The Arabidopsis acetylated histone-binding protein BRAT1 forms a complex with BRP1 and prevents transcriptional silencing

Abstract

Transposons and repetitive sequences are typically subject to transcription silencing. Here, Zhang et al. find that the bromodomain-containing protein BRAT1 forms a complex with BRP1, recognizes histone acetylation and acts to prevent transcriptional silencing in Arabidopsis.
