GtoPdb Ligand ID: 8236

Compound class: Synthetic organic
Comment: I-CBP112 is an inhibitor of the bromodomain-containing proteins CREB binding protein (CREBBP) and E1A binding protein p300 (EP300) and was developed by the Structural Genomics Consortium (SGC) [3]. The bromodomains facilitate binding of these proteins to acetylated lysine residues on histones and other proteins [4], interactions which underlie the function of these two transctiptional co-activators in the control of DNA replication and repair, cell growth, transformation, and development [1-2].
