Figure 2. Localization of HCP-6 throughout the cell cycle. (A-P) Wild-type embryos showing DNA (blue), anti-HCP-6 (red), or anti-HCP-3 (green) staining, or merged images. Colocalization between HCP-6 and HCP-3 is shown as yellow. (A-D) At interphase, this antigen is visible as punctate dots distributed throughout the nucleus. (E-H) In prophase nuclei, HCP-6 forms two parallel lines on individual prophase chromosomes, a pattern suggesting centromere localization. (I-L) At metaphase, the HCP-6 protein is present on the poleward faces of the metaphase plate. (M-P) During anaphase, HCP-6 remains associated with the separating groups of sister chromatids. (Q-S)
hcp-3(RNAi) embryos stained with anti-HCP-6 (red). In the absence of HCP-3, HCP-6 does not assemble onto mitotic chromosomes properly. Bars, 1 μm.
