Expression of GFP- or mRFP-tagged CP190 in transgenic flies. (A-B) A third instar larva expressing eGFP-tagged CP190 (A), or mRFP-tagged CP190 (B). (C-D) Fluorescent signals of CP190eGFP in a salivary gland (C), and in the nucleus of a salivary gland cell (D). (E-F) Fluorescent signals of CP190mRFP in a salivary gland (E), and in the nucleus of a salivary gland cell (F). (G-I) The distribution of CP190mRFP (G) and Mod67.2 (H) proteins at the tip of X chromosome. The polytene chromosome was prepared from a y2 3rd instar larva. The white arrows point to the y locus where contains a copy of the gypsy insulator. The red arrow point to the location that contain only CP190 protein but do not contain Mod67.2 protein.
