Comparison of GFP-MHCKs and GFP-myosin II distribution during cytokinesis. In the early-to-mid stage of cytokinesis (upper row), none of the GFP-MHCKs localizes to the furrow, opposite to that of the GFP-myosin II (M). GFP-MHCK-A and -C, instead, enriches to the polar protrusions at this stage (A and C, upper row). At the later stage of cytokinesis (lower row), GFP-MHCK-C suddenly appears at the posterior region of the two daughter cells (C), similar to what is observed for GFP-myosin II cells (M). The scale bar shown in the image is 5 μm. The observation described is summarized in the sketch shown below the images.
