Brd4, a reader of histone acetylation, is a transcriptional co-activator implicated in the maintenance of embryonic stem cells (ESCs). A study now shows that Brd4 is dispensable in mouse ESCs maintained in ground state pluripotency, and that cooperative activity of Tet1/2 and ESC-specific transcription factors compensates for its loss.
