC-3' consensus sites of some mRNAs, plays a role in the efficiency of mRNA splicing and processing and mRNA stability. M6A regulates the length of the circadian clock: acts as a early pace-setter in the circadian loop by putting mRNA production on a fast-track for facilitating nuclear processing, thereby providing an early point of control in setting the dynamics of the feedback loop. M6A also acts as a regulator of mRNA stability: in embryonic stem cells (ESCs), m6A methylation of mRNAs encoding developmental regulators, results in transcript destabilization, maintaining the groung state of ESCs, thereby promoting self-renewal of ESCs.2 Publications
