[[http://www.uniprot.org/uniprot/BRDT_HUMAN BRDT_HUMAN]] Testis-specific chromatin protein that specifically binds histone H4 acetylated at 'Lys-5' and 'Lys-8' (H4K5ac and H4K8ac, respectively) and plays a key role in spermatogenesis. Required in late pachytene spermatocytes: plays a role in meiotic and post-meiotic cells by binding to acetylated histones at the promoter of specific meiotic and post-meiotic genes, facilitating their activation at the appropriate time. In the post-meiotic phase of spermatogenesis, binds to hyperacetylated histones and participates in their general removal from DNA. Also acts as a component of the splicing machinery in pachytene spermatocytes and round spermatids and participates in 3'-UTR truncation of specific mRNAs in post-meiotic spermatids. Required for chromocenter organization, a structure comprised of peri-centromeric heterochromatin.<ref>PMID:9367677</ref> <ref>PMID:15647849</ref> <ref>PMID:22901802</ref> | [[http://www.uniprot.org/uniprot/BRDT_HUMAN BRDT_HUMAN]] Testis-specific chromatin protein that specifically binds histone H4 acetylated at 'Lys-5' and 'Lys-8' (H4K5ac and H4K8ac, respectively) and plays a key role in spermatogenesis.

+ | Bromodomain-containing proteins are considered atypical kinases, but their potential to interact with kinase inhibitors is unknown. Dinaciclib is a potent inhibitor of cyclin-dependent kinases (CDKs), which recently advanced to Phase III clinical trials for the treatment of leukemia. We determined the crystal structure of dinaciclib in complex with CDK2 at 1.7 A resolution, revealing an elaborate network of binding interactions in the ATP site, which explains the extraordinary potency and selectivity of this inhibitor. Remarkably, dinaciclib also interacted with the acetyl-lysine recognition site of the bromodomain testis-specific protein BRDT, a member of the BET family of bromodomains. The binding mode of dinaciclib to BRDT at 2.0 A resolution suggests that general kinase inhibitors ("hinge binders") possess a previously unrecognized potential to act as protein-protein inhibitors of bromodomains. The findings may provide a new structural framework for the design of next-generation bromodomain inhibitors using the vast chemical space of kinase inhibitors. | ||
