Bromodomain testis-specific protein (BRDT)

Testis-specific chromatin protein which specifically binds histone H4 acetylated at'Lys-5' and'Lys-8' (H4K5ac and H4K8ac, respectively) and plays a key role in spermatogenesis (PubMed:22464331, PubMed:22901802). Required in late pachytene spermatocytes: plays a role in meiotic and post-meiotic cells by binding to acetylated histones in the promoter of specific meiotic and post-meiotic genes, facilitating their activation in the suitable time (PubMed:22901802).

In the post-meiotic phase of spermatogenesis, binds to hyperacetylated histones and participates in their overall removal from DNA (PubMed:22901802). Also recognizes and binds a subset of butyrylated histones: able to bind histone H4 butyrylated in'Lys-8' (H4K8ac), although it's unable to bind H4 butyrylated in'Lys-5' (H4K5ac) (By similarity).
