We analyze small molecule ligand binding to ATAD2 bromodomain by molecular dynamics and protein crystallography. We observe a previously unexplored conformation of the binding pocket upon rearrangement of the gatekeeper residue Ile1074. Minor differences in the ligands result in binding with different plasticity of the ZA loop.
