Figure 1. — JIL-1 localizes to actively transcribed regions on polytene chromosomes. (A) Immunolocalization of JIL-1 (red) and Pol IIo^ser2 (green) on wild-type (wt) polytene chromosomes; arrows indicate sites of colocalization. (B) Immunolocalization of JIL-1 (red) and Pol IIo^ser5 (green) on wild-type polytene chromosomes; arrows indicate sites of colocalization. (C) Detailed view of a section of the chromosomes in B. (D) Immunolocalization of JIL-1 (red) and Pol IIa (green) on wild-type polytene chromosomes; arrows indicate Pol IIa sites that do not exhibit JIL-1 binding. (E) Detailed view of a section of the chromosomes in D. (F) Immunolocalization of JIL-1 (red) and Pol IIo^ser2 (green) on ecdysone-induced puffs at E74EF and E75B. (G) Immunolocalization of JIL-1 (green) and phosphorylated H3S10 (H3pS10) (red) on ecdysone-induced puffs at E74EF and E75B. The puffs are indicated with arrows. DNA is stained with DAPI (blue) in all images.
