Effects from depleting chromatin remodelers and histone chaperones, as indicated (wide range shown in A, on recruitment of Su(H)-GFP in Notch-ON nuclei (expressing NΔECD) of larval salivary glands. Different OSA RNAi stocks used in C are denoted by (1) and (2). In all conditions except Moira RNAi (A) nuclei exhibit a bright accumulation of Su(H)-GFP at a single locus when imaged live. Scale bars (yellow) = 5 µm. Percentage of Notch-ON nuclei retaining a single clear band of Su(H)-GFP when the indicated RNAi is co-expressed with NΔECD. For each genotype, 5 nuclei from each of 10 glands were scored (50 nuclei total). **** A significant fraction of nuclei lost the fluorescent band when core components of the BRM complex were perturbed; p<0.0001, two-tailed Fisher's exact test calculated using the raw (non-percentage) scoring data.
