Human recombinant BRD4, tandem construct comprising bromodomains 1 and 2, expressed as an N-terminal GST fusion protein. BRD4, like other human members of the BET family of chromatin-binding proteins (BRD2, BRD3, BRDT), comprises two bromodomains, protein modules that bind epsilon-N-acetyllysine residues. BRD4-2 (BRD4 bromodomain 2) is the more C-terminal of the two domains in BRD4. The ubiquitously expressed BRD4 functions as a transcriptional regulator with roles in cell cycle progression and has recently been shown to be an atypical kinase that can phosphorylate RNA Pol II. Chromosomal translocations that produce BRD4-NUT fusion proteins are implicated in causation of a rare and aggressive cancer, NUT midline carcinoma. Selective inhibitors of BRD4/BET family bromodomains are showing promise as possible therapeutic agents for cancer and inflammation.
