N6-Methyladenine DNA Modification in Drosophila
DNA N(6)-methyladenine (6mA) modification is commonly found in microbial genomes and plays important functions in regulating numerous biological processes in bacteria. However, whether 6mA occurs and what its potential roles are in higher-eukaryote cells remain unknown. Here, we show that 6mA is present in Drosophila genome and that the 6mA modification is dynamic and is regulated by the Drosop...
متن کاملCharacterization of eukaryotic DNA N6-methyladenine by a highly sensitive restriction enzyme-assisted sequencing
Although extensively studied in prokaryotes, the prevalence and significance of DNA N(6)-methyladenine (6mA or m(6)dA) in eukaryotes had been underappreciated until recent studies, which have demonstrated that 6mA regulates gene expression as a potential heritable mark. To interrogate 6mA sites at single-base resolution, we report DA-6mA-seq (DpnI-Assisted N(6)-methylAdenine sequencing), an app...
متن کاملN6-Methyladenine: A Conserved and Dynamic DNA Mark.
Chromatin, consisting of deoxyribonucleic acid (DNA) wrapped around histone proteins, facilitates DNA compaction and allows identical DNA codes to confer many different cellular phenotypes. This biological versatility is accomplished in large part by posttranslational modifications to histones and chemical modifications to DNA. These modifications direct the cellular machinery to expand or comp...

متن کاملSelective detection of N6-methyladenine in DNA via metal ion-mediated replication and rolling circle amplification.
N6-methyladenine (6mA) is reported as a potential epigenetic marker in eukaryotic genomes. However, accurate identification of the location of 6mA in DNA remains a challenging task. Here, we show that Ag+ can selectively stabilize the A-C mismatch and efficiently promote primer extension. In contrast, the complex of 6mA-Ag+-C is instable and therefore cannot be recognized by DNA polymerases, re...
