A SGO2 localizes at the centromeres of spermatocyte-derived and maternal chromosomes. Oocytes were fixed at metaphase I and stained for SGO2 (green), ACA (centromeres, magenta), and Hoechst33342 (DNA, blue). Images were reconstructed in 3D and viewed from the top and side of the metaphase plate. Note that signals are interpolated in z. B PLK1 localizes at the kinetochores of spermatocyte-derived and maternal chromosomes. PLK1 (green) localization was investigated as in (A).
