The human fat mass and obesity-associated protein FTO catalyses the removal of m6A in vitro and in vivo. It is a member of the non-haem FeII/a-ketoglutarate (a-KG)-dependent AlkB family demethylases that mainly catalyse oxidative demethylation of N-alkylated nucleic acid bases. FTO oxidizes m6A to hm6A and f6A in RNA in a step-wise manner. FTO was identified in several genome-wide-association studies to be associated with obesity and type II diabetes.
