Biochem/physiol Actions

Bromodomains (BRDs) are protein-interaction modules that "read" ε-N-lysine acetylation motifs, such as those found in the N-terminal tails of histones. BRDs have been identified in chromatin-modifying enzymes (such as histone acetyltransferases (HATs)) as well as in transcription factors that regulate genes for cell cycle progression, signal transduction, apoptosis, and inflammation. Proteins containing bromodomains have been implicated in various diseases, such as cancers, inflammatory diseases and neurological diseases. Bromosporine is a broad spectrum BRD inhibitor. In HeLa cells, bromosporine accelerates FRAP recovery of BRD4 and CREBBP at 1μM. For full characterization details, please visit the Bromosporine probe summary on the Structural Genomics Consortium (SGC) website.
