== Function ==
[https://www.uniprot.org/uniprot/BRD2_HUMAN BRD2_HUMAN] May play a role in spermatogenesis or folliculogenesis (By similarity). Binds hyperacetylated chromatin and plays a role in the regulation of transcription, probably by chromatin remodeling. Regulates transcription of the CCND1 gene. Plays a role in nucleosome assembly.<ref>PMID:18406326</ref>

== Publication Abstract from PubMed ==
Developing stereoselective synthetic routes that are efficient and cost-effective allows easy access to biologically active molecules. Our previous syntheses of allele-selective bumped inhibitors of the Bromo and Extra-Terminal (BET) domain proteins, Brd2, Brd3, Brd4 and BrdT, required a wasteful, late-stage alkylation step and expensive chiral separation. To circumvent these limitations, we developed a route based on stereocontrolled alkylation of an N-Pf protected aspartic acid derivative that was used in a divergent, racemisation-free protocol to yield structurally diverse and enantiopure triazolodiazepines. With this approach, we synthesized bumped thienodiazepine-based BET inhibitor, ET-JQ1-OMe, in five steps and 99% ee without the need for chiral chromatography. Exquisite selectivity of ET-JQ1-OMe for Leu-Ala and Leu-Val mutants over wild-type bromodomain was established by isothermal titration calorimetry and X-ray crystallography. Our new approach provides unambiguous chemical evidence for the absolute stereochemistry of the active, allele-specific BET inhibitors and a viable route that will open wider access to this compound class.
