The bromodomain-containing proteins (BRD-proteins) belongs to family of 'epigenetic mark readers', integral to epigenetic regulation. The BRD-members contain a conserved 'bromodomain' (BRD/BRD-fold: interacts with acetylated-lysine in histones), and several additional domains, making them structurally/functionally diverse. Like animals, plants also contain multiple Brd-homologs, however the extent of their diversity and impact of molecular events (genomic duplications, alternative splicing, AS) therein, is relatively less explored.
