The native MORF complex is a H3K23-specific HAT. a A diagram of MORF with the MORFN region indicated. b The MORF complex subunit composition. c Purified native MOZ and MORF complexes from K562 cells shown by silver staining. d Confirmation of the subunits of the native purified MORF complex by Western blots using specific antibodies. Source data are provided as a Source Data file. e HAT activity of native MORF complex from K562 cells on the indicated H3 peptides. Liquid HAT assays, in which reactions were spotted on P81 filters and counted by scintillation as counts per minute (CPM). f HAT activity of the MORFN complex overexpressed in 293T cells on indicated H3 peptides. g Cartoon showing interrelated activities of the adjacent DPF and MYST domains. The MYST domain acetylates primarily H3K23 and has some HAT activity on H3K14, whereas MORFDPF binds to unmodified H3 or acylated H3K14, preferring H3K14cr (see below). Error bars indicate the range from duplicate samples, n = 2 independent experiments
