The bromodomain and extra terminal domain (BET) family of proteins, including BRD2, BRD3, and BRD4, play a key role in many cellular processes, including inflammatory gene expression, mitosis, and viral/host interaction by controlling the assembly of histone acetylation-dependent chromatin complexes. JQ1 displaces BET proteins from chromatin by competitively binding to the acetyl-lysine recognition pocket of BET bromodomains.1,2 Enantiomerically pure (+)-JQ1 binds to BRD4 bromodomains 1 and 2 with Kd values of ~50 and 90 nM, respectively, whereas the (−)-JQ1 stereoisomer has no appreciable affinity to BET bromodomains.1 JQ1 has been used as a chemical probe to investigate the role of BET bromodomains in the transcriptional regulation of oncogenesis.1,2,3,4,5 See the Structural Genomics Consortium (SGC) website for more information.
