Trithorax histone methyltransferase Ash1/ASH1L is tightly regulated because it activates developmental gene transcription and counteracts Polycomb silencing. In this issue of Structure, Lee et al. (2019) and Hou et al. (2019) report the crystal structure of ASH1L bound to its activator MRG15 and suggest a mechanism that releases ASH1L auto-inhibition.
