Function

Bromodomains, in general, function as acetyl-lysine binding domains to regulate gene transcription in chromatin. This particular bromodomain of CBP binds with relatively high specificity to Lys20-acetylated histone H4 (H4K20), though this preference is not well understood.

Disease

Relevance

Bromodomains have become a popular target for their role in human disease since they recognize an epigenetic tag.

Structural highlights

This protein is composed of two different domains -- the bromodomain (BrD) and the PHD finger. In this particular module for human CBP, the two come together to form such interactions that they function as a single structural unit.There are two that serve as a stable base for an extended interface established between the PHD finger and the BrD. This is a sample scene created with SAT to by Group, and another to make of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
