(A) Lysates prepared from asynchronous HeLa cells were subjected to pull-down with GST, GST-Scc1 (281–420), or GST-Scc1 (281–420)-SA2 (80–1060), followed by immunoblotting with antibodies for Wapl and GAPDH, and CBB staining. (B) Lysates prepared from HEK-293T cells transiently expressing Wapl-Flag in the forms of WT and the 3xEGE mutant were subjected to pull-down by GST or GST-Scc1 (281–420)-SA2 (80–1060), followed by immunoblotting with the antibody for the Flag-tag, and CBB staining. Irrelevant lanes were removed. (C) MBP-Wapl (1–630) in the forms of WT and the 3xEGE mutant were subjected to pull-down by GST, GST-Scc1 (281–420), or GST-Scc1 (281–420) -SA2 (80–1060), followed by immunoblotting with the antibody for MBP, and CBB staining. (D, E) U2OS-LacO cells transiently expressing the indicated proteins were stained with antibodies for the Flag-tag and Myc-tag, and DAPI. Example images are shown (D). The fluorescence intensity ratio of Wapl-Flag/EGFP at the LacO repeats was quantified in 30 cells for each condition (E). (F, G) U2OS-LacO cells transiently expressing the indicated proteins were stained with antibodies for the Flag-tag, Myc-tag, and DAPI. Example images are shown (F). The fluorescence intensity ratio of SFB-CENP-U/EGFP at the LacO repeats was quantified in 30 cells for each condition (G). Data information: The white arrows point to the LacO repeats (D, F). Scale bars, 10 µm (D, F). Statistics were performed using unpaired Student’s t-test (E, G). Means and SDs are shown (E, G). Source data are available online for this figure.
