A DNA adenine demethylase impairs PRC2-mediated repression of genes marked by a specific chromatin signature

{{output}}
Background: The Fe (II)- and α-ketoglutarate-dependent AlkB family dioxygenases are implicated in nucleotide demethylation. AlkB homolog1 (ALKBH1) is shown to demethylate DNA adenine methylation (6mA) preferentially from single-... ...
