Sequence alignment of Brd2 BD2. Sequence alignment of Brd2 BD2 with a selected number of Bromodomains including Brd2 BD1, Brd4 BD2, hsGCN5, scGCN5, hsCBP, hsP/CAF, hsBRG1 and the two components from TAFII250. The sequences were aligned based on the experimentally determined three-dimensional structures of these bromodomains, highlighted in green. The secondary structure of Brd2 BD2 is indicated above the alignment. Residues identical in all sequences are shown in red and residues conserved are coloured in blue and residues corresponding to β Z sheet (hsBRG1) and helix π D are represented in yellow. The two amino acids insertion is indicated by triangle symbols (▼).
