| Abstract | BRPF1 plays a scaffolding role in transcription. We report on fragment screening by high-throughput docking to the BRPF1 bromodomain which resulted in six chemotypes with very favorable ligand efficiency (0.45-0.50 kcal/mol per non-hydrogen atom). Twenty crystal structures of BRPF1/ligand complexes show structural conservation in the acetyllysine binding site, common binding motifs, and unusual interactions (e.g., the replacement of a conserved water molecule). The structural information is useful for the design of chemical probes. |
