DNA-sequence-specific erasers of epigenetic memory
Abstract
How epigenetic regulators find their specific targets remains a challenging question. Two parallel studies show that REF6, a plant H3K27me3 demethylase, binds a specific DNA motif via its zinc-finger domains and recruits the SWI/SNF-type ATPase BRAHMA, demonstrating a sequence-specific recruitment mechanism for a chromatin-modifying complex.
