BRD4_HUMAN Plays a role in a process governing chromosomal dynamics during mitosis (By similarity).

Publication Abstract from PubMed

The identification of a novel series of small molecule BET inhibitors is described. Using crystallographic binding modes of an amino-isoxazole fragment and known BET inhibitors, a structure-based drug design effort lead to a novel isoxazole azepine scaffold. This scaffold showed good potency in biochemical and cellular assays and oral activity in an in vivo model of BET inhibition.
