Bromodomain(BRD)
A bromodomain is an approximately 110 amino acid protein domain that recognizes acetylated lysine residues, such as those on the N-terminal tails of histones. Bromodomains are responsible in transducing the signal carried by acetylated lysine residues and translating it into various normal or abnormal phenotypes. Bromodomain-containing proteins can have a wide variety of functions, ranging from histone acetyltransferase activity and chromatin remodeling to transcriptional mediation and co-activation.
