Human recombinant BRDT, bromodomain-1, expressed as an N-terminal GST fusion protein. BRDT, like other human members of the BET family of chromatin-binding proteins (BRD2, BRD3, BRD4), comprises two bromodomains, protein modules that bind epsilon-N-acetyllysine residues. Mouse BRDT-1 (BRDT bromodomain 1) can bind simultaneously to two acetyllysine residues and, among the multiply acetylated histone tails tested, had the highest affinity for a histone H4 peptide acetylated at lysines 5 and 8 (H4K5AcK8Ac). Expression of BRDT is testis-specific and deletion of the mouse BRDT-1 causes abnormal spermatid development and sterility. BRDT’s functions in spermiogenesis include roles in broad, programmatic regulation of gene expression, mRNA splicing, chromatin remodeling, meiosis, formation of the chromocenter and post-meiotic genome repackaging. A three-month treatment of male mice with the BET family bromodomain inhibitor, JQ1, reversibly eliminated fertility, highlighting the potential of BRDT-specific inhibition as an approach for pharmacologic male contraception.
