Fig. 2

a Normalized average microarray signal intensities detected upon binding of the GST-tagged MORC4 CW domain to the peptides carrying indicated PTMs. Data are represented as mean values +/− S.D. from n ≥ 3 independent arrays. See also Supplementary Data 1. b Cartoon representation of CW in complex with histone H3K4me3 tail. c Peptide pull-down assays of the GST-tagged MORC4 CW domain using the indicated histone H3 peptides. Images are representative of three independent experiments with similar results (n = 3). Source data are provided in a Source Data file. d, e Superimposed 1H,15N HSQC spectra of the 15N-labeled WT MORC4 CW domain collected upon titration with the histone H3K4me3 (d) and unmodified H3 (e) peptides. Spectra are color coded according to the protein-to-peptide molar ratio. f Representative binding curve used to determine Kd values by tryptophan fluorescence. g Binding affinities of MORC4 CW for the indicated histone H3 peptides measured by tryptophan fluorescence. Data are represented as mean values +/− S.D. from three independent experiments (n = 3). Source data are provided in a Source Data file.
