Additional Information

BRD9 is a bromodomain containing protein that form a small sub-branch of the bromodomain family tree. Human BRD9 contains a single bromodomain and has five isoforms that are produced by alternative splicing. Little is known about BRD9 function but it has been implicated in chromatin remodelling as part of the SWI/SNF complex. (http://www.thesgc.org/chemical-probes/I-BRD9)
