FIG. 3.

Colocalization of dUTX with the elongating form of RNA polymerase II (A through D), contrasted with the engaged but paused form (E through H). (B) Costaining for the Ser2-phosphorylated CTD of the elongating form of RNA polymerase. (C and G) Immunolocalization of dUTX on polytene chromosomes. (D) Merge of panels B and C, showing colocalization of Ser2-phosphorylated Pol II and dUTX. (F) Costaining for the engaged but paused Ser5-phosphorylated CTD of Pol II. (H) Merge of panels F and G, showing only partial colocalization. (A and E) Corresponding phase-contrast images.
