Extended Data Fig. 4. Interaction of ER AF1 and AF2 domains with MAF.
a, Immunofluorescence showing the nuclear localization of AF1 and AF2 ER domains through the detection of the 6x His-tag. Scale bar, 20 μm. b, PLA of HA or 6x His-tag antibody alone or both antibodies together in MAF-overexpressing MDA-MB-231 cells transduced with AF1 or AF2 ER domains. Representative confocal microscopy images for PLA red signal and DAPI nuclear staining with magnified inset are shown. Scale bar, 50 μm; inset scale bar, 10 μm. c, PLA quantification. Each dot represents the average PLA signal from 64 to 208 nuclei per condition. n = 3 biological replicates. Bars represent mean ± sem. Statistical significance, two-tailed Wilcoxon rank-sum test.
