A new approach is used to target BET family bromodomains which are found in transcriptional regulators where they mediate the recognition of acetyl-lysine chromatin marks. Structural data reveal how the compound JQ1 binds to the bromodomain of BRD4. BRD4 has been implicated in a subtype of human squamous carcinomas, and JQ1 is found to inhibit the growth of BRD4 dependent tumours in mouse models.
