DNA methylation represents a major type of DNA modifications that play key roles in diverse biological processes. With the recent development of highly selective and sensitive bioanalytical techniques, N⁶-methyladenine (6mA) has been characterized as an important internal DNA modification dynamically occurring in multiple eukaryotes including humans. Increasing evidence has indicated that 6mA may act as a novel epigenetic modification involved in regulation of development, stress response and diseases such as cancer and neurodegenerative disorders. We review herein the recent advances in the detection and functional studies of 6mA modification, with special emphasis on its biological consequences and human health relevance as well as its dynamic regulation by various types of methyltransferases, demethylases and 6mA-binding proteins. It can be envisaged that further chemical and biological studies of 6mA modification will lead to a better understanding about its potentially important roles in normal and pathological biological processes.
