N6-Methyladenine is a DNA epigenetic modification that involves the addition of a methyl group to the sixth position of adenine. N6-Methyladenine plays an important role in distinguishing host DNA from exogenous DNA and controls many biological functions, such as DNA replication, transcription, mismatch repair, and chromosome replication. N6-Methyladenine can be used for the kidney diseases[1][2].
